So why all the resistance to yet more info on towing?. A new thread on RC Groups would do nothing other than expand the database for potential interest in large scale soaring. Steve would be able to...

Better yet here is a link to the original web page which includes plans and build log for the plane they went in An exquisite Bergfalke II

Now it's a little strange for a guy with three trailers in his driveway, a motorcycle, and a collection of large scale gliders in his shop to be crying poor mouth, does your wife know how much you...

Frankly if your goal is to have a model aerotow event at Harris Hill in the future as was tried in the past, you might reconsider the practicality of that. Full scale soaring and modeling don't mix,...

One organization not mentioned specifically by name s the HHSC, The guys who actually "own" the operations at Harris Hill. Given that there normal soaring time is being interrupted by the IVSM, when...

Just an observation on the balsa wing sheeting... Why go to the trouble of W joints inboard when you could just do a simple 45 degree splice outboard where there is little if any stress on the wing....

I am a little knowledgeable about lifepo4 cells (from reading only). since they possess such a flat discharge curve how are folks effectively monitoring them, a traditional battery checker with load...

Stephane:
OK, thanks for clarifying, kind of thought that.

Generally I have felt the same about not using BECs in the past. guess nothing has changed. The extra ounces won't hurt a fast Fox Sloper anyway

Question: if your using a regulator why do you need to drain 100MAH out of a Lifpo4 cell before flying?

since there is no "electrified scale sailplane" heading, i think this might go here, and benefit others who may just be getting started. I am no newbie to R/C or electric, but I have not...

Reading the article the object was spotted at 8000'ASL. If Denver is about 5,280 ASL, that puts the object at around 2800AGL. Ok so what model is flying that high, Only an over 4 meter sailplane, or...

Sorry had to cut my last post a little short.
to answer your specific question when annealing or re-annealing as the case may be, there are three parameters. Heating to a specific temperature. 700...

6061 comes in its' basic form, but usually is heat treated in three designations. with out going into boring metalurgy which even i don't understand, it comes 6061-0, 6061-T6, and 6061 T651. This...

I would say that 6061 is the more common grade of aluminum. used in everything from beer cans to sail masts to some aircraft structures. It's main advantage is its' weldability. T6 is just an...

cool, but the Kruk is much more interesting, not many modeled and even more funky than a Wilga. One has to wonder about the practicality. It's easy to repair wood and fiberglass, what do you do with...

and here are some high res instruments, just re-size, photo copy, mount behind clear plastic with a thin ply dash painted flat black.
I noticed when I uploaded the image the resolution was...

Some screen shots, and a link to a not so good Youtube video,(my first attempt at using FRAPS) frame rates and graphic quality are not typical of the actual program. But you can get the idea....

Len, It would be, I would say without exaggeration, a quantum leap from Aerofly, which I also have. Aerofly is a great model sim but has so many limitations and unrealistic weather it can't compare...

Apparently not! well let me see if I can get it more on topic, meaning aerotowing. You can practice aerotowing quite realistically in FSX with a few add ons ad tweaks.

There is a towing addon...

Anyone flight simming when not building or flying? Iv'e got an equal addiction for an enhanced and tweaked FSX specifically soaring. Been developing some improved airports using ADE. .I have half...

Xroadie is right i wasn't intending to belittle your efforts just set history straight. if you read my post it was in direct reference to "it couldn't have happened 1 year ago". my comeback: but it...

But 17 years ago it did happen, 1995 IVSM, Robert Lehman, Jim Blum, Chris Wahl, put on a vintage aerotow demonstration with a 5 meter Ka6E. . Not sure of the names or spelling. I was there crewing...

Steve hit the nail on the head. Kevlar is a very misunderstood material in many ways. It makes great bullet resistant vests (OOPS). That is to say when Kevlar is layered in a raw form, free from an...

The capacity for we Americans to be duped by our government and private interest lobby groups never ceases to amaze me. The NRA has done a bang up job (pun intended) of allowing almost any American...
