Go to sdp.si.com and go to "Buy Online". Click on the Metric Unit button. Then go down to the option for Gears. Then click on Spur Gears, next click on the suboption called "Metal". Then you should be able to adjust the search functions for 5mm bore and Mod1 specs and voila! Metal gears in Carbon steel, 2024 Aluminum alloy, 303 Stainless Steel. Teeth numbers available: 14,15,16,18,20,22,24,30,36,42,48,54,60,72,84,96.
Id be interested in the 30 and possibly the 36 but I am not sure what the "pressure angle degrees" means. It says only 20* is the only one availiable . Now looking at my spur it says 14.5* so I am not sure it will work with my spur gears.Anybody know if they are compatible? It also looks like they sell the same plastic gears up to 28 tooth that kershaw sells. sdpi sells them for less money also but I dont know what the shipping would be.
Thats a description of the Pressure angle. It seems as though it really wont matter, but the 20* is becoming most prevalent.
It specifically says the teeth that are meshing must have the same pressure angle, So those gears wont work with my set up or spur. The plastic ones will but I still don't think they are strong enough.
Neil we are talking about mod1 gears not .8 or 32p gears. A 25 tooth mod 1 is bigger than a 27 tooth .8 or 32p. Bigger than 25 tooth mod 1 steel gear is almost non existant.
Alas, I cannot read, for Im sure the info said Mod1, but then again, I was wrong; rare thing indeed....
Do like those Acer poster girls though, think RCM should sex up its image too a bit...

Will the plastic 30 tooth work with brushless power since the aluminum gear is the wrong degree pressure angle ?
I ran the plastics for 1 to 1 ratio on a 10S truggy and had no problems with them. Ofcourse, your trigger finger might be more anxious than mine........
