Anyone running these yet? I was looking at them here: http://www.rcmart.com/catalog/rc-axi...cPath=595_1160 I thought they might be a good investment. Any ideas or input with them please? |

Actually a portal axle setup, wish they had a high steer arm though. I would like to try em, when I can get them.

Those are pretty sick. I agree with gunnar tho. I would get some if they had a high steer arm. Looks like your gunna gain about a 1/4 in GC.

| Yes, I don't think there is reduction either. I just said portal because that's what they remind me of, and if there is no idler gear, motor rotation would have to be reversed. Looking at the cover, it looks like a two gear setup.

| Probably why they only sell them in sets of 4. Interesting to see them doing a part like that. If they are strong enough I would even consider running them on just the rear of my berg.

In certain bind situations, could also put additional stress on the end of the axle housing too. More distance between center of axle and stub centerline=more rotational leverage=twist off the end of the housing.

I saw a picture of the inside of them somewhere. The top gear was smaller than the bottom gear. There looks like there is some reduction though not much.

I wonder how much you actually gain in gc. it looks like they will make you wider as well . seems kinda cool , makes you wider while keeping the width/gc of axle in somewhat the same ratio as before. but like gunnar said , they will probably twist off the axles c's unless maybe they had enough reduction to help with that. |

Last months issue of RC Car Action had these in there. According to them, these portal setups provide a 1.6:1 gear reduction

| Yea, looks like 10 and 16 on the tooth count. Reverse motor rotation. Yes they would raise COG, but lowering belly height some would help. Hard tell if the shafts are fully bearing-supported, the top shaft might be a bushing, but could be a tiny bearing too.

Umm, since the arm is centered vertically couldn't you flip them and lower the CG?

Yeah, a little bit of reduction. Might not be a bad idea for the rear...
