    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    no worries man, quite a few guys are running them using thermal tape rather than paste and it seems to work well

    Hey mate, that would be the standard size set, they'll fit most motors from 220mm to 240mm diameter, which fit MXUS, QS 205, Leaf, Crystalyte, 9C and other common sizes NOTE: QS273 or TC Crown hubsinks are larger size but also available.

    Just the corners of the piece, sit it up like a bridge and tap or push the center down untill the radius matches your hub pretty well and use that one to do the rest they do pull down during heat cycles so fitment isn't critical there's some more info here on general fitment...

    Yep you should be just able to push them down by hand with the curve facing upwards, get one to match exactly then use it as the template for the rest, takes about 5 mins

    I believe Justin did the wind tunnel testing and drag was negligible as its a lubricity compound as well

    Finally! got the Qs273 Hubsinks working! one tube of statorade is perfect with them, and they just need a little massaging with the BETA versions to have perfect contact but they are very effective for high power overheating hub motors!

    Hey mate The pricing on Grin and the Hubsink website are the same, both kits include the nuts, bolts and thermal paste, both pages have the statorade as a seperate product. the Hubsink website ships from Australia and the grin one from Canada

    may even be ok with a 2mm silicon thermal tape under in place of the thermal paste, pads it out snugly and good heat transfer

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    Thanks mate thats definately handy, my main concern is the QS 205 ones dont match the drawing or specs from QS (295mm) in real life after paint etc and the tolerances are so tight that i actually spent quite a bit of time with trial and error to get the final hubsinks to truely fit correctly so...

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    I have a bit of time on the CNC this week does anyone with a 273 at hand have the exact measurements for the magnet ring diameter, i have been given 3 or 4 different ones now and want to make sure im accurate, it looks like 295mm is the average so far? what is the true clearance between...

    The gap works as a spring to keep tension on the assembly throughout heat cycles you are correct Don't tighten them right up till they touch, just untill they are snug and equal around the hub

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    people have and it does help, (if your magnet ring gets warm, the hubsinks will pull more heat out regardless) but they work so well together i wouldnt recommend doing one without the other, unless you have a specific reason to need to do so :flame:

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    Ive had a few enquiries for one-off versions of the hubsinks for non standard motors and now i have my CNC back up and running ill do a small-run of billet Hubsinks the main enquiry i have is for the QS273, but i have been given 4 or 5 different curcumfrences of the magnet ring, i would be...

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    haha absolutely awesome, i did similar but not as thorough to mine, and it was crazy how thick that paint was, almost a fill mm or more i would say, they really lay it on there! if you are chasing ultimate thermal coupling this would certainly give you one less thing between the hub and the sink!

    Hey mate yep that's my tooling company i have them up there as well as http://www.hubsink.com - ebay does take a bigger fee but it seems sometimes people find it there before the website the only way to do that would be to go around with a coping saw and trim them down, i have done it once...

    you shouldn't need to pad it at all they should pull tight around your hub do you have a photo?

    Automatic Wheelie control / Launch control module Beta testing

    interesting you mention the death bike because without using launch control (low angle) mode when I was doing my 0-100 runs I was mousetrapping the throttle and backing off too much as the front came up, then letting it down too much and losing speed to get the nose to come back down etc with...

    Hi izeman! it should definitely work with any drive type as long as you can tap your three throttle wires all good?

    Automatic Wheelie control / Launch control module Beta testing

    apart from the fun side of it i haven't really made it clear that i would also it was initially designed for saftey, to stop flipping accidentally which has injured a few people on powerful ebikes, it wont entirely stop whisky throttle but it can be set to stop the front coming up past X angle

    I've been quiet but I've been busy since HubSinks! they are related though because as i kept adding power, i needed more control The 4th version of the Wheelie Box / Launch Control Module is done after almost 2 years, its fully potted and shock/waterproof now and i'm ready to start organising...

    How did you go once you got the FF in there ive been away so apologies for the late reply but yep, the FF is very important and doubles the effectiveness of the Hubsink alone!

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    i've been doing some more seat of the pants testing with the Hubsinks and statorade and i've found when first installing the statorade putting the whole 10ML in seems to be the sweet spot (at least for the QS205 and MXUS motors) Some makes its way into the nooks and crannys, and seems to leave...
