Definitely not cast. That's what 7075 looks like when torn apart. Sorry to hear about the crash .

Picked up the tekno specific servo horn, sucks it rubs the body but definitely seems it'd be less stress on the servo. Just had my painter do a fresh body and it scratched after the first run. I'll have to pick up a JC body as it seems to have more clearance in the servo arm and linkage area, next go round. Tekno may wanna add a bigger bump in the body there going forward.

Those oils are fine in the buggy, ive run them. 5/7/3 was stock oils for the .1. Now, for me the 410 ran a lot better with thicker diff oils, like 7/7/5, or 10/10/5

Get a shorter screw and a thin lock nut that should take care of the issues.

Yes, I reported rubbing with the HB servo horn after my build, but it was due to the quite long original screw. A 2mm shorter screw and problem solved. I used the same nut as before.

So, I did some quick weight measurements (some parts in bags from store wall).
In short, it looks like using the actual eb48 arms/shafts on the outside of the car vs the sct ones will end up about 56g heavier than the sct versions, though some of that should be offset by the larger 17mm hex conversion stubs axles and wheel nuts(which I didn't have access to to compare to the real eb48 ones). So, I'm going to say aprox 50g difference. The big one would be the chassis, of course, which the eb48 already has vs the truck, and is a 66g difference, and why the eb48 is actually no heavier than the truck (mine is actually lighter than my 410 until I put batteries in, despite the heavier T8 motor). Knowing this, I'm now more inclined to do the ebuggy lite thing, but from my spare eb48, rather than from a truck, keeping the eb48 arms and such in the process for durability as the chassis already offsets all that weight.

Has anybody else tried this yet? Does anybody (especially Tekno) have more accurate figures on weight for me, or thoughts I'm missing? My biggest concern would be heat, as I've yet to see a 2s ebuggy that doesn't have heat problems, though they haven't been teknos thus far.

Has anybody tried the Tekno ebuggy light yet with the hobbywing sct motor that many seem to like?

So you are saying that the buggy is lighter than the sc?

I known my buggy is on the light side because the electronics I use.

My buggy, set up for 4s and with only lightweight hexes and center driveshaft and the heavier al rear diff mount is lighter than my sc with cf servo holder, cf towers, and the center driveshaft. My buggy is not a .2 so doesnt have the lightweight al balls and posts. The truck has the al hinge pin holders and hexes. If I used the eb 48 chassis on the truck, the truck would be lighter, but as they sit, the truck is heavier. Rx8 gen2 in both, t8 in buggy and hobbywing in sc, protek 130t and 150t al case in the truck and buggy respectively.

2910g. Sct410 rtr without battery

Depends on the dust/moisture level, etc. an aka impact in soft would probably be what I looked at first, and change from there.

man i'm at 3285 ready to go with .2 and I can still shed some more weight if i wanted by going to ti turnbuckles and removing the steel spur and adding some al screws in some spots.
