Somebody must have converted these already as they are just oversized rubberband planes. My friend has the Senior which he is already flying on glow, but would like to convert... I have a 1/2 built Seniorta that I would like to setup for E-power.

Thanks for any info

A fellow club member has a Kadet Senior Electrified. Axi 4130-16, Jeti 77, 18X10, 18 cells. It fly's great.

I have a kit built Senorita with an AXI 2826/12, 4S TanicPack battery, Castle Creation Phoenix 35, turning a 12X6. It draws 31 Amps at full throttle, and is supposed to produce about 70 ounces of thrust. The full up flying weight of the plane with battery is 3.5 Lbs. (56 ounces)

It will hang on the prop, but doesn't have much pull out power. Overall I am pretty satisfied with the plane. I did take most of the dihedral out of the wing and added ailerons.

There are a few good threads on converting this airplane:

I just finally got my battery and will fly my conversion soon. Here is the setup.

AXI 4130/16
Castle Creations Phoenix 60
APCE 17x10
Thunderpower 5S4P 8000mah
Ultimate BEC

A lot of guys convert these to taildraggers, but I decided not to (after all ALL my other airplanes are taildraggers). I got a taller main gear from TNT Landing Gear (Four Star 120 gear) and a taller nose gear from my LHS.

This should have really good, but not unlimited, vertical. It is a Kadet after all. Flight times will be 20 minutes plus.

Thanks guys for the help... And Tweet, you sure went the extra mile! Thanks!

Just a side note...

I bought my SKSita after watching an 86 year old guy land his after his first (ever) solo. His instructor was only 72 years old!!! They both acted as excited as a couple of 12-year olds. I just had to have one (to remember those young-at-heart guys).

Now you've got my interest!!!

I didn't mean to ignore your first post, but I am so new to this aspect of the hobby that I didn't know what you were talking about. Now that I have had time to let it all soak in (and with the help of your pics) I am starting to appreciate what you had posted. I like the idea of the smaller motor as (and this is my own humble opinion) this type of airplane is ment to fly on itís wing more then on itís prop.

I have mixed feelings about E-power conversions as my first E-powered plane was an Astro Sport in 1981. I had visited Astro Flight and Bob Boucher told me that this was the plane for meÖ Underpowered, over-weight = totaled on first flight! My next venture into E-power was an Electro Cub in '85Ö Better, but still underpowered and overweight. It ended up with an O.S 10 in the nose (flew like a Cub). And lastly (before getting into Park Flyers), my Electra. Better still (that big wing could carry the weight), but still so UP and OW that I have to fly with the trims just to get to altitude. Enter the Park Flyers and I am finally hooked on E-power enough to go back and try to undo the mistakes of the past.

AMA8820!!! You must have started when you were 2 years old!

You sent your Seniorita pics so here is mine.:D

I understand your fustration with the earler electric powered planes. Even if you could have gotten this a brushless motor a few years back to power this it the batteries would have added a pound or two. It would fly with another pound or two, but would not be nearly as much fun. Even the battery that is in it is special. It is a 2480 Mah, 4S pack. It is a very new cell, that can put out up to 50 sustained amps. With throttle management, we are getting 15 minute flights. That includes hang time as well and makes this a fun airplane.

And the AMA number has been around for a while, but was not originally that small. I am a contest director and the AMA offers a lower number for that.

The numbers for the TanicPacks looks good... But have you seen the new 15&20C KolKams? Their 4000mah3s2p packs punch out 60Amps in a 13 1/2 oz pack for $160. And I've heard about a 6400mah pack that puts out 11.1V at 128Amps! The specs I've seen make it just smaller in size then an old 1900mah car pack, and 4oz lighter! Amazing!!!

I weighed the Tanicpack battery I have today and it weighed in at 9 1/2 ounces. So far it has been a great little battery.

Well, I finally flew my electric Kadet Senior ARF yesterday with another flight today. No issues besides the usual shakeout problems with any airplane. First landing did take me a few passes to figure out how far out I would need to cut the engine and what airspeed to maintain to land on my relatively short strip (in front of my house).

Actual measurements using my Medusa Power analyzer were 42 amps and 830 watts on my 5S battery with the 17x10 prop, which is a bit higher than motocalc predicts (par for the course). Performance is pretty close to unlimited vertical, but probably not quite.

I'm going to take it to the flying field this weekend to see how it compares to the Saito 91 or 100 Kadets people tend to fly around here (altitude 5000'). One good thing about electric is that the motor/battery are not affected by altitude...of course the airfoils (wing and prop) are.

I'm really happy with this airplane and the conversion of it so far. It is a relaxing fun airplane to have.

Sounds like fun Tweet, let us know how it goes. The Kadet's have very light wind loading making it hard to predict the landing spot. My Seniorita really wants to float... Nice slow speed flight though....

You can predict the landing spot with practice--airspeed control is essential. Takes a bit of getting use to though.

The best full scale short field airplanes are super light wing loading airplanes like the Kadet.

Knowing how and being willing to do a slip helps.

Anyway, fun airplane. Next project is a Funtana 90 and after that a 28% Wild Hare Extra and I really thought a Hangar 9 P-51 would be fun.

No matter what, the Senior is a keeper though.

Great hobby, and I really enjoy these large scale electrics.

Randy,

One thing the Kadet Senior ARF could use is something to differentiate the top or bottom wing from one another. Any suggestions?

A large circle of day-glo , your choice of color, will help a bunch.
We find the orange and green are best

Some of my fellow club members have just used a light coat of spray paint to help.

Any kind of nice logo type graphic would work fine. What I have on the top of the Seniorita wing makes it very visible and distinctive.

have had a seniorita kit laying around to long(15 or 18 years) now I know what to do with it. May I e-mail you in the future for more info please?
