Hello because of the great interest and many questions i'll open here a Kolm EZ67cc gas fourstroke thread.

Engine has 67 cc and has very much torque, idle rpm 850 to 900 (its a big single cylinder....) and very low vibrations, accurate responsibility;

Props dimensions and rpm:

24x10 3-Blade Mejzlik 5500 rpm
22x10 3-Blade Mejzlik 6000
24x10 2-Blade Mejzlik 6300
26x8 2- Blade Meejzlik 5700
27x12 2 Blade Engel 5350 !!! rpm

Prop dimensions with rpm show you the very high torque;

Cool Engine, will be placed in Focke Wulf Dora, coming soon.

yesterday i made a short video of EZ67: http://www.youtube.com/watch?v=0g_Azjfc3mA

Dimensions: look at the pdf

Nice greetings from Austria

Martin,

Thank you for posting the drawing that really helped me out. This is what it would look like in a 1/5 scale P51B. I have been waiting for sometime now on a 50cc+ larger 4 stroke single. It really looks promising and the smoothness of the motor is amazing!

So is the motor available now? What is the warranty on the motor?

Thanks,

Vic

That videographer had some pretty closeup views of the Ghost on a couple of those passes! Thanks for the vids The 135 twin sounds good, but the triple in the Ghost is still my favorite all time sounding model! What prop/fuel do they run on the 200?

Flugmax

Hello, prop is a 32x14 SEP prop, http://shop.strato.de/epages/1536673...ftschrauben%22

fuel is called ASPEN, its a special Kind of Gas mixture for 2Strokes, but all the KOLM ENGINES are also runnig with normal 2Stroke Gas/Oil 1:50 mixture

TimBle

Price on the 50?

Mikola

how many engines have you already sold ?
how many questions in this thread ? LOL
if you drop the price of your "inexpensive" engines people will buy them did you notice that ?
good luck with your videos but I think you don't help too much the wallet of your customers.
