Renato Aranghelovici commented on Jimmy Oliver's blog post Bebop Drone Accessories
"Let me finish tests, will open a new thread, with all the data.
Avoiding to raise a wave of hope without hard facts :)"

"Still 33g arent negligible... even the 14 grams of lateral bumpers are noticeable, one minute less flight... plus lateral drag (wind influence) added, plus lowering CoG, with potential balance change.
Why did you feel the need for taller landing ?
I…"

"Posting as a Bebop owner.

The landing gear is too massive, adds to much to the weight, imo.Never felt the need for taller feet, just replaced the hard rubber bumpers with taller and much soft silicone bumpers (gimbal vibration dampers), search on…"

Renato Aranghelovici commented on Sandro Benigno's blog post Why FRSky CPPM signal is so disappointing. [UPDATED]
"No experience with pixhawk, but according to description:

"the port labeled "SB" can read RSSI or output S.Bus to servos""

"From ch2 signal pin.
"...still get RSSI..." what you mean by still ? How you get RSSI before upgrade ?"

"My guess is that you are using D8R as a normal receiver, and not in CPPM mode.
The issues described in this thread are for CPPM mode only, not apply for normal receiver usage."

"Probably in LOS, if you are talking about 38k, after 1km the speed drop significantly and the dreaded buffering start at 4800bps, read more here:

"Xbee based RC attempts were made years ago, the creator of OpenLRS was the last who convinced himself they are not a solution due to latency and buffering these devices does.
Telemetry yes, RC no, or anything where you need better than 0.1 second…"

Renato Aranghelovici commented on Eric's blog post Lightweight Snap-Foldable Y6
"A very similar setup, i.e. foldable, full carbon, X4/6/8 multiconfiguration, etc, exists on the market for more than one year as Mini650. This is mine:






















985 grams without battery, what you see.
Cool, but big loss of efficiency,…"

Renato Aranghelovici commented on Joshua Ott's blog post T-Motor is looking for our help to develop UAV specific motors
"Double the amount, you forgot batteries. Such setup will not fly with a single 5000s/4/6s. Actual Ferdinand setup (97 minutes) contains batteries costing same as the rest of hardware (less electronics).
Anyway, is an futile exercise, simulation…"

"I think such motors ARE already in the market... the electric bike motors, have pole count in the same ballpark, and direct drive a 26" wheel."

"Yes, was my special design criteria for Frsky when XP firmware was issued.
The reasons to move CPPM and related signals to lower channels pins, instead ch8 as before, are obvious:
- people who need CPPM decodes at least the first four channels in…"

Renato Aranghelovici commented on Sandro Benigno's blog post Why FRSky CPPM signal is so disappointing. [UPDATED]
"D8R-II+ does not output CPPM natively, so you shouldn't be worried because you can't use it in this mode as is.
However, the 27ms firmware can be applied on your receiver."

"When it comes to RC low pass filters, there is no such thing as optimum.
Use any resistor in 10-47k range and capacitor between 1-10uF, the product of their values must be bigger than 0.02, the bigger the better, unless your OSD has a RSSI input…"

"ANY D8 receiver, since the first days in 2010 can be flashed with any Frsky firmware, nothing changed at hardware level, only pin ports added or removed."
