10cc like brushless motor - help

[xMeox]

Hi, Im searching a brushless motor for a 3kg (incl. batteries) plane. Normally it would run with a 8,5 or 10cc gas motor. Though on most fields around here gas motors are banned so I want to go electrical. I have no clue which kind of motor I should go for, or even for what kind of motor I should search for.
Any advice?
If possible, a motor from hobbyking (or any other european seller) would be great.
Thanks in advice,
xMeox

a 10cc is roughly equivalent to a 0.60 size 2-stroke nitro motor. Electric equivalents are usually measured by their nitro counterparts. This translates to roughly a 300-500Kv motor, depending on how you prop it.

Well hobbyking lists a 0.60 equivalent in several kv ratings.
Look for Turnigy easymatch motor section.

xMeox,

In addition to the named motors . . . Two rules of thumb that you can use:


100-200 W/# (for 3kg -> 6.6#, that's between 660W to 1320W)

or

2000 W/cin displacement (for 10cc -> 0.61cin, that's 1220W)


In this case, it's nice they tend to agree with each other. You're looking at around 1kW motor, with 1200W probably around the sweet spot. Yes, those tend to come in at the 300-500kv range, but not all motors with that kV can generate that much power. You're also looking at 30-60A on a 6S battery pack (55A for 1200W) WOT to generate those kinds of power.

Wow awesome responses! Thanks everyone! That helps a lot!

Glad to be of assistance!

Here is a thread where I had shared what I did to convert a Fuel plane into electric, might give you some ideas on your conversion.

Good idea Viper...
P6-E Hawk conversion

AT-6 Texan conversion

And maybe not AS helpful P-47 Razorback
