got any video, i would love to hear your motor with that pipe?

RE: 3W-55Xi
 

Got 4 flights on a Menz 24X8 S on the 3W-55Xi with ES55G Composite pipe @ 11" header..

32:1 Stihl Ultra
77*F with low humidity

Pulls this prop 7300 rpm on the ground.. Seemed to clean up the midrange with some added prop load..

Tried a Xoar 23 X 8 Laminate prop ..

Pulls this one 7800rpm on the ground..
Super fast throttle response and rocket out of hover performance.. My favorite so far..

have u tried a CF Xoar 23x8 i hear they rock

RE: 3W-55Xi
 

Everyone tells me that the Laminate loads the engine a little more than the CF version.. That would put me at or over 8000 on the ground.. I will still probably get one to try though...:D

nevermind then :D....i wouldnt want to your to redline your engine..... maybe a 24x10 cf would be good? what RPM range would you be happy with

RE: 3W-55Xi
 

I am happy with the 23X8 Laminate on it.. I do not fly level flight at WOT any times. The only WOT is on vertical lines so I am not worried about the high static rpm.. The engine is very responsive and the pullout from hover is instantaneous.. I do not like the 10" Props on this Pitts Bulldog, they are too fast of a prop airspeed wise... I will probably try a CF 23X8 to see how it does.. I rearely believe anything I am told on the internet...:)

RE: 3W-55Xi
 

you must be an IMAC pilot if you only do WOT on uplines :D. I've been trying to practice throttle management but i find it hard...lol ive already snapped 4 sets of wings in 3 years. thankfully none were gassers

RE: 3W-55Xi
 

You have to remember , this combo at 1/2 throttle is pulling what most 50cc class engines do at WOT!!!![X(]
