We wouldn't do an ET410 to ET410.2 upgrade kit, we'd just release a .2 kit. Same thing for SC, we would just release a whole kit. I agree it would be a nice option to have though.
Most rc companies don't do "upgrade" or "update" kits anymore. Unfortunately they don't sell well, most customers just buy the newer kit. And the ones that don't buy the new kit either upgrade as their parts wear out or buy one or two items they think are most necessary. If it were financially feasible I'm sure we (as well as other companies) would do it.

I purchased the ProStar ET410 2WD SCT conversion kit and while I liked the chassis and the options it afforded me, I was disappointed with several features: NO tabs for the rear droop screws; the failure to notify customers that the rear shock forward modification was required for this kit to work; and the lack of instructions/patterns/templates for modifying and mounting the recommended option parts needed for the SCT body mounts and the front/rear bumpers (as well as additional parts that would be needed such as the size of longer screws etc.). I did send an email to ProStar detailing these concerns hoping they would remedy them in future kit releases or chassis upgrades - so far no response. I’m going to post a series here describing what I did to fix some of the most frustrating modifications WITH TEKNO PARTS to make this a SCT conversion. If there is interest, I’ll post more details on each modification with pictures.

Totally frustrates with trying to figure out what to do with the ProStar recommended Associated rear bumper kit I purchased when I ordered the chassis, a friend sent me a picture of how his Cobra 2WD chassis (forerunner to the ProStar) was built for him. Very much different than what is shown in the ProStar website but still extremely weak and fragile appearing with only a single attachment point (two screws to the shock tower). So being a TEKNO purist, I took the rear bumper off a SCT410 and played with it to see how it would fit AND IT DID! Only required one modification and two longer screws. The holes holding the D brace on the ET410 are spaced closer together (about ½ the width of a screw) than on the SCT410, so I had to redrill those holes on the bumper to allow for this – it was more like I augured out the hole to make the gap narrower). Once this was done the bumper was a direct bolt on two longer screw into the D brace and two screws into the shock tower; and is as strong as the SCT410 bumper on a SCT410. I do recommend you disconnect the shocks and remove the wheels - it makes it easier to put the screws into the D brace without the A arms coming out and those little spacer going all over the place. Now I won't be afraid the bumper will break if a corner marshal picks the truck up by the rear bumper - its TEKNO STRONG!

So what the heck, what about the front bumper? I had a spare SCT410.3 bumper so I played with it and I ended up with a hybrid, the AE top plate (from the recommended AE front bumper kit I ordered with the Kit) and the Tekno bumper. The Tekno bumper was bent to the correct angle (in contract to the AE bumper that needed to be heated and bent into the correct angle) and only needed to have holes drilled for the ET410 gearbox. I used the spare ET410 chassis as a template and jig mounted the bumper to it for drilling. Be sure to leave a gap between the bumper and front of the chassis for the ET410 A brace as it extends beyond the front of the chassis (I didn't and ended up having to Dremel the bumper to make it fit). Mating the AE top plate and the Tekno bumper was the only tricky part, but that was overcome so I could use the AE top plate as a jig to drill two holes through the Tekno bumper. Now with two long screws securing the two pieces together, I now have a mostly Tekno front bumper as well.

I had the ProStar recommended optional SCT410.3 body mounts. However, these required extensive modification with my dremel to fit the ET410 Kevlar shock towers. The pictures my friend sent me showed different body mounts – most likely Associated ones. They looked to be a direct fit on the rear and requiring less modification on the front. I’d check with ProStar and find out what these are and purchase those body mounts, unless you are a Tekno purist. But the SCT410.3 body mounts do work but the rear mounts after modification end up slightly wider spaced than the stock ones. With the Silverado Truck body I use for SCT, I will have to be creative to find a way to secure that body with a body clips - but its doable. However, wider spacing between the rear body mounts may not work with your style SCT body.

Any rumors about an et410.1 or .2?

Tower is showing “temporarily unavailable”, amain doesn’t even have the kit on their site, and some sites that usually show ETAs are showing no dates.

What’s the skinny?

The ET48.3 is the same way. On tower no Nt48.3 or ET48.3 is listed any more. I've been waiting for the ET410 for my daughter.

Late June has come and gone.....

This was posted in a FB group page. Seems legit from Tekno. Maybe(hopefully) a 410.2?

et410.2/sct410.2 Kit! Ok, only dreaming out loud. But why not put the eb410.2, ABCD Blocks in, 3.5 pins, truggy swingarms they already make for the 3.5 pins, and a couple more little updates. Probably cost less then going back and making old parts. Lets hope they do a bit more than that. Reinforced rear bulkhead at the least. But I sure would love to see a SCT chassis, body mounts and bumper kit.

Anyone else use this exotek piece? I added the updated front bullhead saver from exotek and added this rear piece but it pushes the tower back ~3mm. Any help here would be appreciated.

I did a bit of grinding on the wing mount, then longer nuts/bolts all the way through.

I'm ready for the ET410.2 to make its debut. I hope Tekno keeps the ET410 platform around for many years to come. I know I can't be in this hobby without one. To me it's the best thing that happened to the 1/10 scale RC world.

Best thing that happened to the 1/10 scale rc world? Well, if they include, which I bet they will, 3.5 hing pins and a rear bulkhead support, it will be a very Durable car. I like my truggy. But I feel it did hurt 4x4 shortbus. There is nothing like 10 4x4 short buses with stupid power, all hitting a jump balls out. Big bummers and rubbing is racing. But the Truggies are fun to. I have both.
