Scaleauto Crowns

[HomeRacingWorld]

I am pretty much a Slot.it guy, but when my size runs out (and it does all too often) I choose different brands to try.

On my last build I tried the Scaleauto crown.



The option of removing the flange is a good thing if you do not need it.

Gear mesh is pretty smooth too. I might use these more often.

Anyway, old hat to most of you.

Harry, we have been selling them for a long time. Definitely not a big seller but I think more and more people are giving them a shot. The Sidewinder gears are really nice very quiet gear mesh.

Thanks Mike, yeah I think I'll grab some more my next order.

I just ordered 2 for some upcoming builds based on the review. Liked the option of not having the flange.

Thanks Mike, your order went out today.

I do like the idea of removing the flange when not needed
with this combined with carbon fibre axles ball race bearings and lightened wheels
makes for a very light and friction free rear end set up

I have tried using one in a set up just the other week
it came out of the Merc GT3 that I have converted to sidewinder
but unfortunately it was very buckled and no amount of heat method managed to get it straight
enough to get a nice gear mesh
but do plan on trying again sometime in the future

Another advantage of this type of gear setup is you can set your gear lash if you use axle spacers.

I never use a gear boss if I can help it. I use axle spacers and adjust things for minimal side play. The easy way to set the gear lash is to put some plastic bag material between the crown and pinion before you tighten the set screw. If you do that the mesh will be perfect.

Interesting that so often we all independently take the same path. Several times, I have chucked a crown into a lathe and turned the flange all the way down.

I usually just trim the motor shaft off. With the brass brackets I have been using, most are set too far to allow the shaft to work anyway. So cutting the tube to correct length is my method most often.
