I would go with 4-OS .15fp's. There are on ebay all the time. They are light and will fly all day on 4 oz of fuel. Also they are reliable! With four engines, having them all perfectly the same rpm is not that important. I have been flying my Stafford B-24 with 4 15's for years. It wieghs 14 pounds. 90" span. The Royal B-17 should be about 11-12 pounds max. 77"span. If you put big engines it will get real heavy. it will be hard to take off, and land if it is heavy. Even with 15's it will sustain a very steep climb angle, and go very fast at full throttle and loop and roll all day too!. If you lose two on one side with big engines and if it is heavy you will have your hands full. Keep it light and you will have a good flyer! Im just talking from what I have seen over the years and my own experience.

I got a used OS .25 FSR off ebay. it was very smooth turning over but this eng was 25yrs old.
It ran about 6 mins before seizing the piston from rust coming off the bearings. It was a gamble.
If you can find a NIB that would be good.

I started looking for a new one found this one from Hobby People for $40 new +$8 shipping.

I got in 2 days. Getting ready to break it in right now.
I've got a few Magnums and ASP's (made by same people) 2 and 4 cycle and all have been good runners.

Thank you everyone for the suggestions and for pointing me in the right direction

I've been making the same B17 as you for the last 20 months (pic's posted earlier) and have decided to use 4 x SC30's 4 strokes they are about £80 here in the UK I've no doubt they are less than that in the US.They are about 225grames but you wont have to cut the cowels as much as other 4 strokes. Hope you enjoy the build as much as I am.

Progress has been very ssssllllllloooowwwww!!!
Most of the reason for this was my working conditions. I live in a trailer and had no place to work so I had to stop building my plane and create a place to build it!
So, in sequence, my first work area (yes that's a hand-me-down card table), next my work so far - ribs only, so I built myself a workbench, and of course I had to build one for the wife too - gotta keep her happy .

Royal kits are very well engineered, but they're like putting a jigsaw puzzle together. I've been working on a P-38 kit that I bought in1986, and in approx two months time I've got the tail feathers done, the wing is all framed and the pod is complete, all by building by the numbers. I figure I'll have it ready to fly by the end of the summer. It's going electric.

Hey your in my area! Maybe we can fly formation! Sorry your going electric[:'(]. The thrill ain't there if you cant lose one.

Hey Cory,

Watts wrong with electric?
[sm=idea.gif]

harryg69

My humble opinion on electrics is that, although the convienience is there, the sound smell and feel is not. After all, when is the last time you went to a real,full scale airport or took a flight in an electric plane.

I have and fly both. Just a personal feel, sound,smell thing.

I started a Royal p38 had to stop building it as I am missing parts for the fus. I am trying to get plans that show all the full size bulkhead
parts. I built the wing in three parts,so I don;t have to take it a part to put in the van.Anyway, what electric motor are you going to use?
I was thing of going electric.

Harry, if you use two strokes you need to watch this video of a royal b-17 crash back in 1993, he had 4 o.s. .25's. http://www.rcgroups.com/forums/showthread.php?t=1352459

secondly one the royal b-17 if you balance it where the plans indicate she comes out tail heavy.

I've got a partial kit the guy had built thw wing panels (glued spars and ribs) and wont respond So I'm scratch building the ribs like you, you need to look at the nacelles on the plans, thats where you will find missing rib templates needed for completion.


I'm using four o.s. .20 size four strokes and yes they are rare, out of production and sooo on....
I've currently got 2 of em used one I got nearly new for $70, the next was $127.50 including shipping my newest one is $130 untouched, in box and pending payment.

harryg69

Yes, I found all the "hidden" ribs. Lukily, altho I live in a remote area, there is a copy shop here that can scan and print up to 36" wide and any length, they can also mirror the scan for the other wing template and other half of fuselage formers. I want to keep original plans (well they are copies anyway since I bought them on ebay) but I want an untouched set to keep.

I started out wanting to put everything but the kitchen sink in this plane, flaps, bomb drop, full retracts, working turrets, lights, the kitchen sink, oh wait - no I was going to leave the kitchen sink out.

Anyway I am now thinking of a lean, light, build by holowing balsa blocks, maybe using a thinner sheeting, drilling holes in ribs and such. I'd like to keep the retracts.

