I’ve had the same problem with loose battery terminals on other radios. You can use a small screwdriver or something to GENTLY bend the spring tab outward to put more pressure on the battery contact points. If this doesn’t work you just have to be a bit careful haha!
Well, I've got a comment that I've used wrong battary. The 21700 should be used - as I understood it should fit well.... Or I should go to doctor to treat flu))
I didn't know you were into FPV! I'm down to deciding between the radiomaster pocket, jumper t14, and t20. Jumpers are a great price but IDK. They have Banggood vibes
