R/C Hasbro M3 halftrack

Hi guys, I just wanted to share some pictures of the m3 half track I have been R/C-ing. It went fairly easy as I used a track drive unit out of a Stuart tank and just replaced the final drive out put shaft with a longer one so I had 2 sides to work with. The drive wheel is 1/2 Stuart and 1/2 m3 as both fit into each other so the tracks power only on the inside edge, The tracks are Stuart tracks cut down to length and the whole set up works well. Still need to install a radio and work on the steering but im not thinking it should be much work as the front end is very stout and the wheel already steer so most of the work is done. The nice thing is the main gun covers the motor/gear unit so there is not much left to see of the install....will post more as I progress.................................mule

Very clever. I really like the look of it without the rear body. Shame they didn't produce some kind of flatbed or small fuel tanker.

Mule,

Any chance we might see a video of this baby in action. I love you conversions and am thinking of attempting one of my own. Thanks again for the inspiration.

Cheers,
Paydan

Can you show how you connected the Stuart drive sprocket to the new drive axle? Ken.

Hi Ken, The Stuart drive sprocket breaks down into a couple of pieces, I removed the outer sprocket and just used the center drum and the inner sprocket so the track is only powered by the inside edge of the track. I did this as the "drive" sprocket of the m3's outer half fits into the Stuarts sprocket so you really donít see the Stuart's gear and you maintain the look of the m3's running gear. To attach the sprocket to the drive shaft I bought a new set of "shaft to sprocket" connectors that I think the old Field Of Armor sold and bolted them to the sprocket with a blind nut. then they just slip over the end of the axel shaft and tighten down with a set screw. If you cant find the connectors anymore as I looked before I posted this and could not find them you can use 4 Wheel collars that R/C airplane flyers use to hold their wheels on the landing gear shafts. I try and use 4 if there is room if not 3 will work, slip them over a wood dowel to line them up then solder them together and you have a coupling. Home depot sells a brass nut that "almost" fits the inside of the Stuarts sprocket ( donít forget to get 2 screws with the nuts about 3-4" long ) you will need to file the nut down some to get it to fit the hex pattern of the drive sprocket. Cut the end off the screw so you have a "threaded rod", screw the nut on and you want to put it in the sprocket so you have enough sticking out the end of the sprocket to place a cap nut on it wile making sure you have enough to fit into the coupling and keeping the filed down nut in the hex end of the sprocket .....lol.... once you get the length right then solder the filed down nut to the screw as you donít want the screw to be able to unscrew it's self. Once you are happy with the fit you can use epoxy and fill the void around the screw for some more strength and if you need to remove the sprocket from the shaft just loosen a set screw on the coupling and pull it off.
