Well, ended up with the non fight flex model, the decision was made for me as NO ONE seemed to have the flight flex. And as for the motor, i couldn't find any one selling the stick mount adapter, i could have got it at a later date, but i was in an impatient mood, so went for the park 370 4100KV inrunner. Unfortunately i struggled to find a better quality gear box, so ill wear out the stock one first now.
The build went quickly and was surprisingly easy (the first ARF plane ive built that actually was ARF) Though i made a few modifications and adjustments, first up i reinforced the tail bush, with two circles of epoxy either side. I also stiffened the elevator and rudder push rods with some carbon fiber over the V bends, and finely i opted out of using the supplied tape for the ailerons, and used some proper hinges instead. Every thing went together very smoothly, and very straight (thanks to the model, not me

)
But ive just run in to a couple of problems

First up, i have dual rates on my TX, but only for 2 channels, and i cant adjust the rudder, but before its on full, the control arm is touching the fuse, so this will weaken over time if i cant find a way round it.
The second thing that has baffled me completely, is that it tells you to set the ailerons throws, at different measurements up and down? but surely when one is up the other will be down the same amount? Or have i missed something?
Did a quick power test (just holding it vertical) with a relatively flat lipo, and it seemed to have plenty of power on offer, not sure what the all in weight is, but id say it was holding its self up at just under half. Towards 3/4 throttle its really trying to pull out of my hand, and full throttle feels very unstable, but i cant weight to give it a try. Sadly i too am having the long weight till the rain goes. But this will give me time to think about those two issues.
Glad to hear your flys well in the wind, ill weight for a still day to maiden mine, but i do love how wind adds a whole new challenge to flying, and makes some moves possible that arnt on still days.
Ill let you know how it flys as soon as the weathers good.
