One would gear down when using higher voltage, otherwise you will be spinning the wheels to fast to control the truck.

I think your genral issue is that the motor you have is too fast for 4s & racing (4s & bashing would be fun though), yet on 3s it will be pulling quite a few amps if not geared conservatively; most people tend to run the 1515 1y on 4s, or the next slowest motor option on 4s/5s.

I would stick with 3s if its working good for you, just gear as required to get your desired speed and 'oomph' levels vs temps.

hmm...i guess it's a 3S for this motor and the race, then.

ah...well, I guess it's best that I stick to the 3S packs. Guess I'll get me a couple of the TP 40c packs.

sheesh, that's alot of $$$. :oh:

hokay...I'm stuck between these choices. Any recommendations? I'm looking for good power, reliability and best cycle life.

any suggestions?

Honestly you'd be better off selling the motor - You'll always be fighting with that high of a KV...

or wait a minute...


maybe I can try all three!!!! :oh::intello::yes:


any feedback on these batts, though?

:surprised: :oh:


come now, man...surely what you say is sacrilege?!

sell...my...motor? yikes!

hokay...so say I was to sell my beloved 1.5D, what motor would I need to pick up? I'm looking for something similar in terms of speed and power.

any suggestions?

and FWIW, I absolutely love the speed and the power that this motor gives me. :)

that, and I only have one 4S in my battery flock. The rest are 2S and 3S.

Tis' another reason why I'm partial to the motor: it works well with the current battery inventory that I have.

sames series - trade down the KV to something in the 4s range 1800-2200kv

ok. :yes:

how is the motor comparison, though? How would a 1800kv on 4S compare to a 2700kv on 3S? a 2700 on 4S?

If you match the motor kv to the voltage, and aim for the 30-40,000rpm range, then 'power' will be pretty much even once you take into account gearing for the same speeds.

Anyways, the PolyQuest 3s lipo is pretty beasty, but I would look into the new Hyperion Gen3 packs (Mike only has 5s packs at present), should be able to find them for sale somewhere- Mike wont mind as he doesnt sell them :lol:

ah hmm....I see. I think.

I think I may give it a shot, then. Need to find the $$$ for the motor first, though.

what about the PolyQuest vs. C-Tech RC packs? I've been hearing about the G3 packs, but I'm trying not to break the bank in my purchases. At least not yet...

I'm liking the C-Tech for it's budget, but I'm also liking the PQ for it's capacity.

Anyone have feedback on the power delivery comparison for the two packs?

I only have good things to say about my C-Tech 25c packs. I run them in my truggy and they have awesome power.
I'm not sure if you wanna go with 4s battery or whatever but a lower KV motor can really open up your battery options.
