I have ordered some parts and while I'm waiting on delivery I have been planning out the main frame.

Using the TBS Discovery as a base, I'm going to design my own frame to fit with the components that I have / can afford.

I began laying things out and have already come across my first hurdle:

In the center is my APM, in front (with corner mounting holes) is my Brussless Gimbal Controller. The three holes in the nose will house rubber vibration grommets attaching a plate which will i'll mount the gimbal too.

The red square represents the aprox. size of the Q-Brain quad ESC that I have. I can already see that having this ESC will be a pain as keeping it far away from the other elecronics is nearly imposible.

I'm thinking at the moment, because I certainly don't want it beneath/above the APM and I'm mounting the FPV/Telemetry gear towards the rear, that mounting the ESC beneath the BGC and possably outside the frame to give it some airflow might be the best bet.
