Latest build. This is the current status of my Sperry Messenger. I'm pretty far along. Just finished soldering up the landing gear struts and put it all together and get a feel for how it will look. Bottoms of wings and both sides of the stab are covered with polyspan using thinned (50/50) Mod Podge Matte. I am also using thinned M-P for a filler on the Poly. So far it seems to be working just fine.

I can't believe that I haven't posted about this airplane yet. I love flying it. 42" span, about 18 1/2 oz. AUW, HURC 400 Slo-Fly motor, 11x5.5 APCe prop, 1300 3s 25c GFORCE battery. I just came in from a 9 1/2 minute flight and the battery is not even warm. Right now the batt is recharging. I'll post the consumption as soon as the recharge is finished. (Finished charging - 732 maH put back in!) Take off is generally at one half throttle with about a 15 foot take off roll. If I do a full throttle takeoff, there is no take off roll, just instant catapult into the air. Half throttle loops from level flight, just pull back on the stick. Stall turns, just pull up, when vertical, hit the rudder, turn around and pull out of the dive. Couple stall turns with low slow passes and I'm a crop duster.

She is not pretty (my fault, not the airplanes). I didn't bother with the radial engine and the paint job looks like crap, but, boy does she fly. And at the power settings that I use, she flys on her wings, not the motor. Love it. Most of the flying is at 1/3 to 1/2 power. About the only time that I will use full power is to gain a lot of altitude fast for a leisurely spin back down stairs. BTW, she doesn't roll worth a crap. Get up high, apply a little up, full aileron, some down while inverted, and be prepared to pull out of a dive when she comes back upright. Don't even think about inverted. I suspect that the full scale had similar flight characteristics.

I remember this model being published many years ago in RC Modeler magazine. It thought then that it was a neat looking little airplane but I wasn't into micro stuff then (mainly because there wasn't much 'micro' gear back then. Originally it was for single channel magnetic actuator control; I didn't have one, and couldn't see buying one for one airplane. Especially when proportional equipment was much easier to maintain and fly.

After RCM published it, Ace RC kitted it with a set of their foam wings in the kit

A few months ago, I ran across the plans on the internet available for download and I downloaded a set for use 'someday'. The same site has several of the old Ace plans. Well, someday has finally arrived and I have decided to try out the Dick's Dream. As usual, I can't leave well enough alone and so will be doing some modifications. Mainly, I will try to keep the weight down a bit from the original kit design. The first thing that I have done is to build the fuselage out of 1/16 sheet balsa instead of 3/32 sheet. I intend to build the vertical and horizontal stabs as framed up structures using 1/8 square balsa instead of 3/32 sheet. The wing will be framed up using 1/16 sheet ribs and 4 1/8 inch square balsa spars with a 1/4 x 3/8 inch leading edge and a trailing edge of 3/16 x 3/4 balsa sanded to shape. I think that I will built the wing as a two piece with plug-in panels. Since I am not using the plan wing, I have designed the new wing mostly using Profili 2. The new wing will have a NACA 2414 airfoil at the root progressing to a Clark Y airfoil at the tip.

OH, also, it will be a taildragger iinstead of have tricycle gear.

A few pix to follow:

About a month ago, I looked around and I had over seven uncompleted projects going. Talk about ADD. I couldn't seem to finish anything and seemingly continuously finding something new to start. Long story short, I decided to get some of my projects into flying condition at least even if not completely finished. A mohth ago I think I had one airplane in fllying condition, my foam 1.4 meter FMS T-28. Today, I have the T-28, Fleet Bipe, Aerodrome SE5, Hobby Lobby Stinson 105, Ace All Star Bipe, a foamy SBD5 and a F-86 EDF. My scratch built Vigilante is moving along slowly with an F-14 pusher and an F-22 still in the wings waiting.

I'm also getting some flying in. This morning I got two good flights in on the T-28. I'm not overly fond of foamiy ARF's but I've got to admit the T-28 is a great flying airplane. This evening I got two more flights in on the Fleet Bipe. This Pat Tritle design is another really nice little airplane. Really nostalgic. Looks so realistic when you see the silhouette of the old biplane against the summer thunderclouds and the setting sun. It is really relaxing. Unfortunately even with my grass cut as short as I can cut it, it is still difficult to get in good touch and goes. So 4 flights today. Congratulations to me.

While I'm on the subject of flying, I'll make a couple of quick comments on the SE5. I'm not nearly as happy with this airplane as I am with the Fleet. I had thought that the flight characteristics would be somewhat...Continue Reading

Basic wing construction

This is my third All-Star. My first was in 1973 when it was first kitted. I scratch built another in late '80's or early '90's. The second one never flew. Both were glow powered.

