By the way, stuffing the muffler with steel wool is something we used to do when I rode Dirt Bikes (back in the day). Actually, the pots scourer would be what I'd try first (the stainless steel, not the plastic stuff). That material is coarse enough to limit back pressure but should yield a somewhat quieter muffler. Fine Steel Wool would probably be a little too restrictive. I think I will try the Pots Scourer stuff first and then maybe try very coarse steel wool. Also, based on my experience with steel wool in dirt bike mufflers, you would probably need to replace it more often.

I ran a xoar 17x6 and got 8600 and today after one gallon got 8100 on a apc 17x8, once fully broken in will probably go to a 17x10 carbonfibre mejlik. I might think about putting a walbro 600 or something basically the one thats on the evo 26, because this one is ok... but the transition could be better.

Well, lets just say that we were happy that we had a lathe and a milling machine in our shop !
We spent many of cold nights this past winter, preparing these engines to meet our expectations and to market them in the USA.

They are good engines, but who ever decides to sell them in the US, better check their QC.

If they would have paid more attention to detail their quantity, it would have worked out.

And that's all I have to say about that , Forest !


We are continuing our research within the Chinese market, and "to focus on the
pilots that can not afford a $700 engine" in every large scale plane they own.

P.S. - Thanks to all who have supported us this past year.
For you are the reason we continue moving toward our quest.

I have it on a aeroworks yak 54 1.20 size same as jimeni. It pulls good but the carb issue is that lets say your coming out of a loop when you cut the power back it takes 3 secs to initiate that power change, and every gas engine pretty much uses walbro carbs its just these are the cheap line of carbs. Mine starts like a dream now just 3 flips with choke on and then one or two flips with choke off and it starts right up, in the beginning it sucked at starting pretty much you had to get out the electric starter. I hate apc for 2 reasons there heavy and they bite me, lol their source of nutrition is peoples digits! It was flying good with the 17x6 but needed more speed for IMAC. Plus I fly off of grass so I need the ground clearance of the 17" prop. Its a awesome engine for what I payed for it, shakes like hell on low idle but every single cylinder engine does (and yes my props are balanced). It should be sweet with some carbon fiber!
