Here is my washer , could be 2-3 mm too large, better safe than sorry.
17mm inner diameter of the washer.
Yeah there will be air only, I washer is only 3mm thick or so but saying that I might get some washers under the screws;) Iāll let you know how it works once I get them, 2-3 days from now.
I received mine today! Fits perfectly to my completely round cheapy trucks. The āteethā on the clamp part clamp to the aluminium and dig in to keep it in place.
Iām milling a slightly larger centre hole though, but only part way through the mount to accommodate the circlip on the shaft.
Cool, let us know the specs, then Iāll email them to HobbyKing customer services and get them to put them up on the website haha - that wouldnāt be rude at all
