It's either a .91 or, as I've seen listed on some charts, a 1.0. Since I run .67s in my scale unlimited hydroplanes and they are listed as 11cc by the manufacturer, CMB Italia. Using the figures given by CMB, I can up with the following:
.67=11cc
1cc=.0609
.0609 X 15=.9136
.67=11cc
1cc=.0609
.0609 X 15=.9136

Yes Mark that airplane I was setting up permanently on floats and I did not at that time build wheeled gear for it. Since I only can get to the water only four or five times a year it proved handy to test an extended fuel system this way.
Most any senior can be hand launched even with very small engines if the proper techniques are used. Not really an advisable technique if you are learning though. About the only ones that I would not hand launch are my four engine Seniors or my latest a Senior with a .65 AX in front and a Jet turbine on top.
Here is video of my Senior with the smallest engine an OS .35AX being hand launched:

OK First the disclaimers. If you don,t already know how to fly then save this for later.
You can either work with a helper so you can keep both thumbs on the stick during launch or you can even be done alone. Before I go on thought I feel (at least with the cadet seniors) that running with the airplane before launch usually dooms the launch. Much better with the feet firmly planted or in my case brakes on.
Now to the secrets, your single launch arm (left or right) must grasp the airplane directly under the center of gravity and the technique I use to do this is with trusted helper. After starting engine I position my self facing directly into any wind and raise launch arm (I am a lefty) and my helper will only then approach me from behind with the airplane and he is instructed to place that sweet spot directly in my hand but under no circumstances to let go until I shake the airplane.
This gives me time to assure I am gripping at the exact sweet spot. Now there is one more 'secret' and this one is very important and that is the Seniors fuselage is too wide to grip simply by squeezing during the pitch your hand will just slip. That secret is to use the main gear of the tri geared airplanes to provide a non slip point wrap you pointer finger around. It in those few seconds that I make sure my pointer finger has something solid to push aginst.
After the airplane shake signal and my grip position is good I open the throttle fully with my mouth but hesitate a few seconds more and wait till the engine fully spooled up. About all that left is to follow thru just like a baseball pitcher and that arm swing right back down to the sticks. I would not hand launch a taidragger Senior unless had built some sort of finger grip or push hole into the airplane.

John, Thanks for your thoughts on the "clone" Kadets. My recently sold Sig Kadet was well built and nice and light for it's physical size. The knockoff was poorly built and made out of some strange type of wood. It had little to no real balsa. The parts were nicely lazer cut but lacked good glue joints. I added glue, reinforcements, glue, modifications, glue, balsa wood, glue, plywood, and some more glue. I feel good about the airframe now and look forward to flying it. I did a "restyle" to a taildragger with Cub style tailfeathers, dural main gear with Cub type bungies, oversize dubro inflatable main tundra tires, sprung tail wheel, functional wing struts, functional tail wires, Cub Yellow covering with black lightning bolts and black "NC" numbers, and to finish off the fake out, Piper teddy bears on the vert stab. Yea, it's a fake Cub. I have lots of real scale model Cubs in all sizes, but somehow thought a Kadet made into a fake Cub would be fun. This new, but castoff knockoff Super Senior provided the basis for this venture. Just having fun 
. I did an engine run and taxi test in my yard today and it's ready to fly. I'm pumped, can't wait for Sunday.

John, Well today I did the maiden on the Kadet knockoff with the Piper Cub clothing. Fun airplane ! First off, I was able to fool several people that should have known better with the Cub looks. Questions like "is that a clip wing Cub?" or "whose Cub is that?" let me know I hit the mark with the Cub restyle job. That's what I wanted to do. As far as the flying goes, you were right about the 11.0 lbs RTF weight not being a factor. We had to readjust the NV on the K&B 61 several times to find the sweet spot as it kept leaning out in the air and dead sticking (it glides fine). It required quite a bit of down elevator for level flight and after trimming and then re adjusting the elevator linkage between flights so the trim when centered had the needed down elevator setting in it, it flew straight and level hands off. With the K&B 61 adjusted rich enough to not dead stick any more, loops from level flight were big and without issue. Power is just right. Rolls were pretty snappy for the type and size of the plane. A small amount of up elevator at the start of the roll with a bump of down elevator at halfway and a small amount of rudder used with the ailerons made nice rolls. It would also do stall turns and fly inverted, all I could ask for out of a restyled Kadet. Of course the best thing this "Kubdet" did was slow, low flybys looking like something from from Lock Haven, Pennsylvania. It's a keeper.

Hey cool Larry glad your Kubdet is a keeper. Ya know I think the Seniors are the most kit bashed airplanes ever. There are as many different ways to approach this too some like me want the airplane to be recognizable as to what it really is but yet something else entirely and the other extreme is to completely fool the folks as to the origin.
The most radical along that line that I ever came across was some years ago at the London Bridge float fly someone from the northwest had bashed one into a twin engine floatplane bomber with very scale like nacelles. He had redone all the tail feathers with curves and done the fuse with rounded top and bottom making the airplane look like a mid wing. This one had me stumped until I came to the wingtips and that was the giveaway. It was a great kit bash and flew very well indeed.

John, I think as long as you keep the basic flight surfaces close to original, it doesn't matter what you do to the looks and style, it's gonna fly. I guess that's why kit bashing a Kadet is so successful. My co-pilot Ty, bashed a Kadet into a three engine (3 four strokes) war bird with a dropable bomb, multiple fax rockets hanging from the wing, camo covering job, and lights. It's heavier than mine by quite a bit but still flys well as long as all engines are running. I know you have an 8 engine (electrics I think) Kadet among others. If I ever bash another Kadet, I think a fax Spirit of St. Louis would be my target. I hope you're doing well and getting to fly. Cheers

I'd say go for it! If you have the plane and you have the engine, try it out! If not, get a different engine for the kadet (like a glow .52-.70 fourstroke is perfect), and then get a new plane for the 15cc gasser. Just have fun.

The two have entirely different missions, The Cadet is First and foremost is a 'beginners' airplane that is arguably The most successful RC trainer ever. Although one that can do a fine job of aerobatics. The Big Avistar is intended to be a 'Giant Scale Trainer' There is a big difference.
So Mark what happened with your Senior Cadet you already have. Did you attempt it without a mentor?????

Let's not forget the Telemaster series. The Senior Telemaster ARF is a wonderful flier! Just don't over-power it or it won't come down. We switched from a Saito .91 to an .82 and it was perfect. You can find it at Hobby Lobby's website.
