I didn't mean to take over your thread Don, I figured a couple of other pictures of the "Stinker" from different views might be helpful.
The plane flies very well with a TT40 and a 9X6 prop. With the slicker air-frame than a quickie,,,it would probably do better with a 8.5 X 7 without loading the engine too much. It actually has very good slow speed characteristics also and lands smoothly.
I appreciate you posting them in the thread. And I really appreciate the comments about the performance with the TT Pro 40.
I had a Kangke F3D/30 (which was grandfathered into Q-40 Sport) with a TT Pro 40 and the best props on it were the 7.4 x 8 and 7.4 x 8.25 ... In terms of sport props, the APC 8x8 was actually pretty good but required smooth turns.
If you ever try the 7.4 props, make sure you change the rear bearing first as they will turn in the 18K+ range on the ground.
Feel free to post comments about building the Stinger. I would love to see pictures of how you did the aileron servo and the other radio gear as well as the wing hold downs and the hatch details.
As I mentioned, I have plugs made for the wing and stab and hope to make composite parts by the summer. But a lot more guys are building from foam again because of the 424 rules. I think two sets of cores and a set of plans for $30 is a good deal and maybe some people will give it a go. As I get the other Q-40's I have back in production, I'm going to offer Starter Kits for them also.
