Hi, mine has flown with the CG in the recommended position, lovely and smooth, but had to put in a reasonable amount of down trim to get it to fly straight and level
I will play about with the CG in further flights to see what's the best compromise
There was no shortage of power from the Turnigy 430 kv on a 17x12 prop and 6 cells,verticals were effortless, and I highly recommend this motor.
Will be interested how everyone else gets on with this model.
