6s is less strain.. lower amp draw = happier ESC w/ lower temps. Batteries also last longer (cycles) and typically can run a lighter pack or longer run time depending on the choices you make.

It will handle 6s but you may need an external BEC. The Built in BEC is a bit weak in those. 6s with a low KV motor (1500kv or so) is very efficient and will be easier on your esc than a low voltage / high amperage setup.

Edit: HW 150a bec is very strong.. never had any issues running multiple good servo's (stay away from savox)

YES, and as noted it's not legal for real ROAR events (yet). I'm sure at some point roar will get their head out of their rear and catch up with every other event rules.. everyone allows 6s at this point for large 1/8 tracks.

BTW with the gear ratio of the tekno etruggy you want lower KV motors, 1350 is your best bet w/ a 6s config. 1900kv-2000kv w/ the 4s config. You cannot gear a 1550kv low enough w/o some mods to allow a smaller pinion. (may not be able to run the center brace at all)

Also worth noting if you stay away from Savox servo's and you won't typically have BEC issue in any setup. Savox are literally the most inefficient servo's you can buy.. why do you think they are so cheap. Will they work.. sure will they ever be in any of my vehicles? Not unless they start paying me to race um LOL.

JeremyMcG look this page and see my post on the new shims with the picture of my rear diff. I emailed them on a Monday and I had my new shims on Thursday. After five packs through with the new shims I had no wear. Tekno takes care of their customers.:batman::spidey:

Just can't ask for better service. Tekno is top notch.

Will handle it fine. No issues.

Thanks for the responses guys appreciate it. Going for 1550kv 6s setup - placing the order shortly.

You are going to love the 1550 kv really happy with mine , good luck on your set up .

Me too, it's awesome. Killed a fly with the wing yesterday.:lol:

True story.
On another topic, when i exit slow corners my truck tends too spin out easely.

What would you change first?

Setup is stock, exept 10 x 1,2 pistons, 500f 400r links are one position lower on towers.

thicker rear diff and lighter center diff by little bit from where your at.

mamdot91 02-26-2014 11:15 PM

What diff oil options do we get in this kit? And are the amounts substantial or hardly anything?

JeremyMcG 02-27-2014 05:44 AM

You get 20k and 10k in the box. Tekno gives you more than enough to build your diffs.

As noted you guys are crazy w/ such a high Kv motor on 6s lipo you can't gear it low enough... at least for racing. With the center brace in you are limited to a 15t pinion.. that is almost too much for the 1350kv t8 motor let alone the 1550. Maybe you are bashing though and it will be fine.

UK.hardcore 02-27-2014 06:13 AM

I shaved the brace and use a 14T.

Yes if you shave the center brace you can run a 14T. The brace is thick enough that it does not effect the integrity of the brace.:batman::spidey:

I mostly run 5s and a 15 tooth , and i run 6s on the 15 tooth just to crazy no over heating issues at all .
