It's the hardened spur gears big flat landings on power they still snap some teeth off cause of chassis flex I think is what he is talking about.

And yes they were the new ones as he brought from Coast2coastrc which we had the latest from factory.

The part number is TKR5415B, the 2 I stripped one was from coast2coast and the other one was from TEKNORC in the states. The spur gears wear very well but they just can't handle on power flat landings. Went out today did exactly the same jump with the new setup and no problems.

Unfortunatley I've had the same problem with the new spur grear. I purchased the revised spur gear from Coasttocoastrc about 2 weeks ago.
I used it at one club race meeting and this is the end result. This is at the same track Drew races at.
I've used my Serpent centre diff with Serpent spur gear and it's been bullet proof for about 3 club weekends and a state title.
I think the main issue is the narowness of the Tekno spur and the flex of the chassis. The Serpent spur is wider and that seems to help imo.

Hey Drews and XT8, sorry to hear about your issues with the spur gear, please email [email protected] with those pictures and the details you provided. They will be more than happy to help get you guys squared away and will also help them possibly identify the problem.

by the way, what chassis braces are you guys running? Center and both rears or Center and left rear or center and right rear, etc...?

Thanks for the feedback guys. We'll keep an eye out on this issue and see if we can make them better. There is a track here in the states with big flat landings and some racers there have had a couple issues. For most conditions however, we haven't seen any issues since the new gears came out.

Hi Grahamn I use both rear braces and I'm pretty sure Drews runs both as well.

Thanks TeknoRC I'll email those pics to you.

Hi Graham I run all 3 braces.

The new spur gears are a lot better than the old wear wise just seems to be a problem strength wise under load and flex combined.

Hello everyone, thank you for your patience while we look into this. Can you guys provide info on the agama spur or other spur gears you are using? Specifically interested in the thickness.

In the mean time we think the issue is due to chassis flex under hard flat landing or casing a jump. Please be sure to set your mesh as close as possible without the teeth actually bottoming out in the opposing gear. When setting the mesh this close with new spur and bell the mesh will sound noisy. Please run it for one tank and the gears will break in and be quiet. To this point I have not broken a single spur when setting the mesh as I mentioned.

Thank you and happy holidays.

Has anyone figure out what items will it take to make a ET a NT? Is it worth it? TIA

My suggestion would be to buy a serpent,and agama Spurs and make a copy to fit the truggy.That would solve the problem.I have bought a serpent complete diff and shimmed it to fit,problem solved for me.i have expressed this to you guys at Tenko the times I have talked with you about problems.( Spurs and rear diff case were the bearing fits sloppy.you can move pinion up and down with all new parts. ) Just my two cents!

I asked if an alternate flywheel and clutch setup would work on this truggy and someone said they were using the m2c 34 mm four shoe clutch. Also wondering if u can use a normal bell such as mugen or agama on this truggy or if u had to use the tekno specific flywheel? Nothing wrong with the tekno setup I just have other truggies and I move my engines around a lot and would like to just swap engines without having to tear the clutch and clutch bell off to put on the tekno

The only way you can use another clutch bell is to shim the flywheel, as the tekno clutch bell is a lot longer than a standard clutch bell, in my experience the mugen clutch bell probably gets the closest length as it is long as well but still needs to be shimmed, just not as much as say a kyosho bell, either way if your moving your engines around you will still have to dismantle it in order to shim it to get the required mesh.

I use the m2c clutch and on my backup engine I have the Werks clutch. I use the Tekno clutch bell or Serpent clutch bell.
I have just fitted the vented Serpent clutch bell to try out. But to use a standard size clutch bell you'd have to shim the flywheel too far forward.

Ok thanks for the help. I should be able to use the m2c or a three shoe setup though as long as I use the tekno bell?

Correct.:nod:

Thanks. That's easy enough. Just didn't wanna change the entire clutch setup just to swap an engine

help
 

hi guys any insight?

I myself have held off running the tekno centre diff and clutch bell set on my 3 tekno cars but before Christmas i purchased a number of revised centre spurs and fitted one to the truggy and headed to the track, three tanks in to the practice session i to landed on the flat over shooting a jump and was on power trying to pull myself around a 180 turn and that sound every rc racer hates to hear started to ring out, yep you bet teeth missing from the revised spur gear ( $42 AUD lesson learned )

So for me its back in with the complete shimmed xray centre diff set up on my tekno cars that worked perfect for the 4 day state titles, club day after club day, I have three stock spur gears that came with each kit and another 2 revised spur gears sitting in my pit bag if any one needs spares at any events across Australia.

Its a shame as the truggy is the best i have ever driven and im not a fan of using non factory parts on the cars im driving but until this proplem is solved completely where people can just run the product with any issues at all these parts will just sit idle in the spare parts bags.

On a positive note here is my club car truggy ready for action in the new year.

I guess cheapest and most efficient way is TKR5400 ;)

I would guess Tekno is not hearing us!I understand engineers are telling them one thing,but engineers think that the way they do it is best.Maybe Tekno should find some new engineers.lol.

:weird: :weird: :weird:

That's sweet!

Spent all day today testing the new agama diff set up, and the truggy ran flawlessly all day, didn't miss a beat, no diff leaks and no stripped spur gears.
Looking forward to the new season with my new ride .
Even with the spur gear problem which really isn't that big of a deal especially now i don't need to worry about it, this truggy is still by far the best truggy i have ever owned hands down it has the best quality, durability, speed and handling of anything out there, GOTTA LOVE TEKNO.:nod::nod::nod:

Drive shaft pins
 

Folks
I understand the front and rear drive shafts are not very expensive to buy. But is replacing the pins a reasonable option? If so which maker's pins work?

Secondly, I see aluminum drive shafts are an option. Is aluminum strong enough and durable enough?

Thank you

I use the Mugen ones

Looking pretty sporty Sam!

I just replaced my center drive shaft pins with some Serpent 3x14mm pins I had left over from my 811T.
I personally wouldn't waste my money on the aluminium center drive shafts.
With the amount of chassis flex you get from this truck I reckon they would bend too easily.

Got to look after the club car too, keeps the major event car fresh for the big ones, time for some more painting i think, have a great new year Hamm

Thanks buddy

Tekno NT-48's placed 1st, 2nd, 3rd and 4th in a full truggy main at Fear Farm track in Phoenix yesterday. These things are incredible driving machines. Want to pass somebody, push them into the corner fast and cut in sharp and your gone. Love it !!!!!!!!!!!!!!!!!

Shhhhh don't tell anyone haha.... Soon everyone will have one haha!

Do you have a setup for Fear Farm?

I drove my NB this weekend, im toying with the idea of a NT!

Do it. Truggy is so much fun to drive.

I only drove buggy for many years but since I got the NT I love driving truggy now.

Buy one you won't be disappointed !!!!!!!!!!!!

Agama body is a borderline drop fit. All I did was reverse the front posts and shave off the round part at the bottom. Only thing was the raudio tray rubs a little. But that an easy fix with some shoo goo and lexan. The stock body for me was breaking at the front of the side windows, all the to the bottom. The front tower also rubs. Agama body eliminates all that.

Looks nice.
