I've to power APM with 6S batteries. I intend to use the PDB as power source. I must therefore step the voltage down to APM's required level, that is between 4.8V and 5.25V. This range must be kept under load to avoid a brown out.
In ultralight aircraft ballistic recovery systems are becoming more popular and some aircraft are sold with them as standard equipment. I've looked but haven't found any for our size of UAVs. Is anyone aware of a company that makes them? Perhaps thos
The alexmos looks really cool as it basically smooths out the yaw problem. So now I would love to get something like this going on my quad with gopro...

I am building a flamewheel 550 with dji 2212-920kv motors and 30A opto esc,and APM 2.6....I have the choice of 3 or 4 cell lipo....what will give me the longest flight-time of 5000mah 3c and 3800mah 4c (ca same weight)?
So I have been putting together different builds around an arducopter v3.0.1 using APM 2.5.2. So far I have had at least 20 great flights using different builds including a H-Quad frame and a RcTimer 450.
I attached the telem log.. Was doing a gimbal test this morning and did my usual check list had 12 sats everything checked nominal. Launched the hex and went to apprx 20 feet hit the loiter switch.. instantly it went into it then in another 2 seconds
the lights on the outputside sudenly stopped to light,and there is no power on the outputside. I can not arm it,and it dont connect to missionplaner...easy to fix,or do i have to go to the store and buy a new one? ;-)
Is it anyone who use happymodel gps-unit with four leads (yellow,green,red and blue) and can tell wich contact on the arducopter(on the gps-contact on the side) the different colours are ment to go to.?
Hi all, dji f450 frame with stock motors and escs. been trying to tune this for what seems an age. Stabilize is perfect but when in alt hold or loiter the quad wants to rise and the motors pulse. it is a heavy quad but the altitude is not constant, u
