Twin Tail Motor Mod
As requested a short tutorial on how to mod your tail to use two motors, the advantage for this being the reduced current being forced through the little engines ( especially necessary if you're running 11.1v instead of the 7.2v these babies are designed for).
I of course did this mod on my HoneyBee CP2 helicopter but I'm sure the ideas are the same...
The mod is pretty simple, just requires a bit of patience to get the distance right - too close and you'll put too much strain on the motor, too far and you'll ruin the teeth.
For this you will need:
Tools
- Super glue
- (Sand paper and hacksaw) or dremel
- soldering iron
Equipment
- Old tail mounting
- some scrap wire
- Begin by taking the old tail motor mount, prepare this by removing the
part for the rotor and the connector to the boom using your hacksaw or dremel. Making sure to cut as close as possible to the rotor mounting to give you space to play - Now mount the motor in its new home, we do this now so you can check how close the teeth will be.
- Place the mount in position on top of the rotor mount on your heli, using the sandpaper placed on a flat surface, sand off the base of the mount until the teeth interlocking but not tightly.
- Glue the mount in place, I surrounded mine with araldite for extra strength, I'll let you know if its need :S
Finally solder up the new motor, making sure to solder the side connected to the casing of the first motor the the side connected to the casing of the second motor ( it worked for me but I ran it without the rotor in place to make sure I got it right :) )- Now that you have the extra weight on the tail be sure to adjust you battery to compensate : )
- And of course finish both motors off with a decent heat sink
I didn't notice much difference when flying, expect your trimming to be all wrong, but apart form that it flies the same - just without the heat from the tail motors.
