Rust

[Pit bull kinda guy]

ok my Ofna ultra lx one came in a few weeks ago took off the motor and everything is rusted I don't want to break it down so is there anything I can soak it in to eat away the rust without messing up the plastic parts

Try soaking the motor parts in some old fuel.

If you bought it new, then send. It back!
If not, and if only surface rust, then leave to soak in old fuel, or soak in a cleaner like gt85 which will stop it rusting again. On non sensitive parts, you can use a soft metal brush or steel wool to scratch off more stubborn bits
