Hello i am new to the forms but i have a arrma limitless with a spektrum firma 2050kv motor in it and i was looking at the motor and gear after 2 runs and it looks like the motor and gear got welded together and i was wondering if someone had a similar issue with this

You sure that’s not just thread lock?
Looks like it could be just some locktite on the grub screw dripped onto the rod.
it looks like the grub screw is not aligned with the flat (if the flat is at the 7:00 position). Back the grub screw all the way out before trying to get the pinion off. What tools are you using and how are you attempting to separate the pinion from the shaft?
That’s how it’s supposed to be. With the grub screw in there, the gear is supposed to be locked on.
Once the grub screw is loosened, you can then be able to pry the gear off.
From the factory, they put some locktite on grub screw to help keep it tight in there. I think that’s what you’re seeing in photo.

I had a flat head screwdriver but i was not putting a lot of pressure on it because i didnt want to break it and yes the gear is lined up and i have had the screw all the way out as i was trying to get it out
