I have a 250 quad and a plane with v tail under production. Both. I would prefer any under 7k. And what do you think of avionic rcb6i as tx/rx.?
Thanks  in advance. 

I  prefer one with options to mix such as elevons etc.     

Sir you can go for flysky t6 available on kkrobotic.info

I somewhat recommend that radio although thats cheap , portable ,got a lcd  and easy to use but reliability is the thing i got trailed. Though i did minor mods to it but thats not the root of problems. What i think you should contact rcb to ask if they have solved the(asus modem only) wifi interference issue. If they say yes then its a good choice. Otherwise stay away from wi-fi networks

edit - talkin bout rcb6i

Thank you. What do you think of avionic th-9x ?  Is it good to go for long term ??

Its a fly sky th9x.
Excellent radio with heavy potentials.
1. Add frsky module
2. Flash opentx/er9x
3. Get telemetry
4. Backlit lcd
5. All in all best choice

thanks @voice_of_deaf.
