My RC8T CE brushless build (tekno V4) - RC-Monster Forums

Ola · **My RC8T CE brushless build (tekno V4) -** 04.18.2011, 05:45 PM

Just wanted to share some pics

RC8T FT champion edition
Tekno V4 brushless conversion chassie kit
Castle 1520 1600kv
MMM esc
Hitech 7955tg servo
GPM alu rear hubs

It`s built exactly after the factory specs like the winner car`s setup for now, only with some thicker diff oils..
It will be used as a basher only for now, as i dont have tracks anywhere close...

Almost done.. Tires are glued and drying up now, and exept some minor wheel stand adjustments, the body painting is the only thing left to do..
Waiting for my new 5s batteries to arrive though.. Should be here soon.

I love the quality of the AE kit.. :)

Sorry for the semi-crappy photo quality.. It`s taken with my cell phone..

Ola · 04.19.2011, 10:42 AM

Well, the battery`s showed up today, so i got busy ;)
It`s all done now.. Sort of ok happy on the paint, absolutely happy with the install, and VERY happy about the car`s handling..

Nice...interesting how the new kit puts the center diff so far towards the rear.

Ola · 03:48 AM

Yeah, i dont know why they do that, but i THINK i`ve read that it`s to get other parts closer to the center of the chassie..

Theres one thing i dont like about it though.. The diff sits kinda high, so the angle on the rear center axle is bad. Maybe it works great for all i know, but i smell wear when i see things like this..
I changed my spur to a plastic 50t esterday when i went up to 120k wt in the center, but i still couldnt remove the base plate under the diff (its a 3mm plate between diff and chassie, so the spur shouldnt stick underneeth the truck)
I think i will change to a 46t steel spur from the rc8te soon, so i can remove that plate..
The angle looked alot better without it!

Geared up to 48mph yesterday, and MAN did the 1520 wake up! Together with the 120k wt oil, the truck got real fun to drive..

truggys is often based uppon the buggy couterpart so the gear ratio is the same, thats why the center diff use shims to make room for an bigger spur. in theory if you use some lubrication you should not see any extra wear

48mph is almost 80kmt thats pretty fast for an basher, im geared way lower than that on the exact same motor so watch your motor\esc temps, especially if you plan using 46t

Like your build it lokks real tidy

Very nice Ola! I like truggys, I like the look. How much does it weight? No dead diffs yet? ;).

That thing must be hauling A** @ 48mph! How does it behave in the air? Easy to backflip? Those tires are "belted" right? so they don´t balloon so much? Like those I had on the revo and now up front on the flux.

When you are out bashing, do you have a ramp at home or do you have a sand/gravel-pit to drive in? :). Feed us with some Action shots!

Ola · 04.21.2011, 01:52 PM

Alot of people claim these diffs to be VERY strong, and it seems to be true.. :)

It is exellent to control in air, but backflips aint easy with these tires.. With MT tires it should be easy though! They dont baloon much since i`ve taped them, but i dont think they are belted.

No ramps here.. I usually bash in some huge bravel pits.. But i run alot of the time all alone, so no one to film/take pics.. I`ve tried to bring my 6y old daughter to film, but she cant keep up LOL

Here's, for comparison purposes, Mike's conversion chassis. I can definetly see what you are talking about with angle of the rear axle. In comparison Mike's uses standard RC8T axles, no custom ones unlike it appears the Tekno conversion.

Btw, I would definetly suggest, as you are, the plastic chassis braces. I went through several of the aluminum rod braces, bent them up pretty good, and one set of the more expensive aluminum braces. I've switched to using the plastic braces as they give some more support but also flex a bit and are cheaper to replace.

Yup, but when i go 46t and lower the center diff, then the RCM kit angles are actually way worse than mine..
And the RCM kit wasnt available anyway, so it wasnt even an option when i ordered..

The braces are Tekno`s, made only for V4 kit`s :) But i`ve read other places, that youre absolutely correct on the plastic braces vs alu..!

I've been running the following on mine:

5S with Badlands (1800kV)
spur: 50t
pinion: 16t

6S with Badlands (1800kV)
spur: 50t
pinion: 15t

6S with Baja Trenchers (1800kV)
spur: 50t
pinion: 13t

Thats about where i`m at now (approx 48mph@3.7v) :) But i run 1600kv on 5s, 50t/20t...

Not been over 130f/55c yet, even with outerwear cover on.. I think i`m in love with the cc1520..

brainanator · 04.21.2011, 04:15 PM

Looks really good! Thanks for posting :D

thzero · 04.21.2011, 04:18 PM

Yeah I have a 1520 too... thinking about swapping the 1518 to the 1520 myself, especially since I'm doing 6S these days.

I was going to ask, but temps, etc. seem good with the outerwear? Is that an RC8T specific one?

I`m very happy on the temps.. I run hard, and still keep 130f on both motor/esc.. my 30C 5000mah turnigy`s was showing 85f after 22min`s today, on it`s second cycle...
Dont forget, with cover on.. Alot less cooling wind..
And these temps was with badlands, not the stock (lighter) tires..

The outerwear is made for the E-revo.. i got 2 covers, one original outerwear, and one cheap version i found on ebay for 11 bucks or so.. The ebay one is slightly longer, and fits the RC8T better so thats what i use now.. Both types are fit with velcro, outside the mud guards.

It doesnt seal up the rear as good as on the E-revo though.. But i put some velcro on the chassie under the rear center axle, to stick the cover onto.. Works great..
I do get alittle sand into the chassie, but nothing compared to without the cover.
I also have 1 layer of outerwear on top of the MMM fan, to keep it clean. (a cut out from an old cover)

The V4 isnt as wide as the stock chassie though.. But i think the cover fits anyway..
