I'm not 101% certain but the ASTER might not work with the HC05
Well not out of the box...
The HC05 DSG sector has no COL cams on it
(well unless G&G has revised it)
The ASTER optically reads the COL cam on the sector gear for timings
Yeah.... One problem - the 5mm axle G&G DSG doesn't have any cams to read
So it ain't gonna do jack shit as far as I can tell
A similar problem with the ASTER and the TSG conversion thingy
is that affixing the top half of TSG to a reg lower half sector
means you only have ONE COL cam for the TRI-SECTOR-GEAR
(or affixing a DSG upper to a 12:1 lower sector to create a 6.25:1 ratio - only ONE COL CAM)
So the TSG or 12:1 DSG in an ASTER means it will fire 2 or three times (one full revolution)
then the ASTER's optical sensors set at an angle finally detect the single cam
NOW you could build your own "cams" for the ASTER to detect but will involve a bit of testing & shaving
see this video to understand it a bit...
He has the ASTER and this is what he had to do to get the TSG to operate in semi correctly
and in theory similar crap would apply to the HC05 DSG with no cams to begin with
Another thing to watch for is that many of these fancy mosfets are quite large
and even on 8mm bushings they come close to the outer edge of the sector's 8mm bushing
(they clear it, but on some models it is a little closer than others)
The HC05 has 9mm so called ceramics which are quite chunky
Yes you can replace these with 5KU 9mm bushings & 9mm SHS bearings
However - the G&G cam-less DSG (and the default Spur/Step gear) has 5MM Axles not 3mm
ergh so you can't just use a lower profile 9mm bearing or a 9mm bushing without enlarging the 3mm to 5mm
Now you "might" just about be OK with fitting the ASTER with the ultra chunky 9mm G&G ceramic with 5mm axles
but they are a bit chunky from what I remember
and here is pic of ASTER - with the red led beaming downwards trying to pick up the COL cam on sector
(which doesn't exist on G&G DSG unless you make them up from JB Weld etc...)
Really - what you should have bought was the Perun v2 Optical...
View attachment 68534
as it is much smaller - so totally misses the 9mm chunky ceramics
plus the sensors pick up the sectors teeth for timings - not COL cam
so would work on the cam-less G&G DSG & not be tight on chunky ceramics
The gear set in the HC05 is a reg 18:1 ratio
with a 10 tooth bevel I'm pretty sure of
but the spur/step gear was a weird 5mm axle and didn't run smoothly for me
so got a SHS 16:1 gear set, used the bevel & spur,
some 9mm bearings (couldn't get 9mm bushings quickly)
then moved some stuff around - put 9mm ceramics with 3mm axle for 16:1 spur
then SHS 9mm 3mm bearings on the bevel ( I think )
so had a spare couple of the G&G 9mm ceramics with 5mm centre for the weird DSG axle
I've got 9mm bushings now and one day may revisit my HC05 box
and fit the Perun Optical in it nad finally get it firing 101% on semi etc... at long last
But the thing is I would not put it back into the FireHawk in the end
as such a short 128mm barrel means you lose fps on the DSG
so would probably look to swap boxes from say a G&G FFR A2 with a 205-ish barrel
(FFR A2 is/was an ETU that crapped out so is now old school trigger 13:1)
and this reg G&G box with 13:1's for the FireHawk instead - basically straight swap of boxes
but gain a bit of fps (hopefully) in the longer FFR A2
Similar thing to you fitting a longer barrel where you should see some gain/creep
But for me I'd drop the box into a slightly longer CQB M4 and keep the titchy FH look
(but to each their own as they say, yet it is a lot of fucking around regardless)
The motor's in the FireHawk's is or was the Blue "Powerful Motor" ferrite but about 24,000rpm
(sorta weaker version of Orange Ifrit) - but pulls the DSG out of box
and fitted or WAS fitted to other FH's, CM18's and perhaps the 30th spec editions
but not always fitted to all guns - even the FFR A2 has the lame 27tpa/18k grey in there - shocked
Anyway the Blue motor isn't bad for a stock motor
and can get say 18rps on 13:1 with the G&G Bluey motor (done right with a few teeth SS'd) on 7.4v
maybe 16~17rps if needed a slightly bigger spring in a 128mm barrel
but still have option for snappy 7.4v and/or 25~26rps on 11.1v
(getting near the TopTech FireHawk performance)
To be absolutely honest - the HC05 is still a pile of shit imho
if G&G haven't sorted it out and got it to fire semi
or fitted the Perun Optical then they are bigger idiots than ever
you'd be better off getting a NORMAL FireHawk
steel 8mm bushings, metal rack SHS piston, SHS DSG with a bevel+spur from 16:1 SHS
(you should have the same motor anyway)
at least you will have semi unlike the HC05 out of box
well tbh I'd probably do the std FH as 13:1 than DSG
and say a 200~250mm M4 like the FFR A2 or short Raider sleeper gun as DSG
yeah the HC05 could be re-done with perhaps the Perun V2 Optical as best option
But it is still a fucking wank if G&G are knocking the exact same shit CQB guns out
Oh and DON'T use a High Speed motor like the BD-M160
stick with say a 25k to 30k SHS High Torque motor tops
maybe 18tpa to say 22tpa if you are trying hit over 350fps on titchy barrel gun
so need a slightly heavier spring
yeah the HC05 is still a pita & one that people should read up on before buying
(hence this post was originally more of a warning than a review)
