My Flashback - though for the moment I can't find any flight pics or pics with the canopy on it... . I'll post more pics when I find them.
I love this plane. Best electric flyer I own and the model I fly the most.

Some pics of my Slow Stick.
I wasn't totally happy with the stock SS so I thought I'd try to "fix" it. I ended up with a pretty fun flyer. I went a little overboard with the two aileron servos (flaperons) but whatever. It'll do loops and rolls effortlessly and other weird epiletic maneuvers, but it's still easy to handle. At very high speeds the wings flutter badly, but full throttle isn't really necessary. The only thing I don't really like about it is the Rx, which, after trying two of them, I'm pretty sure is the worst receiver made.

Clipped wing tips, full length ailerons cut into wing, 0 dihedral, strengthened landing gear, carbon fibre wing spar, nicer wheels, and other miscellaneous fixes.

Himaxx 2025-4200, 5.5:1 GB, 3S 1500mAh Tanic lipo (sometimes 2S 1250 lipo), CC Thunderbird 12 ESC, 2 Hitec HS55 servos and 2 GWS pico servos, GWS naro 6 receiver.

I got some great feedback from Dark Overlord on my Slow Stick replacement wing thread. I have made a number of decisions now.
  • The joins will be made with 1/8" ply screwed together with nylon bolts as per Dark Overlord's thread Wing build for SSV2 Dedicated AP aircraft.
  • I've modified the wing profile a bit. Joe was of the opinion that the "winglets" would produce a smaller force than a polyhedral wing. For some reason I thought the force would be proportional to the height above centre and independent of actual area. Come to think of it, I've never seen a wing with that profile, so there must be a reason. So, the current design has 25% of the wing area for each "winglet" (50% total) and 50% on the centre flat section. The angle of the winglets is now 15°, down from 30°.
I was at Home Depot today and picked up a 2' x 8' sheet of 1½" pink foam. I also found that they have a good selection of nylon screws & nuts, which kind of surprised me as I have head a hard time finding them up till now. I got the 1/4" X 20 Nylon bolts and nuts for the wing joiners. I'll pick up the 1/8" ply at the LHS tomorrow.

Another bit of advice I got was that the increased wing area might require lengthening the fuselage and/or increasing the area of the tail feathers. So my current plan is to "retire" my old Slow Stick (SS#1) and use the parts to build a new bird with longer fuse and larger tail feathers (SS#3). SS#2 will remain my "workhorse" AP ship while the new one gets built. For the tail feathers, I could use balsa if I feel like being old fashioned, but I'm itching to give Depron a try. I think there's a Canadian supplier here somewhere....

Ok then it's time to write a blog, saturday 05.02.06 i was flying my edge540 at our indoor sports centre, first damage to the fuselage, i cracked the right fuselage side, epoxied the fus.side, the plane is now more tail-heavy and better to hover, auw is now 195g
Can't wait to next saturday to have some more fun, and get the adrenalin flowing again.....

Hello, and welcome to my blog.

I'm Steve. I currently fly an x400 (another on the way), belt drive H2, and 2 brushless fixed pitches MDF and a mothed HBv2. Controlled by a Futaba 9CHP. There are still several planks in my garage though I haven't flown one in months.

I'm thinking this blog thing could be a really usefull tool, please feel free to post here, but your question/comment could be usefull as a topic in the proper forum. Replies could help others also. Lot's of good info, that would be usefull to others, is lost via PMs. Maybe blogs could be a halfway house.

Here's some pics (well now I realize I need some current pics )

Hi Johnson was fabulous when he put together his “Superwings” company. Dave Register was his profile expert, who basically convoluted a symmetrical section about a mean camber line quite successfully. Waco engineering progressed into Hi Johnson’s concepts afterwards, but with stronger (Magic) wings, while giving homage to modern profiles.

My problem with this view is our modern view is not accommodating to the fact that the average age of a sailplane pilot is currently greater than 52. You see, when an activity becomes a peak endeavor, professionalism normally enters the picture to amass financial interests [that is pitifully lacking with modern soaring]. If the soaring activity were less hostile to woodys, homebuilts, antiques, typical kits of sailplanes to be built by newbies, instead of concentrating on the perfect sailplane following full size machinery parameters, there could be a lot more interest stimulated.

