R/C Tech Forums - SC10 4x4 Thread

Whelp, This will probably be the last time I post as a AE owner. I'll still be around to answer questions and piss you guys off though. ;)

Long story that I don't want to get too far into as I don't like to bash companies and I know i'll get ripped for it, but I'm done with AE. They have stretched my patience and customer loyalty too far and will lose a driver for it. (if for some reason you'd like more information, you're free to PM me) So I'll letcha guys know when I get my truck's thread all up and done to sell. It'll be a good Truck to anyone, I worked hard with it. It's The RCtech page 1 Sc10 4x4 like you veterans.

I haven't decided to go to Losi yet, as I really don't like them even if i'm no longer their competition but we'll see. Thanks for all the help guys. Sorry for my attitude in the past and I hope to continue helping the guys who won't use the search function. ;)

Bummer. I just got a desc410r. Good Luck

Has anyone got any tips to stop the shock collars moving?
Mine are very loose and I'm sure they move.
I've put some thread lock on the threads and let it dry but the collars are so loose it doesn't provide much friction.
I'd rather not buy the STRC ones if there is a simple fix.

Glad you lime the servo, ilanstylz! If that had been the torque version it still be in my truck right now. Very high quality and the specs don't hurt either.

Will a "Novak Ballistic 550 Brushless "Short Course" Motor (4.5T/5000Kv)" drop into a sc10 4x4? Or does the chassis need to be modified?

I think it will drop in. Most 550 Motors fit (i dont know one, that doesnt fit). How long is it? But as i wrote a few pages befor, the chassis may damage it a bit (just optical, scratches and so on).

@Vegatron: why? the truck would have more traction-roll and a higher mass-center, wouldnt it?

Good bye Coyote :cry:
Officially done with 9th grade. Summer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Sorry to here you having probs with your 4PL. Thats the radio I went too after having Spektrum for so long and dealing with there issues. Hopefull you get the problem sorted out.

Have you tried double collars? Or, an oring under the collar?

I run 7min qualifiers and 10 min mains and never have to pump more than 3000mah back into the packs. :weird:

Well a higher capacity pack also has a higher discharge rate with the same C rating...That would be my best guess, I run mostly at a friends backyard track so we dont have races that are a set time, mostly just a bunch of short races for fun.

I don't think this is correct. The "safe" discharge rate of a battery is listed as a C rating. The actual discharge rate will depend on a number of factors including motor, esc (and settings on both), driving style, etc. A higher capacity does not mean a higher discharge rate.

Yes, P=IV. But if you want to calculate the "instantaneous" P you are putting into your car, you have to take the battery voltage (let's call it 7.4V) and multiply it by the amount of current you are drawing, at that moment, from the battery (not the battery's overall capacity).

You do see guys get excited about high C ratings, and insisting that they get more punch with higher C rating. I suppose this is possible (and this would also reduce instances of brownouts, as the battery can always keep up with the demand). This makes sense if battery construction for high C ratings ultimately lets more current flow during bursts.

Evil get the Gens Ace. They are what 25-30 bucks.

Believe you me I've run them hard and they work great for only 20c. Wish they made higher c rating batts.

Yes, I run that motor and have not modified my chassis at all.

A couple of things, though:

1. The ballistic 550 cans are different from the older HV 550 cans. HV cans may require a little chassis grinding or modification. Ballsitic cans do not. I think you are aware of the difference based on the wording in your post, but just wanted to reiterate it.

2. It is still a tight fit. I have to slide the drive shaft through the motor mount hole and kind of "click" or "pop" the motor timing endbell past the chassis. It's not a big deal. Once past it seems to not touch the chassis at all when positioned with proper gear mesh (32p gears geared 12/62, haven't tried higher pinion yet).

3. I do have a small wear mark on the chassis from the timing endbell. Don't know if this is from hard landings or from moving the motor around during mounting.

Hope this helps. I wanted to get a cool 4-pole, 540 motor but just couldn't swing the extra money when I put the truck together. I run the Havoc Pro SC X-drive/550 4.5T and I am happy (but I am not a hardcore, experienced racer).

I'm not an expert on batteries, but just to clarify (or start the discussion, if it can help me or others), I think I am with Keddy on this one. The capacity of a battery, x-thousand mAh, is really just like the size of your gas tank. An R/C with a 6000mAh battery will run longer than with 3000 mAh just like a car with 10 gallons of gas will run longer than it would if you only put 5 gallons of gas in it.

Right for the most part. The key is that the voltage is constantly dropping the whole time. Lets say your car uses 2500 mah in a 5 minute race. With 30 seconds to go this puts your 3000 mah battery at ~7 volts nominal while the 6000 mah pack will be around 7.5. Assuming that the voltage doesn't dip under load at all (infinite C rating), the 6000 mah pack will provide almost 10% more power. It's not just that, your lines would have to change as the race went on to compensate for your continually dropping power and consistency is what wins races.

I don't think this is correct. The "safe" discharge rate of a battery is listed as a C rating. The actual discharge rate will depend on a number of factors including motor, esc (and settings on both), driving style, etc. A higher capacity does not mean a higher discharge rate.

A higher capacity absolutely means a higher discharge rate is available. What we are really talking about with C ratings is how much current can the pack deliver without the individual cell voltage dropping below 6 volts. A 10c pack can deliver 10 times the capacity (in mah) without damaging itself. A 3000 mah 10c pack will give you 30 amps continuous, but a 6000mah 10c pack will give you 60 amps without hitting the lvc prematurely. A 6000 mah 10c pack will be holding a higher voltage than the 3000 mah 10c pack at 30 amps, so the 6000 mah pack will provide more current, voltage, and 'punch'.

Yes, P=IV. But if you want to calculate the "instantaneous" P you are putting into your car, you have to take the battery voltage (let's call it 7.4V) and multiply it by the amount of current you are drawing, at that moment, from the battery (not the battery's overall capacity).

See above as to why the voltage will be higher with a larger capacity pack.

You do see guys get excited about high C ratings, and insisting that they get more punch with higher C rating. I suppose this is possible (and this would also reduce instances of brownouts, as the battery can always keep up with the demand). This makes sense if battery construction for high C ratings ultimately lets more current flow during bursts.
