• can/should we fly without an imu? I2c pins 2/3 for micro
• Cheap micro brushless motors aren't as easy to find anymore...
• Using the L293D as the motor driver it needs 4 digital pins and 2 pwm for speed control.
• The nrf board I made has 2 servo(or RGB) outputs on 5/6.
• which leaves only p10 and 3 with pwm for speed control.
• Might just use a softservo and then keep the open pwm for the motor.
• For a updated board I can switch the nrf to from 8/9 to 8/4 I think and get D9 pwm free...
• I made a breakout board for the IC, will probabaly make the updated rx pinout match for easy assembly. and a full 4/5 ch rx board for brushless!
• The Remote pcb is in the mail but I have a working test remote.
• micro nrf board were made for a wireless rgb project which works great. but since they match the remote pinout I don't mind setting at least one up as an rx for now.

This project got my views in than my other one in 2 days vs 1 week. 

So fly, then walk.
