Have tech questions? Will answer.

I wonder if it’s just not strong enough, and that’s where it ends up. My Futaba and vanquish dig work well with a full sized servo as recommended by VP.
Doesn’t make sense to me as my dig was simple to set both switches to work as needed.

The HS-5070MH is a beast for a true sub micro servo (its literally the same size as the Spektrum recommended servo) and at 7.4v puts out 53+ oz.in. of TQ, should be plenty to shift the dig fork I would think, unless something isn't correctly assembled in the transmission.

It's more than strong enough...it's equal to, if not somewhat better (and slightly stronger) than the Spektrum SX107 Axial/Horizon Hobby recommends. As for the switch settings, those are correct, as shown by the DT switch correctly controlling a standard servo that I plugged into Ch4. Besides, as I mentioned, while the (less powerful) Traxxas micro servo also wouldn't function on Ch4 (DIG), it did function on Ch1 (steering). It's just "strange" that the Traxxas unit also doesn't work on Ch4, but it does work on Ch1.

Unless I receive suggestions to try from John, or other people in here, I might have to wait until the replacement arrives. I did find the Spektrum SX107 (I had temporarily misplaced it), but don't have time to test it out today...that will have to wait until tomorrow, or Tuesday (which is also when the replacement Hitec should arrive). I'm also expecting a callback from one of AMain's techs tomorrow morning, after he talks it over with one of the other techs (who wasn't in on Friday) who's supposedly quite familiar with the 7PX.

As much as I don't want to use it, if the Spektrum unit works, and the replacement Hitec doesn't, even though the Spektrum is only rated up to 6V, I may keep it...tho, running it at 7 4V will probably shorten its life (at $15, if I have to replace it every 6-12 months, so be it...at least until I can find a strong enough digital micro servo that is rated for 7.4V).

I have a stupid question: can I plug lights into the bind port of a reciever?

 

[JohnRobHolmes]

You can plug lights into a bind port.

For the servo issue, be sure the horn isnt rubbing the case. Also, see if you can make the radio output a signal for analogue servos instead of digital for that channel. The micro servos might want a slower signal frequency.

Thank you for the quick reply

The Hitec HS-5070MH he is trying to use is digital

The horn isn't even attached (not attaching it until the second is functional, and it's 'centered'. As for the channel thing, if you read what I've written, I've tried both digital & analog servos. Additionally, under the "Receiver" page, I've tried both digital, and analog, signals...hasn't made any difference. Lastly, unless you know something I don't (and, that is possible), I don't believe you can set a transmitter to transmit digital signals to certain channels, and analog signals to other channels...it's one, or the other.

[R/C controls YOU]

You will be fine with the crawlmaster, even though its 10t it is closer to a 21t in esc load because its five slot. It will be a shade faster than stock, pretty close though.

A torquemaster pro will be over double (about 120%) the torque of stock. A crawlmaster pro will be right at double.

6 degrees timing wont affect your drag enough to notice.

Thanks for getting back to me so FAST! Obviously not Traxxas-fast because they’re the fastest name in R/C. :twisted:

Ordered the CrawlMaster Pro 550 10t. That should REALLY be noticeable with the extra axle & weight of the TRX-6.

I've got an update on the DIG servo problem I've been having, and it's a very high probability that the servo is defective. Even though the Traxxas 2065 also wouldn't work, I'm going to make an assumption (possibly correct, possibly incorrect) that it's because it's analog, or because it's much lower in torque, or because it's not actually a micro servo (it's a sub-micro servo), or any number of other reasons. Truthfully, I don't know. The Traxxas servo works on Ch1 (steering), but not Ch4 (DIG)

Anyway...here comes the 'plus'...I finally found the SX107 I'd originally purchased as a "backup" for the Hitec servo (if the Hitec didn't fit, which it did). First, I plugged it into Ch1, just to make sure it was operational...and, it was. Next, I plugged it into Ch4...and it's operating 100% spot-on. As such, I'm 99.9% certain that the problem with the Hitec 5070MH, from the beginning, has been that it's 'defective'. AMain shipped me the replacement this morning, and it should be received tomorrow.

Hey there. I have a Vaterra Ascender with a Hobby Wing WP1080 and a Hackmoto 35T motor. For the most part this seems to have been a decent combo, but when on a 40 degree slope or so, the truck will roll backwards when the throttle is released. The truck is heavy as I have added the SSD Knuckle weights in the front and the SSD axle weights in the back for a total of almost 10 ounces (280grams). It also has fairly heavy solid aluminum 1.9 wheels. I have the throttle trim set to neutral, but have adjusted it with no real improvement. I have played with all the settings on the WP1080 and just cannot seem to get it dialed in.

Is there something wrong with my setup that needs change? Is it just a function of a heavy truck? Should I change motors, and would this even do anything. It is getting a little frustrating and I would love to be able to get it working correctly. Other then this the truck is a great crawler.

Many thanks in advance.

Drag Brake and freewheeling adjustments are needed

Hang up and Drive

-Max brake force set to 100%,
-Initial Brake force set to 0%,
-Drag brake is set to 100%,
-Drag brake rate is set at level 9, but has been tried from level 1 to level 9,
-Freewheeling has be tried both on and off.

Not sure what else to try.

Hackamoto motors don't have the strongest magnets. Gearing down will help with the breaking so will a motor with stronger magnets. Volt up or get a lower turn motor to regain the speed.

heavy rig, gearing, and low quality motor are all at play. As VDB said, better motor or more geardown will help.

DIG servo problem resolved. While I still can't explain why the Traxxas 2065 worked on Ch1 (steering), but not Ch4 (DIG), the replacement Hitec micro servo arrived yesterday. First thing this morning (ok, technically third, as making coffee was first, and getting yesterday's mail was second), I tested the replacement servo, and it's functioning 100% spot-on.

Simple one- difference between puller pro standard 4500kv vs puller pro r 4100kv 540 L. Apart from that 400kv difference? Which to go for sumthjn like trx4 or wraith n looking for trailing speed plus good crawling torque.

Forgot one more option to mentioned is Trailmaster pro BL 4500kv as I currently run 2700kv on element enduro and luv it and puller pro from what I read should hav better torque and smoother starts?

It's on the website
540L is a racer motor for Extreme use
Better materials and same smooth start-up
There is also a motor recommendation chart on his site.
2700 or 3500 puller pro for Wraith Bomber

Thanks everyone. My suspicion was the inexpensive motor as well. The speed with the 35T is plenty fast for my needs, so I am fine if it was a little slower if it gains me better crawling performance. I would rather have a super smooth runner at lower speeds and good a drag brake. If it can go walking speed I am fine with that.

Recommendations? Seems like the 5 slot motors are the recommended items these days. Thanks!
