I liked the ones without the bushings were the link mounts . these were the only one's i found . But they have the bushings .

Hmm, that kydex sounds just what I need.... Whats a sheet of that and some of the thin going to run me? Hopefully you charge a bit more than you usually do I don;t want to take advantage of you, buddy!

I saw those integy cranks... Maybe i will pick up a set, and have the machinist make me some stainless bushings for them... Where do you get the bac link? I had no luck finding it on the site everyone linked to, looked like that site stopped selling alot of stuff...

Ill get mine rolling soon after the new year. .. BTW what gearing are you running (pinion). I have the FOC, Ti 54 spur. I think. (smallest Ti i could find) and some 23 gear that goes in the tranny to make it a little higher geared. (havent put it all together yet still in bags) Just copied off what you all recommended. Thx

Thanks Jay, appreciate the thumbs up!

The motor mount is nice, but I had some issues with setting up my gearing with it. I think you must have the TiN 59t spur, as that was the smallest I could find. Looks like you may need a 26t pinion to get the 59t spur to mesh, the tdr mount just does not quite get close enough to the tranny to mesh the 24/59 gearing I planned to run (my homemade mount was designed just for that gearing, with little adjustment). I am currently running 24/63, as the 24t pinion is the largest I have. Bit slower than I wanted, going about 38mph with that gearing, I like mid 40's.

24/59 gearing is 2.458:1
to get the same ratio with a 63t spur I would need a 26t pinion

But a 26t pinion with the 59t spur is 2.269:1 so maybe I will try that with the 1521 1y and see if the 4500 6s lipo can keep up...

Either way I need a 26t pinion, so time to give Mike a ring... Need to check my other projects and see if I need anything else form him before I order...

With the 23t gear for the tranny you mentioned... Not sure what you mean? the swap mod for the tranny just swaps the upper and lower gears so the larger of the two is the top gear. There is a write up on the lst forum under general info or tricks, good pics of the dremel work. Good luck getting the screw off that holds the bevel gear on... My was a PITA...

Heres the speed calc, the motor must be a bit more than 1500kv as the truck is a bit faster than 36...

Differential Ratio: 3.3076923076923075
Transmission Ratio: 1.9130434782608696
Spur Tooth Count: 63
Pinion Tooth Count: 24
Total Voltage: 22.2
Motor KV: 1500
Tire Diameter (inches): 6
Tire Ballooning (inches): .1
Spur/Pinion Ratio: 2.63 : 1
Total Ratio: 16.61037 : 1
Tire Circumference (inches): 19.48 inches (494.74 mm)
Total Motor Speed: 33300 RPM
Vehicle Speed: 36.98 mph (59.4 km/h)

I also have a c50 10xl, may swap that in for some more speed... This truck will have the 1521, just want to test these hackers first!

Yup that is it, best stuff I have tried to make trays with. I even made the chassis of my crawler with it!

It will cost you shipping . If you go to lst forums . The site i linked eairler someone there can tell you . I belive the guy that makes them still goes there .

Sounds good, do you need my addy? Let me know what shipping costs and i can paypal you funds+.

I will look thru that site more and see what i can find. I was going to redesign the lst steering myself, just waint on a chassis to "play" with... I want to run one 1/4 scale servo, cheap and powerful! Plus i would like a 1/8 scale truggy style servo saver...

I had the exact same idea when i had my lst2 . But i could'nt firure out a way to make it happen .

I have a pm into the owner of the lst forums asking were you can find a bac link . I'll let you know what i find out .

I will let you know when it's ready to ship. How big were the pieces i sent you last time ?.

You da man Mike!!! Thanks!

IIRC those kydex pieces must be around a 1ft square, maybe slightly smaller. I will make the steering better, just give me time.

I bought some gps (gls) something like that ? bought from china (off ebay) they recommended on LST site, has replacable bearing in the steering link. What i need is a steering post, a stronger link metal bent thing that someone names adic or suicide or some thign use to make but doesnt seen to produce anymore

The stronger link that me & linc are talking about it what you need . it's made by a guy on lst forums called firemedic . It's called the BAC link or badd ass creations link . The bell crank's i had on mine did not have bearings or bushings . thats what was recomended .

[jayjay283]

Yes sir ! that is my final missing piece, you find them or make them let me know please.

I have a pm into the guy that makes or made them on lst forums . when i find something out i'll pass on the info . If you get his link you will have to drill out your bell crank's for the link to fit . It is thicker than stock .

[lincpimp]

Very useful info guys, many thanks to you rchippie, and have fun with the builds jj. Do you still have both trucks?

Hey Mike, do you have a bl lst, or is it still nitro? How many vehicles do you have?

[Takedown]

Linc, Im looking to order some 3/16 kydex. You think that would be thick enough to keep my batts rock solid in place?

[jayjay283]

Yes link I still have them both, kind of said I'd sell you that muggy but im a greedy girl and just hid it in my garage cabnets from the wife. 4 months later no way she will remember (yeah right) ..Ill just tell her I have 2 lsts, like she know what a transmission is.
