Default Electric Cox PT-19 Conversion

Would it be a feasable project to electrify an old Cox PT-19 to say Speed 400 power?

Conversions of older planes is a common occurance these days and times and with the availability of half A engines (or at least the better ones) on a decline, e-power is becoming even more attractive as a power source than ever before. If that is possible.

While the old Cox PT-19 was one of the better plastic offerings as to flyability, its performance was never stellar. True, it was the plane many a newbie cut his teeth on when it came to powered flight and was very popular for a long time.

I say it could be done but I think the best way to go would be a brushless motor for better efficiancy. The standard 400 brushed can motor is pretty heavy and can draw some high amps.

Also if you want to do more than just taxi, I think you would have to go with LiPo batteries. Not sure how heavy a Nicad or NiHm pack would weigh to deliver the amps needed.

Hmmm. some quick looking around I came up with this:

Weighs one ounce and will put out up to 18 ounces of thrust. Far more thrust than needed but you would have to use a large prop to do so. You can use a 7.0 6.0 prop and get less thrus but probably still more than enough to get her off the ground. Only two dollars shipping from this dealer!

I suspect those old Cox P-19's would fly well on an .07 and longer lines. An outrunner would be an opportunity to do that, use 1/2 wires instead of string, an outrunner, and clip the batteries to your belt to keep it light. It would be intresting.
