Default KOLM 50 cc Gas Fourstroke in 11Kg Zero fromCmpro Zeroo

KOLM 50 cc Gas Fourstroke in 11Kg Zero from Cmpro

Thats a power house and cool sound, i'll give information after a few fuel tanks more,

this Zero is my engine test platform, has been repaired serveral times and has now 11Kg fly-weight, so i can say this engine is running good if you see how it is going vertical with this weight.

seems to have good power.

Are you using a muffler on the engine ?

No muffler, but for the fourstroke it is easy to make one by yourself and you need little space for it

so the same Kolm 50 sounds with muffler, Tiger Moth, very smooth, 12 Kgs 23x8 Prop

Thanks
What size prop is on the Zero ?
Do you know when the 65cc version will come out ?
will the price be around the same as the 50cc ?

I think the 65cc would compare well powerwise to the 50-55cc 2 strokes, dont you think ?

for Kolm 50: Prop sizes: 20x12 or 21 10 or 22 10 or 23 8

with the 50cc there are made the 2 (100cc) and 3 Cyl (150 cc)inlines and 100cc Boxers

with the 67cc are also made the 2 and 3 Cyl inlines and the 135cc Boxers

Kolm ENGINES with its fourstroke inline and boxer gas engines closes the gap to the RCS radials in the gas fourstroke range;

just look here: http://www.vogelsang-aeroscale.com/


there also exists a 50cc RCS Engine, but performance is lower and maintenance is high because of the open vents, such an Engine is mostly mounted with head down into the plane, whole dirt collects into the open vents....

Sounds great! Careful with the machine gun; you'll have to buy those sheep from that farmer

this 3D PDF is pretty cool.
if you choose tranparrent, you can see all the screws, bearings and stuff inside the engine

Hi captinjohn, vogelsang, thats just an example, troybuilt has also the RCS engines on his site, i ment that Kolm Engines fills the gap of inline gas fourstrokes (besides his singles and boxers), Rcs has the radials in that class.

LOL, my bad. I looked again, and now I see a horse in the middle, so they're a little big for sheep! White cows with dark heads (at least thats what it looked like) confused me []

Hello Again, the power increased KOLM 50 V3 has been flown now 2012 and 2013 mostly full trottle by me in my CMPRO ZERO with now 11,5 Kgs and so i can tell you this is a very powerful and solid engine with grooving sound.
specified Exaust Systems will soon be available for the whole KOLM ENGINES program in attachment there is a pdf catalog for the single cylinder program of KOLM ENGINES
