I know this lil motor was off the charts on heat. I recorded a peak of 465F on the first flight where I had a temp sensor (chinese special)probe under the spark plug. It lasted that one and only flight because it got cooked. I then manufactured another temp sensor out of some Alumel/Chromel pins (I work in aviation) that I acquired....That held up for 3 flights before it cooked them too.....I saw 509F b4 it cooked that homemade sensor. Now we ran this motor quite rich mind you. So the heat was In my opinion, was mostly due to build up under that stupid cooling/overheating shroud....that you can clearly see they decided to do away with. I was on my third thermocouple adaptation when the motor quit. I had purchased a spare thermocouple from Fluke to use in my Model 16 Fluke Multimeter that I fastened to the risers. I was done using the rinky dink all in one tiny tach/hourmeter/temp gauge....I was going big. Fluke meter big. Well I only got one flight with the fluke meter set up and was going for a second flight where I was gonna finally get some good readings where I could watch the meter (constantly) and not have to worry about flying into anything (Cameron)...Then the motor ate itself. So no readings more than what I had previously recorded and already knew. No further info, per se. But yeah, this motor was a hot lil some bitch from what I gathered trapped under all that Carbonfiber....

Ok, thanks for chiming in, do ya know what change was made? I'm on (EOS Engine) FB page and in a PM they said it was an "Ignition timing curve difference " That sounds more elaborate than a simple timing adjustment by a slotted advancement on a stator plate....That sounds like a New part to me. Just wondering. DD

Another update: We are getting new piston/jug upgrade kit to modify this engine up to a 2019 version ICI motor. Not sure what changed about the coil but they are sending us a new one as well to install included in the kit. I've asked for more details on the coil but if anyone knows please chime in. I'm guessing it may incorporate a Capacitor Discharge type ignition like on my jetskis. No word on the reeds yet either. Here's a link to the mod.... https://drive.google.com/file/d/1I-hVVxdXqFyWwbJa3nU7L0cirTNZUenH/view?usp=sharing

I do know I've worked on several 2 strokes, from jetskis by kawasaki to dirtbikes to chainsaws and weedeaters, and I've never once saw a reed petal that had a stainless steel stiffener reinforcement plate behind a reed valve to sit there and flutter and eventually snap off due to metal fatigue and go through the motor. If they don't have a fix for us, you can be sure that's the first thing I''m removing from the reed cage when we go back together with it. Stupid stupid stupid design. Absolutely stupid and not needed. If it needs a backing that bad just install some Carbon Boyesen reeds and be done with it.

No I do not. Sorry. I'm the only one in my area who owns one.

Update: EOS has agreed to honor the warranty. We will either get repair parts for a fresh topend or hopefully a new motor. The ingested reed petal stop caused extensive damage to the head, cylinder and piston. Hopefully they have a fix for the reeds, on the newer models. This was a 2018 Manufacture, unboxed in April.

You betcha

That was after 40hrs. You can guess what happened next....

Anyone ever have this happen?? https://drive.google.com/file/d/12vwcWfC_CXwwVlA08uw0rvYHCmVAS-jQ/view?usp=sharing

I just took ownership of mine. I've got 6 flights on it now. 6 of my first ever solos even. I love it! It has enough power and then some, I'm 180 pounds. I'm turning about 8000 rpms full throttle. It's still quite rich as evidenced by the plug readings and carbon on the piston head via borescope inspection. But that was also 32:1 breakin oil mix ratio, and we are now just going to 50:1 so that was first 6 hours, I just installed a new fresh plug and we'll get more readings on it after another 6 hours. I'll try to post pics. Btw, if anyone knows proper plug gap for this engine please chime in. I currently have it set to .032 and it seems to like that. DD out.

Confirmation via Email today, The Maverick can be purchased from Parajet with the EOS 150 right now!

I have my instructor looking into getting this motor for me. I think I would like to have it mounted on a carbon scout. Any inputs on this, pros, cons?... all ideas welcome. Thanks!! DD
