Hi all new here.

Hi hoping this is an easy question have a nitro redcat backdraft 3.5 hadn't been starting in 10+ years. Needed a new spur gear. Got it put back together and running but am now getting a screeching noise. You can hear at beginning of video

Welcome to the asylum, as i always say. As for the screeching noise, gear mesh too tight maybe?

Welcome to the site.

I would look at the slipper clutch if it has one. Check the spring, and clutch pads.

If that not it, check the bearings in the motor clutch, spur bearing or bushing, and then the tranny gears and bearings.
