Looks like pilots have another option for a RX. I usually use the 921 RX or 9300 RX for sailplanes. They fit fine. I have seen a number of AR7000 installs with the antennas folded along the RX. Not good for getting a good signal. The antennas just stick out the wrong way for a small sailplane fuselage.
The new AR7600 looks like it might be good for pilots who want a less expensive RX with the antenna oriented better for installation in a sailplane.

I have a solution that I like to replace the base A to base B cable. It's a Spektrum transmitter, receiver and Dimension Engineering PicoSwitch. The Picoswitch plugs into a servo output providing a nice remotely operated relay. See http://www.dimensionengineering.com/PicoSwitch.htm

So F3b will now be an unofficial event that will be held at the same time as 2M on July 27, 28. Make sure you get on 2.4 so that there aren't any conflicts with 2M.
Since it's not an official event, then there can probably be a contribution to the F3b team fund in place of the regular entry. Next worlds will be in China.
Who wants to make the trip to Muncie for 2 days F3b, 2 days Unlimited, 2 days F3k or RES, F3b, Unlimited?

Sorting out which tools and spare pieces to take and pack.
The team has a lot of "stuff" to get there. Fortunately with the help of 3 pilots, 3 helpers and team manager.
Checked the seating and the flight is not really full. Now only if we can convince Delta that the US Team should sit in those empty business class seats......

Tungsten ballast fits the joiners. Now I can put an extra 10 oz max ballast into the model. Some evening flying today. cross wind, just a few MPH so I could not really load up. Thursday afternoon will be another practice day. Distance and speed flying planned. Depends on the help.
Won't have to worry about the sun in the afternoon. Should be light east wind, 5-7MPH. Temps in the 70's. Not expecting any killer lift. Also makes it easier to unload at the field. Won't have to drag all the batteries as far.

Got out Saturday a little after 7AM. Put in three 10 minute duration
flights. No wind, overcast, no real activity just fly around for 10
minutes. Set up and flew a few distance flights working the 4 minutes.
Steve made it out to the field so I flew a few with base B calls and
some rain started. 15-19 laps depending on how much rain and how good
the launch was. 50% ballast, sometimes 1-2mph cross on launchs but not
much to help. Luis made it out so I could try a few speed runs. By
then the rain was starting so it really hurt the launches. Model was
silent except for the raindrops you could hear hitting the wing in
flight so I couldn't get it under 20. Around 21 in rain with no wind or 90 degrees at best. Radar looked solid yellow, orange to the west so I was packed up by 10. Good timing on packing up.
Too much rain overnight to be able to use the sod farm and more showers Sunday anyway. With the forcast wind, it would be hard to keep turnarounds in the ground.

Launching seemed to go well for both models but I need a little more practice with the Lift. The Lift color scheme is a lot nicer than the FS3, red, white, blue.....

Saturday looks like a good practice day with a bit of help. So I can set up a course and fly some measured runs.

Not thrilled with the angle of the flap RDS hardware. It doesn't look like it's good for as much flap travel as I would like. I have some 3mm rod on order to make some new wires. And I need to measure the aluminum piece just in case I have to make a new one.

Here are the bits and pieces from a Tanga and a Freestyler 3 sitting next to each other. The Tanga is a more conventionally sized F3b model while the Freestyler is on the small size. The Tanga is blue while the FS3 is red/white. The Tanga is the longer fuselage and the larger joiner.
The wing panels on both models are almost identical in weight. 578g for the Tanga and 580g for the FS3. The FS3 does also have a ballast channel in the wing. The Tanga joiner is much larger and slightly thicker but only 10g heavier, 127g vs 117g. Tails are really close in size and weight. The Tanga is 34.8g and a FS3 with the control horn added is 33.2g. The Tanga fuse is a little lighter, but when you add in the ballast tube, the Tanga is 308g while the FS3 is 290g.

Fedex guys delivered a Tanga today. Blue and white.
This one includes RDS hardware. Looks like the pin mounts in servo, aluminum piece attaches to that and the rod. Two different angles, one for ailerons and one for flaps.
Wing joiner is really wide.
V-tail is two-piece and the ball link is already installed.

For the foot switch on my winches, I use Linemaster Aquiline 971-SO switches. I've only had one microswitch fail from too much dust over the years. The best part is you can get the in colors. No black switch hiding in the grass. I have orange ones. Usual source is Newark Electronics. But I think some other winch part suppliers have them too.

A few of our soaring friends have presented us with a challenge to get fund raising going. They will be matching your contributions up to $6000 if you make your contribution, purchase raffle tickets or purchase merchandise before March.
The secret to getting good life out of your winch batteries is to keep them charged and use a good charger. For years I used the standard automotive chargers. They are heavy, inefficient, and the automatic features sometimes don't work. Plus they are bulky which is not good when hauling a bunch of equipment to a contest.
Now I use ACI Chargers. Since I have 6 batteries for 3 winches at home, I have two of the 1206CC's and two of the 1214CC's. The nice part is they do most of the charging at a constant current. They bring the batteries up to charge pretty fast compared to a normal 10Amp auto charger. I was surprised that they even helped revive some old batteries I had sitting around.
The charger uses a switching power supply so it's fairly small in size and weight. The Eastern Soaring League purchased some in 2008 to use for on flight line charging of the winches. And they also work well on the expensive batteries like the Optima's.
What solenoid to use. I use a DC Power Contactor. I've been using Stancor 586-902's a long time and they work well and are reliable. Contact material is a silver alloy, not copper. The inrush current rating exceeds (600A) what you can put through an F3b winch and the continuous duty (200A) is in the range of what flows through a winch. They are a little larger than the auto solenoids most of you are familiar with and they are more expensive.
I usually purchase them from Newark Electronics.
