I recently picked up a started kit. The wing was already framed and and wing halves joined together. I am going to install two aileron servos in the wing. What would be the best way to try to cut or channel each rib to route aileron extension wires since this was not done while the wing halves were apart? Any help is appreciated.

I generally cut a slot in each rib using small drill and making 2 holes about 1/2" apart and then use the exacto knife with a #11 blade to remove the wood between the holes. The slot should be big enough so the connector just fits through. Some like to be able to remove the servo if needed by using an extension cable long enough to reach the servo bay which would allow easy removal.

Ditto, but I make the holes larger. You never know when you may need to remove or replace the servo, and even if you DID put a string in there to pull the new wire through (or didn't lose the string somehow) it's much easier to thread the new servo wire through a decent sixe hole.

I had to cut ribs to run servo wires and used a hand held paper punch to make two holes spaced a little wider than the servo connector then used my exacto to cut out the balsa between the holes. Made an excellent oval shaped hole. 0___0 Another line across the top but can't do it on the puter. A paper punch cuts thru balsa nicely.

I've done it just like upnflyin says on my current build

Does anyone have any secrets to putting extensions in the wings of a funtana 40 because the wings come preglued.

Feed it through with piano wire with a loop on the end tapeing end to wire so it won't get hung up on ribs on the way through!

The best trick I've learned is to get a pretty good length of chain. The chain with the little round balls like what you wear dog tags on. Tie a piece of string onto the chain and the chain pulls the string around corners, through offset holes etc. It works great. I've never had a problem threading extensions using this method. I'm telling you, you'll have a new regard for the "dog tag" type chain and you'll have several of them. One for the field box and one for the shop..
