Bit a fucking PITA to get 5 round burst
& bit different to 3 round burst (toggle by holding in semi)
5 round fire in auto (not semi) then go back n forth on selector 5 times:
auto-semi-auto-semi-auto-semi-auto-semi-auto-semi.... then back to auto for 5 round burst
learning these programmable qwirks can be a bigger challenge than playing peew peew
TBH - I thought an easier programme would be plug battery, hold trigger in semi
beep to enter programme mode, then pull trigger X times (quickly) to set X burst shot, holding last pull until it beeps to exit
This how some fancy bollox mosfets seem to work in programming various modes
& the ETU 2 only gives you normal, 3rnd or 5rnd burst so it could have been simplified with just its 1 option of 3 or 5 burst
*** NB but seems G&G went with two different sequence methods completely for 3 or 5 rnd burst ***
Hope you suss it