Having dead air time equal to task time as we have in modern competitive soaring, makes duration conditional. Cutting launch in half while maintaining a 10 min. slot forces pilots to apply their ability of soaring pilots. How much easier is it to work lift at a full size sailplane’s altitude with a model sailplane that soars at 1/3 the airspeed, and has half the sink rate of the highly engineered human driven 18-meter machine?

Whether you fly an RG-15 at 13 ounces per foot, or a thinner Dr. Drela marvel at 7 ounces per foot, you are within a similar...Continue Reading

These day we live an extremly cold winter in Hungary . In spite of minus 10 centigrades, we didn't stopped our favorite activity, namely the electric soaring. To have an idea aboüt the conditions see the photo below:

Getting good at recycling the magnets from my dead Plantraco Bahoma cells. I killed my only two 160mAh Bahoma cells by running them down too low, so now the magnets live a second life in a 210mAh cell and a 160mAh cell from MaxAmps (nice cell). You absolutely must have a low temp soldering iron to do this -- or you'll kill the magnets. I took a bunch of pics of the process and I'll post a thread on this in the Micro forum soon. Here's a pic of my new 160mAh cell with the recycled magnets. Works great.

A bit windy over at Rancho San Antonio for my little "Q-Wing", but I got in some flying time this afternoon. Considering that she weighs 21g, has wingspan of about 13 inches, and has just a 7mm pager motor, she did pretty well.

The wind was around 7 or 8mph (I remembered to bring my wind meter thingie today) with gusts. I'd say that's the max wind she can reasonably fly in. If I kept straight into the wind, I could make slow forward progress, but if I got turned even a little bit to the side, she'd go squirting off to the side. Caught some major lift in a few spots and got her pretty high, close to 500ft I'd guess (that's high for this little plane). I'm amazed at the range of this little Plantraco 900MHz TX/RX system. Its not just for indoor!

Maybe tomorrow morning the wind will be less. All 3 of my batteries are now charged up... just waiting.

Here's some pics of my Q-Wing from a few days ago (another windy day).

I fly to make aerial photographs. Thus mission-bound, the design of my flyers is restricted to making better camera platforms. I leave scale, aerobatics, speed to others. I like them slow and stable.

For a year I flew slow sticks and still do. This elegantly versital design is well suited for me. Additionally I am constructing a regallo wing arrangement for AP and a quad-motor/prop VTOL flyer also for AP. Each of these will have their place in my photography.

I carry at least three wings with different bottom markings, selected depending on light conditions. Black shows well against a white sky, white against a blue sky and brown, hawk wing emulation when I want to fly unnoticed.

My stable uses only brushless outrunners and LiPO packs. Why settle for less?

Currently I am outfitting a tiny single axle trailer (like you see pulled behind a motorcycle) to carry three camera planes and all needed support equipment for easy mobility. I want to travel around to beautiful places and photograph them from the unique perspective that only low altitude aerials can provide. I call these views, "amazingly unique views of the familiar," and I want to someday publish a book with the title, "A Hawk's View of Humboldt."
Happy landings, Fish

Just a test. Interesting to see how many vids I can host here - always too many and not enough space.

Well let me say that I am an X RC 'er that has come back to the fold. I ( 28 at the time) started RC back in 1976 had a Futaba 6 channel system, and flew with my Dad on the weekends when I was able to get away from engineering work. Prior to RC I flew U control which was once in a blue moon; most of you know how it is when you get married.

Well I am still married 35 years now which means I and my wife broke the length of the average marriage at least 4 times already. Well the kids essentially except for one are out on their own selves. I essentially talked one of my good friends (buddy) to get into RC planes, and he is doing just that and enjoying it. We converse using messenger just about every weekend.

Anyway he is flying the real RCs while I am still flying with FMS on my PC. FMS is great, but I need to feel the breeze, sun, and mosquitoes. The slat marsh mosquitoes here in Southeast Texas are big enough to fly U Control, well maybe not that big, you know how it is with us Texans' are at times.

Money is going hither and yond except back in my pocket to purchase a radio system and materials to start building again. I am sure of that some of you have been in this situation. So I have started my own RC model relief fund and collecting every bit of dollars and wallet change to get back into flying again.

Anyway it feels real good to get started in this hobby again, to meet, and converse with some real nice people.

Hello Pilots,

I must be way behind the times I didn't know what a Blog was until a couple months ago. My youngest son (30+) told me, he knows everything he must be good he just finished a video commercial for NASCAR and will be working on one for Porsche. That may sound like fun but 16 hour days...

