Here's my 2 cents
The tiny trainer was the first plane I build and maidened. A couple of things I would note that are salient to your situation:
1. With a 10kts wind, the tiny trainer is going to be a bear to fly. It will fly with some considerable effort, but it won't be fun. The difference between calm and 5 - 7 mph is night and day. The I almost gave up after I maidened my first tiny trainer because there was about a 7mph wind and no matter what I did the thing would not fly right. Took it back out one evening when it was calm, everything still trimmed just the same and it flew like a dream. So maybe you need a heavier plane...FT Explorer perhaps.
2. When I launch my tiny trainer, I do so a full throttle. It does make it climb "aggressively", almost to the point of stall but don't let that bother you, just force the nose over with some elevator and then power back to about 1/3 - 1/2 throttle. As soon as you pull the power back it will fly much better.
3. My third Tiny Trainer had a problem with the wing. It was hard to tell visually, but one side had a bit more dihedral and a slight twist that gave the end a higher angle of attack. No matter what I did, it always banked hard to one said and required full rudder input to fly straight. Eventually I realized I could move the entire wing over about 2 inches to compensate but that gave it some other strange flight characteristics that were not very good. I rebuilt the wing and it flew like a dream.
TLDR: I think in 10kts. you're going to struggle even with a perfectly trimmed plane.
