drawing too many amps?
I purchased a Model Tech Mini Mach Racer, the motor, prop, and esc called for in the instructions. A KMS 2208/09 motor, a 18amp esc (a Castle instead of the KMS), and an APC 6X4 prop. According to the info sheet that came with the motor it should draw 12 amps cont and 16amps for 60 secs.When I set it up with my watt meter it would draw 18.9 amps. So I tried a KMS 2212/09 and an 7X5 prop and it draws 16amps which is within specs of the manufactures.
The plane flies ok with the 2212 but with the 2208 it flies like a bat out of he!!. I decided to try the 2208 with a Castle 36 amp esc because I didn't want to fry my esc. when put on the watt meter it now says its drawing 21 amps. Both props on both motors are below KMS suggested size.
So my questions are:
1. Will my 2208 burn up drawing the 21 amps?
2. How do you know what size prop an esc to use when the manufactures info is BS?
