Motor mount construction

I'm in the process of converting my hyper 7 to brushless. I have threads about making motor mounts using angle aluminum. Today I bought a nice piece of aluminum from a local scrap dealer. I love places like that, but anyway I have a question about the aluminum.

The angled aluminum is slightly fatter in towards where the angle is and gets thinner towards the outer edge. So when I mount the motor it, the motor will will be mounted at a very very slight angle. More importantly the pinion will be closer to the spur on the motor side. Were talking about a very very small difference but, I guess my questions is that a big deal? Should I even worry about it?

how little? if its more and about a 1/32 or so i would just bent it a little.

Welcome to the forums, cartwheels!
If I am understanding you correctly, the motor is leaning a little vs. being perfectly parallel with the spur? Perhaps this is partly due to the weight of the motor? What motor is it? When you land a jump, this distance may become greater due to flex in the motor mount. It is hard to say without actually seeing it, but if the angle plate is thick enough, the flex should be minimal(if the plate isn't think enough, the issue will worsen under high stress as I just mentioned). You could also place a washer under the low side of the new motor mount, to bring it back to level.

It's been a long, long time since I've been in a geometry class. Can't even remember how to figure that one out!
I never thought about bending it. If there is a problem that is what I will do. You know the more I look at it the more I think it's not going to be a problem. I thought about shaving it down, but that would be very hard to do. I don't really have the tools for that. Thanks!

Good luck with it!

Thanks for the welcome. You've got a nice site.
I'm actually just getting ready to construct it. I just looked at it again and I realized that it was just excess material from when it was previously cut. So it is a non issue. The angle aluminum that I got is 1/4" so it shouldn' flex but hopfully it's not too thick either.

1/4" aluminum angle is definately pretty thick! On my 1/8 buggy, I have constructed a complete slipper clutch/motor mount assembly. I used 1/4 for the motor plate and frontal bearing support. With that angle, you will never have to worry about a bent motor mount.

You shouldn't have any trouble with 1/4" material. A little heavy, but it shouldn't flex at all.
Thanks for the site comment. I hope you stick around and enjoy the forums.

Welcome aboard there cartwheels. Do you have any pics there catwheels? I like to see what you got. Can't never see enought projects people do.

I'm in the parts gathering stage still right now. So as far as pictures go, its just a nitro burning hyper 7 and some raw parts. Not sure if there is much to see right now, but I'm going to go look. By the way, I'm "muck" from rc zone. Maybe I'll take some pixs of my rustler a project in motion, .

Hey muck! I am tcolesen over at RC Zone. I too would like to see some pics of your buggy.

Here is my Hyper 7. With a MBX diff in the foreground. My plan is Feigao 10L , MGM 160 and I be using 4s Lipos.

And my Rustler. Its about 3 years old. I have had to replace all the plastic in the last year or so due to brakage of some form or other. It's has a Feigao 8s, uf75 and I run on 2s or 3s. The rear end has some toe in and Mip cvd's. The toe in really makes a huge difference.

Here is another view of the rustler. the aluminum over the uf75 is for holding a fan. Notice how the rear of the body has rubbed off over time.

Welcome aboard, carthweel! Nice RCs, please share some pics of the finished buggy!
