Do these stop numbers sound right?

Its the C5 Davis
DA was 1803 Ft

The C5 model Davis is a good 100 lbs lighter than the 57 model and has better aerodynamics!

It was those numbers that had me guessing. I figured a engine that size running 8.50s would have carried more in the timers or at least close to where they were set, but unfortunately that ended in a 10.56 and 10.19, So it looks like this set up may only carry a second or so on stop.

If it were mine, I'd make the 'Stop On' time later and/or increase the RPM on the stop some so you can carry a little more time on the stop.

It is best if you can always be on the stop through the 60' timer so you have something that should stay constant run-to-run.

just bring the rpm up somewhere around 44-4600, see where you are, then if more needed bring the first (on) time out to maybe .5-1 sec

Ok Ill give this a try next time out with upping the RPMs to 4400. Would 300 RPM make a big difference?

Also Ill change Timer A1- to 1.000, would this be too much ?

I totally agree with this
was going to mention this. i like a min of 2 sec duration on stop. ratio will be better and should be more consistent.
