Eyes are not so good anymore so I am looking for bigger tablet iPad 9.7 - 10?
Can You recommend a good - compact adapter to fit it to RC?

This one from DJI store for example: https://store.dji.com/product/pg ... EAQYAiABEgKhLPD_BwE
You find them also on Amazon for more or less the same price.
There are also more expensive ones on the market like e.g. MavMount: http://www.mavmount.com/

Hi, thanks for reaching DJI Forum. We do appreciate bringing this query to us. Kindly refer to the photo below of the Tablet holder that is available to our DJI Online Store. Thank you.

My preference is for the MavMount.  I started with the one from PGYTech (offered by DJI store) and found it somewhat flex.  The contact points are only in the flexible section of the RC arms and the weight of the monitor allows it to wobble a bit.  With the newest iteration of the MavMount, he has designed a 'lip' or 'tab' that rests against the opened base of the Remote.  He's even managed to accommodate a cutout area for the control stick storage (in case you carry the extra sticks with you).  It's also far more adjustable and feels more secure.  There's a little more 'wrist room' between the screen and grip area....doesn't feel as cramped.  And it was real easy to fashion a neck strap for it.  
My experience, my opinion.

I have the knock-off on amazon (should be the highest rated one on amazon) and I love it.  Works great, the only issue is be careful with the nut that tightens it down - it’s plastic and doesn’t need to be cranked super tight to work.  Just snug.    But otherwise it definitely works great, even with my iPad Pro 10.5, which is hands down what I would recommend.  
Edit:  Here’s the one that has worked very well for me:  https://www.amazon.com/gp/product/B01N7RFDBA/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Yes, this one is identical to the PGYTECH sold by DJI. I also have yours both for tablet and a special one CrystalSky, which I broke today when trying to tighten the little screws that fix the vertical parts. For small tablets it is really good, CrystalSky is maybe a bit too heavy for the construction.
