    Robbie, I'm a Hobbyking aficionado, thanks to you pointing me in their direction two years ago. However after over 30 successful orders with them, my latest order appeared to be taking a lot longer than normal. I found out why on Tuesday last when I received a letter from Customs & Excise to say they'd held my parcel pending proof of what I'd paid. I sent the invoice to them and got charged €23 VAT plus a €6 post office fee.

    I don't know if I was just unlucky (I'd had over 30 orders up to now without getting caught for customs) or if they are cracking down on parcels from outside the EU in the ongoing efforts to screw every last cent out of us to pay banker's debts.

    I'm going to hold off ordering anything else from Hobbyking for a while.

    Im no more a fan of them than anyone else. Just that charger is a good one, and they (hobbyking) are good for the batteries. I had the odd delayed order before alright. I only usually only buy small items from them anyway.

    The customs are like a lottery at times. I get the t-rex 600 in from the US, and other items, no problem. Then got caught for batteries that cost far less.

    @Dave: I got the charger at the hobby ship on Capel Street. Ended up with the one you suggested. However I am furious as the guy told me to connect it a certain way and it does not work. It is just when i read your post again i noticed that lead is missing. I am fuming!
    2 days and not a battery charged...
    I still have to put the whole thing together, i guess it will be tomorrow.

    Found a solution by combining some other leads that came with charger. First battery charged quite fast and balanced (30 minutes +). charging second one now.

    I've had some good and bad experiences with that model shop in Capel Street. It usually depends on what sort of humour the guy who runs it is in:rolleyes:. While he has started branching out into electric models lately, he mainly caters for the nitro/petrol model side of the hobby.

    When you charged your battery, did you set the charge rate a "1"? Any higher and you risk either damaging the battery and shortening its life or a fire if it overheats and goes pop.

    As for the quick charging time you had last night, this is because these brand new batteries come from the factory with a "storage charge" in them, i.e. they are charged up to half their capacity. Therefore you only had to half charge the battery to bring it up to full. When you have your first flight and go to recharge, it will take longer to bring it back to full.

    You're getting there though. Almost time for that first flight:). First time flying is an exciting and nerve wracking experience. Its great to see this big plane flying at your control, but (unless you are flush with money), it will make your heart pound too as you know that a mistake might write the plane off and there goes a sizable chunk of money. The wind is due to die down this evening and be light Monday and Tuesday too which would be good for your maiden flight.

    Hi Dave,
    The rate I used was 1.3 Amps, but I will adjust it at 1Amp for next time. I had seen a video where a lad was using exact same charger so I wasnt too lost with it. Bought the needed lead online as well as the one allowing to parallel load 2 batteries of the same kind and capacity, at least that will save me charging time for 2 batts.
    I noticed very quickly that in this hobby it is a must for one to become some type of Mc Guyver (referring to the TV series :D) as you run in a bunch a little problems and you have to be creative to solve them. As i was going to adjust the cable for the rudder, the little screw that tightens the cable broke but with the reciving piece stuck on the cable. Without being able to remove it I was facing cutting the cable (disaster as then needed to source one). Finally after 1 hour of soft attemps i used brute force in a smart way and removed the annoying piece. Was left with having to replace that part as i dont have this type of stuff lying around, so i made an adaptation with an electric domino, which seemed to work fine but after checking all controls and trims etc i noticed the brass cracked on that part, so I am off to a model shop and possibly Maplin to find some longer term solution...... I am exhausted just by writing all this :D.
    Weather tomorroe might be OK (wind down and sunny) except very cold. I will be out of town from monday to thursday so weather permiting i'd like to give it a go tomorrow either with you lads or somebody from the club.
    I will keep you informed of my evolution here.
    cheers

    :D Welcome to the world of rc flying, where nothing goes as planned:D

    That model shop on Capel Street sells "Clevis's" which are an alternative (and more widely used form) of attaching the control rod to the control horn on the rudder/elevator. I bought some from him a few weeks back as the supplied plastic ones on my planes were starting to crack from wear and tear. I bought metal ones from him that are a lot sturdier. The only thing to watch is that they are the correct size for your control rods, i.e. not too big or they won't screw on. Buy some fuel line too so you can slide it over the clevis and hold it together.

    If you go for it tomorrow at your club, make sure that the guy teaching you has flown a glider before as they are a different beast to faster moving and aerobatic planes. Gliders need a gentle hand and their reaction times are slow but that will suit you while learning. The golden rules are:

    1. Fly upwind of you at all times, i.e. the wind is in your face. If you let a glider get behind you with a following wind, it is hard to get her back to you.

    2. Get the plane up high as altitude is your friend. If you make a mistake, then you will have time to recover. If you fly too low, you won't. I'd recommend a minimum of 100 feet up, or say two fully grown trees on top of one another. The higher the better though, but not so she's a speck in the sky;).

    3. Stay well away from trees and powerlines.

    4. The Radian needs a very long approach to land so allow for this.

    5. Keep all control inputs slow and smooth. No need to jerk the sticks as she is not a responsive plane. Start with slow circles to get the feel of her and then extend into figures of 8.