With the reduced weight I hope to be able to use 4 .15's with smaller fuel tanks. I don't mind landing and refueling more often.

Hello ByJoe
I'm planning on using a pair of Turgany"s 42-50. Their rated at 1100 watts at 3cell lipo, approx 50 amp, each. The plan says 10- 12 lbs, but I build heavy. so those motors should be enough. Let me hear from you when you'r finished.

"Royal kits are very well engineered,"

Boy, that's sure a change from the days when I was building. At that time, they were a box of wood that you carved an airplane out of, the only engineering, was how to get it all in a box, and creating the graphics for the box.

They did publish a fantastically looking catalogue, though.

anyone got the color copy of the royal catalogue? the one with th p-40, hellcat, and p-61?
If you do please scan it I'd love to see it, also staples can do scanning

Hey Royal Group,
I sold my Royal Baron Kit a while back and regret it and looking for another one. I had a crashed one I was going to rebuild but the quality of the build was not worth repairing.
If I dont find one soon will have to dig into my Ziroli D-18 kit and finish it.
I did a wanted post in classified..
Take care and keep plenty of fresh sandpaper around.

does anyone have the plans for the cessna 310 Q?
I'm looking for the updated plans which would show all the formers.
Also need the b-17 plans
If someone can get a quote at either kinko's or staples I really need these asap email me ......
Thanks

Cliff Ozier

I have a set of 310 plans with the all of the patterns and build instructions that I got from us_wing 2 years ago to replace my original bug eaten plans. I know he's MIA on on ebay, does he not answer up on his website too I guess...
I don't know how fast I could get done with the logistics of dealing with Staples. how fast do really you need this? Mine are still in the shipping box, maybe I could just ship it to you and you can make a copy. maybe make a few extra copies for the group, I dunno how much this would cost. Then you could ship them back. Let me know. Cliff

harryg69

I emailed us_wing in Jan. He said he was having some problems (family stuff I think) and he said he would be back up sometime in Feb.

I'm glad you said it first Les! I too have a very hard time understing all the good nostalgia that seems to surround Royal kits. They sure as heck were not spoken of as near as highly back when they were in production as they are now. And yes, I've owned a few over the years.

Chad,

Sacrelige! Please don't say things like that.
I still have a Marutaka Bird Dog and the Bearcat I got from Tighe yet to build.
I want to believe it will be easy.[]

Chad, they may be a box of balsa you carve an airplane out of....but I got a lot further than I have on our old scratch-build thread of a Corsair from blown up Royal Plans! I actually have built the Royal kits, so it goes a long way toward success versus having to start by cutting out semi shaped blocks yourself as a first step! Let alone making your own cowl and canopy! I have yet to see a single aircraft completed from our other thread over a three year period! At least we all can see some examples of successful planes built from Royal kits. A little carving and shaping never killed anyone, and is actually part of "the hobby that was"! People are unhappy today if you have to glue two wing halves together! An entire generation of lazy computer game players is part of itl. I am surprised that you of all people would complain about an old school kit (not to say Royal kits can't be criticized on any level). If the kit is tough, what were you doing on a scratch build? - Eric

"A little carving and shaping never killed anyone, and is actually part of "the hobby that was"! People are unhappy today if you have to glue two wing halves together!"

I, for one, was not complaining. I come from the days when there were really NO kits as we know them now, and did a LOT of Autocad design and scratch build. My avatar is a modified "Joy model" that came with printed on balsa sheet for ribs, formers, etc.

I also did a scratch designed and bult Bucker Jungmeister, that I use as my avatar on that other place.

Not complaining at all Eric, just relating that back in the day the Royal kits were not considered to be all that great. At least not with the people I hung out with. The instructions were generally less than stellar, the wood was often heavy and poorly cut, they built heavy, on top of the previously mentioned issues with lots of carving and sanding. In other words they were pretty much standard '70s-'80s technology kits. As somebody who loves to build none of those issues kept me from purchasing Royal kits. What stopped me most of the time was the cost and, let's be honest, the lack of scale fidelity of the vast majority of their kits. Anyway, none of this is anything more than my own opinion and the only point I was trying to make is that they seem to be held in much higher esteem these days than when they were in production.
