Is this lipo combo sufficient?
 

Hey guys, i have a Hyperion 4200mah 35c 3s lipo sitting here brand new. I was thinking of going and getting a 2s 4200mah 35c pack to run along with it to have 5s in my flux. I know the minimum the Castle ESC likes is 125 amps, and that this combo provides 147 amps. The only reason i worry is that ususally its recommended to run 5000mah and 30c at least to be sure you have enough juice to run the truck. Basically im looking for a little reassurance before i go and purchase something.:neutral: thanks in advance fellas.

Gearing is a big part of this also, if your gearing is conservative I see no issues. Moniter heat the first few minutes, that will dictate everything.

Seems like an OK combo to me. Those 35c packs will handle the high burst current just fine. The only reason I see for you to go to 5000 mah packs would be for speed runs.

Thanks for the advice guys. would you consider 20/44 (stock) gearing conservative?
as for speed runs i do open it up but never hold it there. its always off and on, but im not afraid to top it out with my 4s lipos right now.

You should be ok but alot of peeps here would say go down to a 18t or lower pinion for safety.

+1..

That will be fine. I'm running a mere 5A 20C = 100A for over half a year or something and they perform just like my 30C versions. You can probably drive with 20/44, but 18/44 would be safer. I would also advise to start with 18/44 and if you feel the car it to slow (or just want to experiment) do with 20T and keep a track of your temps.

ok thanks for the advise guys. i have extra pinions already so ill give it a go.

just placed my order. rcmonster never had it but rc lipos did and i also found a discount code that saves 10% Only $63 shipped all the way to Canada! my lucky day i guess. time to go pull the flux apart now and change that pinion.
Are Novak pinions any good or should i be ordering a new one right now to save the hassle?

Personally I think the RCM pinions are the best, Robinson and Novaks are a tie for second.

ok well if i have any troubles ill invest in the RCM pinion. Thanks for the heads up!

I can't believe how farking fast i've already worn out my stock HPI pinion on my Flux, I may need to replace it sooner then I thought

ya i just toasted mine on the last run. im thinking when the old man hit post it knocked the motor loose.
( i know, never let anyone drive your rc's but its my pops. lol.)

buying this lipo is the kick in the ass i needed to get motivated to clean the flux up and fix her up a bit. i might even do a little thread about it. Stay tuned folks.

well guys i just wanna thank you for the guidance. the lipo came in about a week ago, and tonight i finally got some motivation to solder. i charged them up as a 5s pack and let it fly. took it easy at first, and it seemed good, temps were at 70 F on the motor and packs, esc fan was off. The highest the motor got too was almost 100F and the packs were only warm, no where near hot. ESC fan kicked on near the end but only after speed runs. it was a cool night tonight so ill continue to monitor temps, but still a big thanks guys! the truck is great on 5s.

Nice1 88!!! glad you running smoothly!!! Those hyperion lipos are awesome for punch! but just make sure they are well protected as they fail pretty easily because of bad soldering connections.... just a heads up...

My Novak pinion has lasted the longest so far. with around 15 runs... hpi last around 3 runs, RCM lasted around 9 runs, answer pinion lasted 30 seconds (my fault maybe, bad mesh)
But i rate novak at the moment...

Good to hear 88. Not surprised though. 140+ continuous amps is more than enough.

ya i was just worried since what i read is all i honestly know. HPI says 5000mah plus. And Jahay i use alot of padding in the boxes to keep them situated. thanks for the head sup tho. hopefully the novak lasts, ill let you know.

i use a robinson racing pinion and it wont die. cant count the hours of use i got on it so far
nice battery setup

gdot... what do you run??? our savages seem to go through more pinions because we have fat asses...

i may try robinson at some point, but im very please with my novak ones...

would people be interested in TI pinions if they were available? and how much would you spend on one?

i have a db17 with 5s and ofna truggy wide offset rims/tires i got from ebay. 5s is my fav combination for it. the stock pinion lasted 5 runs, the robinson one well over a year

I'd pay $50 for a carbide pinion.... :mdr:

GDOT!!! we run the same chassis... so we both know what sort or stress the pinion goes through!!!
THATS AWESOME NEWS!!1 i will check out a robinson pinion if you have had that much success!!!
5s??? why???? the db-17 is perfect on 6s!!! what gearing do you run by the way?
oh and where do you get your robinson pinions because i cant find them?

Sorry bud... dont think he dabbles with carbide haha but titanium is a possibility...

they have dealers everywhere i can think of. heres their pinion chart

the 6s seemed to crazy for me but if i try the cd like you did then it might be nice. the 5s is perfect for my driving and where i bash it. crasy speed and long running with 20t on a 44t spur still. its stock flux parts but used the hd trans gear inside not the speed one

thanks for the link bud!
How are you finding your temps with the stock gearing and motor on the db-17?

Thanks for the link too!!!

hah sorry to notch for using his thread
the motor goes to 130 sometimes, the rest is under 90 mostly so no problems ever. just rips everywhere

yea sorry to thread jack...
Thanks gdot... those are decent temps! i guess the truck is lighter now considering you have lost the weight of the Lipo boxes...

thread jacking is fine by me, savage info is all im after. lol. glad to here about a new pinion option too if i have issues. and also id be interested in a ti pinion if it passed testing. Id pay 30 max, and thats if its got some good feedback.

thanks for the feedback on the pinions... ill mention it.
