Installed 440 pushrods last night and the aileron linkages are now very tight and they do not flex under (test) load nearly as badly as the 2mm rods. Wing is ready to fly. I still have to epoxy the inside of the tank compartment to firm up the landing gear mount area and the engine compartment where I had to grind for the YS. All linkages are in and feel OK. I still cringe with the pull/pull elevator but have been multiply assured it will be fine. I would prefer to mount the tank amidships to minimize change in CG. Is the weight needed in the nose?

Hello All,
Remember, if you are going to use the pull-pull setup on the elevators, to replace the ends of the control horns with something that overhangs enough to put the clevis pin right above the hingeline, not behind it. The elevator tracking will work much better, then. If I remember correc tly, I used the ennd pieces from the DuBro #867 horn. You have to buy four of them ... oh well.
Take Care,

Dean, et al,
While the pickoff point on the hinge line is the very best solution for slack wires at extremes of throw, you can accomplish the same thing by offsetting the pull/pull pickoff point on the servo wheel. It's a pain in the tail to do, and requires some experimenting to get it right, but it does work OK and prevents flutter and bad stuff from happening without spending the extra $20 for extra hardware.

Finally got around to cutting the cowling for the YS 110. When I moved the motor forward to get the spinner clearance I wanted, the front of the cowl hits the head so I had to completely open up the front of the cowl instead of using the dual slot as I hoped. Oh well. It looks fine and fits well now. I also didn't cut the three slots in the back, since I opened the front up so much, I also opened the back. I need to paint the gear plate area inside black so that model looks finished. Test flights should be late this week or early next week. Icepoint gear and canopy are going to work well and look very good.

We have a HobbyTown and the owner actually does fly so he has a clue. The Tony is still around, has no radio gear, motor, or retracts in it but could be made flyable in about 2-3 hours. I have actually considered getting it out and flying it but have too many other things to do and not enough time.
