First flight: I used a Align High-Power 40C 7.4V 1900mAh for power. CG as per manual. The plane took off but was uncontrollable and crased hard on the paved runway. Only damage was the 3 blade prop lost 1 blade and minor scratches.
Second flight: This time with a Turnigy 30C 11.1v 1000mAh and a 2 blade 7x5 master airscrew prop. The plane took off easily and flew a bit jumpy. There was gentle crosswind. The plane is very fast. It was not easy to get a proper slope for landing and ended in some bushes without damage.
Third flight was similar. this is a quite fast plane and you need fast fingers during final approach and landing. I think it is better to hand launch w/o wheels and belly land on grass.
iWhen it is flying it is easy to spot, I was worried about the dark color, but the bent wing is visible at all times (almost).
I liked it.
