Outstanding video!!!!!! Yeah, that right wing kinda disappeared on the turns but the whole thing shows up good on the bottom.

Definitely cool stuff!!

Aircraft navigation lights are placed in a way similar to that of marine vessels, with a red navigation light located on the left wingtip leading edge and a green light on the right wingtip leading edge. A white navigation light is as far aft as possible on the tail or each wing tip.[SUP][3][/SUP] High-intensity strobe lights are located on the aircraft to aid in collision avoidance.[SUP][4]

Absolutly correct from the front. From the rear it is backwards. Install a solid white on the rear. Being a model it is fine. In reality red and green should not be seen from the rear so it in essance gives the look of of a vehicle going reverse. Red and green should only be 1 point past the beam. 11 1/4 degrees. But it is a model. So what.

You make some good points Bob! I love to see the night fliers but I believe flying after dark violates the club rules at my local field. Which is not a problem I need light to see the airplane well any way.

Its all in fun no matter how you loo at it anyways, Your club should give it some thought and reconsider at least in parkflyer apps like this neat video. Although not related to our favotite Kadets it sure is enjoyable to see. It would help the the RC fliers promoting young kids into our RC future. Add lasers and mini strobes on extra channels. Enjoy!

The land is city owned near a residential area so I suspect the city may have required the ban on after dark flying.

Another great day with my new Kadet Mk-II. Once again joined by my old Goldberg Eagle-II & Craft-Air Butterfly, we're getting into slooooooooow-speed maneuvers - not really sure if I'd call them aerobatics. Half-throttle horizontal-8's (really rather tight ones) are getting easier with the new radio, and we're now into stall turns, Cuban-8's, slow rolls (they're getting straighter), and lower-level inverted flight. Still trying to get a knife-edge to look like it should - that flat-bottom wing doesn't help with this one though.

According to my logs, she's got 8:20 in the air now - all since 8 March. These 3 planes, together, make for an awful relaxing day in the air. Love it!

flyingagin

Now Dave I know that is way to much fun. Maybe you should go change a car tire or something to make up for it..

Would love to have participated, but it will be a few months before I can look up to fly, They said 2-3 months in this neck brace. Got my first follow up appointment this afternoon. Pain levels are vary good. But I do get tied easily and want a nap, like a 2 hour nap.

My first flight of the year with my LT-40 was enjoyable. I didn't do any slooow maneuvers, I just whipped it around a bit and practiced some landings. It was mid 50's so my fingers were a little chilled, with a NNE 10 MPH breeze. I need to fix that rudder pushrod a bit, its causing the rudder to stick and makes it look funny when coming out of a turn or other maneuver, it wags its tail. I may increase its throw too, I noticed it seemed to take a bit more control to keep it straight on approach. Next time up though, provided its a bit warmer and I can get a few more RPM out of the OS, I will get back into the groove of inverted flat 8's and outside loops. I tried a few hammer heads but the upper winds were killing me, it kept blowing the plane around.

For a supposed "trainer" a few mods sure make it a fun plane.

Did you flatten the wing?

skylark-flier

Hey Jim - sure did. She's got just half the recommended dihedreal, actually a bit under that even, at 1.875", and I love it that way. There's no effort at all to keep her in whatever attitude, laterally, I want her. Of course, she won't "self correct" like a trainer should but I don't really care about that anyway - been flying too long to need anything like that anymore.

acdii - you're somewhat ahead of me with the aerobatics. I haven't tried inverted horizontal-8's yet, still getting used to lower level inverted flight actually - I'm somewhat more "conservative" than most in my flying (yeah, you can read that "chicken") and it takes a bit for me to get into inverted stuff. Shoot, I've been flying my Sr. Falcon (also built, back in 1974, with the wing nearly flat, just .75" lift at the tip) for 40 years and I'm just now getting truly comfortable with her down low on her back.

