get at least 20c and above,I suggest NEU 1515 2.5 D with 3x2 s lipos , your motor might be too hot for your 14lb truck

Seems like a serious setup. It depends on who's batteries you get. Companies like truerc and SPC conservatively rate their batteries so 10C from them might be better than 20C for some other companies. Overall though, you may need some pretty high end batteries for this one. Whatever you do, you might want to gear way down at first and buy one of those in series watt meters so you can see how much power you are pulling. 6S and 14 lb truck though could get you into some serious trouble if its not done correctly.

what do you mean it could get me into serious trouble and how can i see what power im pulling
im not electrically minded

what motor would you recomend does it need to be a lower kv rating for a heavier truck

im looking at the true rc 11.1 5000mah 15c lipo
3s1p5000-15c

or the zippy-r lipos of about the same rating

That is a high amp motor better suited for 3-4s. You need to look at the 1515 1y at most and better would be the 1515 2.5d. I would place bets that with that motor on 6s in a 14 lb truck that you will see fireworks and not the good kind.

I run a 1515 1.5d in my erevo on 4s lipo. It runs well on 4s, but would not suggest running it on 6s. The 1y or 2.5d would be better suited to 6s in that heavy truck.

I have an aftershock converted to BL. I run a hacker c50 11xl (1500kv) on 6s lipo with a MMM. I am curently using a air of polyquest 4500 30c 3s lipos in series. Those batts are rated quite high, but will still get warm with this setup. I would say that a set of 5000mah 25c 3s lipos would be the minimum, and if I were to buy lipos again I would buy the polyquest 6000 25c 3s lipos. Unless you go with a large capacity pack, like a true rc 6s 8000 15c pack, the 15c-20c packs will not keep up.

If you want to run the 1.5d stick to 4s, and you will need very good lipos. The polyquest 6000 25c lipos would be the best bet for a 4s pack. I would sell the motor and get the 2.5d and go 6s, that will yeild the best results with that heavy truck.

well i do have a gorilla max revo conersion that i run a mamba max on 4s with a f/7xl i suppose i could put the 1515/1.5d motor in that truck i may need to get a mamba monster for that though

i will look into geting the 1y or the 2.5d ill see if mike has any in stock
cheers for the advice buddy............................................. ....................

The MM should be ok with the 1.5d. Just run an external ubec and a fan on the esc. Maybe add another capacitor. It will pull about the same amps as the 7xl. Plus the neu will be more effecient, and use lower gearing than the 7xl for the same speed, the neu has a higher kv, 2700 vs 2300 on the 7xl. It may even pull less than the 7xl, maybe?!!?

that sounds good dont really want to spend more on another esc

what type of cap would i need to use on the m/max i dont no nothing about these but i no you put them on the main power wires
i wouldnt no where i could find one either im over in the uk

i do use a ubec on the max all ready got this from mike
do the small 25mm fans really help keep it cooler or shoul i go bigger like a 40 mm fan

@Lincpimp, what speed do you get with the Aftershock on 6s?

With the stock tires, 24/59 gearing, and the FOC with the gears swapped, it does about 42mph. I was suprised how controllable it was, the tires did not balloon too much.

You can buy a wattmeter for around 50 bucks from towerhobbies if you are curious to see how much power you are pulling. You just put it between the battery and esc and you can get amps, volts and power. I think these guys answered your question. That motor is more of a 4S motor than 6S. Sorry I didnt answer quicker, I lost this thread.
