Butler 338 Posted January 4, 2012 Decided to flog my 1/10 scale off road stuff and build something strong that I can take anywhere. A mate had been singing the praises of his old school Hyper 7 for sometime, so I got him to source me one. Share this post Link to post Share on other sites
Butler 338 Posted January 4, 2012 After a much surfing around the web, its seems the most common battery source is 4s lipo, so settled on 6s. lol. I don't like the idea of running the battery down one side, so decided a twin pack setup would work. Plus I have the option of running 3 or 6s. Looked for a motor and settled on a leopard 2000kV.

Butler 338 Posted January 5, 2012 Picked up a second hand Toro 8 esc and tested the electrics with the batteries I had. Appeared to work. Ordered a 13T pinion which I think is low, but good for testing without overloading drawing too much power. The RC monster mount arrived, very nice bit of engineering.

Butler 338 Posted January 5, 2012 This is where the motor should sit. Share this post Link to post Share on other sites
Butler 338 Posted January 5, 2012 This is normal layout. Share this post Link to post Share on other sites
Butler 338 Posted January 5, 2012 But I wanted to put my twin batts at the back, so I cut the chassis and rotated the whole mount and centre diff 180 degrees. Share this post Link to post Share on other sites
Percymon 2184 Posted January 5, 2012 Much better layout - been weighing up similar options for my NDF-01 conversion, although looks like i'll also have to fabricate a replacement alloy section which sits in the plastic chassis tub as the stock Tamiya nitro one isn't particularly easy to mod.

Butler 338 Posted January 5, 2012 My lipos came and I lashed it in the car and tested. Performance is mental. Share this post Link to post Share on other sites
Butler 338 Posted January 5, 2012 Made up a decent mount for the batts and ESC. Share this post Link to post Share on other sites
Butler 338 Posted January 5, 2012 Installed. Space is tight. The motor shaft is about .5mm from the left lipo, which is in turn .5mm from the rear lower wishbone. The motor is also almost touching the steering post. Share this post Link to post Share on other sites
Butler 338 Posted January 5, 2012 Since completing the car I got about 1/2 a battery pack of use before the ESC failed. It seems the BEC has died on it, as I can get it too work with a seperate pack of 4xAAs. I ordered a new ESC from HobbyKing which I am in the process of fitting.

Wez-li 1790 Posted February 19, 2012 Any update mate? Share this post Link to post Share on other sites
Butler 338 Posted February 20, 2012 Hi, Yeah I got it running with the Hobbyking esc and is still mental fast. However I had a few issues with screws backing out, and the diffs are a bit loose, so I decided to rebuild the whole car. Found lots of parts that had damaged threads and bought some thick oil for the diffs. Just the front end left to put back together. Awaiting a shock shaft and a diff seal. Once its running again I might look at finding the best pinion size. Cheers, Share this post Link to post Share on other sites