The first one had an Enya .19 and was HEAVY and over powered but the Enya was the only engine that I had with me in Thailand. It flew well but when the power was pulled back to land, you had better duck because it was definitely coming down. It had the glide ratio of a brick. The second had an HB .12 and as I said before, I never flew it.

I recently saw a thread about another conversion for the All Star and it has inspired me to do another one. http://www.rcgroups.com/forums/showthread.php?t=1598332...Continue Reading

This is a complete change of pace from what I have been doing for a couple of years.

I stole this idea (1919 Emmaselle) from Dag214 except his is giant sized.. I call mine the EmmaLita (my granddaughter and my wife).

Mine is parkflyer sized.
37" wingspan
13 oz all up weight
2s1p 1300 lipo
motor: Hextronic 24gram 1300 kv
pull/pull cables on rudder and elevator, separate servos on ailerons
10% flat bottom airfoil (eyeball)
flying wires on top and bottom of wing.

Simulated motor is from Keith Sparks (Sparky) at www.parkflyerplastics.com. I probably should have used a 'rotary' instead of a 'radial'.

With the 7.4 lipo, I can get about 40-50 watts and that should be plenty for nice slow flying around in my yard.

I think it is ready for maiden except for double checking the CG.

My SR-22, which has been on backorder since early September, finally arrived today. I had been tempted several times to cancel my order and move on but I waited and I think that I will be glad that I did.

The box arrived via UPS in excellent condition. It was double boxed with standard brown cardboard external and the regular kit box. Everything was well taped together.

Upon opening the boxes, I found everything to be well packed, wrapped in clear plastic and taped into place to prevent unnecessary movement in the box.

The fuselage is a very well made fiberglass construction with all the necessary wood parts already installed. The tubing for the rudder and elevator pushrods is already mounted and looks very good. The nose wheel mount is already installed and ready for the nose wheel gear leg and steering arm.

The vertical stab is an integral part of the fuselage. The horizontal stab will have to be installed and then the rudder and elevator will need to be installed.

The main landing gear are a simple bolt on job to the bottom of the wing.

The wing construction is a built up, open framework of balsa. The leading edge is sheeted from the spar forward. The ailerons are already attached.

Based on the videos I have seen of the airplane flying, it appears that it would benefit from having flaps. This might be an area for modification. Also the outer leading edge is not as per the full scale airplane and this also might be an area for experimentation....Continue Reading

I received my new Aurora 9 today. It took me a while to decide to pull the trigger on this one but Len Sabato at Advantage Hobby put a price on it that I just couldn't refuse. Thanks Advantage.

I have flown Hitec equipment for years (this is my 4th Hitec radio). It really looks nice. So far, all I've done is browse through the manual. Everything looks fine so far. Lord knows when I'll get to fly it. I've found that as I get older, I don't tolerate cold very well. And old man winter has set in here.

This is a project that I started a couple of years ago and had set aside for some reason. I dug it out this winter with the idea of finishing it and it has been moving slowing along. It will be a pusher and I've set it up for a single motor but I am seriously considering changing that for a twin pusher setup. I've been thinking about 2212-06's turning 5 inch props or maybe a little less hot setup with a pair of 2212-10's swinging 6 inch props. I have a couple of -10's laying around needing a job. I don't want terrific speed, just something that looks fairly realistic as it flys by. I really like doing touch and goes so I may also go back to my original plans of adding retracts. I also have a pair of micro air retracts available.

I've been playing around with an idea lately. I have long wanted an SE5A but have just never gotten around to building one. I finally started building using a set of Cleveland plans as a basis for construction. Quite frankly, I think the plans are pretty much useless for actually building from. They have been blown up and copied too many times and the lines are very blurry. But they do very well for the use to which I am putting them.

I am building from depron with the idea of giving the airplane the appearance of being a built up structure (at least from some distance).

The wings are cut from 9mm depron and then sanded to a rough airfoil shape. After shaping, 1/32 x 1/16 strips of balsa are glued on to simulate ribs. The wings are then covered with sheer polyester fabric that I picked up from Wal-Mart. I have tried two methods of attachment. The quickest and probably the best is to use thin CA but be ready to pick a lot of glue from your finger tips. The other is WBPU. It cleans up easier but cures much more slowly. Once the polyester is attached, it shrinks easily and quite well with a Monocote iron or your wifes iron. Just don't tell her what you're using it for.

After the fabric has been shrunk tight, paint with several coats of WBPU as necessary to fill and completely seal the fabric. I have used rattle can spray WBPU and also 'brush on'. The 'brush on' is probably more effective.

The tail surfaces are done the same way but with 6mm depron...Continue Reading

I ran across this today and thought it was cool enough to post. It is an idea from Lockheed Martin for a "sonic boomless" supersonic airliner. One of you super EDF guys need to take this one on as a special project!!!!

