Scozwinker Posted August 10, 2011 Share Posted August 10, 2011 My Losi XXL was telling me it was overheating on the first break in. It was reading between 125 to 140. Is this too hot because i have heard some people have issues with the telementary on the XXL and I did the water test and it seems about right , maybe a little hot.. Could it be there is little air flow (even though the top is off) as it is going in slow circles? Thanks for any advice. Quote Link to comment Share on other sites More sharing options...
Ruhel Posted August 10, 2011 Share Posted August 10, 2011 (edited) Reading online and on youtube people are are keeping the engine temps below 220f. What break in procedure are you using? Heat cycle or just idling through tanks? This manual has the operating temps explained. Says normal op temp is between 190f to 220fhttp://www.losi.com/...STXXLManual.pdf Edited August 10, 2011 by Ruhel Quote Link to comment Share on other sites More sharing options...
Scozwinker Posted August 10, 2011 Author Share Posted August 10, 2011 I asked my local hobby shop and they said for the first 3 tanks do 25% throttle to 50% on the last tank accelerating up and down slowly... Did my second break in and i was doin 3 second bursts of around 25% and it was almost reaching 150 C :S Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted August 10, 2011 Share Posted August 10, 2011 150c!!!! That's a little over 300F .... which is cooking your motor bigtime. I would get hold of a proper IR thermometer ( they aren't expensive...I got one for Quote Link to comment Share on other sites More sharing options...
Scozwinker Posted August 10, 2011 Author Share Posted August 10, 2011 Cheers nitro, when I did put a drop of water it didn't boil that violently but about the time it should take which is a few seconds i believe... Here is a vid I just took, it was supposedly 180 C... Quote Link to comment Share on other sites More sharing options...

Dan13 Posted August 10, 2011 Share Posted August 10, 2011 it can get as hot as it wants untill it seizes. A good test is to spit on the head and see if it sizzles like the food in inian resturants.lol If it dont evaporate then its fine. Quote Link to comment Share on other sites More sharing options...
my0wnme Posted August 10, 2011 Share Posted August 10, 2011 also temps will be higher as the engine is loosening up..just run it a little richer for for the break in period and when you start driving normal the air can do its job,by that vid,i think its alright and your temp gauge is proberly misleading, Quote Link to comment Share on other sites More sharing options...
RooBoonix Posted August 10, 2011 Share Posted August 10, 2011 (edited) is 120 degrees celcius, or 248 fahrenheit an ok temp?? i may richen up slightly just incase Edited August 10, 2011 by RooBoonix Quote Link to comment Share on other sites More sharing options...
my0wnme Posted August 10, 2011 Share Posted August 10, 2011 id say between 230 and 270 is considered a safe temp to be at,anything above 290/300 is danger Quote Link to comment Share on other sites More sharing options...
lazkopat Posted August 11, 2011 Share Posted August 11, 2011 Ideally say about 220 F to 250 F max. Quote Link to comment Share on other sites More sharing options...
Jonny555 Posted August 11, 2011 Share Posted August 11, 2011 Last Sunday I witnessed a sweepstake to see how long an engine could last at full throttle whilst on it's starter box. It lasted about 2 minutes and reached 266C! Quote Link to comment Share on other sites More sharing options...
Nomsicle Posted August 11, 2011 Share Posted August 11, 2011 I keep my engine at around 240ish F and it runs just fine. Quote Link to comment Share on other sites More sharing options...

rccars1 Posted August 12, 2011 Share Posted August 12, 2011 (edited) I'll never forget when I put my leg on a 125 pit bike engine OUCH! Craig Edited August 12, 2011 by rccars1 Quote Link to comment Share on other sites More sharing options...
R46 Posted August 12, 2011 Share Posted August 12, 2011 you need to be running in without shell on, also you need to put holes in front window to aid cooling of engine. 180c far to high HSN needs riching anti clockwise what fuel using?

Sandy Ravage Posted August 12, 2011 Share Posted August 12, 2011 Since fitting ceramic bearings to my Alpha S852, I'm getting temps of 280-295f and have had no problems. I find the hotter it gets the better it runs. Though I have heard and seen people running their Alphas at 300f with no problems. Some engines like it and some don't...

Scozwinker Posted August 12, 2011 Author Share Posted August 12, 2011 It turns out it was really lean some how? No idea because I can't remember touching it but i richened it quite a bit and now it is hovering around the 100 C mark thanks all Quote Link to comment Share on other sites More sharing options...
