They are able to fly indoor but also inside gymasium. So, when it's raining for weeks, I am happy to have them! This is may be the logical behind the fact that I fly Jets AND super small planes.
This peanut size plane is electric, with fully proportionnal radio, weight 22 grammes ready to fly. The 2 hand made spoked wheels weight 0,41 gr !
It is quite a unique jet since it uses a turbine 1/3 the size of the smallest commercialy available turbines. The result is a 1 kg jet made of foam while all other kerosene jets weight at least 8kg and are made of fiberglass or other hightech materials. It is fun to watch but morover increadible to hear !
They have the same performances than the turbine jets except that they miss the increadible sound & smell of Kerosene, but... I can fly them on all possible RC fields where Turbine jets will not be allowed.
