~>Thanks guys. I'm launching off a stooge 90% of the time. Yesterday the grass was about 2-1/2" tall, same as my wheels. I picked the driest, thinnest area the wind direction allowed. 3 tries with the Shoestring Stunter, 3 times it nosed over within 10-12'. Only ever had it do that once, when grass was clearly too tall and I tried anyway.
My 45" modified Flying Fool with a 46 (53oz), got up fine (same 2-1/2" tires), but it flipped nose over on landing. This one is the mystery to me. CG, is correct. But this is its third landing on grass, and third nose over. Third time to damage its tail. One oops might be due to a tad high landing speed, but the other 2 were very slow and controlled.
If you look at the flying Fool note the gear. I altered mine just to improve grass field performance. Moved the mounting point one bulkhead aft, then raked it forward 45deg, the result actually placing the axels 1/4" ahead of stock location.
The SS is light and I understand very well how it could hang up and nose over on launch or landing. But this super Flying Fool has me stumped as to its inability to remain upright when landing in grass.
Just measured and gear is fully 6" ahead of the CG.
