Hey,

I recently got a Polarstar F2 engine,
I'm a bit troubled with my FPS consistency.
Chrono at .2gr gives me a FPS variation of 12 fps. @115 fps/ +/- 441 fps.
I've got a Polarstar MRS regulator.

I didn't yet get into the problem in detail, but what are your suggestions?

I'm working with the closed bolt setting and a semi auto delay of 2s (2sec delay rule at my field).

Because I'm working with the above settings I don't really have to look at the nozzle return delay.

What do You think?

Could be to low dp timing or bad bucking airseal.

I adjusted the dP setting like suggested by Polarstar in function of my barrel and BB weight.

What bucking do You suggest to use with the polarstar engine?

I run a Maple Leaf HotShot Buckings in both my F2 Guns, one has a MaxxModel TE Unit and the other a stock G&G HopUp. But these only work with GBB Barels (Maple Leaf Jet).

What happens if you increase your dp to 35-45?

Any follow ups on this? I'm also having issues with fps but my engine is also putting out grey goop on the internals is that normal? I've cleaned it off every time I open the gun and it always comes back.

Ps running closed bolt on helped my fps get more consistent.