Wow!! Finally, after 6 days, I've got my electric service back. Fortunately we have a gas fireplace. We cooked and kept warm with that fireplace. It's amazing what you can cook with just a small gas fire. Bless her heart, my wife kept us in hot food and drink for 6 days after the Kentucky Ice Storm of '09. We were extremely fortunate. Also, we were never totally out of water, although the city water tower was empty. Thank God, there were no fires. Fire protection was practically non-existent. It got down to just a trickle and we had stockpiled some water. I'm afraid that others were not so fortunate. From what I have seen in our area, many folks, especially out in the rural areas, may have weeks, not days, before their service is restored.

Well, I broke my promise to myself. I have been actively stating that I couldn't see going for an EDF. You know, the usual arguments: too expensive, too complicated, not enough power, etc., etc.

Well, I saw an ad for a new plane from a new company that I just had to give a try. Its the Lander F9F-2 Panther. The size looked good, the price looked good and the performance seemed reasonable. So I ordered one from Electric Jet Factory.

I haven't received it yet (EJF says they won't be in stock until the 12th of September, today is the 8th), but am looking forward to it. I hope that I can withstand the temptation to modify it, at least til after I have have flown in its stock form.

I guess time will tell how my foray into EDF territory goes.

To all of the great people that I have met and corresponded with this year:

HAPPY NEW YEAR


I've had the opportunity to meet and discuss RC with a bunch of really great people from all around the globe this year. I am really pleased that I came across RCGroups. And I've been introduced to a whole new aspect of RC for me (Electric Pusher Prop Jets).

Thanks a million everyone wherever in the world that you are.

I guess I have come up with my winter project. After looking a John Morgan' version of Le Phan's F-104, I think that I will do the 104 in 130% in balsa wood with foam, carbon fiber, fiberglas and some aluminum tubing as construction materials. However, in order to be a little different, I intend to convert the F-104 to the Lockheed CL-1200 Lancer. It solves some of the wing area problem of the 104 while maintaining much of the looks. It also solves my problem of wanting to do an unusual airplane which has not been modeled much.
(I saw another thread where a guy was doing the 1200 but I never saw a finished airplane).

There is not much info available on the CL-1200 as only one prototype (non-flying) was ever built apparently. I have found several sites on the internet and several books make reference to it but they all publish the same few pictures and one three view of the airplane. I have found length, height, wingspan, and wing area numbers but who can know for sure of their accuracy. It least that lets me off the hook as far as scale accuracy is concerned. Go with the available numbers. No one seems to know for sure.

About 3-4 years ago, I bought a GWS Formosa. I put the airframe together and then put it aside and pretty much forgot about it. Now that I have this new found interest in electric planes, I thought I had better finish it.

So, this morning she got her maiden flight. WOW. A ground roll of about ten feet and then skyward like a homesick angel.

The set up is a Grayson 2212-10, 7x5.5E Master Airscrew prop, 11.1v 15C lipo, 25A ESC, HS-81 servos on elevator and rudder, a GWS 6 ch NARO rcvr and 1 GWS mini servo on ailerons. I'm not sure about the all up weight but I know its well in excess of 16 oz. My little postage scale only goes to 16 and the plane bottoms out the scale. I think the recommended weight is slightly over 14 oz.

Most of the flight is at 1/2 throttle and there is still plenty of speed. Easy loops from level flight with half throttle and she floats like crazy on landing with power completely off. I cut power completely on downwind hoping for the extra drag to slow her down but it doesn't help much. Still some trimming to do. She flies slightly nose heavy although the CG is at the aft recommended limit.

The second flight was this evening just before sunset. It was just as good as this morning however I wasn't as nervous. I think this airplane will get a lot more flying time.

I thought I would post some old memories today. Kind of a change of pace from build threads and so on. I may post some other pictures from Clark at a later date. Clark AB was a great assignment. Unfortunately, I never got to go back until this past April when my wife and I took a vacation in the Philippines.

I decided to go with torque tubes for flaperon controls on the T-38. I just couldn't bring myself to hang servos on the outside (hanging in the breeze). The torque tubes are 4mm carbon fiber running through aluminum tube bushings (same as the stabilator torque tubes).

The hatch cover will be hinged at the forward edge with two Goldberg mini-hinges and fastened at the rear with magnets.

I glassed the flaperons for extra stiffness and strength. The flaperons, unlike the rest of the plane, are glassed with epoxy finishing resin (instead of WBPU). I felt like this would give a bit of extra holding power to the torque tube attachment.

The torque tubes are lightly sanded where they attach to the flaperons and the control horns. The inside of the holes of the control horns are also scored to provide more 'tooth' for the glue to attach to. The glue used us thick foam friendly CA.

I think that as soon as I have all of the control surfaces attached, I will go ahead and 'maiden' the plane. I'm getting tired and I need the incentive. Plus, if it doesn't go well, then I can give it up before I get too far along with the finishing.

By the way, the red color is primer.
