C 4 U

So moved the common parts of Vicacopter's PIC code to C for Vicaglider, using SDCC as the compiler. The complete Vicacopter code is 2940 bytes in assembly. The common sections alone went to 7600 bytes in C. Inefficient translation of C has always destroyed PICs.

It's probably too slow in C, so that ends any more Vicaglider until test hardware exists. Vicaglider is history until we recover the cost from...

Vicacopter II's airframe arrived after 10 days, complete with smashed canopy. The Align 430XL motor is probably too small to do the job, so we'll be studying governor mode on the old Phoenix 45.

The Stock 450 motor

The stock 450 motor is plenty powerful.
I did some work on an autopilot on the 450, and I gave it up for the 600 because the tail rotor belts kept failing. Plenty of power to lift 18oz, but
the extra load on the tail rotor kept wearing out the belts. (450 SE)

Looking forward to replacing tail belts.

Outrunner motor (like your 430XL) are always smaller and lighter then inrunner motor for the same output power. These days, outrunner motor are far more popular then inrunner in Heli application. They give more power but are generally less efficient.

430XL is decent motor, you will see.
