Titmouse 3 inch fpv frame quadcopter

Last crawled date: 1 year, 10 months ago

I present the second frame for the fpv quadrocopter of my design - Titmouse (fpv quadcopter frame).
The frame contains several configurations: for the connector xt30, mt30 (harder to open), for 3D printing (thicker arms).

The final weight with all components turned out to be 120 grams. The frame itself is 20 grams. I think for an assembly with a full-fledged gps + compass and a digital video system, this is a good result. With 650-800mah battery less then 249grams.

Features - which may raise questions.
I made the frame as narrow as possible in pursuit of weight, compactness and the location of the center of gravity as close as possible to the planes of the propellers.
All frame made of only one thickness carbon piece 2mm. For 3inch propellers this is enough for rigidity, it can be seen from the blackbox logs.

I configured the quadcopter on inav with the following pids using pid_analyser:

set mc_p_pitch = 30
set mc_i_pitch = 45
set mc_d_pitch = 14
set mc_p_roll = 26
set mc_i_roll = 40
set mc_d_roll = 12
set mc_p_yaw = 35
set mc_i_yaw = 40


I admit that the setting is not ideal, but on light batteries (up to 1000mah) it flies smoothly without shaking and oscillating.
