When mounting motor and speed controller, you want to ensure they have proper cooling. In many cases the cowling already ensures proper airflow over these components, but when I do glow to electric conversions, I often have to be a little creative to get the cooling right.
A ‘cool’ method i often use (pun intended 
) when mounting the 90A Titan controller, is to make a cutout for the cooling fins so it protrudes into the airflow.
The pictures show the controller installation in a Katana 28% and a Ultra Stick 120 I recently converted. Both models will spend most of the time at part throttle, and as this is where the controller get the hottest it makes good sense to ensure optimal cooling – and apart from that, it adds that distinctive ‘Electric power’ look to the model.
