Flex TT5 and Einstein 640

I am in need of your help here. I am using the flex TT5 with the power MC2 installed in the top of my Einstein 640 and I have spoken with the people at LPA who make these units and even with their help I can't get the pair to  on consistent basis. The flash will fire but when I try power tracking and will work and then fail as I am using center on aperture and ISO with first shot. I will make aperture, iso adjustments as needed and then sit will quit working period. The power level will not adjust at all on strobe. I am beginning  to think these things are a bigger pain in the ass then what they are worth. I don't think I have overlooked anything but someone as some input of something I could have missed that would be helpful. Thanks

I switched to using TT5's and multiple speedlights from Buff lights for most outdoor work.

The goal was to have a lighter weight setup.  I'm using the Sekonic L-478DR for control.

I've only used an Einstein in the setup once and it worked perfectly.

All is definitely not perfect with the TT5's nor the Sekonic.  I can actually get the desired light levels faster with the Buff CyberCommander + Sekonic than with the TT5's.

You have updated the FlexTT5's firmware?

Somewhat off topic.

I too use the TT5s, MiniTT1 and Speedlights for most of my outside lighting (Sekonic L-478DR) and get it setup very fast.  Using the meter or straight TTL not having any problems with the setup.  Also use their AC3 on the FlexTT5.

I am looking at purchasing 3 used Allen Bee's B1600's for a very good price with the thought about using the FlexTT5s and AC9s to control it for my outside shoots.  Looking at Paul Buff's inverter/battery to power the B1600.

But also considering purchasing one Einstein 640 with the PowerMC2 and inverter, so I am curious if others have problems with the OP's setup too.

Regards,

shutter speed?

The flash will fire but when I try power tracking and will work and then fail as I am using center on aperture and ISO with first shot. I will make aperture, iso adjustments as needed and then sit will quit working period.

What shutter speed are you using?  I.e., are you using hypersync?

The Einstein doesn't work that well w/ hypersync because of the short flash durations....

You only can do hypersync at maximum power and after around 1/800 you get a litlle band.

And do a firmware update to all MC2/TT1/TT5/MC2/Einstein... mine work flawless.

Yes, I'm up to date on all firmware.

I'm using dual SB910s for the key light with softbox or shoot-through.  Bare if I have to beat the sun.

The Mini-Lithium Inverters are awesome.  I use a superclamp and attach to the bottom of a stick or light stand.
