FPS and ROF gearbox set -up

CAVEMAN_69

Im planning to build a gearbox that is about 320 to 325 FPS with a high ROF. I just dont know what upgrade parts should I buy to acquire the FPS and ROF. Any suggestions is much appreciated. Thanks in advance.:)

depends how much you want to spend really. a not too much expensive option is ehobbyasia guarder high speed motor $28 and set of high speed gears and sp90 spring. makesure cylinder, cylinder head and piston head all match up so you dont lose pressure through leaks. good 9.6v 1600mah or 7.4v 2000mah battery.

Saying "all match up" you mean the same brand of parts? thanks for the advice mate...;)

Expect this to be in much better detail later tonight.

Starting with the shell, if you want a high ROF - Get a decent shell, one that takes 7mm or 8mm bearings.

Bearings - Obviously get them to match the shell size (simple right?) Don't buy a cheap brand, I'm a fan of KA ones myself.

Gears - I run XYT gears in all my AEGs, ok they're not high speed gears, but they're feckin' great! Stay away from cheap brands, nobody likes stripped gears.

Shims - Shim the gearbox right, it cuts down on wear and noise. I always get two sets, a G&P copper shim set and Guarder steel shims. G&P sets have nice .1mm and .2mm shims, perfect for getting everything just right.

Piston - I'm a huge fan of the Element clear polycarbonate piston with the AOE mod done to it. I've found doing the AOE mod gets me 3rps more without needing to upgrade other internals.

Piston Head - I run Systema Duracon ones in my AEGs as they're about a fiver (well they were when I last got one) and very very reliable, one with bearings would be best.

Cylinder - Get a bore-up one, this will help you keep consistency in your set up, make sure to get one for the right lenght of barrel too. Element are fairly good

Cylinder head - Once again, get a bore-up one and when fitting it, a small layer of PTFE tape works wonders. I forget what brand I'm using atm.

Air Nozzle - As with the above two, get a bore-up one, for the same reasons.

Spring guide - A bearing spring guide is great, it'll help stop springs twisting and breaking (believe me, not fun at all), make sure it's compatible with the gearbox first!

Tappet Plate - get a reinforced one, not Systema, they're sh*ite, in my experience, had one snap in half after two, yes two rounds, since went back to an Element one.

Feck me - I'm starting to sound like an ad for Element!

Switch set - A large capacity one is ideal, with a high ROF, you'll be expecting large current loads and you want the wiring to be able to handle that. I usually make my own with somevery f*cking expensive cable (haven't a clue what the brand is, can't remember)

Motor - Get a Guarder M120 or if you're Thermo a TM Eg3000... The Guarder motor is very reliable and has a good bang for your buck. The TM Eg3000 is three times more expensive and much faster.

Spring - Guarder M90's are great, but you may need to cut a bit off to make it perfect, if you do, file the cut end.


Essay over.
