Welcome to the EB410 Wiki page.

Basic Stats/Features:


Shaft drive (tapered AL for light weight and straightness)
Gear differentials (all 3)
Low Angle CVAs (with captured pins so no ejecting them!)
Durable stub axles with 12mm hexes and optional offset adjustments
Reverse bellcrank steering system
Quick access bulkheads (for easy diff maintenance and tuning)
Spllt center diff holder (for easy diff maintenance and tuning)
CNC milled chassis
CNC milled adjustable hinge pin braces
8th scale style motor mount (for easy mesh adjustment)
13mm big bore shocks
3.5mm shock shafts
No EClips
Droop screws

Instruction Manual

EB410 Resources

Electronics requirements:

Shorty battery
Servo (low profile OR full size will both work, low profile will have lower CG)
Motor
ESC (Wiring: shortest possible with the ESC directly at back of motor)
Receiver


Additional things we know:

Works out of the box for mod or 13.5. Start mod gearing around 21t pinion, start 13.5 gearing around 29t pinion. Additional smaller spur gear(s) will also be made available.

Internal Gear Ratio: 2.5:1
For comparison:
B64 is 2.47:1
22-4 is 2.4:1
YZ4 is 2.6:1

Wheels

B6/22/rb6 wheels direct fit
22-4 front wheels direct fit
B64 front wheels will fit, but you need the +1 hexes (can use #TKR1654X, which is a +1mm hex)
22 2wd front wheels will also fit, possibly a good option for carpet.


Tips and Tricks

List of Vehicle Setup Adjustments and Build Tips can be found here. There are several videos and articles detailing the building of shocks, diffs, camber links, etc.

Setup Sheets:
Setup sheets for all Tekno RC vehicles can be found here. Please be sure to try our recommended setup. It works very well on most tracks.

Warranty Policy:

Tekno RC is the only company in the industry that will give 50% off of parts if returned to them using the General Warranty return policy found on their website. The parts can be lightly used or completely abused, as long as the part is still being produced it's covered!

Piston Drills:

Some of our setups recommend using pistons that are enlarged. For instance 4x1.9 or 3x2.0. To drill the pistons we recommend the following:
GMK Supply Piston Drill Set
16PC Metric Bit Set Metric Sizes 2.00 to 3.00 MM.

Does anyone know what the total thickness is of the hexes needed to run associated wheels? I know there +1 from the stock but I'm looking for total thickness. I have an extra set of tekno 12mm hexes that measure 4.66mm thick im trying to find out if these will work with associated wheels since I have a bunch or if I need to order +1 mm hexes still.

I think they are 6mm

I'll check tomorrow to see.

I tested a spool in 13.5 and various heavy weights in the center diff. The spool had the potential to lay down the single fastest lap, but wasn't as consistent lap to lap. It also didn't land jumps as well. You had to be very precise while driving it. Same thing with heavy diff oils but to a lesser extent.

I can see a slipper for carpet/turf tracks, but honestly the center diff is so much more forgiving I think it's benefits outweigh the slippers benefits, especially if the slipper isn't that much lighter. If the slipper were lighter and also slipped the front and rear independently then I can see using one, but otherwise I'm always going to run a diff.

Any chance you measured the difference in reduced weight?
Also curious if a spool will be an available option or if you can share where you got the spool, was it custom made or pulled off a random TC chassis somewhere?

I've grown used to running a spool on my K2 and would like to compare some lap times as well when I get my EB410 put together for our local turf track

I demand a one way adjustable clicker with slipper and diff action built in alongside overdrive to one end that is activated on my 3rd channel. Hop to it.

PS. Must be lighter than the stock diff or else.

I had an Sworkz EK1 and it was great on low bite with the proper spring and shock package. I doubt this car will struggle on low bite...

I'm kinda torn guys. I'm going to run 13.5 and I'm sure it'd help a bit, but do you guys think it's worth it to put together a full ceramic kit for this before I build it? Or maybe recommendations on which bearings to keep rubber sealed and which to run ceramic? I've only ever done ceramic in transmissions for 2wd's before.

I like to run AVID revolution ceramics with a steel race on only 1 side and leave the rubber seal removed on the opposite side, then flush the stock grease and run a dry teflon based lube typically used for bike chains. They have a kit for all the drive line bearings minus the steering linkage bearings here called "The Essentials":
Tekno EB410 | Essentials Bearing Kit

AVID also started carrying a new "Aura" bearing which is the next generation after the Revolution series which offers even better performance with a slick nylon race, but requires less abrasive cleaning chemicals and needs to be serviced more frequently so I opted to stay with Revolution for now, but might consider Aura next time:
10x15 Bearing 10x15x4 Ceramic Single Metal | Aura Bearing 6700ZC/3S

Excellent info! Thanks man . Just to clarify, you leave the rubber seal off even while racing? Or is it just to clean out the bearing, then you put it back in?

Kinda nice too that they have the drop down menu to make your own kit. That was some quick work lol. I didn't think anyone but that JT company had made something for the 410 already

AVID had these kits ready for the EB410 the same day Tekno published their bearing chart

Yes, I leave the rubber shield permanently removed and face that side to inside of each hub/diff leaving the metal shield exposed to the elements. I typically remove/clean/lube the Revolution bearings once every 4-5 race days but I think the Aura series needs to be cleaned every 1-2 race days and I'm not sure if I'm THAT dedicated

Thanks for clearing that up

lol yeah I think I'll pass on the Aura's as well. Just the price alone is like getting slapped in the face.
