Thanks Ernie, will go do some Youtube fishing

Great thread ernie! Beautiful work on the weights. Don't even own one of these trucks but I'm sucked into this thread. Keep it up.

I just wanted to comment on a action a moderator took on here just recently.
A member had started a thread about sharing info for building up grades for the TRX-4, which I think was a great thread! Very informative and he has some great ideas as well as the ideas of those who shared their info. Well, it was removed because the person broke the rules about mentioning sales of a product in his thread. Should the whole thread have been deleted, in my opinion I don't think so, but it was. In all fairness to the few mods that donate their time to trying to keep this site running smooth, rules are rules. The way this person worded his post was a indication that he knew he was crossing a very thin line, and at the time I thought he shouldn't have done that!
So a word of advise for those who have a product that maybe would help your TRX-4 buddies, buy a venders star! $100 is not a bad deal. I'm retired, I don't have a venders store on here, so my products here and in the ascender section are sold by word of mouth advertisement. In the last two years I have paid for my blue star 300 fold just with 4 or 5 products.
Having said that I hope the mods will see fit to restore the portion of the thread that wasn't breaking the rules, it was very helpful!

It used to be worse , I was selling my winches threw a Vendor on here and ran into problems just answering questions , But I agree with the rules . Buy a star and sell ,,aint that hard.

So I've had a chance to run the portal weights for a while now along with the SSD d-hole wheels that clear them. The wheels they replaced were quite a bit heavier (2 lbs for all 4), but I had gotten to a point where I'd added all the weight it needed or a bit too much maybe. So the lighter wheels along with sticking weight where its needed was a welcome improvement, I'm quite pleased with its performance.

Yeah I was in denial of the laws of physics a bit, though it is an easy way to add weight down low.

Codyboy,any issues with gear mesh? Mine is either too tight or too loose with 9,10,or 11T.Not trying to monkey up your awesome thread,but I wanted to get it out there for maximum feedback. Thought you might could recommend a talented machinist to fab us an alloy motor plate. I know your plate is full,but ......jus sayin' . I don't see needing any adjustment above an 11T,as top speed has never been lacking lol. Your thoughts please

I hear your concerns, I'm running a HH Stubby 2700 puller with a 9 tooth and it seams to be working fine. No heat problems, so I haven't given it much thought. I could give it a little time and thought and see what I could come up with. NO promises!
I'm headed up to see a friend tomorrow, (Kelly Lunsford owner of Lunsford Titanium) to run some ideas by him on my weights. I will draw something up and see what he thinks. My problem is not having the right tools to a large production run and most drivers on here aren't willing to pay the price for quality products. All they see is the price and don't consider at all the time venders put into the design of parts. Because of the Chinese market the sale of my weights have dropped way off. I think the biggest problem for new design on here is that people aren't loyal to the venders dedication to try and come up with design for a small market. For me being retired, I'm not relying on my parts to make a living, but some are! And our time is money, or time away from family!
OK, off my soap box, I'll see what I can come up with.

Agreed and thank you. Sick of working on this or servos constantly. I don't mind paying top$ for top quality-you get what you pay for. Safe travels

So my conclusion on designing a new motor mount is that it is above my shop capabilities. What I'm thinking is to order another motor mount and very carefully open up a slot between the a and b holes (or b and c) on each screw and then see how the motor will hold it's adjustment on the mount.
For someone who has a CNC or mill it would be a lot easier for them to build.
Sorry, best my little pea brain can do.

Sounds good Codyboy. I've shelved the trx 4 for a while till the after market eeks out a few parts. Went back to work on the 10.2 .The Traxxas is a donor vehicle for now

[Mountainsofbeer]

Are you guys shredding spurs or what should I be looking out for with motor twist? My gears look pretty good so far I have to say not much wear at all

[Inspector86]

I have had zero trouble with the pinion and spur gear. I went to a 9 tooth pinion and installed a HR aluminum mount plate. No issues with the motor moving and gear mesh is just about perfect.

[CODYBOY]

Ok guys, I have a few more pair of weights ready to go down the road.

And doing some rear weights now. These are now made of five stackable discs that can be added or remove to counter your weight bias. Less see if china will copy this one!

[clm]

Man, I would love some of those but money is just not their right now. Still paying off the TRX and saving for a new servo. They are quite nice looking!
