As a 4 wheeler , People always break their 5/29 gears before people break 4/88's
the reason is more tooth contact
Same thing here for the Helical ,more angle provides more contact, more gears evenly distribute the load, not just one tooth at a time.

Not my thread , or would supply name part numbers. It was just an example

Good day

Helical does have a problem though, it loads the pinion races perpendicular to their rotation. As the helical gear rotates along the spur it is constantly trying to force itself away from the spur. People with high torque setups would have issues with the inner pinion bearing coming apart due to this load. A thrust bearing would be a good item to add, but space is usually limited in that area...

previous post was purely sarcasm BTW...

Again Since were using real world examples, what type of gears do indy cars use (straight cut) What kind of gears do non snycro trans use.... strait cut as well.. Reason for that is weight/strength, helical offer quieter operation..

Back to rc application... many ON this forum have proved that the side loading of the helical gears utterly destroy the inner bearing..

If this thread bothers you so much then leave it and dont look at it again..... im not going to waste any more of my time responding to you..
