Recently I tested two 12v SLA s which had been in use sequentially for some years usually recharged before going going flat, or at least within one day. Both were run down to 10.5 v with a 10 ohm load and then recharged to 14v, The Yuasa 7 AH bought 2005 was good for about 2.5 AH the UB...

Just got asked this question, didn't have a quick and easy answer. How do you explain it?

I've seen several remarks lately in Soaring Magazine and on my home club's internet forum about the characteristics of this particular sailplane. Though not directly bashing this ship, comments made seem to imply that it's a difficult or dangerous sailplane to fly. I think that's wrong. Some of...

I have read very good critics about Diana-2 but as well very bad news about it. The good news are from the people who seem to have flown the first two Prototypes. The bad rumors I heard about number-3 of Diana-2. Obviously the main difference is, that the wing position was shifted some centimeters...

Bravely bold Sir Robin Rode forth from Camelot He was not afraid to die Oh Brave Sir Robin He was not at all afraid to be killed in nasty ways Brave, Brave, Brave Brave Sir Robin. He was not in the least bit scared to be mashed into a pulp Or to have his eyes gouged out, and his elbows...

Up for auction on ebay now is an HP-18 project. It has flown 1500 hours but needs a complete rebuild. It NEEDS either wing contouring or use it as a "quickbuild" kit for a Super-18 with the fuselage, tail, wing spars and controls already built. Comes with a very good Gehrlein open heavy duty...

If a wing is replaced by a rotating cylinder, with the forward surface rotating upward, lift will be produced. The local air velocity is high on top and low on the bottom. This upward force is known as magnus effect. The information above comes from my helicopter handbook. The theory is used to...

Who is using a motorglider as a tug? Please send details! Your location. Country. Field surface, length, elevation, temperatures. What type of tug? What gliders towed? Good, bad, and ugly of using the motorglider.

I am about to take delivery of a Discus 2cT (18m only) & am requiring some polar information to program into my 302 - in particular the airspeed corresponding to a 2 m/s sinkrate. S/H do not supply performance data. Can any other owners help?

Hoping someone may be able to help. I'm working on getting my gear up and running for the coming season and want to use my iPaq HX4700. It has not been used in quite a while, so I ordered a new 3.V = 2000mAh battery. A voltmeter shows that is has juice, and seems to be charging, but the device will...

Hi, it's still winter with lousy weather in the northern hemisphere, so it is time to warm up an old discussion. I searched the forum for threads reg. Lithium-Polymer Batteries and there have been none for a while. Here are the questions: - Does anyone have real life experience with LiPo's in a...

Hey everyone. We had a fun weekend up in Utah with many gliders up in the air enjoying the amazing fall colors and mountain scenery. At the end of Friday's flight I decided to extend the flight and go play out in the weak wave lift in the valley northeast of the Logan airport. It was fun until it...

Hello, Is anyone aware of anti-collision systems (projects or products) for gliders based on GPS and short range radio? Such systems broadcast position at random times, allowing equipped vehicles (e.g. gliders) to be informed when they have a dangerous trajectory relative to other equipped...

Does anyone have any experience driving SeeYouMobile from an SN10B, using both the GPS data and the vario/wind/air data that the SN10 can now transmit to a PDA? Wondering if it is worth the trouble to have a new SN10 wiring harness made to work with my PDA. TIA, Kirk

Hi Jonathan- I assume that by the "ASA" you mean the Arizona Soaring Association and our basically unamimous voice against the "15 minute rule" and the one mile cylinder. First of all I don't understand the point that you are making since in your opening statement you say that "the contest was...
