The engine only has about .40 BHP, the enigne is way under rated for the maxx, but you can pull some life out of it.. How much fuel has it seen? How long has it been running like this? The better your answer, the better solution I can give!!

Default Bad acceleration on trx15 t-maxx

Hey cant be worse than mine...

Mine is also jumpy and has very little compression. Went threw a mud puttle about 2 inches deep threw water all over my truck (didnt see in in my yard i was far away ) and about 5 more minutes of driveing im stuck half way between forward and reverse. It just went out on me. Im hopeing that if I just let it sit there for a nigth it will be fine wish me luck!

Oh well my fault not the trucks (damn truck fault i swear) im just waiting for the money so i can buy a .21 conversion kit and put on that hpi .21bb engine laying around in my neighbors room. We put my ofna .25 on his savage and that thing moves now!

Default .21 Maxx's Rock!

I just love my Maxx with that extra HP! I just tried some of my airplane fuel in it today and it worked just great with about twice as much smoke coming out of the exhuast! Now I can run it for half as much as I am used to!

P.S. I have a used New Era .21 Chasiss (Blue),engine mount (Blue) and rear skid (Silver) for $30 shipped if you want it?? Or I have a Used XTM (Red) .21 kit that has the pipe,CVD's (older Maxx version),Chasiss and engine mount for $65! The XTM kit is almost new with only 10 or so tanks run time!

I will even sell you a servo cheap $6!

Snowbrules,

If you still have reverse in it, I hear that is what causes the jumpiness of the T-maxx. I don't have reverse in mine so I wouldn't really know, although I can say that it isn't jumpy when it accelerates. Bad acceleration can be due to any number of problems, so you might go into deeper detail when describing the problem, by telling us when it started, what you were doing (like did you just finish richening it up) when it started having bad acceleration. Plus, you have 1.5-2 gallons on a used TRX .15, of which you don't know how many gallons was put through it before you purchased it. Nor, do you know how it was broke in. It is very possible that you are starting to see the beginning stages of your TRX .15 dying, but before we make such assumptions we will need more information in order to help you with this.

are you sure that your friend has the 1st gen maxx and not the new maxx .

I fixed my problem... by accident doh.

I was just messing around to see if my wires were going in the little slot that is cut in the casing to the part that holds your batteries and it went into reverse. then it went back in the middle. So I played with the wires to find that the wire going to the servo to switch forward to reverse had to be real tight for some reason. So I just pulled it down around another servo so its tight and everything works fine. Sry if there are many errors but its 3a.m. here and im tired

Have you tried setting your carb back to factory settings. Most people will tell you to try that first, so do that if you haven't already, then come back and tell us what happened.

OK...I found what you are looking for. Well somewhat. It has the exploded view and the instructions below the exploded view. Click on the link below to find out the information about removing reverse. I found it by doing a search through this forum. Removing reverse shouldn't be to hard if you are mechanically inclined. I took my transmission apart a few weeks ago and didn't have any problems getting it back together.

You will have to purchase a part for forward only. Click the link below for a look.

Best of luck. If you think of anything else, remember, there is a search function near the top of the page.
