After pranging my Skyraider I have now decided to convert my next one to a H model which had barn door dive brakes. I tested the one servo serves three doors concept here on my now deceased Skyraider number 1. The concept proved to work perfectly as the full scale bird with no pitch changes or change of angle on the plane when deployed what so ever. The only thing you need to do is put these on a momentary button to make them go on and off as needed.

I took some better pictures of my second Super Cub wing that has L-5 Sentinal leading edge slats. These are very scale and use the 2 to 1 rule to opening to exit. They are a bit of a pain to make.

Here is a short video clip of the pin hinge Fowler flaps in flight. They worked beautiful. No flutter and very reliable.

Finally got around to a different Fowler design. Used big Robart pin hinges to simulate an external hinge. Very conventional actually, but this is now Fowler number 4 for me. This should be very fun. If they end up as robust as my number 1 design I will incorporate them into future designs as these were ten times easier to install.

Almost finished with Ralph Hofer. First time I have used Bob Dively liquid mask and sorry to say not impressed. If you leave it on too long like a week in becomes almost too difficult to take off. Still going to keep trying it, but maybe I will have to rush to cut out the sections vs doing it at a leisure.

Gary at Custom RC Parts just made me a custom stainless steel prop adapter to fit my Durafly Skyraider. It is really a work of art and Gary burned the midnight oil on this one. He even upgraded his lathe with a digital readout meter to accomplish it. Now the Skyraider has the option of using any prop I want.

I had Gary rework his magic and make a new style without the hex since I don't like the stock props for a multitude of reasons.

New Super Weapon is technically operational now. Just need to add the streamers to it so I can find it. I doubt the NVA or Vietcong would even recognize what this thing was if it landed intact. Yes, I know they were a colonial french colony, but to most of them this thing would probably be unrecognizable.

Finished the Adam Bomb release. It all came together in the end, but what a pain getting the servo to quit buzzing. I am very glad I had used a HS 50 micro servo as anything else would be complete overkill. The endpoints were set to some ridiculously small amount of throw. Next thing is the mounting of the Standard American toilet bomb.

Giving up on the Horizon Hobby Aerial Drop unit as it doesn't work with the Sonic Combat adapter. The unit never releases and all the power in the receiver goes to 1/2. I took a gamble that all the plug in modules would work with it, but with the name Sonic Combat Adapter it should have been self evident. Well, back to the Adam Bomb unit. Here is the pictures of the set up. Micro servo in that hole and Adam Bomb unit in front.

My Durafly Skyraider will soon be carrying the American Standard ordinance.

Finished the gear and not completely happy on how it turned out. I didn't bother to vacuum bag them and free hand fiber-glassed it. Not too smooth. Finally, gave up and painted them and the aluminum paint just shows every blemish. Well, it's a foamy so I guess I should be overly critical, but man I must me rusty with the glassing by hand. Next on the list will be the Horizontal Tail.

AD-1 Skyraider (2 min 57 sec)

Second flight of my AD-1. Got the ailerons under control by dialing down my dual rates to 65% and upped the Expo to 15%. Still a little twitchy in the video, but the plane felt good. Overall, a great solid flyer with what seems are no bad habits except nosing over on grass. I am going to put Super Cub stock wheels on it as they are more round and half the weight for the same 2" size 3.5 grams.

Landing gear fairings are 90% done. Not really happy with the stock SR-10 gear angle, but for now I am just going to fly with it and see if it really matters.

Finished up the landing gear extensions and very close to finishing the fairings. I also am having second thoughts about my CG location and decided to not use the SR-10 Stinson prop adapter and instead go with a lighter one. I think the CG might be a little more aft then I calculated. For now, I won't mess with the down thrust angle as -3 could be -2 depending how accurate the incidence meter really is.

Norseman 2nd flight.wmv (2 min 23 sec)

Second flight and still driving me crazy with the diving like it's still nose heavy. I know the video says tail heavy but I meant nose heavy. Third flight I removed the 808 #16 camera from where it was to move it back, but the velcro wouldn't stick anymore hence no video of the third flight which went way better. CG looks good on the ground but in the air it still needs some up trim to fly level at full power. Now I think the motor has too much down thrust and the solution is to tilt it up with some washers. I'll put the incidence meter on it later to confirm the degree.

Here are the pictures I promised. Landing gear fairing and center section of wing. Stock SR-10 landing gear with a small 1.25" extension will make it scale.

Well I decided which paint scheme to use. I can't seem to get away from ambulance planes. The cowl will be challenging. A back up plan will be to make it the 4th fighter groups grocery getter which just has a red cowl, but same aluminum overall. This 320th group U-64s was the same group Glenn Miller went down in. I have almost finished the landing gear fairings and will post pics soon.

Well I maidened the Norseman today and good news is it flew, but was nose heavy. It took a lot of up elevator trim to correct from wanting to dive. I am using a 2200mah pack pushed all the way to the back of the battery tray and that is not enough. I guess I will have to start moving stuff inside to make it less nose heavy. With 2200 it is a little heavy. My friend Chris suggested that I use a 1300mah to dial the CG in and then mount the 2200 later. Not a bad idea.

After doing some research for a book for a friend of mine I came across this hidden gem of a plane. The Noorduyn Norseman. Made in Canada during the mid thirties it looked surprisingly like the Stinson SR 10 that was sitting on my bench. After crashing the Stinson on maiden I had to buy a new wing. After flying the Stinson I realized it had the glide ratio of a check mark and wasn't to fond of flying it. So I dropped my Super Cub experimental Fowler wing on top of the Stinson fuse and it was a near perfect match. I just cut out the aft section of the wing to accommodate the bevel in the Stinson fuselage and then salvaged all the wing mounting hardware out of my old crashed wing. Less then two hours later I had a new plane. I will maiden it this weekend and report back the results, but it should fly like a Cub, but be classic in its own unique way. There is a fantastic website for the Norseman athttp://www.norsemanhistory.ca The color schemes will blow you mind and this plane was used for both civilian and military. The U.S Army/Air Force bought many of these and called them U-64 as utility/transports. All that is left to make the conversion complete on the Norseman is to take off the wheel fairing, get a new cowl and change the horizontal stab to look more scale. Oh, and paint it. That will be really tough with all the choices.
