First we can use it against another sentry or/and with a flying sentry
Second how we can recharge that sentry ,if The sentry is flying we just do like we do with The classic sentry just punch it or The flying sentry just explote when is with out ammo
Third what happen if we die but The sentry not ,the sentry stay there where we die and still killing The enemy or it just go to the respawn
Fourth with the wrangler we can use it to point and kill The enemy
Fight we can sapper that flying sentry
Whell that are all my questions thanks if you read it and if you answer my questions
Good idea man :)
