KOLM ENGINES EZ 50 V3 Fourstroke
 

Ive got now the power-increased and modified KOLM Engines 50cc gas fourstroke-engine

It turns all my props at least 400 rpms higher than the former version.

The engine is cnc made from massive alu and has very good gas-responsibility and running culture, Cool and powerful fourstroke sound.

because of its torque you can also use very big props in relation to the ccs, for example 23x8 props in 2,7m Tiger-Moth with 12 Kgs

used props and rpms:
MenzS 20x10 3 (thick 3 Blade wood prop) rpm 6000
APC 20x12 6800 rpm
SEP wood prop 21x11 6350 and SEP SCALE woodprop broad blade 20x11 6550 rpm
All the KOLM ENGINES, eg 67cc single, 100 and 135 boxer, 100 and 135cc Inline
are already available with ELECTRIC STARTER :

:DCool: the 100cc and 135cc Inline Twin is now available with 180° or 270° crankshaft design, 270° is like a Vee engine charakteristic and Sound :D

videos will follow soon

here a video from the EZ50 former Version in my zero: http://www.youtube.com/watch?v=n2nxOw9D_pU

KOLM 50V3 Video coming this weekend - here you are : http://www.youtube.com/watch?v=PsXsU...ature=youtu.be

you can design and create the sound from rough and loud to very smooth with small exaust-dampers by yourself, 4strokes need no big dampers;
Nice Greeetings

Hi Flugmax, is there any drawing diagram for size on both the 50cc and 67cc single motor? I need to see how well it fit a 1/5 scale P51

Thanks,

Vic

Hi Martin,

I was hoping for a 65cc drawing showing the mm measurements. I want to profile it on the plans and see the clearance on the cylinder head. The 50cc drawing fits great on 88" P51B but the 65cc power is better. Is the 190 you posted a Sist? I don't see a 50cc flying that bird well as they typically weigh in 27-30lbs but I could be wrong, the 65cc will be perfect.

Here is what I am hoping to put the 65cc into, at the moment I have 3w50i that fit okay, however I am really digging the sound of a 4 stroke.

RE: KOLM ENGINES EZ 50 V3 Fourstroke
 

This is what the Kolm 50cc may look like in the P51B profile. I guess the Kolm 100cc inline twin will fit similar and go 160mph but for a price of course.

RE: KOLM ENGINES EZ 50 V3 Fourstroke
 

Hello Kolm 67 dimensions, well i'll make a new thread now

greetings from Austria

Triumph motorcycles is utilizing the 270* firing order in their large Twins.

It mimics the reciprocating & power pulses of a 90* "V" twin to reduce vibration.