    6. If you get into trouble, do not use the motor as this will just speed you into more trouble. Let go of the sticks and she will right herself, providing she isn't too low of course - see '2' above!

    7. If she starts roller coastering, i.e. pitching up and down, wait until she is on the "downward slope" and then put her nose down a little until she regains airspeed and then level her off.

    Look it might seem like there's a lot to remember, but its like learning to drive a car. At first, its a lot to take in but before you know it, it'll be second nature.

    Its 1 C you want if its a 1300 mah battery, which is one times the battery Capacity. Not 1 amp.

    So a 1300 mah battery, which is 1.3 amps, means you charge it at 1.3 amps to charge it in about 1 hour. There is nothing to stop you charging at lower rates, but the ususal is 1 C.

    I have charged batteries at 2 C a few times, for a half hour charge. But its almost always 1C i charge at.

    A 2200 mah battery will be a charge rate of 2.2 amps for a 1 hour charge, and so on.

    So does this mean that the 1.3 figure i plugged in was correct for the 1300mah battery?

    Radian is now fixed - got some parts from radiocontrolledshop.ie today and fixed it. All controls working as they should. Just need to perform a range check. Got the small case for the DX6i.
    Also got the pheonix simulator.
    Time to fly...


  • Closed Accounts Posts: 3,399 ✭✭✭Kashkai


    Nice one Miami. I must get over to radio control shop some day to see what they have in stock (I presume its ok to drop in?). The guys who run that also ran my local flying club but it appears to have been kicked off its flying field and is thereby defunct.

    The Phoenix sim is quite good for practice but flying in the real world is a different kettle of fish as the wind, the sun in your eyes, people/dogs distracting you etc affect you. Saying that however, my daughter learned to fly on the Phoenix sim and when it came time to fly my supercub, it was pretty easy for her.

    The WOT4 is a great plane and one I've been tempted to buy myself but leave her be for the moment as she will be a big step up from flying the Radian, and you've yet to do that;). One step at a time, eh, or you could let me "mind it" for you:D.

    Dave & Robbie any chance you guys want to fly today?
    Weather seems gorgeous dont know about the wind.
    That shop Dave is the best I have seen in Dublin for electric planes and helis.I had seen 3 or 4 other shops in the last 2 weeks.


  • Registered Users Posts: 291 ✭✭Miamiheat


    OH and if you guys wanna try the WOT4 (promise you wont break it) I can bring it as well. although you will need to bring a nattery for it and some velcro to secure it. otherwise she is ready to go.

    Yes 1300mah charge at 1.3 amps, 2200mah = 2.2 amps, 5000mah = 5 amps for 1C charging and so on.

    I was flying at 8 this morning, it was calm enough. Fairly windy when i did the last flight at 12 mid day though.

    Its very windy here now in navan. Not a nice one for starting. Maybe it will calm later.


  • Closed Accounts Posts: 3,399 ✭✭✭Kashkai


    Very windy here in Kildare at the moment.

    Miami, I know you're itching to fly but trust me, it would be a handful flying for Robbie and myself in gusting winds, never mind a guy starting out.

    Just hold off until the winds are calm-ish. You'll have enough on your plate flying the Rad for the first time without having the wind causing you bother by throwing the Rad around the sky.

    I'm under the weather at the moment with a lousy cold, shivers, headache etc and I wouldn't be up to flying as I can hardly talk and my ears are blocked. Therefore I wouldn't be much of a teacher today:D

    Hi Miami

    Well did you go to the Phoenix Park and try to fly???

    Next weekend is looking promising with calm winds.


  • Registered Users Posts: 291 ✭✭Miamiheat


    Hi Dave,
    Sorry for no responding sooner I was on a business trip to Germany.
    I did not get to fly as when I got the the park on Sunday the wind had picked up horribly and the lads with nitro were packing up. One of them helped me by checking the plane and helping me reverse some channels as I must have messed around with radio and i had changed a few settings.
    So it is ready to go. Saturday I am comited to fishing from noon forward, but I am available early. Sunday I am technically free.


  • Registered Users Posts: 291 ✭✭Miamiheat


    Oh and they recommended I set the dual rates on the radio.
    Can you help? (by telling me what rates to set?)
    cheers


  • Closed Accounts Posts: 3,399 ✭✭✭Kashkai


    Hi Miami

    I don't think you messed anything up with the radio. It probably came that way and the channels for the elevator/rudder had to be reversed anyway. This is normal. On some of my planes, they came with the control surfaces operating the way they should while others had to have one or all channels reversed. This is part of the set up routine for any new plane. While it's simple to do, it can be easily overlooked even by those who think they are experienced flyers like me. I had a brand new Mustang last year and after a cursory check, I thought all was well. So I launched her and pulled back to climb, except I hadn't checked the elevators direction of movement. It should have been reversed but I didn't do it and so instead of climbing away at full throttle, it dived into the ground. Luckily, damage wasn't to bad but it stopped me getting too complacent.

