Re: can anyone confirm this 900 rpm mod?

If you have the old yellow drozd two cap board, this would work.
It will not work with the single cap boards, since it does not have the resistors that you mention. However, there is a different mod for increasing the ROF for those, by adding a single resistor. You will get 600, 900, 1200, instead of the 300, 450, 600.

Do a search on this site for the mods.

I found this mod on the internet. Can anyone confirm this will work on a drozd? I think it translated correctly. Thanks, Mark

"Boosting the fire rate
A construction of gun enables to boosts fire rate up to 900 RPM (15 shots per second) with all drozd parts still works normal. To boost fire rate needed to do some easy modifications with electronics. If you look at bottom side of PCB, you can see a 3 flat resistors connected to pins of fire rate control switch. Using soldering iron add in parallel a 50K resistor to resistor of middle switch pin (a switch position is 450 RPM). It will result a 900 RPM fire rate, when drozd switched to �450�."
:sad:
