WADREW Posted June 19, 2013 Share Posted June 19, 2013 I have the Vorza and have blown 2 2650 motors running 6s ( which hpi say is ok to run) So I went back to standard 2200 motor and all was fine until tonight when I took it out for a test run ready for a big bash this Sunday when BOOM it stopped dead again and the motors locked solid. I can't keep buying motors every 2 month aspecially when it shouldn't be doing it as I'm doing nothing wrong. Am I in my rights to contact hpi and demand a new motor and drive shaft as it snapped that too as it ground to a holt?? Had enough now and might just sell it and go back to nitro.

NuttyProfessor Posted June 19, 2013 Share Posted June 19, 2013 You have to gear down on 6s especially on a 2650 motor and make sure it can take 6s, normally 5s max. Quote Link to comment Share on other sites More sharing options...
WADREW Posted June 19, 2013 Author Share Posted June 19, 2013 If I gear down then there's no point in changing to 2650 surely?What about the 2200 standard motor? Why would that blow too? Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted June 19, 2013 Share Posted June 19, 2013 2650 has more revs per volt remember. Still need to monitor temps and gear down on 6s. Volt up, gear down. Quote Link to comment Share on other sites More sharing options...
Tug Posted June 19, 2013 Share Posted June 19, 2013 What gearing were you running? Did you monitor temps?I have the 2200 in a Super 5, which is 1/5 scale SC and it copes with that! Quote Link to comment Share on other sites More sharing options...
WADREW Posted June 19, 2013 Author Share Posted June 19, 2013 Standard spur with 21t pinion Quote Link to comment Share on other sites More sharing options...
DazzaClio Posted June 19, 2013 Share Posted June 19, 2013 (edited) Probably geared to high, what temperatures are you getting? Get another 2200kv motor go back to standard gearing then monitor temps and go from there. Thanks.

Toxic Basher Posted June 19, 2013 Share Posted June 19, 2013 21t pinion on the 2650 motor running 6s, wow I bet that was quick Iirc castle creations only rate the 2650 motor for 5s max, scrap that, I've just checked their site and its saying the 2650 motor is for 4s max. I've run the 2200 on 6s in many different Rc's and still never killed one, was the esc cutting out from overheating etc ?? I run my vorza's on stock gearing which is a 15t pinion and they still get quite hot after a good bash. What sort of temps have you been getting ?

WADREW Posted June 19, 2013 Author Share Posted June 19, 2013 Quick aint the word lol. Not sure on temps, bloody hot, couldn't touch it Quote Link to comment Share on other sites More sharing options...
WADREW Posted June 19, 2013 Author Share Posted June 19, 2013 Why do hpi advertise that with the 2650 motor on 6s gets 74mph iirc Quote Link to comment Share on other sites More sharing options...
Toxic Basher Posted June 19, 2013 Share Posted June 19, 2013 That's your problem. Way overgeared. The 21t pinion is too much for general use, if running 6s lipo on the 2200 stick to stock gearing. God knows why hpi would tell you the 2650 can be run on 6s, it must be a noob in the office Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted June 19, 2013 Share Posted June 19, 2013 Im willing to bet he never checked the temps, just ragged the **** out of it. Highest ive ever run my 2650 on is 6s on 46/15 gearing but the leopard I use runs pretty cool, im waiting on my 16t. Im guessing its user error here using a 21t pinion.Advertising compared to real life my friend. Quote Link to comment Share on other sites More sharing options...
DazzaClio Posted June 19, 2013 Share Posted June 19, 2013 Quick aint the word lol. Not sure on temps, bloody hot, couldn't touch it Thought so. Try what I said above. You should also invest in a temperature gun to monitor the temps more accurately. Thanks. Quote Link to comment Share on other sites More sharing options...
Toxic Basher Posted June 19, 2013 Share Posted June 19, 2013 (edited) I've never seen hpi say that ? I thought you'd been told by a hpi employee. I've just checked hpi's site and it clearly says if using the 2650 combo it's 4s max Even using the 2200 on 6s with a 21t pinion should be a couple of high speed passes only then cool/check temps etc. looks like its user error all round but why would 3 motors go and no esc ?? That's a bit weird. Edited June 19, 2013 by Toxic Basher Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted June 19, 2013 Share Posted June 19, 2013 If you go anymore than 4/5s on a 2650, you are reaching the RPM limit which is 60000 normally. Quote Link to comment Share on other sites More sharing options...
WADREW Posted June 19, 2013 Author Share Posted June 19, 2013 They say quite clearly. 73mph with 46t spur 21t pinion on 6s Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted June 19, 2013 Share Posted June 19, 2013 (edited) For a quick speed pass, not flat out for a full pack fella, didnt you say 74 mph earlier? Edited June 19, 2013 by NuttyProfessor Quote Link to comment Share on other sites More sharing options...
WADREW Posted June 19, 2013 Author Share Posted June 19, 2013 I said iirc. Wich I didn't lol so I chequed the site and its 73mph. Bit picky arnt you? Quote Link to comment Share on other sites More sharing options...

I'm not saying its right but Hpi do mention the 2650kv motor on 6s:http://www.hpieurope.com/kit-info.php?partNo=101709&lang=en Look at option parts used at 73mph on the speed chart. Thanks.

Toxic Basher Posted June 19, 2013 Share Posted June 19, 2013 They say quite clearly. 73mph with 46t spur 21t pinion on 6s Surely that would be on the 2200 only and as nutty said, high speed passes only and on a nice surface like Tarmac, no grass. http://www.hpieurope.com/piw.php?lang=en&partNo=102703 Quote Link to comment Share on other sites More sharing options...
WADREW Posted June 19, 2013 Author Share Posted June 19, 2013 For a quick speed pass, not flat out for a full pack fella, didnt you say 74 mph earlier? Then they should state that surely ?? Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted June 19, 2013 Share Posted June 19, 2013 Just clarifying. He's right though toxic, upto 73mph on 6s on 46/21 is claimed on the site but using Megabite tyres to give it the grip instead of spinning all its power away I spose. 1 Quote Link to comment Share on other sites More sharing options...
Toxic Basher Posted June 19, 2013 Share Posted June 19, 2013 Ha ha they sure do say 2650 on 6s gives top banana, that's just wrong. I'd get on to them mate and hopefully they'll replace, if you check the link I posted it does state 4s max on the 2650 combo Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted June 19, 2013 Share Posted June 19, 2013 (edited) I can believe 21t on tarmac, I hit 56mph on 46/15 with my 2e on 4s. On grass, 15/16t max on a 2650 Edited June 19, 2013 by NuttyProfessor Quote Link to comment Share on other sites More sharing options...
