ok well i figured out the temp on the engine for anyone who has this same question... it is between 190 and 260 although 260 is supposedly running hot for the sh .18 3.0 cc engine...thats str8 from redcat ... anything under 190 is considered very dangerous for engines as underheating is worse then over heating...keep it under 260 since over heating is a problem as well but from my understanding underheating is worse...so keep it above 190 and max 260...just got my MIP on-board heat sensor...things tiny and sleek and easy to use in case anyone is curious about them... nice to have very easy to install and works great...19.03 off ebay shipping included shipped here in 3 days alltogether from order date to door step...any questions e-mail [email protected]
