Hey Fellas,
My Great Planes RV-4 was flying so sweet. she tracked beautifully and I could not get her to drop a wing no matter how slow I flew. She was a huge hit at the field with my club members but on the 10th flight, at the bottom of a split-S, the horizontal stab broke on both sides of the fuselage just outside the sheeted portion. Aircraft went in hard and was totaled. While I was building the kit, it occurred to me that the balsa they provided foe the leading edge of the stab was way too light. But I decided to go with it. After the aircraft was covered in Mono-coat, I still thought the stab was a bit flimsy. Well, If I build another, I will beef up the stab. I would even consider sheeting the entire stab as opposed to just the center section. I had to add 1.5 oz of lead to the tail anyway to get her to balance out with a OS .50sx in front. Anyway, It was a super kit that looked as good in the air as it did on the ground. Easy to build and a super flier. Just a word of caution to those who are currently building this little sports car. Give some thought to the stab area so it does not happen to you. razorback11