I've tried outside loops and she ALMOST makes it through them - not enough down elevator yet. Actually, the controls are mostly set the way the plans called for - ailerons have more throw though - and I'm pretty happy with that so far. I'm sure they'll get more throw as the summer goes on. Hmmmmmmm, hold one ...

Yeah, thought so. I just went down to the shop to see if my suspicions were right, and they are. My elevator trim (transmitter) is set full forward and she's flying like I want most of the time. Need to adjust the rod, a fair amount shorter to I can "center" the transmitter trim, then I need to move the location on the horn. Elevator & rudder horn are both at the center hole - need to bring the elevator in one hole closer for more throw. Both elevator & rudder have the servo-side of the rod at the outside hole already.

That's a problem of getting older, no memory worth speaking of. I'll see something at the field that needs to be addressed and by the time I'm home, I've forgotten it completely. Just now made a note to myself to correct it tonight.

You're right - for a "supposed" basic trainer the Kadet is amazing when you tweak things a bit. She CAN be flown by a rank novice, and yet she can also do the most amazing things. Love the plane, love the design (which is why I just retired my original 1973 plane this past winter).

Hmmmm, you've got a definite issue with the sticking rudder control-rod. I'm assuming you're using something like the Sullivan flex rods - you might try what I did with the Sr. Falcon some time back. I had an issue with the rudder sticking and I rolled up a bit of 400-grit carburundum paper and pushed it through the rod at each end a few times. Worked like a charm - haven't had a problem since. Must have been a burr somewhere in there that was catching.

My wife was at the field this weekend (a true rarity) and, while I was doing the hair-pin horizontal-8 turns, she made the comment that it'd be interesting to see just how slow the plane could go. She was wondering if it could do things like her favorite plane (the USMC Harrier) can do. I told her this one couldn't but another might be more able to - and she was actually receptive to that (which came as a bit of a surprise to me). I'm actually thinking about the Sr Sport EG - with interlinked flaps & slats, & barn door ailerons, powered by something like an inverted OS FS-62V four-stroke. Set-up right, she should be a definite STOL, maybe getting into the Fiesler Storch class of performance if I do it right. Might actually make a great winter-build.

Any thoughts?

skylark-flier

Aw, Ken - you're describing me with that nap bit. Came home today from playing with the horses and promptly fell asleep on the couch - 2 hours.

Geez, I'm getting old.

flyingagin

well no nap today due to first follow up with the surgeon

I am healing nicely but a mixed bag of results.

He now has more questions than answers as some of the pain is returning. The lumbar are has the same issues as my cervical area did so may need to fuse some vertebrae there. More test more specialist

I will Pm later

But I can start SHORT drives again in 2 days

I thought I'd show off my contribution to the SKB. I had a LT-40 ARF wing that had been given to me. That was married to a fuselage kit that was in my stash (its wing went to another project). It was made into a V-Tail just for fun and a tow point was put aft of the wing for glider, streamer and toilet paper towing. The engine was upped to a OS 60FS with a 12x6 prop.

The plane is about 20 oz overweight mainly due to the Dubro heavy duty landing gear and the larger .60 engine. The tail feathers wound up weighing within grams of the standard tail group. With the 12x6 prop, this airplane screams, so much so that I was wondering if I'd overstress the wings. To slow the V-Tail down, the prop was changed to a 13x5, but it was still pretty fast (and exceptional vertical) - possibly too fast to tow gliders with. A 13x4 prop is on order to slow it down even more for towing and trainer flights.

She doesn't act any differently than an airplane with a conventional tail. With that extra weight, landings are a dream, it doesn't 'flit' in a gust of wind. I'm really pleased with it to date.

Mine is setup with 1" Dihedral(wanted to make it flat but chickened out), tail dragger, bolt down wing. I may build a second wing with more symmetrical design to it, and no dihedral. Kick my throws to the max and put a 70 on it. I run a 52 on it now. If I can prop it right, not for speed, but torque, maybe I can hover this pig. I already can do a vertical climb out at take off. Makes it look like an F-15 on full burner. I will climb about 30 feet before it peters out, but is awesome to see. Saved my but a couple times when it veered on take off and I was sure it would hit a pole, This was when I was still learning rudder on take offs being a tail dragger. There is a pole mid field with the wind soock on it, and it headed right for it. I pulled back last minute and it climbed straight up and over, then kicked some down and it leveled off, hovered a bit and started moving forward. It was directly into the wind at that point.

