erm, this isnt really a tip of anything, but id seariously advise not carshing it!
also, this is a tip, add a strong servo to the tail, thats one hell of a lot of rudder. i only had a 148, which i admit worked ok but it got allot of slop very quick, so i changed it on sun morning to a new 148 and that wernt a good move, on a little tumble about 25 foot up it when into n inv spin and doinked itself on the deck. at center stick the rudd had about the same amount of movement as in the picture, so i coulnt pull out in time. hit the deck not too hard but totaled it, in that mid canopy section there were no formers left, and allot of dust! lol