    As for dual rates, this is the method of setting how much you want your control surfaces to move. There is a low and a high setting. I usually set my low rate at 70% and high at 100%. When launching, keep her on low rates so you won't pull her up into a loop over you and into the ground behind you. The Radian is not an agile plane and so she turns fairly slowly but she can climb and dive quite quickly. Have a look at your DX6i manual and see if you can set the dual rates. Then try and fix the dual rates to the one switch so you'll have the same low and high rate on your rudder/elevator.

    I have Daddy duties Saturday morning bringing my kids to horse riding and swimming lessons. I plan on going to the Dublin mountains in the afternoon to try slope soaring my Radian. I'm free Sunday though.


  • Registered Users Posts: 291 ✭✭Miamiheat


    it is Sunday and almost 4AM: just got back from fishing.
    I will be out of commission this morning but may want to try this afternoon. Give me a heads up if you plan to go anywhere to fly.
    cheers

    AHHHHH
    Finally got her to fly....
    What a pleasure!
    BIG THANK YOU to Robbie and son who coached me through it. We got about 1 hour flying time out of 2 batteries.
    Cant wait to start again - I have a feeling the week will be long...


  • Closed Accounts Posts: 3,399 ✭✭✭Kashkai


    Congrats on a successful maiden flight:).

    Always a good one when you bring the plane home in one piece.


  • Registered Users, Registered Users 2 Posts: 900 ✭✭✭Xpro


    Lads any of you fly in curragh kildare? i was there a few weeks ago, nicely done up grass strip and there was plent of rc planes and helis around.


  • Registered Users Posts: 291 ✭✭Miamiheat


    I believe Dave flies there.

    Lads any recommendation on 2200mah batteries (any particular brand?)
    3S 11.1V?


  • Registered Users, Registered Users 2 Posts: 669 ✭✭✭Ilyushin76


    Hobbyking is probably the best place to get batteries if your not in to much of a hurry for them.These batteries are very good and I have being using this brand for nearly a year and they are still going good .Make sure you check the battery dimensions with the size of your battery bay in your plane so the fit .You might need an adaptor for the battery to connect to your planes lead too.What type of plane are they for ?

    These are the actual ones i got, and used in the radian. They are the same physical size as the ones Ilyushin76 has linked. So either will fit in the radian.


    They are a tight fit in the radian at first, but they will fit. No need to use the velcro strap, it wont reach anyway.


    These adaptors will save you cutting off the xt60 plugs, and soldering on EC3 plugs.


  • Closed Accounts Posts: 3,399 ✭✭✭Kashkai


    I use the nano tech batteries as they are ligther than other equivalent batteries but give more power and longevity in my experience.


  • Closed Accounts Posts: 13,422 ✭✭✭✭Bruthal


    Two of the standard ones i linked can be got for one of the nano tech ones though that have the higher C rating though.

    For the radian, the standard ones are fine, it will only be using 16 or 17 amps, or about 8C. We have the one we got about 2 years now. Used it in the t- rex 450 as well, although the nano tech would be better for that.

    hi guys im a beginner like yer selves, i started with a firebird http://www.hobbyzone.com/rc_planes_hobbyzone_firebird_commander_2.htm but outgrew it now have a skysurfer http://www.bananahobby.com/1937.html and the dynam 330 extra http://www.dynam-rc.com/products/airplane/extra.htm Need batterys for both. The skysurfer nosed dived on me last year and i lost the prop and the nut holding the prop. The motor was hanging out when i found it also . I bought repairs for it but doesnt seem to get air for me. Looking to get a nice radio system, nothing too expensive though.


  • Registered Users, Registered Users 2 Posts: 3,057 ✭✭✭civdef


    The skysurfer is also known as the Hobbyking Bixler (virtually the same). Bits from one will fit the other.

    Motors, maybe this:
    http://www.giantcod.co.uk/black-mantis-b2836-2200kv-inrunner-brushless-motor-p-403216.html
    or
    http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=127&productname=

    with a 6x4 prop should get you out of bother.


    If you take the bunch of washers out of the front (there for centre of gravity) a 3s 2200mah should work really well, if you don't want to take them out, go for a 1300mah 3s.

    Maybe post some pics of the damage - might help with suggestions on fixes?

    How much do you want to spend on the radio?

  • Registered Users, Registered Users 2 Posts: 1,672 ✭✭✭tonydude


    guess id pay between 100 to 150

    ill get some pics up when i can, not much nose damage just cant figure out the motor /prop combo

    Need a plane for holidays in Spain (can stay stored there).
    Alicante area so beach and mountain.
    Glider # 2 ?
    any other recommendations?

    thanks


  • Registered Users, Registered Users 2 Posts: 1,672 ✭✭✭tonydude


    Can someone help me on what set up id need to make my skysurfer into a brushless set up, motor/esc/battery/charger. How to install it into the plane , how do you secure the motor to the plane frame? i understand that the battery must be strong enough to power the motor and the amp of the motor must suit the esc but thats as far as i know. Its hard to understand all the charging and storing (longtime) of those lipos too . I ve 2 dead ones at the moment :mad:


  • Registered Users, Registered Users 2 Posts: 3,057 ✭✭✭civdef


    The skysurfer comes as standard with a brushless setup? What have you at present?

    Here are some good videos on build and setup (some of them are the first of a series):
