Default RE: Cheap SU-27 pusher Conversion to Brushless

Holy Cow...It flew AWSOME!!!! The Himax 2025-5300 just screems. I threw it at nearly full throttle into the wind and it just screamed almost out of sight without a single wobble. I had to get some serious altitude so I could trim it. Once trimmed, it was a serious thrill. I didn't go full throttle because it got small REAL FAST and looked pretty awsome. I took it on a dive at 1/2 throttle and pulled up to see how it took some serious G's. It looked like the wings flexed so I landed her by cutting the throttle. Man, did it glide smoothly. I was pumped. After and inspection of the wings, it turned out that the wings took the G's just fine so I decided to launch again even though the wind picked up but like an idiot, I launched it across the wind so there was a SERIOUS crosswind. It started out ok but a gust caught it and swung the wing causing it to roll upside down. I was in the process of pulling up so as it rolled, it went down and crashed straight onto its nose....CRASH!! I broke the soft nose piece off and broke it again at the canopy resulting in three pieces. When I got home, I epoxied the nose back on, patched up the gaps with a mix of apoxy and foam, and epoxied the repaired piece onto the fuse. A little paint and it'll be good to go.

Lessons learned:
5 minute Epoxy is my friend
NEVER launch into a crosswind no matter how excited you are
Himax 2025-5300 + 11.1v 910mAh lipo + CC25 + 3x3 DD prop is an AWSOME combo for a 9-15 oz. pusher jet (VERY FAST)

I may buy another fuse for a spare because although short, the first flight was impressive.
