coooool, coooooool lol hhahhahha btw cool engine, i do love these little simple air engines due to there simplicity they stop running at higher pressures am i right? but still not really a prob when ur dealing with 800 psi co2
This looks like a GMOT CO2 engine...similar and possibly made by Gasparin. The RPM's/power output and thus the run time of these little motors is adjusted by rotating the cylinder head. I have a bunch of them...including some twins, and I'll put some video of my free flight stuff (with CO2 powered motors) up pretty soon. Most of mine run for 1-2 minutes. They are great little motors. - BC
You can cover the front hole and leave the rear-facing cylinder hole for some adidtional propulsion.
Cylinder-up mounting is preferred as the small ball that should close the valve in the cylinder falls faster when is assisted by pressure AND gravity.
WD40 is such a good lubrifiant that in a good CO2 motor the propeller should spin freely together with moving piston during unpowered 30km/h free-flight.
Reheat the main gas source to 50 centigrade (electric heat or just with hands up to 36.6C) before recharging for extra poressure. Paint all the motor parts in black for top results (gets heat from the sun during flight, increases pressure, melts CO2 ice deposits inflight).
Something very exotic or older than me. Never seen (I live 200km from former tchech rep.), never heard of. Cannot find on the web. Looks very solid.
From my exerience, if the motor has 0.27cm2 stroke, and if the motor's tank is 16mm diameter, 42mm long, the running time should be around 30-60s on CO2 drink recharge (such recharge cointains 8 grams of gas). This means that paintball tanks has somehow smaller pressure than drink refill?
very short runtime. similar sized tchech Modela or russian CO2 motor with similar propeller runs for 30-60 s depending on RPM from a single recharge (if filled from 'syfon' (Polish) recharge - CO2 pulveriser for drinks). Maybe CO2 pressure is weak or you got a lot of leaks.

I have one too. Won it yesterday as a prize at a model flying competition. mine is GM 120.

dose it need any lubacation?

Light weight sewing machine oil now and then!

RUnning time on one filling is 45-100 sec

you sure it's not just powered by pressure?

same thing you dumb ass

It is powered by pressure, but the working fluid is Co2.

all engines are powered by pressure no matter what the fuel is.

Very similar to an Air Hogs motor.

What is the origin of this motor? The red propeller looks like Modela, but the body is metal!
One more thing, what is the big bottle of compressed CO2?
krbosak 4 years ago
This motor ia Gaspiren-120 (Chekoslavakien)and the bottle is from paint-ball gun.

@mastmar if this actually can be powered by co2 gas then this may be the future but what does it expose?

awesome im very interested in these engines they are so quiet and never a shortage of co2 just gotta compress it
