Here I am trying to figure out which CAP is missing (thinking capacitor). Ooops...finally saw the tree for the forest. The cover on the gyro is missing. I'll have to check mine. A little hot glue should hurt. I'm not sure what to say about a missing cover though.

Today when I was going to fly my quad (also from Minsoo Kim) the pitch gyro is not responding. I've got 4,7v, but no response to
Any ideas?

Fixed it, bad solder joints.
Hmm, don't know if I'm even going to trust it carrying my GoProHD cam.

Is it possible, that the KK Board don't like cold wind or something?
I flew 10minutes and after i changed my LiPo i was not able to activate the board (i fly a tricopter so i have to activate/unlock the board).
When i was back in the house, i was able to unlock it. Then i went out to fly another 10min and then locked the board. I tried to unlock it again and the LED stayed dark.

Back in my room it is working fine.

I find that after a minute of flying if I havent let my quad sit in the ambient air before flying I have to land disarm it and then rearm it again to get it to stop drifitng in the air. It might be a similar thing for you. Try letting the quad sit on the ground for a few minutes before lifting off.

This is very interesting.
The EPP aircraft landing skid is the role of the wing.
High speed is very stable in a rising or falling.

That looks like fun. Will you be offering a 'kit' version? I've already got a KK board to use. I'd just be looking at the frame parts and possibly motors and escs.

picked both quad & hex blue v 1.5 boards from minsoo. after initial setup on the quad with a jr 9303 spectrum ar 7000 & these escs http://www.hobbyking.com/hobbyking/s...idProduct=6458 .( are these escs compatible?) i can get the board to arm but speedos just rapidly beep. tried lowering subtrim & travel adj on throttle but no joy. the manual states to calibrate the escs but doesn,t say wheather it should be done manually or through the controller. i tried both ways & still get rapid beeping on board arming. any ideas? the fact the board arms seems to confirm good channel assignments. it,s actually the manual thats kinda vague on the esc throttle calibration. step 4 says to calibrate ecs throttle & bat type. next is to lower gain pot, power up with throttle full then idle which is effectively reprogramming the throttle calibration through the board this time. when my ecs are calibrated direct through th rx they see both full & idle but when done through the board the second time they don,t see idle for some reason..can the hex board be used with 2.4 spectrum rxs (thought i read somewhere it couldn,t ).any input appreciated...thanks..rob m

Rob,

I'm not familiar with your ESCs, but if the throttle can be manually calibrated I think they should work. I have the KK hex board and use a Spektrum AR500 Rx and have had no issues...short of changing flight modes and I fixed that by increasing my control EPAs. I'm using RCTimer (Hobbywing) ESCs with no issue. By my recall I lowered the YAW gain to minimum, powered up my Tx and put the throttle to full. I then applied power to the KK board, waited and listened for the tones signaling my ESCs were in throttle cal mode. I then dropped my throttle to cutoff and then removed power to the KK board. Of course, do this with the throttle trim all the way down and props removed. When I power the KK back up the ESCs do their normal tones and wait for me to arm the controller then off flying.

I have the same problem with motors
When is cold outside 5 centigrate my turnigy plus 12A are
beeping only but in room temperature motors start normaly.
I have found solution Try during beeping manually turn propeler of every motor as fast as possible it usually helps me.
I think that cold motor bearings dont move freely /they are cold/
and motor is not able to turn easy and then motor can not produce impulses
for ESC during start procedure.

Dear Sir
we are going to release the fun fly set without the controller board.
I think that it is the best combination.

Thanks

The hot glue is very useful.
