Getting close to finishing. Retracts work great. It includes restrictors. Get about 20 cycles out of a tank. Had to put washers under the two screws closest to the root to get it to sit paralel to the wing when retracted. No problems with the old school control rods. I did set the ele. horns at an angle for better geometry. There are no referance marks on the firewall for mounting the engine. So if you've built a couple models or had a couple of the more involved ARFs, you shouldn't have a problem here. This is a nice looking ARF. I'll get some pics if I can get the camera away from my daughter, its hers.
