Installing the optional heat sink on a Blade CX

This is another installment in my series on repairing and modding the E-Flite Blade CX micro Helicopter. In this Instructable I well so how to install the optional motor heat sink. The reason for installing the heat sink is to dissipate heat from the motors. This is especially important if you are flying the model numerous times in a row without letting the motors cool down in between, over heating them. This is because the motors are being run for a long period of time due to the LiPo battery having such a large capacity and running the motors at a higher voltage then they were originally designed to run at. This is the problem with using LiPos with brushed motors, I have toasted 2 motors in my old Zagi 400 using LiPos with it.

Step 1: Materials

You well need:

- The optional E-Flite Blade CX/CX2 motor heat sink, the hobby shop you bought the Helicopter from should have these in stock or can order one for you.
- Small Phillips screwdriver, there should be one that came with the Helicopter.
- Something to cut the zip tie with, I used a large toenail clipper, these also work good for clipping leads on components after you have soldered them to a PC Board and for cutting fishing line when attaching hooks.
- A replacement zip tie, again look with the stuff that came with the Helicopter.
- Heat sink compound, I did not use any because I could not find mine but it is recommended to use it.
- About 10 minutes.
