Hello Everyone! Thank you for subscribing to my channel and for your continued support and feedback! Here we look at a situation that would make tuning a nightmare, or like me, flying impossible. Hope this can help someone. Enjoy the Breeze...👍🏻🍻👊🏻

@MCsCreations Жыл бұрын

Yeah, those arms didn't have nearly enough carbon. Pawel Spychalski uses to fly 7 inchers and he said you need at least 6mm carbon arms. And probably a bit more thickness as well. Anyway, I'm happy you fixed it! 😃 Stay safe there with your family! 🖖😊

Hey MC's.. Hope all is good.. Yeah, back when I built my first 7incher, I went with the Iflight XL8. It's a nice frame but discontinued...

@zero-voltzfpv5715 Жыл бұрын

I have a build I could not get to tune due to a huge resonace at 70hz. I'm convinced it is the frame design. It has a large hoop on the front to accommodate a insta360, kind of the same situation where it just flops all around

So frustrating! I so wish I would have found out sooner. Hopefully this video will help people like us from having to go through all that aggravation..

@andrebalsa203 Жыл бұрын

Clearly a resonance issue caused by a lack of rigidity of the carbon frame, as your excellent investigation shows. And indeed this will have a complex interaction with the gyro. Excellent video, thanks for sharing !

ive been having problems with my 7" Super G+ for over a year. I have such violent vibrations the footage is just not worth even reviewing. It is especially bad in the FPV feed & I have done everything I can think of to get rid of the oscillations. Therefore, I have installed it in the storage unit. Boy has that old school build chopped some weeds. Thumbs up!

@airfriedquadsbw Жыл бұрын

I came up with a way to put the frame under tension without cables. It even reduces weight by a little. Tension reduces vibration, or raises the frequency of the frame, thus reducing problematic noise. Flights are so smooth and stable and cool to cold motors. 🥶

@propsoff Жыл бұрын

That sounds cool. Do you have a video? I don't allow links in comments but you could describe were to see it...🍻

Very informative, thank you. Not something you would expect from a decent frame design. Would have drove me mad. This is one going on my 'check 1st list' for sure 👍

Absolutely, and yes, it drove me crazy and I really began to dislike the whole idea of it; However, I'm super happy to report it flew amazingly yesterday! I finally got to FPV maiden this ripper. The CNCmadness V3 with 7mm arms has little to no vibes, Hooray!

@MatthewTaylor3 Жыл бұрын

I can attest that what this man says here is the truth. I got the SAME issue with my V4 version of this frame too. It burnt up an ESC, and heat up my motors. When it flies, it sounds like a motor with bad bearings the moment I reduce throttle.

It was embarrassing how much time I spent and the time of others. Unfortunately... But its flying like a dream now...🍻

A number of 7 inch frames with narrow arms get lateral shakes such as Tyro 129 but don't get handling issues . I would look at filtering or perhaps too much motor run out before blaming the frame. Does look dodgy though.

+1👍 💪 i recently 3d printed a crossarm (thick) for a similar problem, worked pretty fair. carbon crossarm would be better than 3d print; however, give it a try. the only way to get a thick crossarm in my opinion is to integrate a skid.

do you think its the V4 that is poorly designed, or is the carbon not cut properly? I have the 7inch V3 in my cart perpetually

@propsoff Жыл бұрын

I don't think it's the design, however, I wouldn't put 2807 motors on it. For me, the quality of the carbon was bad. The V3 provides more protection from the beating I'm going serve too, I do like the V3 design.

I'm not sure what to think about the design. I was really going after a lite build and the design may be fine. The carbon was not. Still, I don't think I would put 2807 motors on that frame. Maybe some pancakes for endurance.

I still haven't got to FPV the new frame, but the Blackbox and LOS was most excellent. I sort of feel exonerated. I just finished filming the install and effects of motor insulation pads. It was a little surprising of how it changed little to nothing, Lol. But maybe someone will enjoy me wasting my time and find it interesting too. Enjoy the Breeze...👍🏻🍻👊🏻
