Losi XXL brushless conversion

[Big House]

The rig....Losi XXL roller in excellent condition.

The vision....Huge truck moving ridiculously fast on grass

The plan....Break down, clean up and shoehorn a 1717 in it.

Here are a few shots of the break down.

[Overdriven]

You going the easy way (with a trans) or the hard way with a center diff? If the motor sitting there is any indication, its the hard way. Its actually not that hard, especially if you have the motor over the spur gear instead of next to it like a typical 1/8 buggy layout. Things get cramped quick with the motor next to the spur gear, especially with a big 1717 in there. Just curous, but is that the XXL chassis or have you not installed it yet? Asking becasue I notice 4 screws from chassis to side rails (LST, LST2, aftershock length) and the XXL has 6

I am definitely going the hard way with the motor mounted on top. And from what I have seen it is the XXL. I removed the transmission motor and servos before taking this picture so I might have removed something I should not have. I plan on using the center spool unit like the one in my converted GTP2. The electric version came out after I finished my build. It is tried and true and should make things a little easier for me. The hard part will be the motor mount, still drawing that one up.

I've heard the Ofna LX series (GTP included) CD and spools fit with the stock center shafts, making things easier. Mounting the motor above the CD makes it easier as well. I have a RC-M Losi mount and CD that I'm stubbornly trying to stuff into mine as I want the motor low. Can't wait to see more, love the LST stuff.

Not trying to be one of those internet know it alls or a buzz kill, but I double checked the chassis situation. The pic below is a XXL, and the red arrows point to the screws I mentioned. XXL has 6, LST/aftershock have 4. Its really hard to tell where they stretched the chassis on these except for those screws. I just know I'd be really pissed if I found this out the hard way, like after ordering parts like center shafts for an XXL.

Second that. Also the LST2 came stock with the anodized, threaded shocks like that. The XXL has an all plastic threaded shock.

That is one bigass shock!

Sadly I found them weak - I kept snapping the shaft at the rod end.

Arct1k,

I appreciate the info. Upon further investigation and using your pics, it is an LSTII. I guess I can refine the parts search. The only thing with the center spool out of the GTP, the cups are a bit short so I will need a longer rear CVD. I have a Mayhem ST with a beefy rear center shaft. If can find that I will be golden.

I used a dm-1/gtp spool in my E-LST. (I believe they use the same spool?) Anyway, the shafts barely sit in the cups but it does work. They are actually sitting in the cups farther than the shafts sat in the lst transmission. Pic:

P,

What motor are you using to push your truck? The amount of metal on this thing really concerns me. It is going to be well powered but the lighter the better.

[Big House]

But will be even more rewarding...I cannot find the Carbon parts I want so they will have to be hand cut. the flat pieces. The front plate will be replaced. I love these type of builds. Firsts new parts should arrive tomorrow. I will mock up the center diff assembly and motor mount. It will be a carbon fiber aluminum angle two piece.

Mikes universal cd mount shoud work great on this build

tekno neu 1515 2.5d, 1650kv. My truck is full aluminum and it tosses it around with no problems. The 1717 you plan on using is plenty of motor.

[Big House]

That is the idea. I am going for the extra wide wheels so thew extra motor will definitively help there. I hope the CF diet will get it down to 10 lbs with the motor and lipos.

[Big House]

The Ofna parts worked without a hitch. The diff is mocked up and if fully functional with the existing aluminum pieces. Once the CF plate comes in, It will be cut to match. Here are a few pics of the center diff in place.
