I want to convert my Nexstar!
 
Hello, I am not a builder and have never done one of these conversions to electric. I like glow but the fuel just keeps getting higher and higher and electric is just so easy. Is this plane easy to convert to electric? I searched the threads and found a couple ideas but they are a few years old and electric and parts have really changed in the last few years. Any help from someone who has done this would be great help.

Thanks!

Here is an old article about converting a similar size trainer to electric. It is a bit dated using NIMH batteries and an inrunner motor but you can still glean some good info from it. Probably the most troublesome thing will be locating the battery pack. Unless you create a battery hatch you may have to remove the wing every time you want to make a battery change.

HeadsUpRC carries most of the stuff that you might need. They offer $2 flat rate shipping and ship quickly. Check with the folks at Heads Up (HURC) for recommendations regarding motor, esc and batteries.

Hey thanks,

these other builds are so old and parts have been replaced and I am clueless as this stuff.

This motor looks good to me: http://www.headsuprc.com/servlet/the...ort/Categories

or this one? http://www.headsuprc.com/servlet/the...ort/Categories


The motor comes with a mount, do I just screw it to the firewall? What about offset?

Thinking about a 70amp ESC but don't know which one???? Hobby King?

5S lipo about 5000mAh's?

Spektrum RX

Cowl from the Nexstar EP and change the blue stripe to red.

What else?

This one might work as well if you aren't looking for 3d power and it is on sale for $24.95. Take a look at the Sport 60 esc recommended by HURC which has a switchmode BEC. Just bolt the motor to the firewall with the supplied X mount. Use washers or spacers under the mount to provide the proper down and right thrust.

If the plane is a tricycle landing gear which the nexstar is I believe you have to be careful with prop size. Those 46 size brushless motors swing 12 to 14 inch props and might not work for ground clearance. I have done a few glow to electric conversions on .40-.60 size glow planes. I've run the turnigy G46 brushless out runner 670kv on two planes. One is running a 12x8 prop 70amp sbec and a 4s battery. And the other is the same motor and speed controller but running a 15x8 wood electric prop on 6s batt. Both are tail draggers and ground clearance is not an issue. Make sure you can obtain the thrust you need to fly the plane with the right prop size for clearance.

Yep, it is tricycle gear. Thanks for the heads up!

Just for grins I just test fitted a motor I bought for my Goldberg Eagle 2 trike with a 13 X 6.5 prop and if mounted on the same thrust line as the glow motor I got 1" of ground clearance. If I move the "X" mount to the top of the bulkhead I get 2" of clearance. So, be sure to check you clearance but it should be doable. Also. depending on the length of the electric motor you may need to either install a new mount bulkhead or use some mount stand offs or a longer mount to get the prop past the aircraft nose.
