rpm.  Marks cabin must have been a total blurr with one whole prop blade missing...
then add the pandimonium of his precious family?  I would rather not have had to

Built according to the Dan Maher and RST plans with the exception of the carbon
behind them in the rudder.  This carbon configuration I had previously flown all
over the LA basin with out communication problems.

The Sportcraft Comm antennas still check very good to excellent across the whole

So do the simpler RST's with 1/2" added to each di-pole.

Nav's stock.  How much good is it to test a nav antenna for the amount of refected
signal returned from signals being transmitted out?  The only problem I ever had
with navs were when installed in the belly they only worked about 40 miles "from" a

Dave did I ever tell you that my wife has this nice old black cat named....yeh
Blacky.  Well lately my wife is jealous because Blacky always comes to me instead of
her like in the past.  The cat is 13 and getting a little strange but mellow just