I have done Harrier type landings, with all things a T-34. I had a H9 T-34 mentor PTS, with the wing tip things on it. I didn't like that plane much and gave it to my friend with a magnum 52 on it in trade for an OS 70 FS. I have landed that one a couple times where the wind was just enough to keep it airborne with no forward motion, and would settle it right down on all 3 wheels. One of my friends said that is just not right.

flyingagin

Bob I love the V tail treatment. Looks great. I have had 2 planes set up for towing and the rudder was all ways a worry but in flight never seemed to be a problem.

Don't be afraid to make these wings exactly FLAT! Really, the entire class of this airframe is so very stable that you really have to work very hard to put in the instability generally found in aerobatic birds.

I like that V tail mod and may try that myself.

skylark-flier

Bob, I like the overall effect - definitely high on the "interesting" meter with that V-tail. Would love to see her in the air, she looks like a screamer (for being a Kadet). Yeah, cool.

Ah, everybody should learn the joys of overpowering a bird - vertical climbs on T/O are a joy to watch, even more fun to actually do. My MidStar-40 is my best star in this - she'll climb vertically after about 50' roll, until I decide to level her out - truly impressive. The Kadet MK-II can vertically jump something over 70', then I have to bring the nose down to about a 60-degree climb, which she'll sustain all the way to the clouds. CG Eagle-II is pretty much the same way, even though it's a bit higher powered. Both the MidStar & Eagle have OS-46FX, Mk-II has OS-40LA.

Harrier-landings - - just have never had a plane that could come very close, other than my Craft-Air Butterfly, but I don't like to put her up in anything over about 10 mph breezes. Best I've ever done to a 0-speed landing would have been my original Kadet, which regularly set down with a 15-20' rollout. Shortest so far with the Mk-II is about 40' rollout.

Been comparing the Sr Sport to a standard Sr - for the past couple days. Wonderings which would be more receptive to my conceived changes. The Sr Sport would be less work (being a ARF) but I think the standard Sr might be more fun to work with, kinda bringing the structure more in line with the Sport's features and adding my "playtoys" to the wings, etc. My wife also asked about making her a twin-tail, like my old Aerocoupe, or the SIG Stratus. Not real sure about a twin-tailed tail-dragger though. Can't say I've ever seen one, other than the old Beechcraft model-18, but it might be fun to try.

The only thing about a flat wing is that they can look like they droop. I think it's always good to have a tad of dihedral.
I'm loving my Senior Sport. Your talk about slowww speed is making me think of adding some flaps or flapperons. I love creeping upwind.

N1EDM

My Feedback: (2)

That V-tail was designed precisely for towing. I'm learning all about that, too. That's the reason why I need to slow this down with the 13x4 prop. You can't tow a glider too fast.

I also recessed that Dubro landing gear and even dropped in some reinforcement for floats to mount to, but I think that the plane might be too heavy for the floats that I have. We'll see. But I expect to have a lot of fun with it strictly for boring holes in the sky, and for towing crepe streamers for the other guys to chop up, and to help it become a toilet paper bomber. I may even put a HK bomb drop on the belly just for laughs. I'm surprised that she flies so well even with being so overweight.

Thanks for the kind words. If you want to duplicate anything, let me know and I'll talk about what I went through if it will save you some time and steps.

My Feedback: (2)

I agree with Flight Risk about the flat wing and the illusion of drooping. One advantage, though, is that you can sheet across both wing halves with a single piece of sheeting and add some strength.

I am going to keep a close eye on her. If I make a sharp turn, the wings might flex a bit (I used to see that on my Sig Rascal 40). If so, I may put some struts on it to strengthen it up.
