[TANKS] Re: Doug's ESC

The Victor 883 comes with an integral cooling fan. It's not something that I put on later. I've never had the thing overheat, so I don't know what happens. I checked the manual for a mention of a thermal shut-down feature but didn't find anything. No help here. Sorry. Joe and some others use Vi

[TANKS] Re: LOPPEM

That sounds like a good idea. I'd like to see the hopper internals during firing myself. I need to develop a faster loading system on my tank, and I like the idea of a semi-permanent lid with a hole. -Doug From: rctankcombat@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ch

So far, so good with the paint. I roughed up the aluminum with a small wire wheel attached to a cordless drill first. From: rctankcombat@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Saturday, September 20, 2008 10:00 AM To: rctankcombat@googlegroups.com Su

[TANKS] T058 updates

There are a few small updates to the Bad Kitty web site (http://home.comcast.net/~dwconn404/RCTank/Tiger/TigerOverview.htm). A couple of photos are below. The tank is also sporting a new 5/8" rear axle, 5/16" stainless steel rear tensioners, and a lower hull and road wheel paint job. I had plan

Wow, that looks amazing. I don't think it's built to move, though. Maybe that's what the 'R/C upgrade' is for. How do you suppose he fabricates those long curved frame members in the photo of the separate frame and body ? Any ideas ? - Doug -Original Message- From: rctankcombat

[TANKS] stepper motors

Hello - I'm starting to think about the next tank. It will probably get built in about 2012 ! I'm going to go further in the robotic direction. I'd like to use a stepper motor for turret rotation, but I don't have any experience with them. I've found inexpensive bipolar chopper drivers that

We generally agree that building our own motor controllers is a bad idea because there are good commercial products available that handle that need better than we could build on our own. Why, then, would you build your own controller computer ? There are tons of embedded controller boards out ther
