if your range settings on your throttle are normal (on your transmitter), pop your ESC into program mode and set the range of your throttle again

Would this be a timing issue in the ESC programming options?

No it's not the timing - that's the "phase lead" of the pulses, and generally you don't need to adjust it but for large, high torque motors, low timing seems to work better. The problem you're having is the expected throttle signal has less range than the actual throttle signal, so it tops out early. You just need to calibrate your ESC to recognize the true channel range of your radio. Teach it the end points. Most ESCs have a way of doing that, but without knowing what you're using it's impossible to say how to do it.

Hi Jasmine2501,

Thank you so much! Okay, so I'm using a Turnigy Plush 40A ESC with a Suppo 2217-6T motor. Prop size is 8x4 and my battery is 3S 2200mah. My Transmitter is the Futaba 9C. If you need any more information, please let me know. If not, can you please tell me how I can adjust the throttle range based on the above info?

Your help is much appreciated.
WJ

Plush is a solid ESC, I use them on a couple planks... they are easy to program, but this information does seem to be hard to find. You can get a programming card from HK if you want to set the timing and stuff, but for the basics, you can do it with your radio...

NOTE: With Futaba, you may have to reverse your throttle channel if you haven't already done that.

Thank you jasmine. I have the programming card. Any way I can set the throttle range with the card? I don't know which feature on the card refers to the throttle range.

No it doesn't work that way - you need to teach it what your min and max looks like. Every radio is slightly different between brands - keep in mind we're still dealing with analog (PWM) signals for the servos, so slight differences will crop up and the ESC manufacturers have given us a nice way to deal with that, by simply teaching the ESC what to look for with a particular radio. It needs to actually observe the PWM signal coming from the receiver - to measure it exactly. The programming card can't send that signal, only your radio system can.

Try to recalibrate your throttle in the rc tx

Make your throttle trim at mid point before you do this

For ground testing use small lipo that is low in volts to be safe

It's nice also to have a 1/4 or so dead band at bottom of throttle so you can move throttle stick when in bottom position and nothing happens

If you get motor jitters in transition to motor on from not being on adjust the trim on the throttle

Programming the esc is usefull
Especially if you want longer or better efficiency less power less heat

Or the opposite most power and least efficiency

I am pretty sure simple re calibration in the rc tx will solve your problems
You should also be able to calibrate it to out put 110 percent rather than just 100 percent if you want to maximize out put

Throttle curves are great to make in the rc tx as well

Today I discovered that Fatshark Dominator goggles are unfortunately affected by a disturbance generated by the Dragon Link module.

Specifically, when I power on the DL module the video displayed in the Dominator Glasses undergo a significant disturbance... the strange thing is that, simultaneously with the glasses, I watch the video on a TV in front of me, which is not contrary to the glasses minimally affected by DL module.

In short, the Dragon Link creates a disorder that affects only the video displayed in the glasses and not the rest ...

Have you advice for me on how to solve the problem?

thanks

Are you 100% sure? Many guy's have been using the Doms with DL and I haven't heard such a thing. Did you get a chance to contact Mike (user: JettPilot)? He is the manufacturer of DL. Also, maybe take a look at the DL thread and see what the guys on there are saying. Furthermore, are you using the wireless 5.8ghz module on the Doms when you're getting the disturbance?

Thanks David, I will give it a try. I just quickly glanced through my Tx and noticed that the Throttle end points are 100(down)/100(up). I'll try to play around with that to see if that changes anything. I'm assuming that is what you mean by calibration in the Tx?

Thanks Jasmine. Clearly, I got a lot to learn in this hobby still

That is what makes it such an awesome thing to do - you can never learn everything. That's why I do it - because I like the mental challenge.
