[TANKS] Re: New here and thinking of building a half track
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.

Will cast alloy swing arms be strong enough? My (limited) experience of alluminium castings is that they are light but not very strong.

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 know were I can find some? -- You are currently subscribed to the "R/C Tank Combat" group.

Re: [TANKS] Re: New here and thinking of building a half track
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.

[TANKS] Re: New here and thinking of building a half track
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 aluminum tracks. It's just a matter of making the wood patterns. I think there's about 80 links total on a Sd.Kfz.250; so, if I do 10 track patterns that's 8 pours for both tracks--not too bad. I have been doing aluminum sand casting for years and own all my own equipment. Right now I'm working on 6 trophies for the local Ducati owners group, I also did there trophies last year. I'd be willing to do rough aluminum castings a little over cost for people here if anyone's interested. I can cast up to 10 lbs of aluminum per pour. I can make the patterns or you can send me a pattern you have made. I'll get some pics up when I start casting parts for my halftrack. -- You are currently subscribed to the "R/C Tank Combat" group.

[TANKS] Re: New here and thinking of building a half track
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 steering inputs to stop your half track from doing a neutral turn at full lock.

[TANKS] Re: New here and thinking of building a half track
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 a lot of power on the turns and you've not got a lot of room for bits and pieces under the 1/2 track.

[TANKS] Re: New here and thinking of building a half track
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 electric speed brakes when "closed". when you turn one direction or the other, the servo arm will move the "inside" MAG swith to neutral - i.e. both switches open. If you want to keep it simple and forego any kind of skid steering, try using the axle from a large R/C truck like the Nylint Rock Crawler. Their drive axles are posi-track so the tracks shouldnt fight you when you turn. - Martin On Mar 21, 4:32 pm, Forlorn Foundry wrote: > Hello everyone, I just signed up for this group but have been reading > it for months now. > > I'm keeping it small and building a (Sd.Kfz. 250/8) Neu with 5cm Pak > 38. > > It will have 1/8 welded aluminum hull, cast aluminum tracks and > running gear (with resin or rubber tires cast on to the rims), and > torsion bar supension.
