Thanks for the compliments !!! The wings will start to get tippy or see-saw back and forth once you cut the throttle to around 25%, and you try to maintain altitude (a nose high slow flight with the wings alternately going left and right every second or so is what it turns out to be). You will see, try it high and just be ready with getting out with throttle and a slight down-elevator if needed. This thing is on rails at any throttle above 25% [&:] The decent rate of this plane at idle is STEEP, keep that nose down and keep the speed at all costs, tippy wings down low and slow to the ground is bad. Hahahahaha.

As far as the CG I would say that you are best off at where you are 96mm for the first time out. If you running off of grass too, you just need to have a lot of up-elevator while taxiing, or you will nose in. This is mostly due to the high main-gear, but CG is part of it.

Oh yeah one last thing, if you are going with full throws on the elevator as the manual shows, be sure to have either your dual-rates set up with nice and low throws for low-rates, OR have a ridiculously high about of exponentials dialed in. I was at full throws or more on elevator, with 55% expo's this first flight, not bad, but I dialed it up to 70% for the second and third flights [X(]
