Good work. It looks like it fits perfectly. You might be better than me at this cutting and shaping business! :wink:

Well, today I went to my first puller competition and I did pretty good for the first outing.

I was in the 7lb class and they start out at 100lbs with a pull off to break the tie at 120lbs. I only missed a full pull by just over three feet all three pulls so it ran consistently. I did try a air pressure change on my last pull and did about the same as the previous two runs.

Adjustments for me will be to raise the hitch to exactly 2" mark, and a pinion adjustment. I am running a 16t pinion now and need some more wheel speed. ESC is a SV2 with a 4600kv motor. Not sure if I should go up or down at this point. Weight came in at 7lbs exactly the way it sits.

Over all I can't complain on not getting a full pull but man was I close and the guys and gals (Yes, there were two gals that ran trucks as well) thought it was great considering never pulling before.

Their were some really sweet trucks there today and mine looks as though it is way out it's league.

I took a lot of photo's but if you want to take a look here is a link to my PB page. I took a couple videos too. I will post those soon.

Looks like you had a lot of fun. Lots of great trucks, I really like the Ford 4x4 puller. :)

That truck was sweet! Unfortunately he busted a hardened pinion and output shaft on his first pull! It takes a lot to twist a hardened pinion, it was in tiny little pieces. It was really bizarre. He normally runs on dirt and was getting to much traction on the carpet.

Ok experts, any ideas on which way I should go to accomplish a full pull? Pinion change up or down? I already know I need to adjust the hitch height. I think I have the weight set to where it needs to be.

when you coming to the end of the pull does the rig seem like it still has the power to gear it up or down?

No, when it gets to the end it looses speed and just stalls out and the tires spin slower. It does not even pull the front end up at all towards the end of the pull.

I am thinking if I can get more speed to carry it further in the run it will make a full pull early on.

Moving the hitch forward too... Will get that front end up.

I wouldn't do too many changed at once because you need to see what affects what.

I'm not going to move the hitch forward. I need it at 2" exactly. When I ran it is sitting 1 1/2".

I am going to make a pinion change and see what happens this Sunday. Problem is my motor mount is not ideal for quick changes and requires a lot of turning wrenches to change up or down. I need to make a new bracket so I can pivot the motor to adjust pinions on the fly.

Weight is going to stay where it is at. Biggest move for me now is a pinion change.
