RE: two blade prop for alpha
The firewall damage was done by bad landings by the first owner and me. Then, I landed with only 1 engine mount bolt screwed in one day. The other 3 had backed out due to those unbalanced 3 bladed Evo props. The damage went unseen for a while, I guess. The Xtra Easy 2 isn't fuel proofed and it got fuel soaked over time and that is probably what made some layers of the 1/4" ply develop cracks. I epoxied 1/8 ply over the entire front of the firewall as it looked like a major hack job to remove it. Before that, I clamped the original firewall with medium CA squirted in the cracks overnight. Finally, I put triangular stock in the corners on both sides, and fuel proofed it all. It flew well after that.
Hey Wings, you still mad at me over the RTF comments???
