ok lets talk 26cc power. take zenoah g26pum case and add 12mm wide bearing to the front where the seal was on the marine motors which use only one bearing in front. its the same case for the plane motors which use 2-8mm bearings. machine hub 4 mm for 12mm bearing clearance and extra support. zenoah chung yang full circle stuffed crank for 26cc boats. red coil with fulley hand ported 26puh heli cylinder on .012 copper base gasket. zero drag seal in rear and boost bottle for cars. g26 marine piston with .8mm ring. walbro ported 257 carb. the outward appearance of the motor is stock except for the coil. the last on took 19hrs of sanding, grinding ,polishing but turned a 15x8 k prop at 16,400 rpm reliably. this motor was lost in crashbut working on a new one with g 270 car cylinder which has better ports and will use 29cc stroker crank. will out perform any 26 by a wide margin if you know how to do it. theres nothing more workable then a zenoah
Hmmm...
11 hp at 16400 from a 26cc engine (thats 420 horses per liter) still looks like a standard typical airplane engine to me, allowable on all airfields, albeit a bit expensive when done.
who said it has 11hp if you cant believe it then dont-who cares. i had a gms 120 with a pitts that turned the same prop 16,000. it must have 10 hp right. my post is for intelligent people. as far as snip -do you know how to modify engines,or just look down on those who do.
If you know power, you also know the limits of a normal aspirated two stroke engine.
An excellent racing engine with a whole team of tecnicians behind it will produce about 20+ HP per liter per 1000 rpm. To boast more is dreaming or bragging.
Normally, when you increase rpm, torque suffers as you go up the rpm range. There is no IF about it. The zenoah 26cc would have to turn 20000 rpm to get 420 hp per liter. This is the math all engines follow.
