Not counting aerotow, my best thermal times, 1:17:00 and 1:21:00werefrom a Hobby Lobby red rubber hi-start...witha Wanderer! That was way back in '79. Too bad I was only a LSF Level I pilot. Wish I could fly that well now

It's quite simple. Weight divided by area. (Number of ounces divided by
number of square feet.)
I have a couple of highstart stories:
It was 1985 and I had completed my first RC airplane. It was a Drifter
II and I couldn't have been happier. The radio I had was a 2 channel
car radio on an airplane frequency. Rudder was on the right stick and
elevator was on the left. Anyway, after a
My favorite high start story
involves the Infamous Flamingoid, which I once arranged to launch with the
receiver turned off. It did a pretty good launch, but popped off about
half way up, pulled out and did a series of descending swoops and then landed in
the middle of the field with

plane leaves your hand you really can't do a whole lot to help a
problem.

Bill Malvey. We went to the Fresno field to practice for Visalia. He has a high
start that is more of a zip start.
The first two involve very nice and relatively new Super V's
The first incident was accomplished by Ron Scharck. The high start was the usual red rubber and was stretched about the same distance as the previous launch, but something went wrong and the model did a large banana profile and

remember what kit it was). We checked everything out to make sure they

On video, i have footage of the Melody going about 40 feet
Yesterday I was invited to fly with some of the members of the Northwest Florida Models at their Harold field flying site. . It is one of the many sites around the Pensacola/Milton area that the NFMI modelers have access to. Harold field is about a one mile square field of grass. What a treat!

Its too windy to fly here on the east coast of Florida, so maintanence
time. (Yes, I know, what a wimp. I can and have flown contests in pretty
bad wind but why risk a plane when there will be better days soon.) The
question is about batteries. I need to replace a number of sailplane
batteries.
Personally I'd recommend the 1100MAH NiCd. They have plenty of capacity
for thermal duration. Although I own and use NiMH batteries I prefer
nicads for receiver packs.
Either technology will do but in either case be SURE to do a FORMING charge

James,
Actually, sailplanes can draw quite a bit of power, especially 6ch
planes with digital servos. I have long been convinced that the reason
for many crashes is due to catastrophic voltage drop-offs caused by
high current loads. If you've ever seen a plane that was thoroughly

George, you are confusing stalled with fully deflected under load. The

NiCD's will deliver the most PWR on demand, but offer the least watt/Kg.
