Nitro to Electric conversion chart


Hello , I have been trying to find out what size motor is equal to a .40 nitro motor ... I have seen some planes that suggest this for the motor .. I like the plane but not the nitro motor idea .. Can someone please give me an idea what the equal would be ??? Thank You , Don J.

Go to Maxxprod.com for Himax motors and the Eflite site for their motors.. They show the equivalent motors from glow to electric.

OK call me a dummy ... I can't find the eflite part of that web site or any other way to convert nitro motor size to electric motor equal ... I am trying to find out how big a motor I need to equal a .40 or .040 ? I think the equal electric is quite big .. Thanks , Don

Great stuff Adam. Here's another cheap but very good 46 size motor. I put a Twist 150 together for a buddy with the same brand, Turnigy 2000 watt. Works great.

2000watts is way more power than a 46
but thats the great thing about E-power you can get way more power at not much more weight as a glow setup. a TT .46, or typical OS 46 is only about 900 watts max

Yeah, This Twist 150 takes equivalent to a 30 cc gas motor. About 2.5 hp.

For a quick and dirty comparison...

Multiply the dispalcement by 2000 and that is about how many watts you will want for more than decent performance.

.40 x 2 = .8

.8x1000 = 800 watts

800 watts is right between 4s and 5s lipo battery territory.

By those numbers a .049 motor is about...

90 watts - easily done with 3s and still "do-able" on 2s

I would second what JimNM said, with one small addition. I use a slightly different version of the formula that is easier to use, and you can do it in your head. I call it the "Double it and add a zero formula", and here is how it works.

If you have a .40 size motor, most people actually call it a 40 motor, without the decimal point. So to get the watt equivilent, you "Double It" taking the 40 to 80, and then "Add a Zero" taking 80 to 800, or 800 watts.

For a 60 motor you would double it to 120, then add a zero to get 1200 watts.

For a 90 motor, double it to 180, add a zero to get 1800 watts and so on!

Works like a charm!
