.46 convertion
 

Hi folks
I am replacing a OS .46 with a 11x7 prop with a electric motor.
The question is if it were on a test stand what size motor.battery and ESC will i need to get the same performance?
I am guessing I will need 1000 watts roughly.If it iis a help I will be converting a 40 size Kaos ,40 size sportster and sportster bi plane.
I would like to keep it to 4S or 5S battery.
Thank you for all the help.

Personally I'd use 5s if you want the 11x7... 4s would need 13"-14" prop.

My first question is always about weight. How much does the plane weigh, all up, ready to fly today?

Typically for a glow conversion we shoot for about 100 watts/pound. If you are one of these "way to much power Is just about right" then we might shoot for 150 to 200 watts/pound.

But using an electric "40" is a good target for typical pilots.

I find the Electrifly motor selector very helpful.

There are more detailed configuration tools but these are out of the conversion table.
