Raman36 1656 Posted September 23, 2020 In preparation for the brushless motor, I did some shimming on gear box. Shimmed counter gear towards the spur gear side Drilled out gear box to attach motor via screw. Of course drill bit moved so I had to make the hole larger. Im a terrible machinists Motor spacer from TB05 worked out perfectly to space motor from gear box 3 Share this post Link to post Share on other sites
Raman36 1656 Posted September 23, 2020 Shaved down marking on Motor so it would clear housing Checked Mesh and marked gear cover for trimming to clear button head screw Added my favourite lube to moving parts Some shims to take out play Now this bit here .. I spaced out the RCChannel outdrives so that I could used CVDs. The Dog bone is from M Chassis. The Axle is from the frog. Then I spaced it out on other side of upright as well. This is all so that I can use the big bore TRF dampers. Now for the radio box. Removed wire grommet. Ran all abc wires plus sensor wire and sealed with hot glue. Finished product, SRB with Brushless censured motor :-) 4 Share this post Link to post Share on other sites
ruebiracer 1046 Posted September 25, 2020 Totally interesting mods Raman! So as I get it, you used the CVD setup instead of the original RC channel drive shafts for widening the track width, and for using a CVD? And this gets you more space for the dampers with spring setup? Very cool. Our cars are really somehow identical. I even have the same receiver! Just have the positions switched ESC and receiver compared to yours. (ESC too high with fan to place it in front.) Don´t care about the too big hole, thin washer under the screw and nobody will notice! With spacing the motor slightly out, I guess you will have to run it without the plastic cover? Shouldn´t be a problem, as the Novak is probably without holes in the back... Please let us know, how the first ride with the new powersource was! Share this post Link to post Share on other sites
Raman36 1656 Posted September 25, 2020 Correct. The RC Channel axle was too short for the wider set up.. I went with this route so the tyres wouldn’t rub on shocks upon compression. The back motor cover wouldn’t serve any purpose other than to create heat i wanted to move ESC to back centre, but I had a wire for lights soldered to it with a connector to front of radio box.. decided I don’t want to mess with it. 1 Share this post Link to post Share on other sites

Ah, cool, I thought that is a mini switch for the ESC. No worries, looks all tidy in your radio box! I use M-chassis dampers with special piston rods and without spring (would not clear the tire under compression, so I have to use the original twist beam setup. But works still good enough for me. Next year I really want to do my original ABS body finally, I´m still using the Parma Lexan one. But a Scorcher really deserves the extra details of this nice part of Tamiya history. And running on the beach mainly, the risk of damage to it is quite low. Thanks for all the detail infos, really helpful! Share this post Link to post Share on other sites
Raman36 1656 Posted September 26, 2020 I did an initial run with the 15T / 70T pinion and car was really slow on 13.5. So o changed to 20T / 65T.. haven’t run it yet.. hopefully will get a chance this weekend Share this post Link to post Share on other sites
