"Hi Escobar .. People recommend what they find most useful, and for many people Telem1 is for telemetry and Telem2 is for companion computer .. The connection works just as well with USB, with a connection string that is identical for all companion…"

"HI Ashish .. You can "tune" ESCs via a BlHeli parameter set, but normally that would not be required to operate your quad .. Also flight controller parameter tuning should not be required for you to operate your quad. Go ahead and fly using all…"

"Hi Ashish ... it might be easier to ask questions by sending an email to info@KashmirWorldFoundation.org or Ronald@KashmirWorldFoundation.org

The "RC" port is the PPM RC input and the "SB" port is the PPM output. Zener diode is not required because…"

"Hi Ashish,

If you have Simon-K ESCs you will only be able to calibrate throttle. If you have BLHeli ESCs you will be able to change many parameters. For your application both options are fine.

For multicopters it is better to use ESCs that do not…"

"Hi Ashish,

I looks like you have a good wiring scheme.

If your power module did not come with your flight controller, check the pin order on the six pint connector as these are not always "standard." The existence of a red wire on an ESC does not…"

"Hi Dan. EMAX ESCs work just fine with Pixhawk flight controllers. It used to be that most people beginning with Pixhawk flight controllers did so with significant background with RC systems. Not so much anymore, so you may need some additional…"

"I took a quick look at the Flitetest forum. The posters attributed failures to hardware that were their failures to understand their hardware and firmware. For example the poster about Pixhawk 2.4.7 rail voltage did not have a clue as to what sets…"

"Let me repeat that the best advise I could give is stop reading posts about issues or watching YouTube gripes. EMAX ESCs are fully compatible with Pixhawk 2.4.7 and with all Pixhawk variants. If you like or have EMAX ESCs, use them. Some small ESCs…"

"If you want to keep the vehicle passive, install infrared illuminators on your aircraft and an infrared sensitive camera. I am assuming you are very much cost constrained, so try a little OV5647 camera with near IR illuminators available from…"

"Not sure you would go wrong with any of those choices. Best advise I could give is stop reading posts about issues or watching YouTube gripes. In nearly all cases the user is the problem, not the hardware. At KwF we exclusively use Favourite ESCs on…"

"Tinkering is good, but not with frames. The frames are more critical than they appear. They must be extremely light weight yet also very strong and rigid. You daughter can use her CAD and 3D printing skills to make fixtures for housing the avionics…"

"Hi Kayaken. Printing your frame is often a bad start, unless you have an SLS printer. Start with an inexpensive carbon or glass filled nylon frame such as an F450. There are some good kits available that include everything you might need. "

"You could test your theory by temporarily shutting off GPS during flight. With the EKF in Arduplane, it is unlikely you will notice much change in course if flying straight, so long as your compass is working reasonably well. Same is true with…"

"Hi Patrick,
We have experienced (too many) GPS glitches and compass failures, and none have caused straight and level fly away. Only times we have experienced straight and level fly away was with RC failure. Depending on the type of RC transceiver…"
