New Hypetrain motors major problem!

[woodystyle777]

Hi,

I bought some Hypetrain motors that are doing something very strange. When you give the quad throttle and take off.....the quad just spins out of control as if you had full yaw counter clockwise. I made a video if you want to see what it does.

. Go to :47sec if you just want to see the takeoff.

Anyways I tried these motors on my second quad that has completely different parts: escs, fc, everything. This time i took off very slow to just hover above the ground and it just hovered doing pure yaws to the left again.

In betaflight on both quads I tried reversing the motor direction. Betaflight saves correctly but the motors refuse to change direction. Even if you rotate the motors around the quads they still spin the same way no matter what.

Does anyone have an idea what is going on here? My older weaker motors work fine on both quads with both escs combination. I am using Betaflight 3.2.5 on both quads. If I just have a bad motor is there a way to test the individual hypetrains?

Quad 1:
betaflight fury f3 FC
Diatone 30A escs
Original motors: Edge racing 2205 2300kv

Quad 2:
betaflight f4 FC
DYS XSD 30A escs
Original motors: brother hobby R4 2206-2700kv

Don't believe the hype. Lol
Assuming everything is wired correctly try resetting the board & recal the gyro in the setup tab.
Then update the firmware for the esc again. Make sure the end points are the same for each esc in blheli configuration tool. I spent a whole 2wks on a flip on take off problem. After checking wiring resoldering it it needed was a board reset. May be worth a try.

Thanks for replying.....I'll def give your 2 suggestions a try and post back. I am under the impression that it is motor and not esc or FC just because after this problem I started taking both sets of my other motors and testing them both out on both sets of escs. They work fine no matter which setup they are in. After seeing them work on both quads I also start rotating them to different escs to see if maybe in a different order I might notice a problem but they both work flawless no matter what.

Just curious but if it was a gyro problem wouldn't it effect multiple types of motors? I would think the same with the escs.

Anyways I'll give it a shot anyhow because those 2 suggestions wouldn't hurt.

Thanks

Tazmanian Devil effect. What direction is the arrow on your flight controller pointing? A pic would be helpful

 

[mozquito1]

A bad crash the gyro can get stuck.
I can't see it being motors as what's to go wrong. Only 2 directions. Or a chopped wire. Motors work underwater so I don't think they are the problem. Are you using Dshot but only have one shot or multishot esc's. What it ticked in the configuration tab top right corner under esc protocol.
If motors go forward & backwards & stop there is nothing wrong with them.

 

[mozquito1]

Yes a picture would be great.

From the wiki:

Here are the most common causes:

• Motors plugged in to the wrong FC headers.
• Custom mix is incorrect.
• Motor spinning the wrong direction.
• Props on the wrong motor.
• Flight control board mounted facing the wrong direction (e.g. yaw 90 degrees left but the board_align has not been configured to reflect this).

Thanks for the reply guys....I'm at work at the moment so as soon as I get home I will give y'all the pics and info you need. I just figured it was the motors cause any other motors I put on there works fine. But it does make sense how basic motors are that it would be something else. I'll reply tonight

Thanks

Are you sure the motors spin the right way with the right props on take props off check the motor rotation

 

[mozquito1]

When you buy motors they either come clockwise CW or Counter clockwise CCW.
You could put the motor on in the right direction, but depending on how the esc is setup it could spin it the opposite way.
I don't bother with CW/CCW I just buy 4 motors & bang em on. Then just change the direction in blheli.
So if you put CCW motors on a quad,
if nothing has been altered it should run as intended. If you put them on a different quad then depending on how it's set up, the motors may or may not run opposite. I put some tape on the prop nut & feel the direction.

Sorry for the late reply:

So I tried everything suggested here. Some friends that have been into fpv also suggested the same things. I got into blheli and flashed the latest firmware (16.63 or 16.67 can't remember) and everything was successful. This was just on one of the two quads that was getting the same problem. Checked flight controller gyro direction. In blheli I even reversed motor direction so normal there. I checked individual motor mapping in betaflight.....all correct. I put the props on the right direction checked like 5 times just to make sure. Went outside with the updated quad and instantly crazy Yaw spin!!!!!

When I came back in I was bummed and sitting there fidgeting at a loss for words spinning the props with my fingers. I noticed that motor #2 was spinning just slightly slower than the others. So I believe it was the motor the whole time. I have taken it off to return and ordered 2 more hypetrains just incase.

I'm hoping this will be the real answer to the problem. 2 different quads that had two other sets of motors both flew properly. The variable in the situation was always the motors, making 2 completely different working setups have identical problems once the new variable was introduced.

Thank you so much everyone for your replys as soon as these motors are in ill slap them on and let you know if the problem was fixed.

Hi keep us posted on the out come

 

[mozquito1]

First time I've heard of motors governing there own speed. Did you try the board reset & not load any backup settings.
Too late now anyway.

 

[woodystyle777]

Not sure what board reset is

 

[RENOV8R]

In the Setup tab, top-left corner, right below Calibrate Magnetometer is Reset Settings. This returns everything to default settings.

 

[mozquito1]

On the setup tab @ top of screen in betaflight, next to gyro reset is board reset.. I suppose its just the same as reloading an earlier firmware then reloading the latest one back on.
Worth a try though. don't load a backup. Just set it up again yourself. A bit of a pain but atleast you know everything has been reset & the board is fresh.

 

[woodystyle777]

Ok update:

I reset my flight controllers like you said. Just to see, I put my stock Diatone motors back on my Tyrant S and went outside and did a small hover test. The quad hovered perfectly and moved forward backwards and sideways correctly to my commands. I came inside, took the hypetrains of my MQC fusion, and put them on the Tyrant S. Same problem no matter which quad. Both quads work perfectly with either sets of my other motors.

 

[woodystyle777]

Oh and also.........not only does it do full yaw, when you give it just enough throttle to get off the ground, it instantly goes into full throttle

 

[RENOV8R]

Obviously a problem with the Hypetrain motors. Send 'em back

 

[mozquito1]

Obviously a problem with the Hypetrain motors. Send 'em back

How can motors govern their own throttle though. & yaw with no input.???
Did you say you can change motor direction in blheli & did it work.
Without seeing this for myself I'm stumped. Send em back. You can't go wrong with some emax.
