Just FYI the propeller mod DIY cost about $5 Also you need to lower the voltage so the motor RPM's slow down.

Just do a search online for 7mm x 16mm Magnetic Micro Coreless Motors. It is a DC 3.7V and you just drop the voltage down a bit to slow it down. The entire DIY motor for this mod should cost you about $5.50 so that douche bag on ebay selling this mod for $100 can eat it.

*again this is about the motor mod not the alternate plane

I have seen the motors cheaper than this, just google it. ebay.com link: DC 3 7V 7mm x 16mm Magnetic Micro Coreless Motor Propeller 48000RPM

VERY simple mod, pull the plastic disk on your plane. Hot glue the motor inside the plan and then just attach it to the connector that powers the flashers for the ramp so the motor will power at the same time. I cant remember which transistor I used, but you just want to drop the voltage so you can see the blades move rather than a powerful 48k RPM. In the end,.. You got a great mod for around $5.

If you search pinside you will find that pinsiders have been doing this DIY mod for a few years now. DO NOT pay $100 for a $3-5 mod.
