I decided to install a faster motor in the Tumbler. I first installed a Tamiya RZ 23-turn brushed motor but the MFC-02's ESC couldn't handle the load and would go into thermal protection mode every time I touched the throttle. Then I tried a Tamiya RS540 Sport Tuned motor (don't know if it's 23-turn or 27-turn; there are two different versions) and while it worked better the MFC-02 would still shut down if I accelerated too hard, especially from a standstill. I was able to turn a few laps in the street in front of the house with careful throttle management and while the Tumbler did go about 25% faster it was too difficult to control and I even did a powerslide when I accidentally turned too sharply under power and I thought it was going to flip over with those big rear tires providing so much grip but it came out of it OK. Considering how hard it was to obtain the original Tyco body and all the hard work I put into building this thing I decided to reinstall the stock motor because with it the Tumbler accelerates great, handles great, goes plenty fast and I don't have any of the thermal shutdown issues. It turns out the Tyco Tumbler's stock motor is not a "silver can" at all but actually a Gold Effort Electric GCR534DM motor. I couldn't find out online how many turns it has but since I had an extra non-working one I unwound it and it is a 36-turn motor. I actually counted 37 turns when unwinding it but I could have lost count or it could be a 38-turn but I...Continue Reading

I have always wanted a big RC Batman Tumbler ever since I first saw Batman Begins in 2005. The biggest RC one they sold was a big 1/6 Scale Tyco version at Wal-Mart in 2005 but it was more toy than RC car in that it was a little out of scale, the front wheels didn’t turn and the back wheels were made of plastic. Also it came with a push-button remote so it didn’t have proportional steering or throttle. Another 1/6 Tumbler was made by Hot Toys and while it is almost perfect in scale, it isn’t remote controlled, is very fragile and now costs a small fortune. The Tyco version was made out of a single-piece, molded nylon plastic shell that is very durable since it was designed to be played with by kids. I also liked the hollow design of the Tyco for another reason I’ll explain later. I managed to find one used in good condition for $200 on eBay. I did a lot of Internet searching and found one person, “Porkchop”, who managed to install RC rubber tires on the back of his Tyco and I found another person, “FLMike”, who devised a steering mechanism for the front of his so I decided to combine these two mods along with a few of my own.
I couldn’t figure out how Porkchop replaced the Tyco’s tires with IMEX 7404 Swamp Dawg tires but after studying his picture closely I finally figured out he just trimmed the sidewalls and stretched them over the Tyco’s. Brilliant! That means I didn’t have to replace the...Continue Reading
