I still do on some occassions. It's pretty fun to fly. It's very different from a traditional 5" freestyle or race rig. So far, I've only crashed on soft ground. I don't think will do well on concrete.. Arms are damn thin.. It's more or less the same betafpv's sub250g 5inch x-knight or racer x et5. But I think, these newer frames might be more durable. I don't really know. I don't dare crashing it on any solid surface. So far, it only crashed on soil and tree branches.

Hey Sorry for the late reply. I haven't been flying or building lately. The world is just goig to chaos. :( Yes, I tried it with a 1550mAH 3s lipo. I get around 8minsish.. THe problem with these motoros is they can't hanlde heavy weight. It flies like a mountaineer with super massive backback going up everest. I would also need to be careful with throttle as going full throttle draws a huge amount of current and sags the voltage. It takes a while for the voltage to recover. Other than that, it can fly. It losses it's reactiveness and punch but you do gain flight time. 850mAH is the best balance of flight time and manuverability. ~ 5mins..

For cruising and long range, I'm considering building a 3S lithium ion pack. It would probably just as heavy as a 1550mAH 3s but imagine a having 3000mAH! :D For now my building is on hold, I can't really order anything until this corona thing subsides. :(

It's possible but tight. But it should work out with taller standoffs.

Thanks. :) I'm actually looking into building a 5 or 6inch long range with a Druckbär frame but with a beefier 2207 or bigger motor. I can really see that weight helps a lot with efficieny. These ultralights react like speed-demons and flies like feather. I'm really mindblown. :)
