I've been told that the retract rails and engine rails in the Model Tech P-51 can be a little weak, and should be replaced with Maple or Hardwood.
What if I were to apply or wrap these rails (if possible) with Fiberglass tape and either CA or Epoxy? This should add some strength, right?
Besides, I think replacing the existing rails will be tedious and could weaken the remaining structure, specifically, the nose.
Thoughts?
Well, I spose I had a related problem when I fly it a couple of days ago. Two of the engine mounting screws came loose, so I had to abandon flying for the day.
Probably my fault, as I used those Dubro screws that work great in glass / plastic mounts, but not so well, it seems, in hardwood bearers. I've put captive nuts and bolts in now. I have a Saito 72 installed, which works fine, and isn't over-vibrating.
Yes, the retract rails might be a bit weak, but I haven't had any problems there yet.
It's definitely a great flier though, and lands very easily.
