PatrikR replied to eng.a.ramdan's discussion Stereo Camera Specs
"Hello,
 
Generally speaking the stereo effect is affected by the lens separation and the distance of the subject matter. If you plan to shoot stereographic landscapes the lenses need to be pretty far away from each other. In an UAV why not mount the…"

PatrikR commented on T.D. Gonzales's blog post First attempt at LiPo charging--disaster
"Get FMA Cellpro 4s or 10s charger. It's automatic and charges directly from Lipo's balance leads. No chance for anything like that. With a proper charger you can easily charge a 3000mAh battery with 3A or 1C. 
Don't go cheap on a charger and risk…"

Hello, Is there any chance to get separated ailerons so that flaperons/spoilerons could be programmed? Would be handy on several of my planes... Regards, Patrik

PatrikR replied to Assaf Weiss's discussion Programming flight modes on FUTABA 7C transmitter
"I have programmed my 12Z in such manner. 12Z is much easier to program but I would imagine that the best approach is to use dual rates to alter the first 3 states.
 
So try to program a 2 state switch as a dual rate for the 3 state switch.
 
Also…"

I just tried resetting the APM in CLI for approx. 100th of time and calibrating stick and modes. I changed the Flight Mode Channel to 7. I placed this code in my APM_config

PatrikR replied to Fred Briggs's discussion APM mode problem
"I have a similar problem. I set up flight modes to Manual, Stabilize, Auto and RTL. I use a Futaba 12Z radio. I have set up the switch ms exactly as described.

All seems fine in CLI but if I check the modes in groundstation the RTL is displayed as…"

I have 4 APM boards. Two work as should and have been flown several times.But the two new ones (could be old stock) don't allow any changes in CLI. CLI loads up fine but does not take any commands... If I type help, setup on the prompt and press…

PatrikR replied to Cenk Kucukkoylu's discussion Optimum TX/RX System For Video
"Hello,

I have the iftron kit, actually I have their divercity receiver and a few of their tx. It's a pretty package and works well but to get 500m you need patch antennas and tracking.

Also the higher the watts the hotter the TX gets. Some of the…"

PatrikR replied to PatrikR's discussion Rudder
"Ok!

Please verify. Under Stabilization Mode:

Aileron and Pitch are corrected. The servos counter act sudden movement.

Rudder is not? If I turn the APM on desk the rudder does not correct for sudden YAW? Is this a feature or a fault in my system?…"
