Hi
Yes that was my first plane I have flown since coming back to RC planes sans fuel. It is nimble and predictable, plenty fast if you want but will glide nicely at less than half throttle and lands dead stick or you can drive it in. It was great to get a safe flight or two in with that. It's only weakness is that it is small and light. over 10 mile winds can be a little bouncy but 3 other club members have flown it now and all thought it was a sweet flyer, one is thinking about it as a new funflyer for his fleet.
The big Seniorita, while not as beefy as my old Kadet Mark II, is bigger and can handle wind without a whimper.

The other plane in the picture is my old Sig Hummer that was 2 channel .051 now converted to 4 channel and electric. It has not had a successful flight yet since it's conversion. It was a wild hornet when on fuel and I think it may still have a lot of those tendencies. It is too much for me right now.

The last plane is the new Parkzone Ultra-mini Corsair,way under 2 oz. It is cute as a bug and can't fly in wind any better than a bug. I have not had a successful flight with that yet, but a fellow at our club tried and while a nerve racking experience, he did get it around a few small laps before declaring defeat to the 5-8mph and variable winds. I would like to try it again if we ever get some zero MPH days.

IMHO the Mark II will handle winds fairly well, Get another cheap motor and stuff it in there, You can always share the battery packs and ESC. A motor for it should only set you back 40.00 or so.

PS. I miss my Kadet Mark II. First plane I ever built and she was a beauty, to bad she tried to salute a flag pole, Came down in many peices

I got a great deal on a Sig/China Seniorita ARF. The Infinity motor I planned as a possibility for the old nitro Sig Kadette MKII I had is SUPER in the Seniorita. I am not sure that I will pursue the old nitro Kadet for a while.
I loved it for it's durability and flying ability 20 years ago. For Ice and water flying I probably won't want to fly the Seniorita. I may look for a bit more motor for the old Kadet for that stuff.

But for anyone interested, the Great Planes/Electrifly SeaWind Seaplane is really nice. I can fly that off water as easily as any other land plane on land.

Thanks for all your help and ideas in getting my old Sig Kadet off the ground again.

Exactly my thoughts. Anybody who's got this motor and can give us the true numbers?

I just finished converting an old Kadet MK II to electric.

It is used to train people to fly, so all I needed was a slow, stable plane that would give me 5 to 8 min. flight times flying a racetrack or figure 8 pattern.

I used an ElectriFly Rimfire .32 Outrunner Brushless Motor, an Electrifly Silver Series 45A Brushless Electronic Speed Control and a 3S 2200mA battery. I'm using a 13-8 electric prop.

I get pretty solid 10 min. flights. Most of my flying is done at 1/2 throttle. I did a bunch of touch-n-goes this afternoon and still managed to get in 10 min flight times.

I don't use wide open throttle, usually the plane is airborne in 20 or 30 feet with 3/4 throttle and will do a gentle climb out at 1/2 to 1/3 throttle.

Mods to the plane were: Cut a hatch on top of the cowl for the battery, it needs to go as far forward as possible to keep the plane from being really tail heavy. I have flown it at 3-1/2" CG but would not recommend it. 2-3/4" to 3" is way better. Changed the wing hold-down to a bolt-on type, added three nylon bolts. I put the rudder and elevator servos close to the CG. Further forward would be better. I used pull-pull cables on the rudder and elevator. I removed the nose wheel and put in a steerable tail wheel, with pull-pull wires to the rudder servo. I put the motor on some aluminum standoffs that are fairly heavy. I also have a large spinner to get the CG where I wanted it. I took the single aileron servo out of the wing and put two servos side by side to give me flaperons. The flaps are only mildly effective, I wouldn't recommend doing that mod, I may undo it. The rudder is really effective. I have pretty heavy fiberglass landing gear and a relative heavy tail wheel assembly.

The plane, without the battery, is right at 5 lbs.

Update for my conversion

I used an ammeter and wattmeter to check the operation of the motor. With a 13-8 prop and a Turnigy 2200 mA, 20 C battery. At full throttle, the wattage was measured at 300 watts and the current was measured at 28 amps. The voltage was calculated to be 10.71 volts. At half throttle the current was 10 Amps.

The plane can be flown at half throttle if no major control throws are used.

Roger,
That is in a Sig cadet Mark II? That sounds under powered to me.
I think a 4400 MAH pack and 450 watts would be much better, Longer flights and stronger climbs for when you need it to get out of the way of something.
JMHO.

I helped a friend do a conversion on a similar sized plane, that he built as a kid, (read very very Heavy) We set him up with 6000 MAH pack and 600 watts. He was very happy with the way it flew, He thought it was better then the Nitro results.

I don't know if you read all of my posts. The plane is NOT underpowered. It is only 5 lbs, without the battery and it is used and flown as a trainer, it is not required to fly 3-D. I have my timer set for 8 min. and it can do loops, rolls, inverted flight, touch and goes, etc. with no problems. I have over 50 flights on it so far, nothing is "theoretical."

I had read thread, I also used to have a nitro version of the plane. I understand that in E planes I tend to over power them. I also like to have 15 min of flying in a bird that size, I am glad you are happy with it, I was just saying more or less that I think you would be happier with more power and Energy on board.
To each their own. (I miss my Mark II)

BTW IF it was mine I would be probably setting it up to 500 watts, and 4000-6000 MAH pack. A little weight is not going to hurt a bird of that size, in fact that would be close to the Nitro motor and Fuel, or the original specs.

Most people probably would overpower this plane, which is okay,and 15 min. flights are normal. All of my non-training planes can fly for 15 to 40 min. with no problems. As I said, it is used as a trainer. I have been teaching people to fly model planes since 1948, right after I taught myself to fly. I found that a comfortable training flying session, for a new student, is about 5 min., then we land and discuss the flight. We usually have five or six flights per day. You can do more flights per day, or fly longer, but it may not be as effective and the student may get stressed out.

Some of my background, which may give you a clue to why I do things the way I do. I was a corporate trainer for over 20 years. I was a Systems Engineer and a Designer, specializing in Avionics, Weapons, and UAVs, for the USAF and two major aerospace companies. My primary job as a SE was to develop requirements for aviation platforms. My primary focus as a DE was to design systems that were reliable, high quality, low cost, and could be built within a given schedule and budget. To you it is okay to build one plane, make it twice as heavy, twice as powerful as it needs to be and have it fly two or three times longer than it needs to. It will be less reliable, and more expensive to fly and repair, and you will probably not even notice or care. I'm used to dealing with items that have thousands of copies that cost millions in manufacturing and development costs with the government watchdogs and my boss breathing down my neck. I apply the same SE and DE principles from work in my hobby, not because it is hard for me to do, but because it makes sense. Or cents.
