Since seeing how pretty and strong the attatchment chain is, I have been enamored with the idea of using it to create a Battlebot (preferably a 12 lber). x12.putfile.com/1/1608052332-thumb.jpg What I’d really like to do, though, is use two ICE’s (internal combustion engines) to…

having dabbled (sp?) in RC everything for many years i might be able to shed some light on the situation. first rc cars typically use a special glow engines different from planes because they dont get the air flow for cooling you will most likely encounter a similar situation. t…

Sigh… That’s depressing. I was hoping to be the only guy around with a 12lber that ROOOOOAAAAARRRRRRRS. :laughing: About the air cooling, yea, I noticed that yesterday, but I stupidly told myself that I could just put a fan in there. HELLO, EARTH TO NICK! I hadn’t even thou…

with a grain of salt you can assume that with some of the latest brushless set-ups can compete pound for pound amoung glow set-ups. so you wont loss to much of that ower you want, and you can always run a weapon off a glow engine :smiling_imp: brushless motors come with a kv and…

Nick why not try something like a 23cc engine? They use them on the Marders, HPI Baja, DuraCrap 1/5th scale cars. Only thing bad about the RC engines (2 stroke glow ones) is if you don’t tune them good, depending on the engine, they’ll flameout. I remember my TRX 2.5 would not r…

Well, I’ve looked at those, before, and there was 4.69 reasons why not to use them. :wink: That kind of weight would force me into making a 60lb bot, in which case, there are other engines that output much higher torque for the same weight. I’m putting this project on the back…

Nick, Have you considered Diesel-Electric? It would give you the ‘ROOOOOAAAAARRRRRRR’ factor without the transmission headaches. Wada in Japan builds nitro-methane powered diesel-electric model railroad engines. users.erols.com/diesel/wada/gp9specs.html#

Wow! What a neat idea… Of course, the one’s they make are way out of my price-range, but it looks like I could make my own. I read that site, and checked the three links that it had on the subject, but I can’t seem to find anything in-depth on how to determine what motor is su…

The Wada’s are indeed pricy. That reflects the craftsmanship and modeling detail at least as much as the propulsion technology. I know of one home-brew implementation of this approach for model railroads. As I recall he used a marine engine coupled to a cordless drill motor fo…

Hmm… If I have to put a battery on-board, then that defeats the whole purpose. :frowning: I understand what you’re saying about the voltage and amperage, but I still don’t see how I can determine the output voltage and amperage before actually buying the engine and motor. Aft…

Click on the motors section and look for small ones, if they are too large try the antweight section.
