So it happened again, and it will continue to happen until people realize this technology is far from mature enough to be used for such tasks.

Aside from endangering peoples lives, the public opinion created from such incidents will be very damaging and contribute to overly restrictive UAV laws in…

Hei

Fant deg her på diydrones og tipper du har arducopter? Jeg prøver å kartlegge antall piloter i Norge for
å skrive en artikkel om dette.

Også skal vi i løpet av året organisere en arducopter / uav dag og du er kanskje interessert?

Heisann. Har vel strengt tatt ikke et arducopter da jeg liker å bygge mest mulig selv, men flyr quad mm. ja. :) Noe samling høres moro ut.

Hi john, i am able to get PPM output from a PIN of Thomas Scherrer 12 channel receiver. is the PPM sum signal compatible with the ATmega2560 PPM decoder or i have to decode it through a interface. actually i am more of an aircraft engineer and less of a electronic engineer. the signal is coming from a Futaba 7C Tx onto a 12 channel thomas Sherrer Rx on 12 channel pin. can i give it directly to PIN 1 of APM after shortening PIN 2 &3 or i have to use an interface using PPMencoder. please help. i am currently using APM2.23. thanx, ravi

Hi john, i tried giving PPM to channel 1 PIN of APM and shortend PIN 2 & 3. did not work. I am not getting PWM out to servoes. Thomas Scherrer Rx takes PPM pulse from Futaba 7C Radio. It has a UHF RF Module which has been connected to the PPM out of Futaba 7C, this drives a 12 channel Rx also designed by Thomas Scharrer. I think the PPM pulse form futaba 7C should pass on as it is to the Thomas Scharre Rx which has a PIN for direct PPM out? what should i do next.

Hey John!

Do you have any updates on Crawler1? What do you think of the Redcat Rockslide 1/8th? How does it hold up to your use/abuse? One of the things about the RS is that the only place making after-market parts for it seems to be RedCat itself, not many 3rd party manufacturers. Has that been a problem?

Thanks for any updates you can provide! ;)
