Thomas Butler commented on Nicolai Valenti's blog post Gas Drone 3 Hour flight time
"Looks a bit tippy!  Can it do more than hover? Perhaps it needs a Pixhawk! Are you familiar with UTC (specifically UTAP division) in Rockford, Illinois. They are working on hybrid generators for primary aircraft propulsion."

"@Kendall, Thanks for the info. For beyond the real PWM outputs, there is an SBus output port on the TBT-AV1. With the Atmel E70/V71 300Mhz (ARM M7 core) MCU, there is plenty of processing power to support it."

"@Kendall, The E70/V71 does have an ethernet interface in the MCU, but the ethernet pins are shared with PWM pins and are not usable at this time. A change to the 144pin version of the MCU would allow both. Specifically what…"

"2 years of R&D is pretty good time you had and I appreciate your efforts but now a days is the trend of suspended IMU which is missing in it. With suspended IMU, you really do not need to care about providing additional vibration damping pad."

Thomas Butler commented on Chris Anderson's blog post NXP is giving away 100 PX4-based development copters for its firefighting competition
"Uh! Not quite. READ THE very tiny FINE PRINT! What you get is a $300 discount coupon. It costs $350 plus sales taxes on $650 price plus shipping (+-$20). Read the fine print on their web site. The real cost is about $400. Oh, and there is no…"

"Interesting in that the FC used is a microcontroller manufacturer's reference design (not really acceptable as a product[it's a reference design for how to use the MCU]) for it's variant of an ARM M4 core microcontroller, AND it is a…"
