There hasn't been much posted here on this site for a few days, so I'll catch up a little.

I've been out on Garvin Mesa almost every day that it wasn't raining (even if we got only a small sunny break on an otherwise cloudy day). The bright sunshine quickly warms the slope, and each day there would be a light, 3-5mph S wind to back it up. On the light days, I would fly the Bird of Time, and on the slope-windy days, I would bring out the Alpina.

The BOT has an amazing ability to stay in the air, even with no apparent lift. It will travel a long way and never seem to lose altitude, and when it finds a little hot air, it makes the most of it. I have to use the spoilers in order to get it to settle down and land. The grass in the LZ is about knee-deep, nice for a gentle landing.

The Alpina is amazing. It's not a thermal plane by any measure, and it likes to carry a lot of speed. I'll climb it up high for openers, then take out the camber and let 'er slide through the air. A couple of pumps gives it the momentum that it craves, and you can milk that forever, even without much lift from the slope--I'm talking about a 3-5mph wind here. Just keep it moving. There is a definite "step" where it loves to reside, and once you get it settled in, it will fly forever. It's an interesting type of flying--lift is produced at low angles of attack, and as long as you keep it there, there's lift everywhere. It's like flying an F3F-design in low-lift conditions--but with an efficient, high-aspect ratio wing, it will just keep producing lift as long as you go fast. It's a little hard to adjust to, but it works. But then, that's what alpine flying is all about. I flew it twice yesterday like that on a cloudy, rainy day.

Looks fantastic. Just started building a BOT kit with my 14 year old. Built two gliders before (ages ago). Looking forward to this (but might hit you all up with some questions.

Winds have been from the dreaded SE direction here in Salida the past week rendering most of our favorite spots unflyable. Yesterday was finally back to W-SW and rowdy with winds from 15-25 as predicted. I ripped some nice laps with my Moth up on my DS hill then descended to meet Ed Berg and Josh for some frontside flying. My 2nd Vindicator at 45 ounces is a real treat to fly. It must have covered 50 miles in the hour I flew it. All the mountain bikers passing us were treated to sloping at its' finest and I think we blew some minds with the common refrain "Are you sure it doesn't have a motor?". Back to SE today and time to get cracking on the D80.

Not much wind, but good PM thermals today, Up went the Bird of Time for two long flights. And the landing--kiss the clover.

Hey Rene:

I have Blue Mesa on my calendar for the weekend of June 19th - 21st. Please confirm the date(s). Also let me know if there's a separate thread on RCG for the event or not.

... Greg

Mike did indeed electrify the BOT a while ago....sounds like it is more than happy to carry a little extra "ballast".

Yes, I did.

It was really very simple. I found a source for a fiberglass firewall and a motor that fit perfectly. It will now climb briskly to soaring height in about 20 seconds. There is a HUGE chuck of lead and steel in the nose of the stock Bird of Time which is easily removed, and the net weight gain is almost a wash with the motor/ESC/battery. And it flies........well, like a Bird of Time! Beautiful and graceful.

I also fabricated a spoiler system for the plane, as it does not like to lose altiture and glides forever on landing approach. The spoilers are a great aid for putting it down right where you want it. But, if you have a big field for landing, it's not an issue.


If you're interested, I'll hook you up with lots of info on how to do it. Maybe I'll put together a mini-build log.....

Those spoilers are the Cat's Meow! Have Mike turn you on to the nice, cheap Turnigy motor he is using in the BOT. I've got one in my Orion and it's the best $36 spent ever.

Finally getting around to putting some work into the D80 with this crummy weather we've been having. Yesterday I got two plates of lead ballast poured at 16 oz. each, will hold off on a third plate until I've had some time with the beast to see how she carries her weight. The goal is to get the elevator servo and control horn mounted up today. Getting excited here.

So you're saying it looks so fast just sitting there on the bench that you can't get a good pic?

Heading out to Greens Peak AZ tomorrow for a bit of slopin. You western CO boyz should come down sometimes.

Nice looking site LP! How much of a time commitment is that from your place? It is so soggy up here in Salida and you can't hardly buy a west wind...time to keep building.
