Default New to me Profi engine

I just got this for a good price. I measured it and its a 21 3.5cc. it looks to be tuned to run over 30,000 but I can not find any info on it. Do any of you Profi experts know anything about this engine?

I didnt even know it was in the pic i thought it was out of the frame. i have two of those little 15's. one is a K&B/Cox and the one in pic is the RJL version. both have steel pistons though..

i have a plane in mind ecoli........ i need to source a header, pipe and a bunch of those glowbee plugs. i did find something where it turned a 6.4x6.6 Bolly prop at 27,800.

I think this is the engine that has the record also buy its still hard to find any info on this or other 21 size pylon engines

airraptor- Its a work of art indeed and I would love to know how many hours went into the CNC programming! I got one about 2 years ago for C/L .21 Sport Speed and Proto Speed. Mine is timed for a mini-pipe and came with one. Yours possibly too? I will check but I believe it is set upfor max power at 32k RPM. I believe the NovaRossi header and pipe will fit. (Planethobby.com have stock). It takes the Nelson plug, obtainable from merlinglowplugs.biz, who stock several types including 4 of the flat coil glowbee that you mentioned.

Good luck and please keep us up to date!

I will smoke it may be a bit though as i have to get a header, pipe and a good prop. i might try a APC 6.5x6 plyon prop but i have blown the tips off them before on some 15's lol

i have could use some of the APC carbon 40 ylon props and just cut them down. till i find the right props

Nice looking engine. Since you're going to be waiting on pipe and header anyway, you may want to look at Steve Wilk's line of carbon props: http://eliminatorprops.com/store/ind...=index&cPath=1
I think he has a few well suited for you that won't blow the tips off.
