Another day lost to a dead glow plug ignitor... I met Mike Pearson to fly his Eco 8 electric and my 10cc prototype, but was unable to get the large prototype engine started. I believe the problem is that my glow plug driver needed to be charged.

So, in a fit of frustration I build a new field box that incorporates a "Power Panel" with step down circuitry to drive the glowplug from my 20 AH gel cell. It required a new case to fit properly, but on the plus side the fuel bottle is now stored upright and the transmitter is better protected.

I also tried to characterize the errors in the accelerometer sampling code. There is a plot of data readings for ten minutes of the IMU (image) on a stationary workbench.
