Cougar Electric Conversion
Cougar Electric Conversion

Motor: DualSky PRM 40 Brushless outrunner motor

Battery: JP EnErG Pro 3200MA 5 cell 20C Lipo

ESC: 60A Castle Creations

Prop: 13x4 APC 3D electric

This is a great converstion of an I/C 3 D model and with over 1100 watts of power available, it will easily out perform the I/C equivalent.

This was a simple conversion and using a quality power train provides exhilerating performance.

We have also converted this model using one of our 25 set ups with a 3 cell lipo and it makes a really good sport model.

This would make a good starting point for an introduction to electric power conversions.

With both of these set ups, no extra weight needs to be added to the model to obtain the C/G.

In both of these conversions, a separate receiver battery is fitted as the ESC will not power ther servos in a model of this type. We also prefer to use 6V on the receiver for faster servo response.

If you do not want to run a separate receiver battery, then a 3A BEC needs to be fitted.

DPR Graph showing a typical flight of the Cougar conversion.

Unfortunately screen grabs of these graphs are not the best quality, however you will see that the:

Max current was 63.24Amps.

The average current for the flight was 7.23Amps.

The minimum voltage was 17.66Volts.

The Max power was 1124.84 Watts.

All these figures are well within the capabilities of the powertrain used in this model.

Model-pro Ltd carry out a lot of in-flight testing of models to establish the correct equipment for our customers to use.
