| I´m one of these 26cc user. To be righ I own a G230RC and after a incredible problem with I it toke the the decision to change the piston and cylinder to the 26cc upgrading.
A) Zenoah Japan tolds me they will never apply any warranty over a G230RC engine used to power any Heli because it´s designed to be used in Rc car (that´s the reason of the RC sign).
B) Most of the biggest RC Heli manufacturers use this engine to power his Helis and if you look at the latest VARIO brochure they added the 26cc upgrading on it.¿¿?? The apply his own guarantee over them.
Same with some Zenoah europ dealers.
C) The best rpm range for these engines to be used with helis must be close to its max tork point and that means around 10500 rpm. The best power point is around 14000 but imo what zenoah tries to say is that this engine can achieve this power but not to keep it for a long time or it will died shortly. (The 1/5 Rc cars hold only the max rpm for short time periods)
D)The 26cc upgrading will help you to get more power where you need it, close to the max tork point, so you dont need to run higher rpms to achieve the desired power. At 10500 rpm I can´t notice any vibrations difference but a lot of power difference on my camera ship (I can lift the same weigh at 60% thr as I can do with the old engine at full power).
E) About temperature range, I took the reading from one of the holes you can see on a G230RC close to the exhaust at the cylinder base and always from the same place. In winter, after a 3 min hovering I can read 98ºC (having a 10-15ºC weather temp) and now, I can read 107ºC after the same test but at 30-35ºC weather temp. (readings comes from a simple RC car thermometer and not from a Infra red one You must run the engine with the needles as open as you can to allow the fuel help refreshing the engine but the fan makes a brilliant job.
My heli weighs 20lbs without fuel and that must have any influence in the temp readings increasing it more than normal.
Hope it helps a little
