Cool - no wobbly nozzle then ???
coz the SHS ones I have - from Gunfire & decent Chinese sellers were a bit loose
(snug in other tappets like SHS ones, but was loose in Cyma clear & recent blue tappets)
had some snide lighter red/pink nozzles that were shorter & fit poorly in every tappet
mind you the nozzles i got are a few years old I guess, even the SHS ones
so if Pete's nozzles fit snuggly I'd be interested in grabbing a few myself
POM nozzles that are too tight fit can distort if wedged into a tappet & lose good seal at o-ring
it is the classic pita compatible crap - often stuff works alright but other times they don't go to plan
(like the larger eyelet on Cyma switches, v3 spring guide in v2's, ultra loose as fuck cylinder head
odd safety arm screw outside box, different tappet plate, possible qwirky nozzle, reinforced box for 13:1's
piston head is alright once you change o-ring though)
cheers for heads up - might drop Pete a line re nozzles
21.4mm ish, it is in Luke's recent video
but knew that anyway - it is around 21.4~21.45
(common M4 nozzle, some use nozzles a little shorter like ICS & some others)
in some boxes/builds it can a whisker too long
hence measure nozzle and other stuff to compare it all
but yeah Cyma's are usual 21.4mm
