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! ;)
