Default KOLM ENGINES EZ 67 fourstroke Gas

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

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!

Thanks,

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?

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