HootMaRoot Posted July 11, 2013 Share Posted July 11, 2013 I am right in thinking that when you up the voltage you are ment to gear lower ? Because I have just had my first proper bash with 6s on same gearing as I used with 4s and the motor is real hot with coolish ESC and fairly hot batteries, so I am lost as I thought **** ESC hot motor was under geared Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted July 11, 2013 Share Posted July 11, 2013 Yes but im guessing your esc has a cooling fan possibly cooling it off quick? You should gear down really, you haven't told us the motor, esc etc. Quote Link to comment Share on other sites More sharing options...
HootMaRoot Posted July 11, 2013 Author Share Posted July 11, 2013 (edited) Tekin RX8 cc 1520 motor geared 20/48 Also its a RC8Te Edited July 11, 2013 by HootMaRoot Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted July 11, 2013 Share Posted July 11, 2013 Kv of the motor? Quote Link to comment Share on other sites More sharing options...
HootMaRoot Posted July 11, 2013 Author Share Posted July 11, 2013 The 1520 only came with one kv 1600 Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted July 11, 2013 Share Posted July 11, 2013 Possibly undergeared then if the esc is running cool, might have to up your C ratings if the lipo's are getting hot. Its a very torquey motor being 1600kv so I reckon it still needs to be upped a few teeth. Quote Link to comment Share on other sites More sharing options...

NuttyProfessor Posted July 11, 2013 Share Posted July 11, 2013 Possibly that too so the heat was lower, needs tall gearing for speed. Quote Link to comment Share on other sites More sharing options...
barnetbasher Posted July 11, 2013 Share Posted July 11, 2013 (edited) if it was undergeared it would have been too hot on 4s.. I run a 1520 motor on 4s 14/46 on my monster (see sig) and it runs a treat.. 6s is a whole new ball game....i'd gear down to 16/18 and do some temp checks .. personally..I'd try gearing up on 4s or 5s, that works a treat on my 8th truggy, if you do end up needing some smaller pinnys ..let me know...you can have them for postage cost (which is about 398 quid at today's rate ) Edited July 11, 2013 by barnetbasher Quote Link to comment Share on other sites More sharing options...

big turbo Posted July 11, 2013 Share Posted July 11, 2013 (edited) You really do need a IR temp gun no good guessing temps :-/ What's the setup in?? What's the spec on lipos?? Mah & C rating?? If they are up to the job and getting hot then you are more than likely over geared on 6s Edited July 11, 2013 by big turbo Quote Link to comment Share on other sites More sharing options...
HootMaRoot Posted May 5, 2014 Author Share Posted May 5, 2014 Well that month turned into almost a year Lipos are 40/50c 5000mah Motor temps now running at 60 degrees C Lipos now @ 40 degrees ESC @ 45 degrees Seems to run a lot cooler when tarmac running compared to grass/gravil/mud might just need to find some tires that grip better or by slightly lighter on the throttle Quote Link to comment Share on other sites More sharing options...
