I am using the JR DMSS radios (XG8 and as of this week, also the XG11) with the altimeter sensor. The altimeter sensor isn't much bigger than a servo connector. I suspect that the majority of the weight is in the ~6-8" of wire between the plug and the sensor...

The altitude sensor provides an altitude reading on the transmitter. This altitude is referenced from the pressure altitude at the point that the receiver is turned on. In other words, when you turn on the receiver, you see 0.0 on the altitude readout on the tx. You can set the height units to be either meters or feet. The update rate is multiple times a second. Not sure what the update rate is, but you can see the altitude readout change rather quickly in the tenth of a meter value flickering sometimes.

You can also set alarms for up to three altitudes. I set these to beep when within 1 m of the target altitude. You can also set the altitude alarm to beep continuously when exceeding the target altitude ( or below the set altitude value).

The readout is on the display screen of the transmitter. You automatically get the rx voltage, in order to get the altitude, you need to plug in the altitude sensor into the data port. You also have to select "altitude" to be displayed on the telemetry readout.

I found a max altitude readout (accidentally) on the XG11, where it shows the maximum altitude achieved. Going to have to read the manual in order to get to this screen again... I found it accidentally before I put the left handed thrower protection on the scroller/selector.

Get good solid skills flying at extreme range FIRST, then engage the vario for the additional data (if you need it).

By the time you are ready to play with a vario, you likely won't want it.
I used a Pic in my Aqula XL once, was having a blast watching it get smaller and smaller. Hearing the Pic tell me 1500', 2000' . . .
Just as it was telling me 2700' a calm voice behind me said "the idea is to get the plane back." Thanks for the good advice and use of the Pic Capt'n Jack.
I do know what 150" looks like at 2700' now, about like a DLG at 300'.

I included the write up on the Lake Charles Nats planning in the hopes that there will be a better understanding for the planning that goes into the show.
I hope everyone takes a moment to thank those that GIVE their time to make Glider Camp fun.

Dan Pruss covers the class wars of the day.

Thermaler, it seems that you somehow accidentally deleted my post just before post #6. All it said was "The idea of classifying sailplanes according to square inches sounds interesting. I wonder why it was changed", and it had been there since last January, so I'm sure it was just an accident. Perhaps you can clarify what happened.

I attended the 1974 meeting at Silver Springs Maryland meeting of the National Soaring Society where AMA rules for soaring were compiled from the many rules used by the various soaring clubs. This is what I wrote about the meeting.

About the only thing arousing much controversy was the definition of Standard class. Standard class was defined as having a 100-inch span with no other restrictions by the short lived National Radio Control Soaring Society (NRCSS) in 1970. This definition was picked up by the LSF and carried over to the SOAR Nats in 1972. In 1973, the ECSS decided that they wanted a low cost class for beginner and restricted standard class to rudder and elevator only. Nobody noticed that there were no two channel radios available at that time so every radio used for their standard class models had at least three channels. After much haggling, the NSS decided to support the LSF definition of Standard class since that was what was used in most of the country.

In 1974, the Radio Control Contest Board (RCCB) voted on all AMA contest rules for every RC event. Separate contest boards for RC Aerobatics, RC Pylon Racing, and RC Soaring were not established until about 10 years later. None of the Contest Board members were sailplane fliers so they depended on the Soaring Advisory Committee and later the NSS for advice on sailplane matters but didn’t always follow their recommendations.

A rules change proposal to split Standard Class into two groups with one being restricted to rudder and elevator only was submitted to the RCCB by some members of the old ECSS. The RCCB went against the NSS recommendation and accepted the proposal to split standard class. Ironically, the new class was defined as Standard Class while the original standard class became Modified Standard Class. Within a few years, Standard class was back to the original definition established by NSRCC in 1970.
