Default Jato won't do wheelies.

I tightened the clutch to max, brakes are set up so at idle there are no brakes, suspension is on max hardness. I haven't tuned the engine fully yet, because it runs extremely hot, seeing as it's 40c ambient, however accelration isn't a problem really.

It will do a wheel for a second if I hit a bump or something

Thoughts on this? Maybe just need low speed leaner?

If it is extremely hot then it is probably too lean already and starving you of power by lean bogging.

That shouldn't be an issue. It's pretty much at stock, with the low speed turned in a tiny bit.

Might try softer rear suspension? Let the weight transfer back? When I used to race my Jato it would wheelie without problems. Happened mostly when it shifted into 2nd on the straights. Could be the motor just needs to get broke in completely. 3.3 in that thing is crazy really.

Ok, I'll give it a go in the morning (9.40pm here).

Any other tips?

Add weight in the back. How hot is the motor? Do you have someone who is knowlegable to help you tune?

I don't want to sounds like you don't know what you are doing, but are you sure the Slide on the carb is opening up all the way? Might need to adjust the EPA..?

Make sure you are getting traction and if you are it has to be your tune..... i have had several jatos and if the slipper is tightened all the way you should be able to flip backwards.

Its the tune on the engine, plain and simple. It has to be tuned properly or else it won't produce the power needed. Get it tuned and you'll be back in here asking how to keep the wheels on the ground

Well originally the engine was burning hot after like 2 minutes. I found out the couple between the exhaust and manifold had split, and so smoke was pouring out. After replacing it, it runs a fair bit cooler, and better.

I'm running basically a new set of the Traxxas Anacondas. It does slide a fair bit on loose dirt, but seems to grip alright on the road. The carb opens all the way up. What's EPA?

Brb, going to test soft shocks.

EPA is the End Point Adjustment. A setting on most radios to make sure the servo is traveling the proper distance. Is your clutch good? Maybe it's slipping..Like a few others have said, that thing should be on it's lid more than it's tires unless you have the wheelie bar on it..

Haha, I was testing it, and decided to loosen the clutch, and yeah, the clutch must be dead beyond believe. It is a second hand car (with a fair bit replaced), so I hadn't tested everything.

At tightest, it runs legit, no wheelies, floors it, goes awesome, tires do some awesome balooning (would some glue made for assembling models etc be alright to use on them?).

I loosened it a bit, and it didn't improve anything, and after 3-4 minutes, I stopped, and the clutch was smoking. I loosened it a bit more, and the car wouldn't move lol.

New clutch plate I suppose lol. Is the stock Traxxas one fine? Or would an after market be better? Also, my spur gear has a chip, and I may as well replace it, should I get a steel one?

Nope stay away from steel, it just transfers the stress to another part which is harder to get to and not as easily replaced. With proper mesh you won't have any issues with chipped teeth. Plastic is your friend, it flex's.
