I know that these MT's have a weekwacker motor in them. having said that, could you take a weekwacker engine out of a weekwacker and use it? I'm just curious to see if you can do it.

Unless the weedwacker uses the same engine you find in your RC, you will need to fabricate all of the attachments necessary (clutch housing, engine mount and or braces). There will be too much involve to make it worth it in my opinion (there are so many engines available that are straight drop in).

There was this guy in YT and he was able to slap a weedwacker engine, it was very depressing to watch.

The guy swore he had achieved the greatest thing ever, doing 5mph laps in his driveway. It steered like a school bus and stiff as a on-road car. The only thing to make it great was to change the title to, my 7th grade project and have a kid driving it, then maybe the video had some hope w a shower of thumbs up, but that was not the case.

Ya I thought that it wouldn't be too easy. Lol. I'm pretty sure that I have the first gen MT because it's like 8 years old. Mine has the 23cc engine in it. Down the road I might put the 32cc engine in it.

That drivetrain must be new with such a small engine.
Wow still have that 23 on that truck.

It will be night and day from a 23 to a 32 full crank engine w a pipe, some minor port work and a 8k clutch spring, to unleash all that power.

Well i forgot to mention that it does have a upgraded air filter and muffler.

Interesting to hear from someone having the truck for such considerable time.

So, what things continuously break, or every so often?
Its weak point and what have you done to make the truck bash proof?

(or lets say, at least reliable to run a few tanks and have some fun...)

Well, I just got it from a friend who had it sitting in his room for that long. When he first got it he crashed it a couple times. He never run it after that because he was scared to break it again. Lol. But I've driven it a few times and only broke the upper suspension arm. ( from crashing into a tree) but if something breaks I'm replacing the plastic parts with the aluminum ones.

I just don't see a 23cc motor being able to move the MT very well lol I got a V3 MT last week, I broke in the 32cc motor really well, tuned it, and it has some impressive performance entirely stock but I'm looking forward to installing a tuned pipe on it, from the videos the tuned pipe gives it damn near close to double the power

I was given a 2WD Dunerunner with a 25cc CY in it a while back.
No idea how old it is but it had been in the guys lawn locker for 5 years.
Before that hid grandkids used to play with it.
Still had the stock can on it when I got it.
Put a new carby and a KM Ghost pipe that I had laying around and it flies.
Surprised me.
You can see it running here.

Nice but you keep tunnining it pegged wide open like that and it ain’t gonna keep runnin lol,I believe the cy motors are better than the hy if someone disagrees please let me know why as I also am still learning thanks but you have slot of work to do on that mt,I would put a 320 zenoah in it with a ddm or jet pro exhaust ,Baja wheel adapters and different wheels and tires cause your gonna have issues with yours it’s just a matter of time for how old it is and upgrade your set is then whatever breaks from there replace it with a brand new stout part

Thanks for the advice but this isn't my first 1/5
CY and HY are both crap that's why I run Zenoah in my other car.
This one is just something to muck around with.
BTW You don't have to pay big money for wheel adaptors.
King Motor and Rovan wheel hexes fit straight on MT , TT and DR axles and are about $3 each.

I got ya man didn’t mean any disrespect ,I didn’t know you had other 1/5 scales ,I was just tryin to help and ya I know the hey and cry are crap that’s why I said I would put a zenoah in it but I was just curious if the cy was better then the hy because I’ve heard that a bunch of times but have always wondered cause in my 1st truck the xt I have I put every power upgrade you could on it and I beat the shit out of it and it still runs strong and has the stock 30cc hy ,I think they are just hit or miss but I’m just waiting for it to go so I can throw a zenoah in it,and the wheel adapters,I have to get them for my XT,can I still get them that cheap?thanks for any help and once I’m done with mine I’ll throw up some pics ,I found a guy in California that makes complete cages for the XT’s I mean like he will make it look like a full cage like they run on those buggy’s with the big bores in them and I love that look and I could never find anyone who made them ,I was about to buy a little stick welder and make my own but he’s gonna make them and start producing them ,and after the xt he said he would work on the mt and so on,he will make 3 versions one to fit my truck with a side pipe,one for people with stock exhaust and one with people who have a rear exit like a jet pro which is freakin awesome but as soon as mine is done I’m gonna paint or prob powder coat it then I’ll post pics and his info,sorry for the book I wrote, lol
