Sike00 thanks for sharing your experience
actually there are different HPI Savage RC's,
this setup is in the Savage xs as stated in the post, (not in the much much bigger Savage 1/8 that you refer to)
the xs is a heavy machine, rather strange because it's 1/12 or so in size but handles like
a 1/8, motor space is restricted to 56 millimeters lengthwise hence the use of the HW 3656 motor
but I'm having a lot of trouble with the 4700kv hooked up with the SC8 esc,
so I'd be interested to know how it works out in your SCT, as it seems the 4700kv has a pretty hefty amp draw. So what batt are you using, what gearing and what kind of run times are you getting,
anyway a BIG thanks to the HW techs for this amazing thread...

I havent got the kit in yet, should be here this week, its in the mail, the pinion is a 12, as for batts i havent purchased any yet, still trying to figure that all out, so the C rating estimates the amp discharge rate, so on the motor/esc combo is there somewhere it states what the amp draw can be, i assume it would just be an estimate as gearing/weight of vehicle all makes a difference. The truck i am getting is pretty light for a SCT so hopefully wont pull huge amps, I dont want to have to get 100C batts just to run truck, i havent even got a charger yet as not sure about that yet either. Is there a chart somwhere or a formula for figuring out how fast say a 6000mah 2s batt charges at different amps. Also some batts are listed as 2s, some 2s2p, some 2s1p,,,is there a difference that makes a huge reason why to get one type vs the other,mand whays a good budget/starting batt brand. I dont want to melt a batt because of load thisncombo pulls.
Also with that combo in a 1/12 that thing should be just anout slightly controlled chaos wouldntnit,,hahha
Also i understand the whole term of series and parallel ont he batts, justnwondering if one type is better

Yay
got a SOLUTION that works for me
here it is
I disabled the lipo cut off (setting 3.1 on my HW program card)
then rigged up a lipo alarm (those little 5buck jobbies) to the balance plug, set to 3.2v cut off
had time to run about 1/4 of a pack thro' and the car was fantastic, power was so clean and smooth, (esc and motor were only warm)
took the batt off and tested and still had way left, will do some more testing but I used to use this alarm with lipos in my old Tamiyas and never had a problem
so it seems to me that the esc is overly sensitive to voltage spikes
- time will tell how well the batts hold up, but at least for now I keep the amazing speed, smooth power delivery and save myself another motor....

I just bought the extreme stock. Question 1 do you need a computer to program the esc or can you do it with the programming box by itself? Question 2 whats the reason that the esc has 2 different moror limits with 2cell for onroad and offroad? Thanks

Which esc would be suitable for the TD dex410v3 4wd buggy with a 8.5t brushless sensored motor? I'm not sure what servo yet. I also have a spektrum dx4s radio don't know if you need that info or not.

Anyone have any experience with the RMA process? My esc is not working and out of warranty. I got my RMA number and am getting ready to send it in. What I am looking for is 1. how long do they typically take to get back to you with a solution once they receive it. 2. Since I have to pay for the repair, will it be some crazy amount? The esc is $89 so a repair costs shouldn't be more than that? 3. If they can't fix it, is it then junk or do they have a trade in program? Thank you.

I had to send one back for warranty service and could not be happier with how they handled the transaction. Top notch customer service with great communication and fast turnaround. HobbyWing has a customer for life!

Thanks. I haven't had to send an esc back ever. let alone a company that is not in the states technically. So this is good. I just didn't know if it is even worth trying to fix. Sometimes it's cheaper to buy another one.

hey guys. just finished up my dex210 2wd buggy.
im using a v2 speedo. The thing is that its a very tight fit with the fan on. it touches the body. Can i use the v2 without the fan?
im using a turnigy trackstar motor 8.5 t.
and what firmware do you recommend? i just flashed the esc to the 930-stock firmware. Is this one a good starting point for 2wd buggy?
thanks
