Hi JFetter,

As a confirmed Impact enthusiast I look forward to your project with interest. My only word of caution is that I really have some misgivings that you can make the 5kg weight limit with your chosen setup. My two Impacts, one Hackered and the other Pletted both need careful prop and spinner selection to be legal. This is using 10S 5300 TP Prolites. You are correct in that the Impact feels solid but the potential weakness is that the internal glass skin is very thin and if cut the foam core underneath is easily cracked, spalled or otherwise damaged leading to a failure. Both my models have been fitted with a balsa ladder crutch in place of the foam one as I feel that this allows better access for rudder closed loop and servo lead runs but otherwise have been built pretty much as per the kit instructions. I did add wing and tail adjusters though.

Good luck!

Malcolm
