Well, I don't know if this thread has ended. If it has ended and I just found it.... Bummer. I have been working on a Nitro R/C crawler for about a month now. I am using a Tmaxx 2.5 chassis and drive train. The chassis is going bye bye in place of a hand made aluminum chassis. The one off print drawing and measurements have been a bear but I am finally making some head way with manufacturing (and designing it so it's appealing) the chassis. I have locked the front and rear arms and as soon as I have the first chassis built I will work on the 4 link system. I have read through the feed and seen some haters, but mostly some serious ideas I will use on my own rig. I am going for the horizontal mount for my motor, but I think i am a few months away from that process. I soon will be locking the diffs, and the transmission is a whole other story. As far as over heating goes... I have tested quite a few different applications. I wnet with a standard CPU fan, this worked fine for a Maxx in standard motion (i.e. fast) But ripping it around my backyard at a slow pace, but keeping the RPM's up seemed to bring the temperature up higher than I wished. I am toying around with the idea of purchasing a CPU liquid cooling system. My idea was that the CPU coolers come with a small radiator, micro pump, and cooling fan which a runs the cooling gel they use and I have heard it really sucks the heat. With a little tweaking with some cooling tubes possibly wrapped around the head you could bring the heat down drastically, and could be powered with a four cell rechargeable unit. The whole deal would not weigh all that much and is a fairly small set up. What do you think? Have you tried this? Is it possible? ?

Not exactly comp worthy, but here is a nitro powered crawler that actually doesn't work half bad.

Now, if you can get rid of that annoying sound.

That is a decent video and one of the most promising I have seen to date. Of course, my work PC has no sound so it was nice and quiet to me!

As for my truck, I am going to halt the production of the cooling and fuel systems and focus on making it run as an electric. I have put countless hours into the cooling reservoir and fuel tank along with their mounts, but I need to head in another direction if this thing is ever going to see the ground.

I finally picked up a radio that will be used with my steering so I can continue that and hopefully get some video of the system's operation. I have also begun the shock machining so I can post some pictures of that.

The decision to drop the nitro power for the time being is simply to allow me to see it run much sooner. My place of work may end up having its plug pulled and my shop access along with it. That would cripple my progress.

Oh well.

You could always mount a Parma Hemi engine in your electric crawler to make it more real.

lol thats a good one. I dont have a crawler period. I have a 1/8th nitro MT and thats it. I think of one wanted a gas crawler that a gas to stroke for better yet, a 4 stroke is whats needed. Nitro is to much of a race engine to me.

Just a heads up there are some people on this forum that would just as soon shoot you than allow you to make or buy,if you could find one, a nitro crawler.

Your planning to do something that has never to my knowledge been done successfully. It will have to be mostly custom built, especially the chassis. Things like which axle is best to use is something you will have to research for yourself. There are just too many goods and bads about each axle to list and we dont even know what size crawler you want to build. I would start by looking at Kyosho Mad Force and Tamiya TXT axles but you will have to make the decision based on what you find. A transmission and gear reduction are basically the same thing in RC. You need reduction and a clutch, we dont know how much reduction because its never been done.

What I'm trying to get across is that we cant definitevely answer questions like that because your pioneering. You need to research to make decisions for yourself and ask really specific questions if you want this to become a reality.

Hi guys it has been awhile and I have been pondering the nitro crawler issue and I may have found a solution to the problem. i am going to try this as soon as I get some more money. I am looking for 2 Tmaxx chassis, Tmaxx and an Emaxx transmission. I thought while playing with an Emaxx I got my mother who is in a wheel chair from an automobile accident in Hawaii why not use both the Emaxx and the Tmaxx trannies. I have decided to try and mount the Emaxx transmission up first  since it  is 2 speed shiftable Hi and low range this would be like a transfer case and then mount the Tmaxx transmission next since it has shiftable reverse. I would set the Tmaxx transmission like it is foc'd forward only conversion by locking the gears so it would go without jerkiness and when shifted into reverse it would go  still giving you the brake on the Tmaxx tranny. The gearing is the issue I am working to figure out in both transmissions. Those are the issues I have at the moment. I believe I can set the spur gear and the clutch gear similar to an electric motor and I believe I can eliminate the slipper clutch on the Tmaxx transmission. I think I can use electric motor type gears to connect the two trannies together. I will let you know what I find out as soon as possible. my axle set up will probably be kyosho mad force axles since I think they can be 4 linked easily. I will let you know what I come upwith Laterz.

The gear reduction - Mine is 400-1 for an engine that revs 20000 - 25000rpm
I have been working on the nitro lately and have addressed the clutch and steering. The clutch is now completley custom shoes with a harder spring so it can idle nicley and the steering now has zero ackerman blocks. I will get some pics and a fresh vid up soon.

ok guys dont know if anyone is still reading this forum but i work in a machine shop so i can make many of my parts. i started with a t-maxx 2.5r ive left the front stock for now the rear is the same diff,axels, and knucklesbut removes the ifs stuff and ran 2 alluminum 1/2 in dia roads across. i mounted the 4 link to this and the shocks. i changed the trans to metal unit. added a servo on top of the rear axle for the 4 wheel steer and a switch on remote depending on if i want it to turn the same or the opposite as the front. now the for the best stuff the motor is now a 32 cc weed eater motor. the tires arefrom a 1/5 scale to helpkeep them from spinningas much. i first made this truck for pulls but it work for most of thecrawling i do. ill try toget some pictures if anyone want to see it
