Here is an older version of windmap - uses local reported windspeeds.

Here is a new version that covers the whole earth, not just the contiguous US.,31.96,512

Got the big one flown today. Elegant 700 from RCM/Pelikan that has been on my build bench for 13 months. 42 degrees with winds 8-10 mph on the leading edge of a massive winter storm. It was today or not for the next month or so.

4000 mah 3s battery
6x HS81
A9 radio and 7 channel rx

Effortless climb on ~600 watts. Single 14 minute flight due to weather. Some minor trim issues not worth working on in these conditions and a loose flap servo. 4 channel control for me today. It is not a fast handler but it should thermal dang nicely. Landing took almost the whole field thanks to 90 degree cross wind and sunken field with plane eating trees all around.

This is the re-re-maiden of my PasserX. Broken prop on the first maiden and an esc overheat on the second has made this plane a pain to get dialed in.

I am turning the 11x7 prop a little over the max rpm at full throttle (7000 rpm max) and I have had trouble with the set screw attachment. Half Throttle launch to about 100 feet for trim.

Here are two more flights on the P40 from today. I found how to make the head can record at 125 degrees rather than at 175 degrees of view. The trade off is that it costs me more band width and I have the basic vimeo. Short videos...

Both flights were on same pack. Loose motor mount cut the day short. I broke a hinge on the flap, so flying flapless for now. Back to stock prop, 7 mins or so on a 4000 pack. My field is at 4000 feet ASL, so I am about %12 down in performance compared to our sea level friends.

Number 2

Same video, loaded in HD this time. Got to the vimeo page to see it in HD

Still love this plane

Here is a video of my boy running his SWAMP DAWG airboat from Hobby King. 2s lipo makes for decent control - 3s causes too much vibration. We have a car esc setup, so it will back under power. I'm thinking 'ol dad needs one too - hey it worked for the r/c car

I am making progress in getting this micro DLG dialed in. I am rusty with launch technique - and a little stiff from too much time at the desk. So far launches are around 45-55 feet. With the 1s battery I am a little aft of design c/g - but the positive is that there is ZERO pre-set needed for launch/cruise. I have a few clicks trimmed in for thermal trim, but have yet to really work the thermals. I have gotten a 5+ minute flight, but never got up and away.

Taken with a contour POV, not the best tool for this job but it was on hand.

Nice flying Fred.

This sweet little plane got a maiden flight today. More details to follow as I have time. Looks very similar to the famous SIG Rascal - but at 1/5 the price.

AviatorPro in .25, .40, .60 size and your choice of RED or BLUE

I did not get any photos of the build, but I can easily share the issues/workarounds that I had. I have the.25 size BLUE.

1) The push rod guides do not cross at the rear of the fuse, like they should and the heavy duty wire was hard to move in the tubes. I used a smaller diameter rod.

2) I bent the tail wheel the wrong way and then glued the hell out of it. I uncoiled the strut far enough to get the wheel behind the hinge line, so the wheel turns the same direction as the rudder

3) I bought small digital servos - I should have stayed with what I know to work well. I replaced them all with HS-81, which are my gold standard for electric sport planes

4) LG, Wheel pants and cowl painted with a gloss white to make those match the covering.

5) +++ BIG PLUS +++ The hinge slots are pre-made - thank you Mr. plane guy and the wing bolt holes are pre-drilled.

6) I will need to add cooling for the esc if I plan on flying in the heat.

7) The Aviator Pro tipped over on me a few times during taxi testing - will put some kind of skid on the wing tips

8) Balanced like a champ - did not have to move anything around.

9) Still need to glue the wing together. Flew very gentle today with a friction fit. For my piece of mind I will glue the wings together.

10) BIG PLUS - the wing fits in my car while still wired to the RX, but it takes up so much room that I can't take the other .25 size planes on the same trip in my commuter car {EDIT: The Aviator can ride with the other planes with the wing detatched from the RX }

Here are a few short DLG launches by Glidermang. This is a prototype one-of-a-kind mutt DLG made from the parts of many parent sources.

The days are going to get longer, come the first day of winter... about 3 weeks and we will be on the light side again

I have been DLG-less since October, and I have been missing the spin. The TopSky 1 finally wrestled itself away from the bench troll, this week. A few scars on the wing and a new tail group installed and we are ready, right? Nope. Those darned tiny servos use even smaller servo wires. Could hardly see them in the garage, due to low angle light and long shadows. I took a little longer than I had planned to get the last little repair details finished so I flew ALES this a.m. while the epoxy was setting. The air was dense and pretty cold, though some lift was around. I found my ALES ship to have about +/- 120 feet per min descent rate. 600 feet back to the ground in about 5 minutes with as little input as possible from me.

This p.m. I gingerly tossed the TS1.c and invoked the name of my mentor. Balance seemed OK, trim took a while, but that darn plane just likes to fly. I flew from 13:30 to 15:00, grinning the whole time. I never did get out and away, but there was a 5:35 flight and multiple other 3:00+ flights. I flew until the RDS slipped off the servo. The bench troll will have some company tonight.

I did not push hard on the launches and I still had very few flights under 60 seconds. The TS1.c (third build/rebuild) will serve as my beater DLG when the TSII comes off the build bench and there will be a another experiment DLG made from parts behind that one.

What a day

Be well, amigos

I used a "get out of jail card" today and attended the Las Cruces E-Fun Fly, sponsored, hosted and nicely executed by the Mesilla Valley RC Club. Thank you guys for putting on a nice, no stress day of fun flying. The weather was perfect and there were few crashes. Glidermang demonstrated DLG and I talked up the ALES format and flew a couple of exercises to demonstrate the task. I saw a few pilots that I had not seen in 5 years - Rich L. and Jim W., I could have spent the whole day gabbing away, easily.

I flew my .25 Spitifire a few times and my old no-name V-tail glider another few times. One could not have asked for a better day flying. I bought 3 planes and sold one plane - so I'm doing my part to move the economy along.

Until next time,

Fly well,
Be well!
