MAK RC Heli Servo Centering Tool

There are many servo testers and even some servo centering tools available on the market. I didn’t find though the one I wanted to have, with selectable 1500/1520µs PWM outputs and also with 760/960µs outputs for helicopter fast tail servos.

The MAK RC Heli Servo Centering Tool may be especially interesting for RC helicopter modellers, due to its fast tail servo PWM output. Of course Flybarless controller unit can be always used to center servos, but I like to mount FBL unit at very end, without bothering about it during the build process.

There are many popular lost RC model finders available on the market. They are usually simple and inexpensive devices, activated by signal loss or inactivity on RC channel which they are connected to, after some pre-defined time.

They work, but they are rather cumbersome in use, as they often activate themselves in unwanted conditions, often on the ground, before a flight or after landing. They are also dependent on model’s power source and having small buzzers.

Thus I decided to develop my own lost model finder – MAK RC Model Finder (MRCMF) – under following assumptions:
