HW1080+Promodeler 470... BEC necessary???

FWIW I poopooed on people who were super recommending a savox 2290 because of its excessive torque and I thought it was overkill. I now have a HH 500v2, and I love it compared to the servo it replaced, but it still doesnt move the tires in situations I feel it should be able to. I run the CCWP2.0 bec as well. I feel like running your 470 at a lower bec rate would not make you very happy with its performance, but it really depends on how you feel.
 
Just read a bit more posts, and on HH vs PM I went with the HH cause they were in stock and the PMs werent. I dont regret the purchase at all, but this can be an issue with any smaller companies that end up having a very large demand.
 
In my TF2 with the stock RTR Twister servo and with DS3218 $20 servo hotness. I stalled both servos (was not trying very hard either), the DS3218 was way more powerful and didn't get hot like the RC4WD Twister did, unfortunately neither is rated for 7.4v.

That is very, very odd. I wonder if the Twister or the other servo is defective and drawing more power than it should?

I have a 1080 in my TF2 and after a few backyard tests and one trail outing I haven't had an issue.

Can you explain what sort of situations you ran into where a 500oz-in servo can't move your tires? I'm clearly not working my trucks hard enough, because I still haven't bound up the 300oz in servo (running on the stock ESC) in my Gen7, nor have I ever encountered any situation with the 470 in my Bomber where I was short on servo power.

I wonder if leaving my HW 1080's internal BEC set at the 6.0v setting is what has allowed my DS3218 servo to keep on truckin' for so long without issue?

I've debated on whether to push it to the 7.4v setting, but haven't yet because it's doing so well at the moment... and given that I'm coming up on 8 months trouble-free, I think I'll play it safe!

I'm only running 80 oz-in on 5v in my CA-10 and I don't have any issues where the tires won't move when I need them to. My Mad Crusher GP, a 1/8 nitro behemoth on six inch tall tires, only has ~150oz-in and it steers just fine. My SC10GT's only rocking about 70OZ-in and I can point it wherever I want to on command, and I've got it on a set of ProLine 1.9 BFG ATA crawler tires instead of normal shortcourse tires!

I'm also curious what his answer is, 'cause I just can't see a situation where anything this side of a Baja 5B would need that much torque for steering.

As for BECs...I'm of the mind that it's one less part to go wrong/drain your battery, so if you're not having brownout issues running off the ESC's built in BEC there's no need for an external one. Run one if you need it, but if you don't, that's one less component to worry about/fail.

Here’s a reason 500 oz won’t work.
11# of Wraith on 3srunning tall , big tires in rip rap. I ate 3 Holmes servos(V1&V2) ripping the gears out. I bound up a PM470. The 2290 centers every time , and will allow this pig to turn.

Not odd in my experience with crawlers. Doubt I've got two defective servos in a row (it is of course possible, but unlikely) and esc works fine. We've got lots of rocks here. I used to run 2s and 3s, been exclusively 3s for awhile now. BEC is cheap insurance and combined with HH rx bypass harness, has alsways worked great. "thumbsup"

Probably, every time I've gone over mfr's recommended voltage by more than 0.2v, I've burnt up ESCs regardless of brand. Do it and let us know lol j/k. :lmao:"thumbsup"

I run a hh500 V2 DirectX from my 3s lipo in my T-Rex and i'm very Happy with it.
No external Bec needed.....
and on 3s it's a beast in a stall it moves my 11lbs T-Rex in stead of the tires.....

Ok Im going to try to articulate this but Im not sure how well I will do so bare with me. So basically lets say im in a situation where there are two rocks creating a sort of chasm between them. One is higher than the other. So I get a tire up on the lower rock, and try to ride the wall up over the tall one. I will turn right to keep the tire steady on the short rock on the right, and then when I try to turn back straight or even a little left I often get stuck full right. The servo is working it just cant straighten out. Does that make sense?

do you mean the SHV? there are two different hh500s, one that is 8.4v and one that is 12v.
 
My Bomber on 6" tall Losi Maxxis Creepy Crawlers locked up a ProModeler, but even the best occasionally have issues - I hadn't driven fast through big rocks or gotten it in a bind, so I think it was an aberration... They've already said they'll fix me up, no worries.

Swapped in a never-powered up v1 of the HH SHV500 (that I bought 2 YEARS ago, that's what I get for taking so long with my build) and had it go wonky on me a few days later, same situation - but thankfully I got it working again (not sure what happened there?) - and just before I fixed it Holmes Hobbies replied to my question about returns (that late after initial purchase!) in a similar positive manner.

That's why going with a company like these is the way to go - incredible customer service, and support for our hobby.

I know but i have the hh500 running on 3s. Jrh wrote in a thread it can take 3s and so far mine works great.

Looks right to me.
I’ve owned both the Holmes and the Pro Modeler (420 &470) the PM is far better IMHO. I ate 3 Holmes , JRH warranted them (1v1 and 2v2) ate the gears, look at the difference. Both John’s are first class people selling first class products with fantastic CS from both.

So which way to go ? I just built a VS4 10, you can see my PM 420’s scratched bottom in it !!

Side note. Im setting up my new VS4 10 (scx 10 almost) and chose my trusty PM 420. went right in, and I discovered I had to DROP my voltage down to 6.5, as the 420 was too fast ! that was a pleasant surprise, more servo than needed!
 
I dont think it was mentioned, but the BEC also will stop any potential glitching of the receiver and flickering of LED's that you may have hooked up when the servo is moving.

The ProModeler was supposed to be back in stock late July, unsure if he ever got more in. I went with a Savox 1230. 500oz at 6v and .15sec. Not the fastest, but works great on my 7lb rig with 1.9''s. Costs $70.

Ive got a nearly new Castle 2.0 waterproof BEC for sale if needed. Came off another rig i gave up on building.
