FS: APM 2.5+ w/ Enclosure - Blown 3.3V regulator

All,I have an APM2.5+ w/ enclosure (allows vertical adaptors) that i would like to sell. I found out recently that my 3.3V regulator was blown and I do not want to attempt to open it up and fix this. This was purchased directly from 3drobotics in Jan 2013. It has never flown higher than 1 foot above the ground.I plan on getting a APM 2.6 so wanted to help offset the cost by selling this APM.Asking $90.00.I am located in San Diego, CA.Please email me at chi.patel@gmail.com if…See More

"Crady,   Clearly what I thought was the correct way to install the props was backwards.  I thought the "R" was for counter-clockwise side.  I swapped the props and am getting thrust!!  Thank you SO much.  Time to…"

"Wow. I know you said the props are correct but it really sounds like your bird it trying to drive itself into the ground. "

Gerard Toonstra replied to Chirag Patel's discussion Cant Get Quad off the Ground
"Very strange. Instead of verifying the direction by position, see if it's going the right way considering its pitch. It basically works like a corkscrew. Each prop should spin in the direction of the highest edge, looking from the top. 1000kV…"

"Just ran a test: 50% throttle current draw (1505 PWM): 9;06V @ 37A 100% throttle current draw (1891 PWM): 8.3V @ 52A - 60A I keep saying FAILSAFE on my HUD. Chirag"

"Sorry, I missed that you were using 3S batteries and not 4S, but even then you should have more than adequate thrust. When connected to MP, can you see what kind current are you're drawing in the HUD? That should give you a clue as to whether…"
