Latest conversion project - HB GT10

[VintageMA]

I know it's not a new model, but been wanting to build one of these for a while. Definitely paid more than I had hoped having to order it from the UK, but after about 2 weeks wait it just came in the mail last night.

Here's my thoughts on the build:

HB GT10
TP eXtreme V2 2600 - 6S lipo
CC MMM ESC
RCM motor mount
Custom battery tray from Mike 40x132mm (just ordering this now)
Servo - not sure yet, will try stock one to start
Neu 1512 3.5D (1500kv) or 1509 2y (1820kv) (have both, just not sure which will be better)

The motor mount side of the car looks to be a pretty easy setup, but the battery mount side may be a bit tight. The spur is pretty huge at 54T.

With stock gearing of 12T/54T pinion/spur and final drive of 13/40 the speed calculate out at just a touch over 35mph with the 1512 on 6S and the 1509 on 5S. I would save about 1/4lb with the 1509 on 5S compared to the 1512 so that may not make a big difference either way.

Going to fleabay out the nitro and radio stuff to make a little back.

Some pics to follow later tonight.

If anyone has some input on shock oil weight and diff oils to try front and back I am open to suggestions. Also if anyone knows any mandatory or recommended upgrades to help reliability please let me know. From the threads I have read, the front and rear CVDs may be a necessity.

I have read the stock tires are just OK, but at an odd size of about 5" I'm not sure what alternatives may be out there. Since I'll be running it on most grass and off-road gravelly stuff the tires may be fine.

[rootar]

the gt10 is an ls10 with dual shocks, taller shock towers, different body, and 14mm wheel hex with maxx size wheels, right? is there any more chassis changes?

go with 35 wt oil in the rears, and 40 in the fronts to start with since you have 4 shocks on each end

[VintageMA]

Yep - that's pretty much it I think. I checked that parts list before making the purchase and it seems almost all of the LS10 and GT10 parts are the same model #s.

I'll probably run the shocks stock just to check out the handling and adjust form there. Will def fill the f/r diffs before running though.

Thx.

For a similar height tire, the panther kmodo gragon lp tires on maxx rims should do. Part number t140ms on the tires, not sure what offset wheel to use...

Sounds like a great conversion, the 1512 on 6s will be a beast. The 1509 on 5s may be more driveable.

[rootar]

youll use half offset wheel with the komodo LP's i run these on my LS10 and my slash, if your wanted a tad bit extra width go with the rpm stable maxx wheels they are nice.

front diff use 7000 and rear diff use 3000 or less if your just bashing itll be a blast with out a center diff but if you want it to handle and run like an 1/8 scale use a crt.5 center diff with 5000 in the center and itll handle completely different and my rear dogbones are lasting ALOT long than they did with the slipper.

+1 on the 1512. Sounds like a great conversion!!

The icky nitro stuff - I think the STOP label on the motor should read "Remove before using vehicle".

I have a set of these if your are interested. Used slightly on my old GT10. Much better tires than the stockers. PM me if you are interested. Cheap. No use for them any more myself.

[Gee]

That will be a nice setup. I'm enjoying the ls10 I got. The Neu will be nice in it. I've been messing around with the cheaper motors and trying differnt KV and pinion. Always seems to come down to the motors temp. That shouldn't be a factor with the neu.

Are the carries for the GT10 and LS10 the same? I seemed to go through a lot of the small bearings so I'm trying out f/r carries that take the larger 5x11 bearing now. Seem to be holding up a lot better as far as the bearings are concerned.

[VintageMA]

This weekend I got the motor mounted, filled the f/r diffs (7k/3k), trimmed the servo tray down and got everything ready for a quick trial.

The brand new MMM went up in smoke when running the wheels slowly holding the truck after about 30 seconds after calibrating. It was working okay and then just a pop burnt smell and then nothing. It took one of the HPI SF-1 servos out with it too (glad it was a cheapo servo and not the good one I have on order).

So to a back-up MM with 5S and CC-BEC, still using the 1512 and 12T gearing. Just been doing a little small driving around the house to check things out. The MM was getting a little warm on 5S so I need to pull a little fan out of the toolbox to cool things down.

Right off the bat I can see a few pretty weak areas. The hub carriers seem to be a little thin and the a-arms seem to be very soft and bendable - not sure if that will be a problem.

The servo saver is pretty flimsy, but I found a stornger plastic spring, so we'll see. The stock servos are pretty slow and not too powerful.

Still waiting for the battery tray - so cell just ziplocked in place to test out the truck. A few pics to follow.

the arms are TOUGH i have broken one of the front hub carriers, youll need to get better wheel and diff bearings, get the half rubber sealed/ have metal sheiled and put the sheilded inside towards each other and that take care of that problem, you can also ditch the stock servo saver for a heavy duty kimbro one for and old style emaxx/tmaxx.

oh and when you really get to run it the body mounts are as good as gone you can get some losi eight-T body mounts and snip the bottom holes off, you can also use rustler/pede/slash rear body mounts front and rear with minor trimming.

[rootar]

MY BAD the body mounts i listed will not work on yours due to the extra shocks, hmmmm whats gonna happen is the post is gonna break right down at the bottom, you could cut and sand them off and drill a 3mm hole through where the post goes and use some of the removable front traxxas electrics post (slash or rustler) and cut them to the length you want.
