Hello all,

I'm building my first plane. A Kadet LT-40. I've decided to go electric. I've followed the kit, except for a couple mods for the electric stuff.

I've covered it, and now I'm to the point of final assembly.

I don't know why, but I decided to use the Great Planes hinges, the ones with the pins, instead of the hinges that came with the kit.

The instructions said to cut grooves for the hinges.. which I did. I test fitted everything before I covered it, and everything seemed OK.

Then I covered the surfaces, and I've started finally assembly. Now it seems the hinge action is stiff, it squeaks. The elevator springs from extreme up, to extreme down, with tension in between. And I noticed this morning one of the hinges actually broke. Gosh Darn it!

Anyway... I'm punting the hinges I installed. And I'll install the kits hinges...

What I need to do, is cut hinge grooves that I know are going to be aligned and accurate. I need the control surfaces to move easily and smoothly.

So.. After that long diatribe..

What are some good technics, tools, tips, for cutting hinge grooves. And for installing hinges afterwards....


Thanks in advance,

Lyndon
