How i wish i can buy 1 from 3DR. I know that 3DR is a great company. But due to lack of Financial support I'm trying to find the cheap yet quality assured APM.

That's a loaded question!  My opinion is, if it works, then it's not a bad deal.  I won't say it's a good deal because you will probably NEVER get any support.  If you want the real deal, then you need to spend a little extra and purchase it from the factory, 3DR,  Although I have had some frustrations with my Pixhawk, the folks at 3DR have worked with me on resolving the issues which have really been my lack of knowledge on the product.  

Buy it from 3DR because YOU WILL need support.

Do you guys think this APM 2.6 clone is a good deal?

What are the other things i need to buy in order to operate this? compass?

Hello everyone,

I'm a complete beginner with zero experience in building planes and in the process of learning (via youtube/and this forum). My first project is going to be a skywalker X5, all parts are ordered and in the house.

My first question is with regard to setting up a Turnigy X9 transmitter & what to set/not to set under the FUNC options. There are a couple of dozens different items there and I have no clue what most of them were.

What I'm looking for is some basic numbers/parameters  to be set to start with.
Hope that makes sense. TIA for your help.

You need to set the ARSPD_PIN parameter = 65 for it to work

Great to know! I guess I forgot there's also I2C on the APM2.

The I2C digital airspeed sensors do work with APM2.

Comment by healthyfatboy on January 10, 2015 at 11:33am

If you don't currently have an airspeed sensor, you have to turn that off in the optional hardware menu. You're seeing junk data because it's reading whatever noise is on the analog pin and interpreting whatever it sees.

You can't calibrate something that's not there and dial it in. The board is just seeing a bunch of noise.

The APM2.6 can't use the digital airspeed sensor. Just get an analog one and follow the Wiki/Manual and it'll tell you how to get it connected and set up. Then go to the airspeed tuning section of the manual and get that going as well.

Thanks for the responses guys! So turn off Airspeed Sensor in MP where? and I do want to know my AS indicated and have only seen the analog sensor by 3DR and  pitot tube variety. Please link me the "digital" ASs unit option.

So then...what would cause my current AS to be so way off and jumping round-aboutly. Can I manipulate the params to dial it in or is there possibly an outside interference of sorts to consider?

Thanks again, Patrick

Coming from a gliding background, yes, the airspeed sensor is almost essential in a plane.

Secondly, APM 2.x and all it's clones uses the analogue sensor.

As does the old APM 1.x, yes, I still fly those !
