Has anyone have any advice or good info on this 2 engines?

CERMARK SPE26CC

CRRC Pro GF 26i

thank you!

Ready for a new radio should I go Futaba or Spectrum?

26i runs just fine after one/two hours break in....
We are all useing Futaba with NO problems...

The 26 from Cermark has served me well. I feel the Spectrum is a much better system. Have had over 180 flights on the engine and radio. No problems. I like the programing much better and also a much better choice of receivers.

thank you guys!

How does the Cermark SPE 26CC engine do on vibration. Also is it large and heavy for a 26cc gasser. Can it go into a P-51
1.40 sized plane.

I personally prefer SPE-26 for the 90-120 class. I think the 1.40 is out of the SPE-26's range. You can use a the 40cc version in there, but 26cc is probably not recommended. You can check out some of the airplanes that we intended the SPE26 and SPE-40 for on www.speengines.com url.

Cermark

I baught the extra 260 with the spe26cc from Cermark.The ignition went bad before the maiden flight, secondly they say that motor will hover that plane that's not happening either, I called Cermark and they told me that I should try to use a 15x4 prop then a 17x4 prop.who knows it might be me or my flying buddies but nothing seems to be working, everybody at the flying field is let down. I would like to take the plane fully set up to Cermark and let them show all of us the power this thing really has because none of us can find it.

Same thing at my field. One guy's won't even put out more power than my Saito 100. It turns a 17x6 at like 7,200 or 7,400 on a good day. Almost destroyed his Goldberg Sukhoi. Took up a couple hundred feet to barely lift up off the ground.

I will never recomend this motor to anyone. I to have a saito 100 on my funtana 100 and its seems to be giving me about the same power out put. I was on the Maxford sight last night and the said the spe26cc at 7400 rpm was putting out 12lbs of thrust and I cannot even get 9 lbs of thrust on the best day. The reason I bought the plane is Cermark told me over the phone that the extra 260 with the spe26cc would hover that plane no problem with plenty of pull out power. Its a disapointment for $500.00 I could have just upgraded the motor on my funtana and had money left over.

Thats strange your having problems with the spe 26cc.
I have one in a sukhoi 31 the planes weighs 9.8 pounds and it flys just great.
My 26 is turning 8000 with a 16x8 wood prop. sorry your having problems.

I don't own one, but might be about to own one. The only two I've ever seen run can only turn an 18x6 at 7200RPM. There's nothing wrong with it, it just doesn't put out any power. It turns a 17x6 at 7600.

If I buy it, it'll be from a friend used. It's going on a 60-sized Thunderbolt from h9 if that gives you an idea of the power output.

iv e got one and its a piece of sh1t
bought the extra and 26 combination engine would nt stay running. engine replaced by cml and fitted to model . totally guttles and had a misfire that i thought was rich mixture. model crashed on 4th flight total loss of radio contact. at the time i thought it was a loose crystal. 3 months later engine fitted to world models p47. still misfires but pursevere with trying to set mixture first flight total loss of control so fitted 2.4 spectrum . second flight ok apart from misfire still trying to set up tryed it tonight won t start looks like ignition module has packed up . so its off to lms tomorrow to try and get sorted. i really feel like thowing it in the bin. with be sticking to zenohas in the future have 2 and they re great

I have a SPE 26, and it is WEAK! Go for the CRRC. I haven't run it, but I've seen videos of it, and it is 10,000,000 times more powerful than the SPE. There was a QC problem with the CRRC's, but I think they worked all the kinks out.

My spe 26 turns a Menz 17x6 at 8700 rpm. I had to change the original carburator for other with a bigger venturi.
The original carburator wt-500b is 9.53 mm venturi. You have to replace it for other ranging from 11.1 mm to 13.4 mm. Check the threads on the gas engine forum about this engine.
My spe pulls the edge 26cc (from peakmodel) out of the hover just like a rocket.
Peakmodel sells now an "improved spe 26". Anybody knows which carburator uses ?.

So maybe the power is hidden in there, somewhere, behind a new ignition system and carb, but, uh... $$ not a deal after all that.

I have two flying buddy's... both with identical Funtana 90's.
One has the spe, the other has a 120ax (that I broke-in and installed for him)

I dont know any other way to convey the comparison, so I'll spill it all.

- The spe makes ALOT of noise.
- The spe leaves no hover "head-room", its nearly maxed and slowly climbs out.
- The spe is more complicated.
- The spe was on its second ignition module before seeing air - it was replaced promptly by spe though.
- The spe is heavier.
- The spe is more expensive.
- The spe is clean.
- The 120 is filthy.
- The 120 is quiet.
- The 120 has far better power.
- The 120 drinks more fuel, but it performs well on cheap stuff (10-15%), and flight times were plenty long.
- The 120 fired and ran well on (I kid you not) the very first break-in chicken stick flip after being primed - I was stunned.
- The 120 mounted easily, was simple in all respects, and the muffler turned sideways for a perfect fit. (cool little 90deg adapter included)
- The 120 has yet to dead-stick.
- The spe has had 2 dead-sticks. Unknown cause. Uneventful, clean landings.
- The spe plane is lucky it has the better pilot (by far).

The guy with the spe is well informed and builds/has much larger gassers. His tune is good and his piloting is excellent.
He went with the spe because its cheap and he had the old 90s collecting dust and decided to try the little gasser.
It does fly ok and it is alot of fun, and sometimes the noise is even music to the ears, its just not really a good 3d machine. He is a bit disappointed in it, but not hating it.

All things considered (even fuel), the 120 is the way to go if you want the most power for the $$
The spe is the way to go if you want decent, clean, cheap-fueled power and dont care about hanging on the prop.

gpar, I found BCMA sells a 11.1 venturi Walbro carb and want to swap carbs. Did you enlarge the insulator block opening to match the new larger carb opening?

When I tested the engine with the original carb, I was getting 7500 rpm with a APC 16x8.

Hi Ed,

Before you changing out the carb, does the engine make funny noise (like 2cycle trying to be a 4cycle)? or does your ignition makes a clicking sound?

Steven,

It's been a while since I've run the engine on my test stand, but I don't recall those symptoms. I loaned out my test stand so I can't get to it right away. Once I get my test stand back, I'll try a before and after comparison.

Here is video that we put together with Cermark's new Scale Series 70 with a new MLD-28S engine. The video is a composition of the 1st 3 flight of the airplane with a brand new (not broken-in) MLD28 or 28cc gasoline engine. The video is handheld quality. If you want better quality, then you can submit your video

Here is the link: http://www.youtube.com/watch?v=6OY5o-OzfDo

We'll be at Sepulveday basin this Saturday if you have question on both your SPE engines and airplanes.


Peace,
