Inside the Hummingbird–Now the tuning & issue begins!
I will post all internals and how the bird work and whats need tuning or improvements in this Topic. This BP is going to be a hit, vary well made over the cricket.
Got her today so I will cover several area as I go along tuning and adjusting:
1. the gauge isn’t aligned properly in my book. So if you have a standard cricket gauge socket it will fit the HB, but 1st the AT must be vented
under the trigger guard is where the standard fill hole and use the same fill probe as the cricket, as you can see on the photo near the fill hole is
the bleed screw—-> its a larger heavy duty screw compare to the cricket. After all the air is vented the AT can be unscrew—this AT wall thickness is thick and heavy–so vary unlikely you wont dent the AT in normal use–even dropping the HB. the oring that seals the AT is 3mm X 30mm. the fill
check valve is the same size as the cricket, had to increase the fill rate to my liking vary easy to do.
2. Now I’m having issue with the bolt blowing back when shooting pellets, when it does a lot of air will blow on your cheek and scare the shit out of me the 1st time it happen also the speed will drop about 8 to 12 fps. now it blow back about 2 to 3 time a mag full that not good—have to find this problem. Has to be the locking ball of some type—its like a free floating bolt after its cock if nothing locking it in place it will blow back! If anybody has this problem let me know!!!! 😥

Darryl, Don’t get hung up on what I said about the trigger linkage, It is not Earnest’s job to “fix” this sub standard component, although his vids are great they would only be half as long if he didnt say “all-right”? every second word… he’s senile and old and forgets to dress himself most days.. 
The parts will more than likely last longer than you keep the gun for, my point was that its supposed to be a quality gun from a quality gun maker but they cut costs on every part they can yet the buy price doesnt change..
If I were making a quality production PCP the last thing Id be doing is scrimping on the little things like plastic linkage ball joints when there are high quality stainless steel or alloy ones available for not much more. It says a lot for you name and intent in my eyes.
The linkage components dont have the high impact stresses and grit involved that R/C cars have so the plastic will no doubt operate fine without too much play for years but it certainly not what Id be expecting to pay for in a high end PCP.
Now Ernest! You know I don’t do well on multiple-choice questions! :rofl: But your perspective on the trigger linkage is reassuring to me since this is the most expensive airgun I’ve ever purchased new. Also, you did say the internals seemed more robust than in the Cricket. That may be due to the attempt at a semi-auto. Maybe we’ll benefit from that in the long term.
thanks to you and to Wingman for his views as well. Things that make you go “hhmmmm….”

To Ernest, to Wingman’s point abut the plastic trigger linkage(s), got anything up your sleeve for that or do you think these parts will be durable over the long haul, or at least easy enough to replace (or both)? Nice tutorial on how to adjust the regulator, btw.
darryl
You know Wingman is still a little boy he says a lot BS without thinking, let me tell you why– I too was in to electric RC truck and bugges that cost Over 1K just for 1 RC, racing 35 to 50+ mph crashing over other RC or stationary object, a fully loaded RC weight over 10lbs crashing at 50mph even tumbling over 10 times or so till complete stop/–the most parts I have in the tool Ben are steering rods linkage, in almost every crash I repalce one or two. Now let’s talk about AG where to same type of linkage are use? At most the trigger blade will only experience no more then 2 lbs force with the softest skin touching the trigger blade and you know we treat the trigger so softly to get the best accuracy. Like how many shots can you get off in one day of shooting —-500 rounds at that, now how many times the linkage travel up and down in one race —- 30K at least.
Now you tell me who make more sense a young boy that is learning or a 58 year old seal member that killed so many men—just joking
Don’t get me wrong I respect “WingMan” only when he has something in his hand to review. just like me all hands in my videos.
Ville, I understand what you’re saying. I must admit that I was disappointed by the fail-news too. The saving grace for me is that the HB will likely be my only bull-pup, and only one of two PCPs, only one of three airguns, as I’ve reduced by what I don’t use.

It sure is easy and the fact the AT doesn´t need to be bled for the job is a very good thing.
I have nothing against the Colibri itself. I just low the idea they´re selling it at a same price they had set for a semi-auto version. I don´t need a semi-auto since AG hunting is a no-no over here. I ordered one as a pure novelty item / cool thing. Now there´s nothing overly cool into it since it´s just a one more Bullpup in a growing heap of BP´s so i cancelled the order. It just pisses me off that it took KalibrGun such long time to admit they didn´t get it to work as semi-auto BUT it´s better they didn´t let out a semi-working semi-auto. I just wish i didn´t have to wait that info for half a year ..
And that they would´ve lowered the price.
This Video is to adjust the reg pressure: adjustment is just loosening a set screw and turning a hex nut. mark you original setting before adjusting. set mine at up to 915 from 905FPS with 18.1g the 15.9 shooting at 960fps this time I adjusted the HST after increasing the reg pressure. simplest reg to adjust, no need to bleed pressure!

Dave, I hope there’s at east a warranty! :rofl: Seriously, we need to know the dealers have a commitment to customer service (even if it hurts). But i’m not going to question my purchase decision at this point. in for penny; in for a pound.
darryl
Darryl I feel the same. Wondering if I should wait until KG gets it right.
Dave
just like the first model year of some cars with some things not quite right. I’ve asked to have mine checked for proper operation before being sent; Blow-by, and power setting ( I want 30 fpe with 18 grain pellets), and a general once-over to be sure. I’d rather not have to deal with issues right out of the box.
darryl
It sure seems a lot of work to be done to to fix and maintain a Gun that cost that much :confusedn: :confusedn:
It seems Kaliber should send his guns to Ernest before going into production for a final inspection. Save everyone a step.
There’s no adjustment for the 2nd stage break, So what I have done is remove the burrs on the edge of the shear then polish. ended up with a 10.5 OZ trigger prior was 1lb 13oz. just to tell you owners that it can be done in turning it to a match trigger.

Its All good, when two knowledgeable AG has disagreement we AG gets great INFO and learn more then we know.
1 st Leak, kinda disappointment but anyway got to go on (like the 1st batch of crickets that had leak issue that continue till today). that’s the reason I went through and disassemble the whole reg while I was in there, then adjusted the reg pressure. here’s the leak Video
