trimmer pots

I swapped out the 20k trimmer pots from my 401k's and put in these 10k's from mouser:

http://mouser.com/Search/ProductDeta...2-3314J-1-103E

The tri was much easier to trim and I was able to get rid of all the wobbles. I think they are still reversed (all the way clockwise is off) but they work great.

However I just had a look at that page on your programmer on ebay and it did not mention supporting Atmega328P . Might be cheaper to buy a supported chip than another more hard core programmer...

I don't think it is a programmer (hardware) issue. eXtreme Burner is the AVI burner program that does not have the data base for the 328P. Their web site has a Q&A and there have been questions about chips not in the database and they suggested to create a data base for that chip.
Now I am trying to find all the info, this is what the chips.xml database looks like for the ATmega88

Hello all,

After trying the kapteinkuk quad on 420RCpilot PCB with separte gyro board, I received yesterday JacubJ all in one PCB. So I did solder it and it seems to work but the LED doesn't stay on as with previous pcb. It blinks slowly and stays like that.

Doesn't anyone knows what does this mean ?

By the way, I was testing it in my living room and tomorrow, I will give it a real maiden flight. I will give you feedback as it is the first time that I will fly a quad in X mode

Also RC-timer ESC´s are same as Hobbywing (OEM)....

TowerHobbies are not only slow, but also way overpriced. 2 years ago I bought a 15 dollar part from them, and they keep sending me catalouges 4 times a year - I suspect that is pretty expensive......and that the cost is forwarded to custumers by overpricing items. Like 29.99 dollars for an 800 Mah 3S 20C....LOL
thanks for the info, will look for some of the others

I'm not aware of slow flashing with Kaptein's software. After the RX receives a low signal on the throttle for some seconds, it will turn on the LED solidly. Are you sure the LED is not loosen?

10 or 20k pot size should not make any difference

You can reverse the direction of the pots, see the first post.

Is your fuse settings correct? CKDIV8 unchecked?

Well, The ATMega is the same as in my former setup. I just moved it from a board to the other one ...

LED was a 3mm red one on the 420RCPilot PCB and a 5mm yellow one on JacubJ PCB. The only difference is that I used 47 uF tantalum and not the 2.2 uF ones. But I don't think that it could change anything (btw I use 4.3 firmware).

The question is : if it flies fine tomorrow, is it a big deal ?

There is no slow continous blinking in the software. What is the frequency? It might be resetting itself.

A note about the ESC's: increase the timing. With the recomended Turnigy Plush series and the renamed similar ESC's set the timing to medium.

If you use the low timing, the motor might stop and make that screaming sound. This can espesially happen during violent manouvers. It loses the sync with the motor.

Creating a xml file for it with correct memory size and chip signature may get it working. If not avrdude software does support 328P and lists an ATtiny programmer so it may work also. I have a 328 xml file for my atmel programmer but way more chip info in it than what was listed but it might help.

ATmega328P
FLASH=32768
