Man am I a slow old dude. I had the seniorita near ready to maiden in July 2009 !!

God please give me some extra years to build and fly


Yes, this beautiful morning the EP Sig Seniorita finally flew. When I gave it 3/4 throttle to lift off it went into a 75 degree climb
oops. It's a real floater. Some down elevator and right rudder trim was required to get it in trim. Some more down and right on the motor mount will be added.

The concrete pad at the park site where I prefer to do the maiden flights is not too big. The first landing I was reaching for the "breaks" and found i didn't have any ...duh..... she likes to roll and roll and roll on those nice wheels. Yeah, went right into the mini swamp on one side of the pad. Well more later.... dinner time now.

One day later and closing in on dinner time again. I blogged about the senorita quite some time ago (about 3/4 down my blog page) I had mentioned some concern about the "aluminum" covering and the use of 2.4ghz. The maiden flights went well with no control glitches so no prob caused by the aluminum. As usual I've over powered another plane. It has a HACKER A30-10L but going to a lower powered out runner would be counter productive. The weight of the HACKER is required and there is the throttle.

I shall apply some mid-30s US ARMY decals. I have a wing kit for the seniorita and am thinking about building another wing with flaps and ailerons finished in yellow. I could try CROW on landing approach or perhaps better at touch down. I'll also look at adding some drag to the nose wheel in hopes of making the landing roll out shorter. My last landing was with nose high and mains touching first but it still rolled and rolled too easily. It had an APC-E 11x5.5 prop. I have replaced it with a Top Flight nylon 11x4 for less speed / more thrust and nostalgia

Time to eat...bye

Well folks, I'm back !! Been a while since I blogged, I mean.
Yesterday I flew my Super Electra for the first time with a new brushed Astro 035 FAI planetary (4.4:1) motor.
P-A-L-E-N-T-Y of power.... actually too much (I know there are some who say you can never have too much power) Anyway, it flies real well and seems to have an excellent L/D. My intent was to get some smiles from the powerful little Astro motor ..... mission accomplished.

The Super Electra was originally powered by the speed 600 supplied with the kit...... power was marginal but it still flew quite well. Why is it called a Super Electra .... what's "super" about it ??? It is my second Electra and thus much improved. The chin scoop is not opened but instead there is scoop on top of the cowl. There is no longer a battery access door on the bot of the fuse under the wing. The wing is now a one piece D-Tube, graphite reinforced, SD3021 airfoil. It has one nylon bolt at the rear center that holds it on. Thus the battery is changed by removing the one screw and wing. And, it has the Astro 035 FAI planetary (4.4:1) motor, P-A-L-E-N-T-Y of power .

It will be put on a weight reduction program now with a somewhat less powerful and lighter brushless motor. And a lighter, smaller lipo will also be used.

Epilog: WOW, I noticed the date on the pic, 11-25-2007, almost four years waiting to be re-maidened

Well folks, I've had this Scorpio ThreeDee400 ARF for a number of years... Actually, I have two of them but only one put together and ready to fly. I hadn't flown it because I thought my older flying skills may have deteriorated and I do not like to crash !

A couple of Thursdays ago it was calm and so I thought, what the he**, lets see if it will fly and I can fly it. It turned out to be more of test of my flying skills than I had intended . The takeoff went just fine (I need to relinquish my Ground Loop World Champ title ). I found that as I advanced the throttle it wanted to climb .... no problem. BUT, uh-oh MAYDAY !! The 3D was real jumpy and wasn't responding to my inputs properly. Being an experienced test pilot, I quickly realized that the stupid crew chief (that's me also) had the ailerons reversed .......aaarrrggghhh.

This is where my many years of experience took over and I managed to land without any damage...wheew. Now, one of the mandatory basics that one needs to learn is how to control roll when your plane is flying toward you. There are two (perhaps more) techniques for this. One is to mentally put yourself in the cockpit and turn your body more or less in the direction the plane is traveling, while looking over your shoulder at the plane. The other is to move the control stick in the same direction as the down going wing. I use the second method and doing so has saved my ass a couple of times. In this case it was relatively easy (mentally) to

Well, I purchased a GWS PT-17 almost a year ago. I finished it about 2 - 3 months ago but hadn't been able to maiden it due to almost constant winds.

I adopted most of the suggestions in the PT-17 build threads. I hogged out the upper nose to accommodate a 3S-1P 2000Mah Lipo. The servos and ESC are placed as far forward in the fuselage as possible .... still needed 1-1/2 ounces lead in nose. The lower wing is reinforced with a carbon fiber rod. The upper has nylon filament tape on the bottom side. I sure didn't like the GWS plastic wing struts and used the wooden struts in stead from e-flightline.com . Ailerons were cut into the upper wing but not hooked up. The maiden flight showed they weren't really a benefit or needed.

