sending structs, need clarification on some things.

I checked my hardware after i was just gunna say yeah i can use the examples and noticed the connector i made was not holding tight to the NRF so i swaped out for a new one on my UNO and ran ping and worked fine. changing delay(10) will fail transmit/rec both even (11) or no delay. the 5,1000 was from trying to achieve less fail by telling it not to retransmit more than 5 times and wait 1 sec in between tries.

TX (uno)

Now sending 87...ok...Got response 87, round-trip delay: 24
Now sending 1112...ok...Got response 1112, round-trip delay: 22
Now sending 2135...ok...Got response 2135, round-trip delay: 21
Now sending 3158...ok...Got response 3158, round-trip delay: 21
Now sending 4179...ok...Got response 4179, round-trip delay: 23
Now sending 5202...ok...Got response 5202, round-trip delay: 23

RX(Mega2560)

Got payload 87...Sent response.
Got payload 1112...Sent response.
Got payload 2135...Sent response.
Got payload 3158...Sent response.
Got payload 4179...Sent response.
Got payload 5202...Sent response.

so i got excited and tried the old code.
but when i got back to the previous TX/RX code it is choppy send/rec and some fails. also if i chage it to even 11ms much less 1000 it is %100 fail agin.
Full code as it sits.
