Would it be possible to make an electric/nitro t maxx? Like taking a maxx with a 2.5 tranny and throwing a brushless motor on top of the tranny somehow, and making room to fit an esc and a lipo or 2. I say the 2.5 tranny cuz that spot where that rubber plug is looks like it'd fit an electric motor perfectly, and it would be right on the spur gear. Oh, and having a nitro engine on it as well.

For electronics...
You could use one controller with 3 channels, 2 for throttle/brake and steering, and the third for the esc. Or just have two 2 channel controllers, for the nitro side it'd be throttle/brake and steering, and one for the electric side, steering and the esc.

I was thinkin about this just the other day and I don't see why it wouldn't work. It'd be very complicating and would cost a hell of a lot of money and take a hell of a lot of work but it sounds like a pretty cool idea. I'm probly never gonna do it cuz the cost issue. What you guys think about it?

You mean like this? Nitro Revo trans and suspension, Slayer A-arms, brushless Novak HV. 4 channel.

Here's the build thread:

Yea, just like that but with a nitro engine on it too. I guess I didn't clarify it having a brushless motor AND a nitro engine
 
I don't mean have them run at the same time. I mean, say u wanna bash electric, you run the brushless motor. Then say you wanna bash with nitro, just fire up the nitro engine. Get what I'm sayin?
 
Nifty idea. Feasible. Very complicated, but feasible. No way it could be done without many many custom made parts. Nice concept though... a FlexFuel r/c
 
You could probably do this, but you might have to consider both the brushless and the nitro touching the spur at the same time. Looks like you would have to extend the chassis a bit to accommodate for both motors. Would be sick to see it actually working though, you might even be able to make money off it if it's not already done =P.
 
If you ran a nitro clutch on your brushless motor it would work. However, that's only 1% of the job. You'd have to run a complete system to control the motor (esc, battery, etc), then you'd also have to use a completely different rx system for the nitro......unless you swapped plugs around on the rx every time. That would be a real pain, plus all the weight. It is a really cool idea though...:first_place:...kind of like a mini prius...on steroids......with 4-wheel drive and uhhh..............some other stuff.

And that's precisely why this is complicated. He would need to configure a setup such that only one motor was in synch with the drivetrain at any given time. Plus you then have your electronic issues. The way I see it, the most obvious approach would be to a utilize a transmission of sorts that could actually switch between the nitro engine and the electric motor via a transmitters 3rd channel. You would also need to configure a switch to go along with that that could change the routing of the servo signals to their appropriate destinations depending on the selected power source. This would be a really fun project. Quite complicated though.
 
God I wish I had the money to do that. It'd be so sick. I have a pretty good idea of where everything would go. I'd just have to find a way to wire eerything and I'd have to find tons of money. Not going big block, what nitro engine would be able to power all that weight? And would a mamba monster be able to power that? Would a brushless motor get ruined by being spun when the spur gear is being powered by the nitro engine? A steel spur would be a good idea along with steel drive shafts and center shafts. Robinson racing gears in the tranny, revo spec diffs. That should be able to hold up to it all. This would take a lot of planning and a lot of cash

That's where the nitro clutch on the b/l motor comes in to play. When the nitro is running the b/l clutch would just freewheel.......and vise/versa.

It would still create extra drag, but it's do-able. I would just buy one of each, most brushless rigs have a nitro counterpart.

Hmm that's a great idea, the nitro clutch. There wouldn't be too much drag if u had some really good bearing in it would there?

Buying 2 seprete rigs is boring and over rated. :P

You could mount lipos under the chassis, it would keep the cg low, and custom build metal trays to hold and protect them. Battery for the servos can go on the front shock tower and the esc could go where the original battery box goes. Could use a lighter aluminium extended chassis to lighten it up and give more space to work with.

Would it be easier to mount 2 small recievers? Like the ones from the 1/16th traxxas models? The small recievers would save space. You'd just need two channel recievers. You could get a splitter so you could have the steering servo hook into both recievers.

Lol yea, I have put some thought into this... Ok more then some. But it's not like I've went crazy with it and have drawings of all this pinned up to my bedroom walls or anything like that.... I swear, it's not like that!
 
Would be nice for when your car shuts off or runs out of gas 1 mile away. You could just flip the switch to electric and bring it back. I see major weight issues though. My t-maxx already spends a lot of time upside down. All that weight on top would flip it constantly. Maybe try it with a stadium truck instead. Slash/jato/rustler.
