I'm rebuilding an old 10T with my boys(4 and 6). I want to go brushless with it and was wondering if a 21.5 turn would have too little power. They're both already driving RCs. They run a 17.5 now without problem in a buggy. I just came across a good...
Last post
21.5 is around RS-540 speed. I thought it was a good fit for my 4 year old. One thing I noticed (at least for my kids) is that if you reduce power, they don't seem to notice and have just as much fun and you won't have to fix the car as often.
So I have a servo that for some reason when in the car wont center. when I pulled it out afterwards, it centers again. any ideas whats going on?
its a LHS ls-500 bb mg servo
im already replacing it with a savox servo but it still seems like its...
Last post
yep, could be binding in the suspension. also, load the servo with your fingers while you exercise it on the bench, and see if adding some load to it prevents the centering. usually bad centering is the travel potentiometer. you could disassemble...
I have the Airtronics 2.4Ghz FHSS-2 3CH Receiver -MX-4 .. I think I'm held to Airtronics only receivers.. I have the RX37w that goes for around 48 bucks.

Yea my search came up with nothing. You have to use the AirTronics only. Got one from Ebay for 40. The last one I got from Amain for 49 when they came back in stock.

So I'm looking at savox servos and I noticed that I'm seeing servos with the exact same part numbers as those from turnigy. there arent many exact matches but they are all close to each other through the whole line.Can anyone one say whats going on...

Finally had to ditch the old Protech! Lol! This charger will charge anything I will ever own, but it's going to take me a while to remember all this charging crap!

I apologize in advance for the generality and newb-ness of a question like this but I don't really have the off-road RC experience to know whats what. I'm going brushless, lipo, etc in an RC10 runner build and I'm ready to order a motor. I will go...

Thanks for the replies, I did wind up ordering a 10.5. It sounds like it'll have all the potential I could want, I figure I can gear it 'slow', see how it runs and go from there.
I just installed this ESC, in my recently build RC10WC, coupled with a reedy 17.5T mach2 540 motor and I have the following 2 issues which I am hoping someone could help answer for me:

Mk-zero has a valid concern though. Yes the side has graduated measurements, but the device really needs to have an adjustable down stop in order for it to be truly accurate. Otherwise one will be eyeballing all of the springs measured with regard...

The lighter weight of the shorty battery will have less weight on the tires creating a smaller contact patch for less traction, also there is less overall weight transfer (but faster) during braking/acceleration/turning. But pretty much everything...
Since most sensored systems only spin one way and most competition ESC's don't allow you to change motor rotation - what would happen if you swapped A and C and wired the sensor cable backwards?
I assume the timing would be backwards/retarded and...
Last post
If the motor timing is set to zero and the A and C sensor wires in the sensor lead are swapped over, then the motor will run backwards the same way it would run forwards. The only problem is that not all motors will give you true zero timing, and if...

Just my $0.02, but in lightweight buggies, I like the high speed shorty servos. The Savox SC1251 is excellent, but if your budget doesn't quite allow for $65, I've also been very happy with the HD series that Atomik RC slings on their eBay store. I...
So just wondering if anyone on here has used the Hobbywing 90A V2.1 esc and how they like it?

Stick to the genuine article if you can, the 90 is good but if you can afford it get the 120. I've used both the V2.0 and V2.1 120A ESC's without trouble, and the V3.1 which is amazing.
What´s the main differences between the V3.1 and the older...

The speed sensor is cool, it transmits what ever light it needs. The radio system came with reflective tape, I just put a little strip of it on the drive cup. Then you have to position the sensor to within about 1mm of the target. To calibrate it,...

I see its relatively easy to find an ESC capable of handling 8s for trucks/buggies etc. But I'm not finding any 550 motors capable of handling 8s without going to a heli or plane motor. Any suggestions? I'm trying to build a horizontal missle! :lol:
Last post
why not go a heli or plane motor? or even a boat motor...those things are made for 100% throttle/load all the time.
They don't have to deal with the extremely heavy low RPM loads, and are not designed to. In a plane or boat, there's practically no...

You may need to play with trims, or adjust neutral range.
There's nothing wrong with the XP2 or XP3 2.4 GHz systems, they're actually pretty decent for RTR stuff. Certainly not as good as a Futaba or Airtronics, but not bad.

Have you made sure the harness is not flipped backwards on the 3 pins of the esc? With the sensor plug and harness pins facing you, the far right pin of the harness should be the signal or white wire, middle is red, left is black.

I swear by the Hobbywing V3.1 and whatever motor fits into your class. The V3.1 really shines when you start introducing dynamic timing, but also seems to have more power in blinky classes. It also has the smoothest power delivery of any ESC that...
