I have always been a builder predominately, Dail. I will keep this up, as should we all. I like that I am putting in honest time toward improving my R/C flying though. I am a skier big time in Colorado ( I raced downhill and giant slalom when younger..slalom too but I found it wasn't my strong suit). I think I'll try to fly when possible this winter. I have a lot of building to do though, this winter! So, priorities change. Let the balsa chips fly! - Eric

I was fortunate to be at the Planes of Fame airshow in 2004, the last time PoF flew their original P-26 Peashooter. Not sure if they intend to keep it grounded permanently now or not but what a cool sight and sound. The Seversky AT-12 Guardsman flying wing is almost as rare and just as beautiful too!

Two rifle (.303?) caliber guns [PEA-shooter], each side or the pilot......barrel shows on big pict as a light grey tube just below 3 & 9 o'clock inside of the cowl ring.

It's too bad you can't find the Corsair any longer, I've been researching for 2 years for the scheme and scale details I want to put into a Corsair. After I saw this one it fit the bill perfectly, but as my luck would have it I was a day late and a dollar short.

Great pic Chad! It is always a difficult thing for me to decide whether it is great to see the old things flying (of course we love it when it works out), or park 'em in a museum. Some are the only surviving examples. Maybe put them in the National Air & Space Museum?
TWG...build it! Take your time, and send us photo updates! No question of building a kit of these beautifull classics (even if the kit is a "classic")!
Pit-Viper, check out a related thread on our 1/6th Royal Corsair blow-up from the original .60 size plans. You don't need to find an expensive original Royal kit to accomplish your goals! It really is easy to cut your own kit, if you have a decent little jigsaw and hobby-sized disc sander (you could buy both for the cost of an Ebay Royal kit). Obtain some good plans and trace templates of your own, or copy the plans for cutting-up. Then use some 3M spray adhesive lightly on your paper templates to adhere it to your wood stock. Cut it out on your lil' saw...sand it to the line and you have your kit! People even have construction manuals that are reproduced, if you need them. That almost isn't over-symplifying it.

Edit: Oh yea, thanks for the pics from Cap'n Blue Sky, and Smithcreek. The Pea Shooter is worth being distracted by. I don't think it ever had a chance to proove itself, but the P-40 Warhawks of the world came on the scene soon after (they themselves were obsolete soon after WWII started).

Im building the B-17 A and C versions, converted from the Royal B-17 E version...Im also using Os Wankels type 1 so I can keep the carbs under the cowls and the exhaust plumbed thru an inline tubular muffler out the same place as the real B-17s are...My problem is its coming along very nose heavy, due to the lighter tail feathers and thinner fuse, so i had to mount everything towards the back thru the bombay doors....The CG is being closely scrutinized here...

Interesting..send pics. Where did you come by four O.S. Wankels? They are an old design. I don't know what their power to weight ratio is, I would probably stick to something conservative for power. Your choice is probably aestheticly cool though. Reliability and tunability are paramount for multis. Good luck!

very interesting choice, please keep us informed about the progress of this project!
Your B17 will not be underpowered with 1.27 HP max output for 330 grams per engine but I think you will have to consider heat dissipation and fuel consumption requirements.
Heat dissipation will be the major problem as B17 cowls will not allow for very efficient cooling and these motors can run very, very hot!
About fuel, one option could be to use one single large tank, placed as near as possible from CG.
Special care should also be given to the propeller choice due to high rpm.

There is a guy close by me who cuts royal kits out of aaa grade balsa and ply. http://kitcutter.com/cut/www.kitcutt...oyal/royal.htm
seems to have a good reputation. Keith bartley has all the cad drawings for the .60 sized corsair.
However, my corsair has still yet to fly as the old bell cranks have too much slop in them for me and I plan to use one servo per aileron.

Fantastic!! I was just considering pulling out my Corsair plans and making up a list to put in for a balsa order. I hope the cost of his kit is not prohibitive. Reasonably priced I am in.

SVX,
I sent them and email to see if I can get a price quote. I will call them in the morning to see if I can get someone and let you know. Anyone else want to know prices on anything while I'm at it?

Anyone flying a Royal/Marutaka P-51 Sr.? If so, what is your all-up-weight without fuel?
I've got all of my major and most of my minor components installed and I'm coming in at 11.0 lbs.
With a wing area of 777SqIn (as spec'ed on the box) that puts me at 33oz/Sq Ft (.24oz/SqIn.) So not too heavy I hope.
I weighed it with the static prop/spinner on it, which is pretty heavy compared to the flying prop/spinner. About three times the weight, so the 4-6oz I lose with the change-over should equal, more-or-less, the weight I have yet to add with tail wheel steering cables and TW door actuators and the final clear coat (after a few last touches on the weathering/paint details/touch-ups).
Checked the CG and it comes in close. It's @ 1/2oz in the nose shy of balanced with the scale prop and some of the weight up in the nose will disappear when the flying prop goes on and tail weight will be where the finishing up weight is going in. I've got a medium sized 6.0v pack in it and currently it's just ahead of the wing so it can be moved all the way to the firewall still. Might have to add some lead up in front of the motor as well
Makes things so much easier having full access up front.
some pics of the front end installations and the finished display prop.
