It don't look like the one I had for mine. I had the plastic with the twin slipper
pad setup. It was alot more capible of holding power.

Yep.. You didn't had one from the X-SS i think? (that's the kit version)

Nope I bought it seperate. But you know how that goes. :D

Does the X fit an SS tranny? I would think so...

I had to buy the plates and stuff to fit it. That was all I needed.

I have been in a holding pattern. Waiting for some parts. I should have them by next week. I will send pics and updates at that time.

John

Yeah, please share pics!

Well guys it has been a while...RC Rockcrawling comps (1st place in 2.2 class and 2nd in Supers) took most of my focus over the summer...well that and camping.

To get everyone up-to-date:

Currently running:
9L Feigao
Mamba Max
14 cells
14T Pinion
46T Spur
2 sp HD Tranny w/o reverse
Weighing in at 10 lbs w/o cells

Here was my first and only run...tranny blew up

Then the tranny blew...dropped in a 2sp HD.

Now with my question...

I am now jumping into LiPo...

What would be the best to go with...I am just getting into it.

Is the MM the right ESC and I know the 9L should be different...

I sold one of my crawlers so I want to buy the right stuff for this rig.

Give me your suggestions in this format:


ESC:
BL Motor:
LiPo Cells:

Comments:

Thanks for your patience and help on this..

John

I ordered a 5s LiPo for my savage...then realized that the MM will only handle 3s.

I see that Mike is changing vendors on escs. Would the Quark Monster Pro or the Barracuda be the best for my setup?

Please someone respond.

Thanks,
John

ESC:Quark 125b (will need the heat modification sooner or later after you start running it), or MGM 160/18.
Motor: 10lb truck, hmm,.... 9XL.
Lipo: Anything 5s? I would say maxamps, trakpower, trueRC- all the well known brands basically. Look for the voltage you want to run, a minimum of 4000mah, and 20-25c ideally. Obviously, the better the specs, the higher the price (true rc does 8000mah 10c packs that would be good; so long as the batteries can cope with the amp draw of the motor, you will be fine).

Whats your budget for motor and esc? there are much more efficient motors available than the feigaos, but with a lower kv rating like the 9xl it shouldnt be in danger of running too hot, especially with a fairly average weight truck- not a 13lb lump thankfully.

I can't spend a ton of money...this is going to be a backyard basher...would it make more sense to go with a 10xl with 5s to keep things cool?

Here is my problem...I have gone the wrong direction too much with this truck by purchasing the wrong esc and a 9L before I really got on this site. I now have a new 9L sitting...I want to do the right thing, only once.

I was looking at the quark monster pro esc in the store, is that what you are referring to or is there another Quark 125?

Soooooo Confused.

Thanks for helping.
John

With these numbers, do you think the 10xl would be the way to go???

I think the 10XL should be ok on 5s. Your going to use 5s aren't you? Because 21V is what you'd put in the calculator if you were using 6s. 5s comes off the charger at 21v, but when you put load on them the voltage will come down. 5s is 18.5v nominal, and for the calculator, use maybe 17-18v. Good batteries will hold their voltage better than lower quality batteries under load.

I don't know why it kept defaulting to 21V. I put in 5 cells at 3.7V each...It came up 18.5...I will try again to see...

Here it goes...

This is my recommendation to you:
ESC: MGM 16018 (I say this ESC over the 125b just because of the heat problem that it tends to have)
BL Motor: Feigao 9XL or 10XL; would you prefer more speed, heat, and less run time or less speed, less heat, and longer run time? (If you can swing it, go for a Neu 1515/2.5d; 1700KV)
LiPo Cells: TrueRC 5s2p 8000mAH pack will work great (There are better out there, but they also come at a price. Many people have had great luck with these TrueRC packs, including me :smile:)
