Hi all !!!!
I want to share with you my patriot , i building 3 years ago .
The max. speed was clocked at 170 mph whit radar gun but , is no at made level flight , is whit nose down and full trhotle at 45ยบ approximately.
engine ....... rossi 53
exhaust ..... tuned pipe 7.5 cc Mac
plug........... R5 o.s.
fuel............ Power Master 10%
prop........... 10x8 APC
RPM........... 15,550
Some one know , if the pipe 7.5 cc y too short for this engine ??? there is much difference between 7.5 cc and 8.5 cc ??? I'm use this because i have a ultra sport whit a ys 45 whit the same pipe
