Default Pipe lengths

Hi folks,

Anyone got info handy on pipe lengths for 2.5cc engines?

I'm planning to bench run my OPS speed .15 this weekend, it's a FISE config. Has a header and I have an 1110 pipe, aka "nitro" pipe. I'd like to know numbers in the 20k to high 20's range.

Thanks,

MJD

Greetings MJD,

If you don't get a response here, you may like to try the C/L speed forum (maybe you know about it?) on http://forums.delphiforums.com/flyfast/startwhere a good number of F2A flyers lurk and would help i'm sure.

Good uck!

MJD, I would not take anybody's word about what length to hack away from. A C/L guy is operating a plane with more prop and less plane than what you would think is possible for RC.
Just go through the steps outlined by Macs with your intended prop and you'll get results within the hour.

Yeah, I'm sure you're right CP - I just wanted to get close off the mark. Dangit boy, just get out there and run the thing.. when the rain quits.
