    Some of the guys asked about flying without engine so here are some video clips showing RC Hand Launch Gliding.( HLG)
    In case u don't know - all models are fully under RC control at every moment to make this possible.

    Hand launch, fly circuit, fly to hand, bleed off speed, catch.

    Discus launch (DLG) to height with a lightweight side arm launch (SAL) type glider, as used in most thermal flight competitions.

    Actually .. .it's not a Salsa, it's a Salome in that clip

    It was quite difficult locate a decent video of a model in a thermal, where it was still close enough to see what happens. Usually when we hit one, the plane is already a dot. :)

    BTW ... the ideal thermal source is the black tarmac of a car park, or tarcloth factory roof, in sunny conditions. Ploughed earth can be OK. Heat rising from trees in evening great thermally, but risky location to fly too close.
    Summer or winter are both good because it is not heat that does it, it's temperature differences in still air.
    OTOH we usually slope soar it it's windy. ;)
    I think you can get a good about hand launch gliding in these. Like I said before, all you need to fly is the right kind of a plane and a radio. :D
