Title: Props to use B-Team Race ??
Post by: dankar on December 29, 2010, 03:37:06 PM

I plan on using a OS .28F. I also have a plain but good Enya .29. I don't know how small to go and have a few 8/7's. I may have a few old 8/8 someware.

Hi Dan

If you want to go fast....7x7 or 7x8 APC Sport prop. The Apc 7.8x6 or 7.8x7 such as we use on our TQR models will work as well. My B Tr would go 16.3/7 with a GMS .25 on the 7x7 APC Sport Prop.

Give your pilot a break. Start flight testing and trimming using a 7x6 or 8x5 and run it fat! Work up to the full-race configuration. A slightly untrimmed B-TR (and critically--the landing gear trim, too) will eat the pilot's lunch and do severe damage on a takeoff accident. Getting a B-TR trimmed and set up right is harder than most other planes in my experience. Some never are right due to design features that sounded good and looked right (based on general practices, sport planes, stunt planes, etc.) but will not work on a B-TR. I have helped flight test four different planes. Two of them never were capable of being raced. My two cents...
