*VIDEO STRIPES problem solved, it was caused by regulator interference to camera (not motor to Vtx cables at all... but change all the video cabling too, who knows )
I added shielded and shorter camera cable with ferrite ring, and cover the part of pod with aluminium sheet, cut out the microphone - problem disapear (I realy hope, not tested in the air, but on the ground it is ok now)

*before I changed the camera cable I made a flight aprox. 700-800meter high today, I think it works a pretty now and I am finally satisfied

Plannes to the Future:
Activate the OSD
Head Tracking
Activate microphone
try again calibrate RSSI
Change the battery to 3000mAh (now I have to fly with 40grams ballast in the nose because UHF is to much on the back of the fuselage, next time I will place it in diferent way
Oracle Diversity for whip and patch together for the begin...

Hello Sprstemvnose,

I start to build the FPV with a Beta 1400 last year but still many problems with the weight of model.
Im very supprise that you fly with a lot of material in Beta and also in video its looks that the take off are perfect.
With my material I have a weight around 900 grs and the take off is very bad. The plane goes down almost touches the ground.
You live in cz me too, I prefere write in english, Im not czech.
Can i write my configuration and can you hlep me ?
