    RCM Crusader 2 electric conversion

    Hi,

    I have been building a Crusader 2 short kit from laser design services and I am now ready to think about powering. I have come to the conclusion that going electric will be the best way to go. The problem is that it is a pusher with twin vertical stabilizers so I can go no bigger than an 11 inch prop(I have to clip 1/4 inch off the prop).

    I do not know much about electric motor power so bear with me. The only the motor that I have found that would seem to supply enough power and be able to spin a small diameter prop is the Great Planes Rimfire .46.

    My question is, will this motor perform as advertised and swing a 10 or 11 inch diameter prop and deliver the performance of a .46 glow? Also how many cell battery do I need to use for this application?

    I will upload a picture of it later, this computer is not allowing me to do this for some reason.

    When this one comes back in stock. I run a 12x6 prop on 5s and it has more power than a .46 glow engine.

    Love that plane. I was thinking of building it as a high speed FPV plane.

    Sweet thanks for the tip Buzz, that is half the price of the great planes and seeing as this is my first foray into electrics its going to be expensive what with a charger and batteries etc. Hopefully get it flying this year. I am hoping to get some stick time on my javelin before I put the Crusader up.

    You will "NEED" a watt meter. It will save you a lot of money and to help keep the magic smoke in the wires.

    I have (4) of these chargers

    I use old laptop power cords to power them on the bench.

    I have some of these batteries in different sizes. They work very well.
