When i swap to setting menu in tello app, there is one thing in the bottom named as bitrate which is auto by default. if i switch to 4mbps, will my video quality and frame skip improve?

The bitrate is related with the transfer capacity between yout tello and your phone. If you set it to very high value the image quality will be better but if the connection is not able to trnafer all data you will skip frames. If you set to low values... images will be worse but it will be more difficult to skip frames. I hope this clarify your question.

If the wifi link is "bad"... you need low bitrate to avoid frame drops, if the link has good quality you can use hisger bitrates. The auto mode will select the best options for you depending on wifi signal strenght, so Auto.

In addition to the bitrate question: no manual setting will stick, so it reverts back to Auto the next time you connect the app to Tello.

Would like to see a higher than 4mb rate. I don't fly far, video quality is important for me. a option up to 10mb or ever 7 or 8 would be great

I am not an expert but I think 10mb is more than is needed to transfer all the data that is in a stream of frames. Always using it would not do anything other than to increase the risk you will miss one. As a mad idea and to prove me right or wrong you could look at the average size of a frame and then multiply it by the frame rate and see how many mb's are needed for continuous transfer.

Agree with the others that using an extender has to be the first thing to do.

Edit: Actually, maybe stuff other than the image stream is also transmitted back and also I wonder how it sits with the control signals you are sending up to the Tello. Is it a duplex channel - any handshaking etc. - help, we need an expert ;)
