On a calm Chicago day (rare!) I re-maiden my SkyAngel T-45 50mm EDF jet. I was flying at 70-75% throttle to trim it to level flight.
Specs on my T-45 are:
-6-bladed fan (static balanced)
-3S 1000mah 30C Sky Lipo
The last landing cartwheeled the jet, and bent the right horizontal stabilizer, ending my T-45 flights for the day. Luckily I had my light-build Stryker with me. =)
