Servo pulling too much power?

[AjDale]

So I’ve got this maxx V2 I’ve made pretty beefy. I had a Hobbywing quicrun 8BL150G2 2000kv combo. No matter what I did every time I gave it throttle it would creep forward then have full throttle but would still hardly wheelie as if it wasn’t getting a good connection or something. I’ve seen videos of the maxx v2 doing a standing backflip and mine won’t come remotely close to that. I have swapped motors, esc’s, multiple gearing changes as well as rx/tx. I have a censored combo on the way but after thinking about all this I’m starting to wonder if my steering servo could be drawing to much power causing some kind of shortage to my motor/esc as the steering servo is the ONLY thing I haven’t tried to change yet. Waiting for my new max8G2 2250kv combo to arrive and test. I also ordered a new steering servo to have on standby and test as well. Pretty confident I can get this figured out. I just want better/more throttle response!

Have you checked your punch settings on the ESC?

If the receiver voltage (or bec voltage) is dipping whole under throttle (load) it could be that the servo can be pulling power. Stock servo? If so most likely it shouldnt be pulling much power.

Id try to add a glitch buster cap to a empty spot on the receiver and see if it can help.

Or can also be that the tx has a signal drop causing it to go full throttle and then back to normal when it regains connection.

There's a lot of variables that can be taken into consideration.

Also just wondering what Rx/Rx did you change too?

That's easy enough to test. Unplug the servo. But yeah, it can happen.

You sure you don't have a bind in the drivetrain?

Of course. I have a program card and everything.

It’s is doing exactly as you described. It is not a stock servo, it is a eco power WP250T.

I'm not sure if I know what a glitch buster cap is but I’ll look into it!

I am running the DX5C transmitter with a SR315 receiver just like in my XRT running a max5 1100 with a 2085R servo.

I swapped it to a dumborc transmitter and receiver with the same issue.

Zero bind in the drivetrain. One of the smoothest rolling rigs I’ve owned.

I will be unplugging the servo and testing. It currently does not have a motor/esc combo in it as I got mad and sold it to buy the max8G2 combo

Glitch buster ordered, I appreciate this suggestion. Beats spending another $100+ on a steering servo if I don’t have to!

You could unplug the servo and test to see if the lag goes away.
Just test in a open area so you don't smash without your servo hooked up.
A couple tries should tell you if you're on the right track.

That’s the plan! I have a new motor/esc combo coming for it because I thought of all this AFTER I spent the money and sold the old combo you live and learn I suppose. Once I get the max8G2 combo installed I will try give it a try and see what happens, next step would be to unplug the servo then add a glitch buster to see if that will help at all as well

I misread your post explaining your plan.
Well, at least you'll have lots of new electronics to play with now!

No worries! That’s one way to look at it, guess I’ll have to invest in a roller
