Default electro skaler help

hi guys,

i have just begun to assemble my Graupner Heim Electro Skaler mechanics. it has a Compact outrunner motor that is rated at 385 kV. it comes with two different pinion gears. at 28 tooth and 32 tooth. there is a secondary gear drive so the gear ratios work out to 7.5 to 1 and 6.75 to 1 respectfully.

my problem is this: on a 10 S setup the calculated headspeeds will be in the 2200 rpm range. WAY TOO HIGH for scale flying.

my question is this : how do i get around this ? do i use the throttle curve to slow the head down ? i think this will cause overheating issues as brushless motors are designed to run at near 100%.

please shed some light.

thanks, darren

get a smaller pinion... it will reduce head speed. What blade lenght are you running and how much is the whole model weight?
