BetaFPV Meteor 75 75pro battery adapter

BetaFPV Meteor 75/75pro have small bettery tray to use only BetaFPV 450/550 mah battery.
If you want to use other bigger battery, you may have to cut tray, it can caught your frame bend.
I design a battery adaper tray, It fit almost battery 1s 450/550 mah on the market.
You have to cut old tray like picture. try insert adapter from above. If it don't fit. you may have to trim frame a little bit by knife.
You can cut 2 bar like picture to insert motor if you solder motor directly to FC and want to change new Frame.
