World Models Mustang

The World Models Mustang is a great electric conversion. It is a very forgiving plane but has excellent aerobatic performance. It's beautiful in the air and a real crowd pleaser. This electric conversion uses the same power system as the Zen 50 (see However, there's a bit more work required to mount and access the batteries.

Hacker Brushless Motors : Hacker B50-13L, 3.7:1 gear; APC-E14x10, 16 - 2400 SR Max NiCad cells
Weight with batteries : 7 lbs 9 oz
Static Thrust : 110 oz
Current : 45 amps
Flight Time : Full Aerobatic 4 min

I have found the Hacker motor system to be the most efficient, high performance system for this class of plane. This package can be used on any 40 size glow powered sport/aerobatic plane. I have used the same power system for World Models Zen 50.

Required Parts:

1. Hacker B50-13L, 3.7:1 gearbox
2. Hacker/Jeti - Master 70 series speed control (no BEC).
3. Aeromodel B50 motor mount with flat front
4. Graupner 60mm spinner with 6mm motor shaft adapter
5. APC-E 14x10 electric prop
6. 2 - 8 cell packs of SR MAX 2400 NiCad batteries arranged in a "shot gun" 2 rows by 4 cells end to end.


1. Connectors: AstroFlight Zero Loss or Sermos or any other high amp connector
2. Thick Velcro
3. Small wood screws

Optional Parts:

Hitech HS-85MG servos - provides same torque as standard size servos but are more, than an ounce lighter. With 4 servos, the weight savings is around 5 oz. That is basically the same weight as 2 sub-C size batteries.


Assemble the plane as per instructions except for the motor installation.
Optional - Consider using the smaller, lighter HS-85 servo

Motor Installation:

To position the motor mounts in the correct location relative to the cowl, you will need to move the bottom 2 mounting holes. Assemble the motor mount. Mount the upper holes and reference the bottom hole locations on the mounting bracket to determine the new hole locations. Push out the blind nuts in the original bottom holes by screwing in the mounting bolt and tapping it with a hammer. They will come out easily. Drill the new holes and mount the blind nuts by using the mount bolt. Tighten the bolt until the blind nut is firmly seated into the firewall.
