I still have to test them, but with the right alloys thay should hold up well especially with a full suspension system. Once I get it moving I plan on running a lot of tests including some small jumps. -- You are currently subscribed to the "R/C Tank Combat" group. To post a message, send email t

Will cast alloy swing arms be strong enough? My (limited) experience of alluminium castings is that they are light but not very strong. On Apr 7, 1:59 am, Forlorn Foundry wrote: > I think I've worked out my steering. I have an old Vantec RDFR23 dual > speed control that will be running two dewalt

I think I've worked out my steering. I have an old Vantec RDFR23 dual speed control that will be running two dewalt Drill motors. A Y- harness connect the steering servo for the front wheels too the steering side of the Vantec. Thanks for the help with that guys, I'll keep you updated. I cast some

Thanks for the heads up. I'll only be building the same type of clutch not the whole gearbox. The motor I'm using has a gearbox. One thing I'm having problems with is that on the plans it says to make the clutch shoes from PCB Epoxy/ sheet 1.6 which I have searched for and can seem to find, anyone

Just to let you know, Cerjak's transmission is expensive to build. It has been discussed here on more than a few occasions. When I priced out the non-fabricated parts a couple of years ago, cost of gears, etc. was over $500. Just a heads up. Derek T065 On Sun, Mar 28, 2010 at 9:31 AM, Forlorn

Thanks for all the ideas. I'm still trying to decide how I'm going to do it. I did find this web site http://members.tele2.nl/s_weggeman/CG.htm. I'm thinking of going with a modified version of that clutch system and running a Y harness form the steering servo to a clutch servo. As for the cast a

I'm with Phil on this one but if you want to be authentic then the easiest way would probably be to use individual track motors like a tank and a Y harness connecting the steering servo to the mixer / speed controller for the tracks. Would work best with a mixer that allows you to set the maximum s

Hi Mr Foundry, good to have you on board. Looks an interesting project. Simplest way to do a half-track would be to have ordinary tank steering on the tracks and spring-loaded steering at the front so the wheels follow the tracks. That said, the brakes/diff solution is most authentic but you lose

run a second servo in tandem with your steering servo. then rig it to break the circuit for the inside of your turn. Loosing power to the inside + steering the front wheels may do the trick. you can also try using MAG switches (see speed controls section of the website) because they act as electr