The motor is an Astro Flight 020 in a 2.7:1 gearbox. The maiden flight went fairly normal...a little aileron trim and some down elevator trim. I know very well that bi-planes lose altitude quickly when power is cut. But I still managed to land short and the wheels caught on the edge of the concrete. Now, I had reinforced the gear mounting, so the gear pulled out but there was very little damage to the mounting. BTW, I tossed those funky GWS wheels and used a couple of nice, more scale like, light weight foam wheels

Nice little bi-plane that PT-17. But the GWS decals sure are ugly !! I may replace them if I can pull them off without also pulling the paint off.

Well, that's all for now folks. See the picks below

(Blogging today because we're experiencing liquid sunshine all day.)

The Minimoa is an exceptionally nice flying 2 meter EP sailplane and I highly recommend it. There are a number of changes from stock equipment that I feel are prudent as noted in the following boring detail.

Folks, the last thing in the world I need is another 2-meter sailplane....

So, why in the world did I buy the HK Minimoa ?? The truth is I was captured by the nostalgia and that cool wing shape. Also, I loved the price at $104 shipped. Actually, I sold the four "quality" (very low ) servos and so my cost was $94 net (I'm a cheap ass jerk, just ask my wife). I read the Minimoa thread and took all the "advice" with a grain of salt. It was obvious to me that replacing the stock motor was a must (as well as replacing the stock "quality" servos).

I thought it would be a piece of cake to remove the motor because of the many posts indicating loose mounting screws. Uh-oh ! Sorry about that old_dude....... they lock-tighted the set screws !!! No way an allen wrench would loosen them...bummer!! So I drilled out those little buggers...but still couldn't pull the motor. I gave the stock spinner and props to a local flyer who needed them (I'm really NOT a jerk honey !!).

Not to be stumped by any china bell motor, (after having ripped the outer shell off) I drilled out the windings and portion of the poles to give access to the motor mount screws...... The motor was then...Continue Reading

Well, as I've seemed to have done with each of my aircraft, the MIRAGE is over powered at 80 watts per pound . Sure looks as though I have a few high powered inrunners to sell in the near future.

The MIRAGE has flown many times before off a high-start but it's hard to find an area here that is large enough and isn't encumbered by a few airplane magnets (trees you know about those don't ya Jim) or rug rats. So all of my sailplanes are converted to EP power.

The Mirage hand launched with 3/4 throttle and no problems (not too much nose up under power but will mix in a little down-elevator to throttle anyway). It was later in the afternoon and the wind was coming from the same direction as the Sun !! Aaarrgg.... immediately made a slight turn to the right to avoid being blinded. The flight was uneventful.

I checked the effect of lowering the flaps ..not much change in pitch.. just slowed a little. The Mirage is NOT a slow poke floater !! It is a light weight but the airfoil is semi-symmetrical and so it likes to be flown a little faster than a "floater". The Graupner No. 93 spoilers, though comparatively narrow, really pitched the nose down when opened 90 degrees .... woah... more up elevator needed !! I have them on a switch but they really need to be on a proportional channel. I was using my Airtronics RDS8000. I'll have to setup the Mirage on the SD-10G instead.

It was fun. A lot of hawks and vultures cruise in the area. Hope to have one stop by and fly with me some time

Yep, and I like Windows 7. I didn't particularly like the upgrade procedure though. In the past, if you owned a legal previous Windows version, the upgrade procedure did not require that version to be resident on your system. I like to do CLEAN installs..... the registry gets clogged up enough over time as it is Well, Windows 7 upgrade DOES !!

New system runs just great but I have a problem with the WD Velociraptor hard drive I will need to iron out. No biggee.

Yep, I think my boot drive is about to fail. So, if I'm not online or fail to respond to your message...... I'll be putting my new system together (not sure when though).

See ya'

Later.......

Did a full verified backup this afternoon

04/24/2010

To damn many tasks to complete b4 our daily temps hit 110F
The computer acts like an Old_dude when he first wakes up....... it clinks and clanks and refuses to start..... after about 10 minutes it will restart properly if you turn it off and then back on.......needs time to warm up first I guess

04/28

Locked up a couple of times this morning !! Still runnin' .... I hope


0602

Borrowed a laptop from my daughter and will now start to build my new system. If I'm slow to respond, I'm not too used to this laptop as yet.

Well it has been a while since I've blogged. Airtronics 2.4Ghz has made me a very happy person. I've a excellent place to fly sailplanes (and others) but it gets hits on 72Mhz, multiple channels so flying there has been out of the picture unfortunately.

I have an Airtronics RDS8000 (New for $50 !!) and an Airtronics SD-10G. I took my trusty Pico Tiger Moth and changed out the 72Mhz receiver for 2.4Ghz. And, it flew without any hits ... smooth and solid at that nice flying site.

