Good eyes, did not notice one winglet was bigger than the other. cya

True. I think the dyson is a reach, but proplematic, meaning you would have to do the research. As for horizontal thrust of the winglet, it is angled to do that. The RCModelReview, which is a hypothesis, says that the centrifugal force of the high pressure air is deflected in the direction of...

Random grab. ISS uses minimum noise fans(Prandtl Propellers) in there computers so the Astronauts can sleep. Also Dyson bladeless fan uses Helmholtz cavities to filter certain noise frequencies. What if the fan was inside the body of the aircraft(with noise silencing). This has a 15 times...

Also found the video about no rudder. I thought it was TED but it was NASA. and

Thanks. I will check it out. BTW I found the RCMODELREVIEWS article I mentioned. He mentions an autogyro with Q-tips. Looking at the thumbnail photo the curve at the tip is two dimensional. So my attempt seems pretty random.

Thanks. I already have some spares.

Thanks. Worth a shot. I know about the winglets on planes, the Boeing737Max are still redesigning them. See Boeing: The most efficient winglet on any airplane Also I have seen some TED talks about reversing the camber so you don't need a tail fin. Just like birds, soaring Eagles do it best...

Hi All, I have a Mavic Pro series 1. I bought some low noise propellers(Platinum) for it. After about 10 flights I noticed that the tip was bent down. Probably from storage and still having a hot heat exchanger under the quad. I had watched a youtube video years ago from rcmodelreview about...

I am not sure we have good speed information. There is a speed number on the remote control and a horizontal speed in the DJI GO App. They are always different. It the horizontal speed is calculated using GPS then what is the minimum time interval between consecutive readings. Then assuming your...

There is a bit of redundancy on the AC but none on the RC. Is this a case for a second RC. Or should DJI build a second RF circuit into the RC. Regards

Thanks Sar. I now remember you saying that in a previous thread. Do we know what type of encryption. RSA? if we could find the certificate we may decode it. Can the data from the fc be downloaded to the phone. Hence decrypted. Eg. Do a flight turn RC off(or just the phone). After the AC lands...

Met4 the data analysed from the phone stopped when there was a signal loss. If there is data from the DRONE after the signal loss to the RC/Phone then it wasn't a power failure. Did it reset the home point and just land. Probably not as the AC was wrecked. Some have reported a shutdown due to...

Wait. What. No. It's not over. Can you upload the flight info from the DRONE. We have not determined if it is a signal loss or power fail

True. They need three imu/compass. Error correction(3) verses error detection(2).

Bear in mind that some battery packs have a fast charge(2C) as well as normal(1C). I have a lithium battery pack that can take 30C continuous or 60C Max burst. That must produce some heat.
