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!

no worries mate if you are looking to cool your ebike hub motor, the hubsinks will do that no worries, you can purchase them from anywhere you like, the statorade is seperate but highly reccomended. grin hubsink -...

same mate, havent seen you on FB since you left but im still trawling the forums, been working on finalising the wheelie box! awesome man! i have an electric supercharger project i need some punchy small packs for ill shoot you an email!

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

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...

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

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:

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...
