loosing Alot of speed in corners????

[mike stover]

HTB 290

Mac 21 air cooled on k&b lower,hijacker mount

50% nitro

x637 quick in straight, looses some speed in corners, a bit of porposing at full speed

x442 lightning fast in straight, but looses huge amount of speed in corner

Have tried alot of motor heights and angles to see if this prob. would go away.

Anyone have any ideas to try?

Thanks, Mike

Mike,

Try a M-440 with reduced cup and 39 mm in diameter.

Have Fun Testing,

Macs like lots a fuel...and high nitro. You are starving the poor thing on 50%.
