All is good with this car. I swapped the links around. I had R&R'd them so many times trying to get the right amount of clearance (they wanted to touch one of the contacts on the motor) and I ended up putting them on backwards. Derp. I am happy with the 16t, totally. When these burn out I'll go for a 20t just for more low end control, but I probably won't notice the difference. On 3s, this thing tops out at maybe 15mph? 12? Faster than I can run most likely. On 2s, it is a bit more sane. I still can't decide which one I like better. The 3s is 75c, and the 2s is 40c ... Are the U Joints just tighter? More durable? I have not had any issues with the axles it came with. I'm trying to imagine a situation where play in the axle matters ... I don't remember what foam I got.

Oh yeah. 16t crawlmaster sport motors. I should have gone for the 20t I guess. Once I dialed in my control stick's d/r curves, I have all the control I want really. s

I had thought the Bully II axles were much improved upon the originals? Or is it the CVD thing as Stimpy suggested? Yeah, I know about the rear links. I kept bending them and reinstalling them, just a little at a time to get the motor clearance I was after, then I installed them backwards the last time I guess! I keep meaning to get around to it, but I have a couple of stripped bolt heads. Cheap tools and cheap screws I guess. Time to grab the rotary tool ...

Here you go ... I don't have any pics of it on the rocks as of yet, but here it is. Except for 4WS, the mechanical stuff is all stock. I did wrap balloons around the shocks and installed some knuckle weights. Electronics are labeled in the wiring diagram. I am pretty new to the hobby so I started with budget electronics and will upgrade if anything feels lacking. So far everything feels outstanding! I don't know that expensive electronics will make much difference at this point. It is a real beast! I control it with dual sticks, throttling and steering each axle individually, front with the left stick and rear with the right stick, negating any need for a dig. Everything works fine without an external BEC. The ESC's are each rated for 7.4v, 3A, and the servos stall at 7.4v, 2.4A if I remember right. When these motors eventually wear out, I will get slower, torquier ones, as it is WAY too fast on 3s. Even 2s is a bit much for this crawler. I am able to adjust curves with my transmitter though. STARSCREAM'S BATTLE FORTRESS! My 4 year old had a $50 gift certificate and she got me this. I finally found a use for him!

With this being my first real crawler, I went with a Bully 2 kit and cheap electronics. I went with a radiolink ts8 transmitter which required a radiolink 4 channel receiver. No OpenTX for me, unfortunately. I was aware of it and am a certainly open source guy (I run Linux), but I wanted cheap. The radio does do mixes, but I can't actuate them with the switches. The radio does allow a lot of programmability, but alas, the only things that can be switched on the fly like that are D/R curves. To slave one channel over to another, I would have to whip out my phone and do it there. All that being said, the morning after creating this thread I switched back to my original scheme (front axle all on the left, rear axle on the right). I discovered that the whole switching things around like that, and perhaps sleeping on it, actually reinforced what I had been training myself to do over the last week. It suddenly felt natural! I have really started opening up what I can do with this little beast. I may be converting my little Basher Rocksta (Stingray) over to the same receiver, but I need to find a tiny (enough) ESC I can fit two of, along with the receiver in that tiny chassis. Luckily it doesn't even need drag brake because the thing is so light, the gearbox itself keeps the wheels from spinning. I guess whatever thumbnail sized 4 amp or more ESC has the best low speed control ...

I think both of these examples are with using a pistol style transmitter though, right? With a stick transmitter, you independently control each servo and esc. I have gone back to my original config, as I think I am most comfortable with it, just takes some getting used to.

Hi Everyone, I have an MOA with Dual ESCs and 4WS. I decided to go with dual sticks and a 4 channel setup because of the level of fine control it allows. This is my first time doing such a thing. Here's my issue. Because it made the most logical sense to me, I started off by going with the following scheme: LEFT STICK RIGHT STICK Front Servo Rear Servo Front ESC Rear ESC ... Initially I found that the steering felt a somewhat backwards (I guess because I am used to turning the wheel with my right hand to control the front steering on my X-Maxx), but I stuck with it for a week or so. Today I found that I was still mixing up the throttle channels, resulting in disaster on the rocks. Perhaps unwisely, I decided to reverse things as follows: LEFT STICK RIGHT STICK Rear Servo Front Servo Rear ESC Front ESC ... This made my brain happy as far as throttle goes, but I guess I had trained myself (formed the neural pathways?) by this point to like the steering as it was originally. My brain was starting to feel the stress. I then tried this insanity for about fifteen minutes: LEFT STICK RIGHT STICK Rear Servo Front Servo Front ESC Rear ESC ... The idea (I guess) being that steering is "supposed" to be done with the right stick on a standard 2 channel setup. My brain was indeed happy with the steering and throttle for a little while, at least tooling around on the living room floor, but it was just too weird when I got on the rocks. Stress fractures began forming on my cerebellum. I then went with this idea: LEFT STICK RIGHT STICK Rear Servo (REVERSED) Front Servo (REVERSED) Rear ESC Front ESC ... Again this makes the brain happy on flat surfaces, but once again is too weird on the rocks. At this point there are clear fissures across my cerebellum and my frontal lobes are starting to overheat. I am now back to running this: LEFT STICK RIGHT STICK Rear Servo Front Servo Rear ESC Front ESC ... And I can't decide if I like it better than the original setup. My gut tells me I should stick with this because I initially found the original setup's steering backwards and I just need to untrain myself. There is smoke coming out of my eyeballs, my ears, and my ass; I now have permanent brain damage. 😱 I guess my question is, how do YOU control your MOA 4WS crawler?
