Some time ago I made a simple RC transmitter ( uno + nrf24l01+ 2 analog joystics) to control a RC car ( pro micro + l293d + nrf24l01 ).
It was working well, but now I am building rc plane. On transmitter side to increase transmitting distance I've changed nrf24l01 into same chip but with power amplifer + 9db antenna.
On receiver side I'm also using arduino pro micro + nrf24l01+pa, where D3 pin goes to ESC (throttle), D5 and D6 pins are connected to RC plane ailerons.
At a moment this project has some major problems, so there are my questions:
- is there any need to use nRFl01 + power amplifer in receiver side? (I've set AUTO ACK to 0). transceiver chip without antena will be smaller and lighter
- Is there a need of additional 5v>3.3 converter on transmitter side? I'm using 3.3v arduino pin, and measured current, RF module consumes not more than ~11 mA
Thank you for advices,
there's how the plane looks like: youtube link
