Mega Mosquito Build Part 3, Engine Mount and Fin Prep




Here's the finished engine mount.
Kevlar was added under the upper centering ring.









TIP: Sand off just the forward corner tip of the fin tab to fit over the Kevlar line loop.





This is the thicker center fin layer.
The middle pieces are removed to reduce the weight.



Here's how the fins will lay up.
The center piece is 3/32" thick, the outside skins are 1/16".

All glued and laminated the fins are lust under 1/4" thick.


I though it would be a good idea to somehow curve the root edge to fit the body tube better.
You can't sand a curve in the root edge with the central fin tab in the way.
I figured I'd "step" the outside laminate pieces. It won't take much of a offset angle to fit the curve of the body tube.
I sanded a very slight angle on the root edge of the outside skins.
(Be sure you "mirror" the outside laminate pieces!)
