forbs Posted March 19, 2012 Share Posted March 19, 2012 Narrowed the motor down for my hyper 7 conversion to... http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=17697 That can take 4s and the 1600kv that can take up to 6s Just need to decide which one is better for my use. Mainly bashing and sometimes speed runs Cheers guys Quote Link to comment Share on other sites More sharing options...
forbs Posted March 19, 2012 Author Share Posted March 19, 2012 Sorry I meant this one http://www.hobbyking.com/hobbyking/store/__17711__Turnigy_XK4074_B_1400KV_Brushless_Inrunner.html 1400kv Quote Link to comment Share on other sites More sharing options...
Nomsicle Posted March 19, 2012 Share Posted March 19, 2012 I have the 2200 KV version in my BSD buggy, with a 17t Pinion on 4S and it's ridiculously fast. Brilliant motors for the money. Quote Link to comment Share on other sites More sharing options...
forbs Posted March 19, 2012 Author Share Posted March 19, 2012 What sort of speeds are you getting mate ? At a guess i mean Quote Link to comment Share on other sites More sharing options...
forbs Posted March 20, 2012 Author Share Posted March 20, 2012 Would it matter to run 6s on a lower kv or 4s on a higher kv is my question Baring in Mind I want to atleast have a go at getting it to a decent speed Quote Link to comment Share on other sites More sharing options...
Byson Posted March 20, 2012 Share Posted March 20, 2012 Can i just say thanks for sharing that link Quote Link to comment Share on other sites More sharing options...
goldblades7 Posted March 20, 2012 Share Posted March 20, 2012 the way i see it 4s is best with 2200kv -2700kv 6s 1400kv -2200kv Quote Link to comment Share on other sites More sharing options...
DreXeL Posted March 20, 2012 Share Posted March 20, 2012 Depends what you mean by 'decent speed', Nomsicle's BSD probably does around 50-60mph, but it's impossible to say for sure without measuring the speed. It is however ****ing quick. Quote Link to comment Share on other sites More sharing options...
Jacksprogis Posted March 20, 2012 Share Posted March 20, 2012 If it keeps up with the flux storm on 3s its quick ! Quote Link to comment Share on other sites More sharing options...
Turner Boy Posted March 20, 2012 Share Posted March 20, 2012 (edited) keda 1900kv on 4's, plenty 45-50mph for bashing, stick a 6s on to push for 70 http://www.giantcod.co.uk/keda-367409xl-inrunner-brushless-motor-p-402371.html Edited March 20, 2012 by Turner Boy Quote Link to comment Share on other sites More sharing options...

They seem too good to be true... All that flavour and zero calories !!! Quote Link to comment Share on other sites More sharing options...
who Posted March 21, 2012 Share Posted March 21, 2012 (edited) I have the 2000kv hobbyking on the way, the one you posted a link too first. I reckon it can handle 6s even though they say it cannot. If you want a buddy code I think I have one... I don't like those pink cans, I had a smaller one and the thread stripped in the front end bell. Then the rotor magnet detached and finally then the rear end bell fell off and I lost it (repairs between each of these of course). My friend had one the size linked by turner and the thread at the front end bell stripped so it just turned and turned!!! I feel that they are low quality and fall apart with medium/heavy bashing.

How would you know if it can handle 6s? Plug it in and hope for the best? Quote Link to comment Share on other sites More sharing options...
who Posted March 21, 2012 Share Posted March 21, 2012 How would you know if it can handle 6s? Plug it in and hope for the best? That was my original plan.... 2000kv motors usually handle 6s. The only reason I can think of that this one might not is if the magnetic material becomes saturated at higher voltages which causes lots of heat but would possibly cause the motor to "over rev" like it does when it's been overheated (de magnetised). For this reason, I will probably measure motor speed with a tachometer at 4s, and if it is 50% higher on 6s then I will consider it safe to try. And if the temps stay down I will consider it perfectly fine. Saying that, my ESC is 4s so I will be sticking to 4s for the time being anyway!
