T-maxx going brushless...tips?

Any ideas on where I can get a motor mount for the Feigao 540C-7XL?
Being that it's got cooling fins, I'm planning on making my own motor clamp using some threaded rods sheathed in carbon, aluminum locknuts and then a strip of aluminum at either end of the motor.
Ideally, I would use a motor mount that has tabs on either side of the motor with drilled and tapped holes for the threaded rod, but I may be asking a bit much there.

My guess is a 1/4" L bracket-type mount would work. Unfortunately, I don't have any decent metalworking skills/tools and my experience trying to work aluminum with a dremel has been less than satisfactory.

I have some thinner aluminum that I could chop with a dremel, but my fear is it'd be too thin and bend.

I saw some posts about a dude named ColdFusion who has had some motor mounts made and was thinking of asking if he could have a custom mount built.

Any other keen ideas?

You could try calling Mike here at RC Monster to see if you could work something out with him. He has access and skills for making dreams come true with RC CNC issues.

Also you can still try DIY and see what you can come up with. Working with aluminum is a little tricky if you have done it before. It is very soft and requires a little patients. Don't depend solely on a Dremmle tool, but they can be very useful for tinkering with manufacturing small RC parts. The main thing is not to get in too much of a rush with your project, hence forcing shortcuts. Once you cut things the way you like them it will require some grinding, sanding, and polishing with super fine sand paper (1000 grit) to make it look professional enough to meet your own standards. You won't really know what you are capable of unless you give it a shot. Aluminum is not that expensive for experimenting with, and as the saying goes "if at first you don't succeed, try try again". Honestly you may surprize yourself. Good luck with that.

You've encouraged me.
See what I can scrounge up at the local junkyard and go at er with the trusty dremmel.
I do remember trying to grind at a cooling head awhile back and the aluminum kept gumming up the grinding stone or sanding drum.
Should I be using carbide tips or something? There's gotta be something that works better and isn't a cutting disc...I'll google it.

Danke-

I am glad to hear that. I have been using one of the newest Dremmel cutting wheels myself and it seems to work ok for me. It is a little bit heavier than the usual ones in the kits. Just about anything you use for grinding or sanding will gum up over time or if you use to high of a speed. You can either clean them off or have spares to switch out heads. Like I said it tends to be kind of soft and a little tricky, but it all works out in the end. Using a mill of drill press works a little better in some cases, depending what it is you are trying to accomplish. There are a few guys on here that do a lot more aluminum work then I do, so maybe they will chime in and give some supportive advice. Mike, Metalman, Linc, Serum. You guys are the master in here. What do you think???

I am far from master status! But thanks for grouping me with the greats Jerry! I am flattered!

I usually cut al with a fine tooth metal blade in a std cheapo reciprocating saw, soem people call it a jig saw. You could use a sawzall, but they are not as handy as the jig saw, the blades are too wide to make good cuts in tight areas. Variable speed is handy too. Get some good metal files, they are very handy too. And a drill press, even the 50 dollar harbor freight kind are invaluable. Also buy a good set of drills, and some cutting oil while you are at it. I also have a bandsaw, but mainly use that for cutting plastic, it is not the best tool for cutting al or steel.

I do intend on buying a small mill, or combo machine (mill and lathe). Small ones can be had for less than 500 bucks and that would most likely let me hone my machine tool skills (which are non existant at the moment!)

Paitence is a good thing for doing metal work, Jerry is right about that one. You will have to make a few items and then you will get better, at least I had to do that!

Oodles of weasels....man, I was just thinking about that on my way home from work today when I heard this noodle commercial on the radio.

Cool, so get a drill press and some good cutting gear.

I jest...that's not mine. :)
...but I have seen the aluminum metalworking live and in the shavings, so I know what you mean.
Home depot, here I come.

Now that is just sick. Someone is having way toooooo much fun there. Nice shop whom ever it belongs to. I wonder how much time is spent playing in that little hole in the wall.
