I went out yesterday and flew my 500 series kits with good results.
Spitfire- Took a lot of clay in the nose with mild down thrust. Flew stable 35 seconds.
Wildcat- This kit was a complete mod from the kit. Did not use the kit wood and built light. Flew really well 50 seconds.
TBF Avenger- Great flier little clay in the nose- just over 40 sec.
Rufe- Well I gave it a shot and it did ok. The prop is too small- 20 plus seconds.
Focke Wulf- Little clay in the nose flew over 30 seconds.
P40- Very little weight in the nose- 40 seconds.
Damage report- Very little. Puncture under the wing on Wildcat. Some minor details came off on some of the models during landing.