Some time ago I took my Bio off the net, too many strange people out there, but I will publish a revised version here:

Born and raised in NY, I remember seeing the first American jet plane XP-59 complete with a fake propeller being readied for flight. I met the man that flew the first plane to break the sound barrier, Chuck Yegger. At Bell Aircraft in Niagara Falls I worked for the German engineers from Pennemünde whom designed the infamous V2 rocket.

I was personally educated on the effort and the problems to be solved to get to the moon by Dr. Walter Dornberger who was the number one man in Adolph Hitler's rocket program. I argued with Wernher von Braun the architect of Americas race to the moon. At Bell aircraft we designed and built the first all American missile, the BELL AGAM-63 "RASCAL" it was what we call today, a cruise missile, it was ahead of it's time, the technology was inadequate and the missile did not work well. It was not all work at Bell Aircraft, three men molded my technical career, one of them Al Retzlaff taught me electronics during the work day and Morse code during lunch hour. I received one of the first Novice licenses issued.

Blog time!

Lately I seem to be less and less interestied in this hobby, maybe because of the poor flying weather and my seemingly smaller and smaller slivers of free time.

There are a half dozen or more planes that I have designed, mostly for the EDF-40, just waiting to be built. I got about halfway through the "Sliver" jet; that's sitting in pieces in my workshop waiting for attention. The MiG-25 prototype flew really well last summer (?!) but I haven't made much progress making plans for that one. Not to mention the F-4, which first flew back in the fall of 2004 - can that be right? And the Stickler, and Culprit, and Harrier and F-102 and on and on. Gotta just get through 'em one by one.

Anyway I got sidetracked recently buying and restoring some old 1/10 scale RC buggies from my youth - the Kyosho Rocky and Turbo Optima. It's amazing what you can find on eBay, and even more amazing waht some people will pay for 20 year old models!

It is kind of nice to tear down an old neglected model and clean everything up to near-new condition. I have been using an ultrasonic jewelry cleaner in tandem with an old toothbrush for this and the results are great. The contrast between the featherweight foam models I have been flying and these heavy-duty cars is really astonishing.

Interesting sites I have bookmarked lately:

After flying competition from 1976 to 1994 and winning lots of places (for one without soaring talent), I initiated the Hot Air Masters for the purpose of holding fun contests within The Denton RC Club that spilled over into postal contests.

Because the field we used for contests was a power field - that would not accept large winches (site was only 400 feet by 250 feet), we developed low launch technology that would enhance our soaring world, which was simply ignored by the larger soaring (dedicated) clubs in the area! To the point our once a month contests were rarely attended by the other clubs, whether sanctioned or not.

Our clubs skill level in handling the short launch working typical 18 min add-um-up task made us conspire to add interest to our events, like making off field landings a penalty of adding one more minute to your task time. Hey, I could enjoy flying 20 minutes plus, to score 18 minutes... You see the landing circle is 15 feet from the edge of the field - making an interesting 'sand-trap' situation. The serious Glider Guiders (outsiders) really frowned with this attitude, and ended up black balling Denton's Contests!

After spending 10 years of frequent flying in all kinds of weather (from the short histart) I was able to construct a scoring system of statistics that could
evaluate a pilot like batting average. Unfortunately, it is not flexible to unregulated open-ended spontaneous entries of data the majority of undisciplined dot of sailplane gazers would like... Thus it was unpopular!

The data picked up from flying was put into a journal titled "The Golden Age of Model Aviation", and it may end up at this site - if there is interest.

As you can see from the posting dates, the entries below were not entered on the date shown. Actually these were copied from another blog source and I thought I'd try this out to see if I like it better. I do, so I will be dropping the other blog.

I posted a question on the AP Forum on a new thread, Design for Slow Stick replacement wing. We'll see what responses I get...

The Slow Stick replacement wing design continues apace. The stock wing is around 500 in² and I'm thinking of bumping it up to about 700. I don't know yet if I need to increase the tail feather areas or increase the fuselage length. Please post any ideas you might have in this area on the replacement wing thread. I have an old Slow Stick (sp400, NiMH) that I can always reconfigure for the new wing (and upgrade the power system) if necessary.

I'm planning on hitting the local Home Depot tomorrow to pick up some foam. Below is the current state of the design...
