AR7100R sensor double pulsing

[Geegar]

HI,

I've just finished building my Trex 700 with a YS 91 SR. I have installed a AR 7100R (rev limiter). The problem is when I turn the engine over, I seem to get a double pulse (red light).

Has anybody else got this problem?

Cheers

Matt

Matt,

Is the sensor touching the backing plate? If so try and move the sensor away from the backing plate and see what happens.

I had to do it on my YS91SR motor as well as alot of other people too. I think there's also a service bulletin on Spektrum's website.
