Sirs,
I've noticed something with my RD...medyo po maganit ang trigger nya...one time the trigger locked and I didn't know what to do. When I brought it to a gunsmith, wala po namang problema. It appears that the lever (of the gearbox when it's pull out of the gun) gets in the way so you just have to move it such that the trigger can't be locked.
I also noticed that medyo mas mabigat yung trigger nya compared to the TR version that I got recently.
Anyone of you had the same experience? Would I have to lubricate any areas for this problem?
I still have not tinkered much with my P90 but I plan as we move forward.

The great thing about the P90 version 6 gearbox is the way that you can access the trigger areas without having to OPEN UP the gearbox itself. Just remove the screws that are holding the plastic trigger assembly to the Gearbox and you can take a peek inside as to what's causing your trigger problem. If there's noting obviously broken- then a little lube might go a long long way... 
We can deal with opening your gbox at a later date when I can take some pics and show you a step-by-step.

Sir Stan,
Please also take pictures of the screws that you are referring to that hold the plastic trigger assembly to the gearbox. Are these the two screws from the back that hold the gearbox in place?
These are the screws which I have take off. Then I pulled out the gearbox from the rear...let me know sir if I am doing something wrong.
Thanks,
Sarge

Will try to take pics soon sir... just have to borrow a digicam coz my phonecam sux.
In the meantime, it's realy not that hard. Once you remove the gearobox(you did it right btw). You can see the THREE screws that are holding the trigger assy in place. These screws are located within the plastic trigger assembly- there's no missing them. Just remove them and you can take a peek into the trigger assy. You'll need a Size Ten TOrx head driver though.

I'm afraid that our WELL P90 is rather limited in upgrade options sir. I also had one of those before and I tried several different tricks to increase it's power but the gains were rather small an not quite proportional to the effort exhuasted(sa madaling salita- mahirap at hindi- sulit).
I suggest you enjoy your WELL P90 for what it is.. a fun and inexpensive plinking toy.

Sir Stan,
I just read your mail about using a type 1 and/or type to for a certain tight barrel length for a P90. I really am having a tough time understanding all of this. What is the best mix for barrel lengths...at least for the TM P90.
I also asked someone once about using a tight barrell...for P90, he was suggesting that if I'd still want to make use of the silencer function, I should choose a barrel whose length is somewhere between that of the MP5 and an M4 (not sure how long these are....and his recommended length...and that a sealed barrel should be used.
I'm not a gearbox techy but is there any computation to be done to compute for the best cylinder type for a certain barrel type and length? Like, I can only guess/picture that the amount of air pushed to move the bb from the hopup up assy to the barrel exit should be just right to shoot the bb efficiently...
Pano po ba i-determine yung process?
Thanks
Sarge

sir Stan, if I may share my experience on the tight barrel and length.
The suppressor of my TR got bent for reasons I don't know and bb's were hitting the inner side of the silencer. The suppressor's connection is good but I believe it should be connected better or at least protected as it is very prone to getting bent.
I installed the laylax (FF) tri-rail and hid at least covered a half of the suppressor.
As I did the external mod, I also had the inner barrel changed to a TN (tight) and used the length intended for the M4. (Thus, even if the suppressor will be bent, the inner barrel will prevent further benting.
The M4 barrel worked well, improved my range a bit and there was no need to increase the fps yet. Yes. There is a recommended formula or table in inner barrel length : fps ratio and I am looking for the article written by sir almighty.

Thanks for sharing your experience sir D7K... Now I'm afraid to attach a suppressor to my P90 as it might get bent just like yours.. hehehe...
Here is the cylinder/barrel ratio guide from FAS:
As you can see... the type-1 and type-2 cylinders overlap at 364-430mm. So for these barrel lenghts, you can use either Type-1 or Type2 clinders. Since you already have a Type-2 cylinder- then you can still use that with the M4 barrel lenght(363mm).
If you want a dedicated sniper platform.. you'll have to go with the 455mm barrel from the AK though. It has long been recognized as one of the best lengths for FPS and accuracy in an AEG. You can still conceal the inner barrel with a very long suppressor in your P90 but you'll need a TYPE-1 cylinder for that barrel though.

Sir Stan,
Thanks for the info...medyo "dig" ko na...but not fully yet. I just want to ask further, would the lengths of the Cylinders be all the same? I get the impression they are. If so, the differences between each of the types are the positions of the holes on the cylinder....ganoon po ba?

Sir Sandman (Stan),
I played this mornimg...and my RD's gearbox had some problems....just observing from the outsde of the gearbox, when I fire it, yung nozzle does not move. What are the possible causes? Tappet plate ho ba?
Also, I noticed that my RD is a lot noisier than that of my TR...parang the former would have a noise na bakal sa bakal sound ano po kaya ang source ng noise na 'to?
