I have the Great Planes C182 ARF for my second plane. The Avistar ARF is my first one. I have two questions perhaps some of you can answer...

1. I've been trying to fit the hinges in the slots that are pre cut. I'm sliding them in as shown, with the length going in the slot so the hinges go in deeper. If there is too much of a gap between the trailing edge of the wing/vstab/hstab and the control surface, how deep can you cut the slot? I'm afraid of going thru the frame into the open area between the ribs of the structures.

2. On my Avistar they just had you wick thin CA without drilling holes, but this kit says you should drill a hole in the middle of each slot to help the CA wick through. The material of the hinges seem identical. Is the drilling really necessary?

Thanks in advance!!

Cutting the slot all the way thru and into the open cavity won't hurt, just be sure to stick a pin thru the middle of each hinge so it stays centered. Drilling a hole does help the CA to wick in better but it's not really needed if you apply the CA carefully and give each drop a second or two to soak in.

Cut the slots deep enough so that the gap between wing and aileron (or horz stab and elevator) is minimal. It does not matter if the slot goes through the balsa piece into the open area. Use THIN CA. I have never felt that you need to drill any holes. The THIN CA wicks thru the hinge entirely. If you have an extra hinge, try it with some scrap balsa.

Thanks guys!

There is an article by Minnflyer on installing CA hinges here on RCU. It's worth looking at. Make sure you use fresh thin CA and old CA can have problem wicking due to higher viscosity. You can insert small or medium T-pins along the hinge gap to maintain an accurate gap width when applying CA.
