Hi all

I have an Ansmann Mad Monkey, and getting frustrated by the juddering when pulling away. It seems I need to go sensorless, but what combo?

Looked at the Speed Passion Revention R, but might be over the top for an amature, as I don't need too much adjustment - I'll just get confused!

What are peoples toughts? I do like the look of the Speed Passion range. Preferably deans, with switch and fan. Must have reverse..

Thanks!
