[Little chicken T-Maxx]

Rebuilt it from the ground up good lot of repairs to it watch quality videos on YouTube especially the RC help.com to help me alot rebuilt the engine from the scratch new piston and sleeve new crankcase new back plate running pretty good now but having issues when I'm driving on the road everything's okay when I get off in the grass start someone a bomb down

I'm sorry are you having the bogging down issue on asphalt or running on grass? Can you also tell us your transmission set up, gearing on both the clutchbell and spur. The kind of clutch you have. Are you running 4wheel or RWD. This will help us figure out what the issue may be.

Is a four-wheel drive with Traxxas T-Maxx Pointe 15 original clutch Bell I replace the spur gear 70 spur gear I put new belt clip shoes on last night readjusted the slipper clutch and it seemed to help song now I can pull through grass without a issue but still not climbing Hills

Does the engine struggle to get you up the hill or is it something else? Does the front get hanged up? If you want to do hill climbing you will need to adjust your suspension to the highest possible setting to help the front clear obstacles or else the front skid will dig into the obstacle and get hanged up. Also knowing your transmission shift point is critical to clear a hill. If you are on the lower gear and don't have enough speed when climbing you will not clear it plus your engine since your engine does not have enough torque and speed to begin with. Your tires can be a factor as well since traction plays a big role to clear the hill(also maybe the hill you're trying i clear may be just too big). There are a lot of factors that you will need to consider and need to learn to tune for. 1. Your carb settings need to be at optimum. 2. Your 2 speed transmission points need to be adjusted according to the conditions. 3. Your slipper clutch need to be adjusted accordingly. 4. Your suspension need to be dialed in for the condition. 5. Need to use the proper tires for what your driving conditions are. 6. Need to figure out the correct gearing for the conditions you are driving in. 7. Your differentials need to be sorted out(assuming you have the stock diffs on your truck which is not sealed this is a lil tricky. I can only advise getting the thickest diff grease that you can and pack them. Since it's not sealed it will still leak and dry out so you will need to rebuild much more often than the sealed ones. 8. Your engine is not suitable for what you are attempting.(I have a 3.3 with a Os 21TM motor and I still struggle clearing the biggest hills at my local BMX track due to my gearing). I'm including a link to the TMaxx performance guide. Though it applies more to racing and set up for a race track it will help you get the basics for tuning. The link is for part 3 of the guideline but there are links on there for the other parts as well. There are also How To articles in this forum that may help you as well.

Could have been the grass was wet today

 

[DXtreme1]

Yes that would be a big factor. You would have less traction and the grass would hang up on your tires and undercarriages depending on how tall and thick the grass is and how low your truck is. If you are climbing a steep hill don't take it straight up. Climb it on an angle to make it easier for your truck to get a climbing start. Are you still using the semi paddle tires on your truck? I recommend using the buggy style treads for better traction for most driving surfaces when you get the chance or mod the tires but you'll need a grinding or sanding tip and a Dremel tool to do this. Also it's really messy to do.

On the chassis under the clutch Bell there is black dust powder

Waiting for my air filter mod to dry I was had to reduce her inside the air filter base to fit my carburetor

Need some help tuning my T-Maxx

The T-maxx .15 trying to figure out the idle little bit High still have an issue with a slipper clutch

Bad news yesterday no one bearing locked up the easy start module backed off the motor and the one way bearing was stuck in the gear

If you don't care about the ez Start might be a good time to switch to pull start. I still use mine because of the body I run but if it wasn't for the body I would have ditched it already.

 

[Little chicken T-Maxx]

I'm going to order number one line bearing

 

[DXtreme1]

Just make sure you do routine maintenance in the one way bearing so they last longer. You can also do the Ez Start mod so it makes it easier and faster for you to clean the bearing and oil it

How to mod it

How do you mod easy start

 

[DXtreme1]

Drill a hole on the center where the TRX logo is. Then in the bottom of the ez Start housing. Center hole is for you to spray Nitro cleaner to clean and the bottom hole is for drainage. When nitro cleaner is dry use the center hole to spray lubricant like wd40. I don't have the mod done since I take apart my TMaxx trucks often for inspection and maintenance including rebuild if I think it's necessary. If I personally did the mod though I would go one step up in regards to the center hole. I would put in a brass or aluminum fitting and run fuel tubing to it. It will make the center hole easier to access and I can cap the end off to seal it.

 

[Little chicken T-Maxx]

Did the easy start mod did the center hole first for the extra nipple from a tank on it have to make the drain holes now

 

[DXtreme1]

Looks good so far. The metal fitting how did you secure it? You can put a dab of JB Weld(make sure it's not quick weld). That's what I used on my pipe to secure the brass fitting for the pressure line.

 

[Little chicken T-Maxx]

I used water wheel putty it comes in a in a 5 inch tube with both parts of the epoxy during the same two you just cut off the how much you need oh you work at 2 it starts warming up and changing color

I used Underwater World by JB Weld

 

[DXtreme1]

I think ur set here. U could probably add a fitting on the bottom as well and install fuel tubing with the length you need to drain it in an open area so it don't drain into the chassis.

 

[Little chicken T-Maxx]

Don't have no more fittings only had one