I have a Peck Polymers Prairie Bird 50 (56" w.s.) that I built a few years ago (pic below). It originally had a hot 540 brushed, geared, car motor in it. It flew O.K. but was fairly noisy. I recently equipped it with an AXI 2814/10, E-Flite 40A ESC, a Graupner Slim CAM 9x5 prop, and an Airtronics 92824 2.4Ghz RX. It flew great.. smooth and NO hits. It has a light wing loading and confirmed good thermal activity at that nice flying site. The AXI 2814/10 isn't ideal for the Prairie Bird (too high a KV rating..... my mistake).

As I said above, "Airtronics 2.4Ghz has made me a very happy person."... yeah!!


All for now.

Well, I'm busily working on my SIG Seniorita. This ones a little "different" and has a history..... .

I purchased it from an older gentleman a few years back. It was built as a sorta ARF...mostly in the bones and not covered. The old gentleman must have had declining visual acuity. I had to reset and reglue a number of joints. The flying surfaces were fairly aligned though thank goodness.

This time was before any mention of 2.4Ghz for RC use. I wanted the appearance to somewhat simulate a mid-30s Army Air Force observation type plane. I covered the fuselage with Micafilm "Aluminum" heat shrink. I should have done the wings in yellow or "aluminum" but just love transparent red (obviously ). It was built for glo power and I mounted a HP VT.25 rotary valve 4-cycle on it. Other interests (sailplanes) and circumstances meant it wasn't flown. Last year I sold the VT .25 and removed the glo accessories and 72Mhz receiver.

I started adding the electric power equipment a few months ago. I had acquired an array of Lipos ESCs and Bl motors. The AXI 2814/10 I first mounted would work well for 9" props but I wanted LOTS of thrust. The HACKER A30-12L that it now has turns an 11" prop just fine and efficiently. I'm using a T-Bird 54 ESC and a 3S-3000 (or 3S-2100) lipo. I figure it will make a gentle flying EP for somewhat windy conditions. AUW will be 63 ounces with the 3S-3000. And wing loading will be 11-12 ounces per square foot.

BUT ! , I'm really concerned about the possible impact of the "aluminum" covering since I'll be using 2.4Ghz equipment. The Airtronics 92824 2.4Ghz receiver has two antennas. I extended one vertically out the bottom of the fuse and one extends horizontally along the inside of the windows toward the front of the fuse. I guess (hope) a range check will uncover any reception problems.

Well, its been a while since I blogged (is blogged a word ??) Below are pics of my new version of the Airtronics SuperQuestor (25 years later). I finished the airframe about 2 years ago and just got around to installing the electric power system. It's a HACKER A20-20L with a T-Bird 18 ESC and a 3S-1500 15C Hecell lipo. Each spoiler is activated by a GWS PICO servo. Magnets are used to hold the spoilers fully closed.

This new Super-Q EP weighs the same as the original...amazing that it doesn't weigh more. The original had standard size servos and receiver and receiver battery. Plus, it was covered with Monokote and needed some lead in the nose to balance properly. The new Super Q EP has a JR 610M RX and two JR 241 micro servos. Plus it is covered in Litespan and Mica film. The nose has been extended 1-3/8" as compared to the original.

More later...time for dinner !

Later.... The first flight was interesting in that the SQ would nose up strongly as power was applied and I could not get a nice smooth glide dialed in. When I checked the incidence of the horizontal stabilizer and wing I found a 3-1/2 degree positive difference. I guess that's understandable as the SQ was meant to be stable floater. Since I couldn't raise the leading edge of the H-stab, I raised the rear of the wing so that there was only a 1-1/2 degree positive difference. I did realize at the time that this would also make the nose up with power on even worse . I took it out and was very...Continue Reading

Well, lets give this blog thing a try.... kinda slow day.

I learned to fly RC some 25 years ago. My first plane was an Airtronics Super Questor Kit that my bro bought for me. He advised me not to put too much "love" into building and finishing it because it probably was NOT going to have a long life . I taught myself how to fly with that Super Questor ( I had flown control line for many years and had a good understanding of flight dynamics). It actually remained flyable 'til about three years ago...... my bro was wrong..it lasted 22 years !!

I recall that I went to a park to do a hand glide first test and managed to get the wing to hit the sign with the parks name.............. the only object within 600 feet that I could have hit oh well, I then got my first experience at repairing the leading edge of a wing .

The Super Questor introduced me to R/C soaring which is still my most enjoyed part of the R/C hobby. Here's a picture of me and the SQ in 1982 or 83.......

All for now... will continue my R/C odyssey in the not to distant future.

01-27-2008
Well, I became fairly proficient at RC sailplane flight with the Super Questor and decided that I'd need to progress by adding an engine, which I did. I put a little SuperTigre X.11 on the nose of the SQ with a cox 7x3.5 gray prop..... yes, way over powered I made the SQ w/X.11 a tail dragger and learned about ground loops !! In the mean time, (while learning how to tame ground loops) I decided I needed to build a sailplane with ailerons so I could become proficient with ailerons as well. That was the beginning of building a TopFlight "METRICK" sailplane which I'll elaborate in my next blog post.
