AdamR Posted August 5, 2014 Share Posted August 5, 2014 An expensive gimmick, nothing more. If it was a real dyno, I would be all over it like a rash! 1 Quote Link to comment Share on other sites More sharing options...

J450n Posted August 5, 2014 Share Posted August 5, 2014 Someone should be able to convert it into a dyno, when they do, give me a shout. Quote Link to comment Share on other sites More sharing options...
louder Posted August 5, 2014 Share Posted August 5, 2014 Just throw on a telemetry kit. Mount the RPM sensor on the revolving bar and you will get a true wheel RPM read out. My concern would be tyre rubbing and the car popping off the rollers while it moves around, no car ever sits straight, at least none do that I build haha.

lel-95 Posted August 5, 2014 Share Posted August 5, 2014 (edited) its going to be a disaster if your steering trim is even the slightest bit out Edited August 5, 2014 by lel-95 Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted August 5, 2014 Share Posted August 5, 2014 i like this idea. would mean i could test my leccy cars in my room proberly, i can see this selling to people who (like myself) can't get out to a wide open field to test their cars. at least with this i can try a decent range of throttle in put without making a hole in the wall.

Noj Posted August 5, 2014 Share Posted August 5, 2014 ^^ you say that, however, I forsee many holes in many walls when folk exceed a safe speed/have huge ballooning and take off 2 Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted August 5, 2014 Share Posted August 5, 2014 ^^ you say that, however, I forsee many holes in many walls when folk exceed a safe speed/have huge ballooning and take off this is true. also they mention 1/5th scale....if i put my bajas on them the tyres would just lever it off the rollers instantly so i couldn't do it. with them could be ok with my 1/8th buggy if i tied it to something first, or my mini recon maybe.

J450n Posted August 5, 2014 Share Posted August 5, 2014 We need scaler rachet straps to tie the cars down! and gopro vids of engines/motors eating themselves Quote Link to comment Share on other sites More sharing options...
Pistonhead Posted August 5, 2014 Share Posted August 5, 2014 I'm with Thunderwolf on this. Esc calibration without risk of tyre marks on carpet and/or skin or damage to belongings lol Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted August 5, 2014 Share Posted August 5, 2014 i just looked at the cost. about $70 each, not including postage. thats $140 if you got a 4x4 crawler. $280 if you want one for your losi 5ive or maverick black out. i like the idea, but damn, i could make my own, sell them cheaper and make some money.

johninderby Posted August 5, 2014 Share Posted August 5, 2014 (edited) Lets see.....two long pieces of angle bracket with holes drilled close together for mounting the rollers screwed down onto some MDF for a one piece set-up or make two individual ones as in RC4WDs design. Make the rollers from four pieces of tube with four more pieces of slightly shorter tube that would be a slip fit inside. Then fit bearings in each end then four more pieces of smaller tube that would fit the inner dia of the bearings and finally four pieces of threaded rod to fit right though the small tube and through the angle bracket with nuts on the end. Add washers as required. Low tech and simple to make and would be a small fraction of RC4WDs price I 'm sure. John PS If making it myself I'd use thick wall ali tubing for the rollers, machine out recess for the bearings and use solid rod for the shafts and thread the ends.

RCbutcher Posted August 6, 2014 Share Posted August 6, 2014 Is it any differennt to just putting a brick under the chassis or do these have some resistance to mimic load or something. Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted August 6, 2014 Share Posted August 6, 2014 Is it any differennt to just putting a brick under the chassis or do these have some resistance to mimic load or something. these have the weight of the car on the wheels, so yes, they would have some load on them, rather than just free spinning (which is bad for the motor i'm told, have my doubts on it being true) Quote Link to comment Share on other sites More sharing options...
