Hello Everyone! Thank you for subscribing to my channel and giving your support and feedback! Here we take a look at insulating the 2807 motors from the frame. I personally don't think it was worth doing. What has been your experience? Enjoy the Breeze...👍🏻🍻👊🏻
Debunked thanks brother!! I like the term insulating versus soft mounting. I used to soft mount my motors back in the day when the betaflight filters were not as good. Nowadays the filters are way better so not needed. As always I smashed that like button brother 👍🤟🔥
+1👍 tpu or silicone motor-pads is essentially another "filter". silicone will take the heat and maybe softer material will absorb more vibes. tpu will melt if you allow hot-motors (racing). both will introduce variables because bolt-tightness will vary and possibly loosen more easily. better off with motors on frame, no pads. adjust software filtering as necessary. personal opinion is there is an exception: maybe use TPU motor-pads pads with 3D printed whoop frames.
I've had good results sorting out a vibration/resonance problem using multiple layers of electrical tape under the motors. Information found in a Chris Rosser video as well as explanations found in sn old NFE-related chat led me to avoid using any type of insulation material that is springy in its own right as to avoid rebound resonance.
@@PropsOff , yes I agree to avoid it as far as possible. I made the effort purely as an engineering challenge to myself, trying to revive an ancient Eachine Falcon 210 BNF which was a bit of a dud product many years ago. The insulation tape trick and a new FC got it flying smooth. The new FC made no difference, but strapping up the arms and under the motors with the tape got it flying smoothly. So yes, just a little personal victory over my resonance problem. I'm still going to replace the frame 🤣
The hole walls will transfer the vibrations along the screws to the frame in any case. Maybe you could try to dampen the vibrations from the arms to the frame with dampening grease.
I'll have to agree. If any dampening needs done, probably should be at the arms. This didn't do much, but I had to raise/max the gain of the BB viewer just to see anything, lol. So I'm pretty happy...🍻
Rpm filtering negates the need to soft mount or insulate motors now a days. I was surprised to see this video was released four days ago and not four years ago when the bolting insulation under the motors was a thing. Are you familiar with rpm filtering, you should look into it, it will make a huge difference in your tune
The resonance variation between motors, arms/frame, and hardware types and torque are already enough, adding any more variables is just asking for trouble. Especially when they come with the possibility of making things slightly better or significantly worse. I use Teflon grease and titanium if I want a little soft filtering, that’s it. I went down the soft mounting rabbit hole and gave up when I realized that the EXTREME finickiness is not worth the improvement. I recommend playing with motor screw torque, skipping the loctite and using grease instead, but… If anyone want to change something beyond that (assuming all parts are good), go in this order: prop, check for electrical noise and fix, motor hardware and torque, frame, motors. Going further is unnecessary unless you like collecting very precise data for fun. Been there, done that.
I like that, "extreme finickiness". That about sums it up for me. I never mentioned torque the screws is best, I agree. I appreciate your feedback and details...👍🏻🍻👊🏻
@@PropsOff It IS very finicky, if the torque has to be so low that you have to “glue” the motor screws with red loctite or similar, preventing maintenance and making everything a pain, or using a precise $300 torque wrench every flight. Yeah… that’s extreme for me :p and I am tolerant :p Even torque is important, and different torque values make almost as much difference as soft mounting.
Soft mounting sounds like a good idea, but as you show, it can add a resonance you aren't expecting. I played with a few ideas tying to dampen vibrations in the arms. None really helped.
Insulating / softmounting motors never brought me anything either, the times i did it. Didn’t look at black box, but just how it flies. No difference. Maybe it helps if you have issues in a motors or with motor vibrations 🤷♂️
Pretty interesting experiment indeed, dude! 😃 But yeah, I bought a set of silicone soft mounting for motors a good time ago... But never used them! Never needed. 😂 Anyway, stay safe there with your family! 🖖😊
Seems like the time and money should have been spent flying for me, Lol. I'll probably remove it all and chalk it up as a learning experience. Wow, Betaflight has come such a long ways too.. Enjoy the Breeze...👍🏻🍻👊🏻

better off with motors on frame, no pads. adjust software filtering as necessary.

I'm going to agree with you. I'll most likely be removing them before I fly again. Enjoy the Breeze...👍🏻🍻👊🏻

It would be interesting to build 10 different quads and insulate test. However, it does seem useless...

yea..I never gave too much thought to specifically soft mounting motors but do use tpu spacers sometimes if my bolts are too long....👍🏼
🖖🏼
That's one thing too, soft mounting basically will force me to Lock-tite all the motor screws. Probably coming off soon, Lol. .🍻

I appreciate your feedback. I have the motors soft mounted on my Rescue Drone and never much thought about it, lol... It was the thing to do, then..

I really think it was a waste of time and $8 bucks...Lol
@@PropsOff Not a total waste. Now it's out there for people to know :)

I actually debated trashing this video, a double waste of time. But was interested in everyone's experiences. Enjoy the Breeze...👍🏻🍻👊🏻
I experimented with that idea too, but didn't get any improvement.

Try unleaded instead of diesel
True Blue...🔥
it's not woth it ! i have made this in the past and motors are getting loose over time
I pulled them out, definitely a waste of time and the data to back it up. I appreciate your feedback...🍻
