So I purchased a used Losi NT and was out for my first run and got tangled in a bush however the throttle stuck and when it came out it hit a tree. Due to the engine over reving I had a hard time shutting it off and the temp reached just over 200. What kind of damage do you think I've created outside of the broken parts that have been ordered already (arms, etc.) Any engine damage? I have a Picco 12

if it just got to 200 then i dont think there should be to much damage... but ive never ran that engine before so i could be wrong

Yea i wouldn't worry too much, you'll know if anythings broken believe me. still if it gets to tht temp id richen up ur high speed needle a bit...

no two hundred is nothing optimal operating temperature is 230

The normal operating range for most small block RC engines is anywhere from 230 to 270 degrees F. Running temps below the minimum target will wear internal parts of the engine faster, as they haven't expanded fully.
They are designed to be run in that range, and expansion is accounted for in that equation. So don't be afraid to lean it out a bit, if you need to.
