Congratulations to Chuck Dunlap on the initial success of his
first flights.  Those of us who are years away are really
jealous.  Chuck, would you answer a few questions (I know you
have answered some of these, but I can't seem to find the info):
1.  What is the core size for your radiator?
2.  Did you use a Griffin radiator?
3.  Has your Ross gearbox been modified to handle thrust loads?
4.  If so, who did the machine work to add the thrust bearing?
5.  Lastly, is your propeller flange in the stock location or
has the flange moved forward?
6.  What did the Weight & Balance look like?

Thanks,
Ken Powell

Hi Ken, here is some data for N616RV:

Aircraft Empty Weight
            Weight      Arm     Moment
Left Gear       487     59.5    28976
Right Gear      477     59.5    28381
Tail Wheel      61      236.9   14451
TOTAL        1025   70.1        71809

Forward CG Limit: 68.70 in
Aft CG Limit:     76.80 in
Aerobatic Aft CG Limit: 75.37 in

The radiator is a custom by Griffin, 10.5"x 20.5"x 2.5" core

The Ross PSRU has not been modified for a thrust bearing.

Prop flange is set in the stock location (I don't enjoy fiberglass work -
stock cowl)
