Kilry 52,
I believe Richard L may be one of those, how did you say it, (looking back at your last reply) Oh, here it is, "Old hard core scale dudes"...LOL. I'm only kidding Richard L, so keep your scale exhaust ports open. I believe the intent of this thread was FLYING with a 4 blade prop. Can you post some photos of your ponies with their 4 blade props. A video would be even more convincing for the scoffers! Good luck.

"Keep 'Em Flying!"
