Ok i have heard alot of things about Cub Flying. Most people i have talked to say that they are useless to fly and can only fly into the wind. I own a 82" wing J-3 and i have never had any problems with it. What is your guys thoughts.

ktiller, I have a 77" Cub. It was given to me well used. My first few attempts at taking off were somewhat hair-raising. I learned what a ground loop was. After some research here at RCU, I checked and found it was set up with toe-out on the main gear instead of toe-in. After fixing this and installing a better engine, with some right thrust which was missing, it flies like any other high wing tail dragger. Maybe it's more in need of a deft use of the rudder on take-off, but I must have gotten used to it, because I don[t even think about it now.

Mine was one of my favorite birds. Nosen 1/4 scale, a bit heavy at 22#, but plenty of power with a Quadra 42. It worked well and was capable in a mild blow until it would lift the up wind wing while taxiing. It was very friendly to fly and relaxing. Always was fun to take out, especially after it had been laid up while I flew something else.

I miss it badly. I put many hours and flights on it over a 16 year period until it nosed in HARD with radio interference. I picked up the remains and it was truely totalled. I won't be complete until I have another.

I had a world models 1/5 cub. I really liked it. I bought it cause I heard a lot of bad stuff about cubs, I had to find out for myself. I had no trouble with mine. Unfortunately it was lost due to a bad battery. I liked it enough that I'm going to build a 1/3 scale super cub that I've got plans for. I dont know why so many people dont like the cubs. Maybe they just dont know how to set them up.

we have a cub and just love it, has a saito 52 sounds good and looks good in the air. Landings are easy and take off can be a little hairy in cross winds but if thats going to stop you then you wont be flying much., my wife is wanting to get a 1/4 scale cub for the winter build, what can I say she has good taste.

I have a 1/5 Sig (as an L-4) and also a 80" H-9 on floats, and love them both. They can be tricky in the wind, but it teaches you how to fly with control in the wind after a while. Flat turns using opposite rudder and aileron, crabbing in or sideslipping on approach, stuff like that. Definitely not a basic trainer, but a great advanced one

Nothing looks finer than a side slipping cub right down to the center line on the runway. <g>

In a cross wind the Cub will side slip all on its own. I love Cubbies. They are fun, but often demand better than average flying skills in cross wind conditions. I believe a Cub is the best plane to fly when learning to use the rudder. I have noticed that after flying faster planes like warbirds and aerobats, some have to go back to the basics class when returning to the Cub. The Cub is the one critter that can turn around and bite you when you don't respect it. I have a Balsa USA 1/4 Scale Super Cub partially built that should be ready to fly in 2007. This Cub will be done in a Warbird scheme of course...LOL!

I see that you have added an additional vertical stab to the bottom of the float plane. I have been told that it isn't necessary on a J3 Cub. Have I been misled?
I know that the beaver and Cessnas need additional vertical stab but the info that was laid on me was that the CUB has ample vertical stab. Please fill me in before I blunder my first takeoff with it. I've put that additional area on my other float planes but was going to forego it on the cub. It's a balsa USA 1/4 scale and is ready to fly.

Sorry for the me-too post, but I just flew a H9 80" cub arf for the first time this last weekend. I posted more details in a H9 thread in the ARF's forum. But it's true. The cub is not a basic R/C trainer. The 80-incher has stall/snap characteristics that can burn you quickly if you don't respect it. If you learn how to finess the rudder and the elevator, you can make the cub fly very beautifully. But if you are lazy on the rudder and elevator (or aren't sure what to do with them) you can wander all over the place and possibly snap roll yourself into the ground.

This saturday I was doing a low-ish altitude loop and needed to tighten things up on the back side and whoops, she snapped on me. Somehow the gods of R/C smiled on me this weekend and I managed to save it, but both wing tips were within 6" of the ground at various points in my recovery. I was very lucky not to just spin it straight in given how I low I was when she snapped, and ***extremely*** lucky that I didn't catch a wing tip and cartwheel.

Respect the Cub, fly her with finess, stay far away from the stall regime at low altitudes, and she'll perform beautifully. I had no problems with ground handling, but you do need to be quick on the rudder to keep her tracking straight on the takeoff run.

Curt,
How do you fly that, take pictures, and recover from the spin all at the same time. Hopefully, I'll have my landing gear back on soon and we can fly side by side next time. But you have to take the pictures cuz I can't fly and take pics at the same time.

Hi Larry,

You can fly your cub next to mine any time, but only if you have a differnt "N" number. :-) For picture taking, have you ever considered a "doggie-cam"? You'd probably want to go with something light and wireless, probably lipo powered with your dogs. The trick would be to train them to watch your airplane.

Curt.

I'm having a blast with my 1/4 scale J3, 108" wingspan, OS91 four stroke, 12 3/4 lbs. When I'm feeling lazy, it will putter around the sky just like the real thing. When it's show time, the big Cub can handle some cool stunts, my favorite being a true knife edge all the way around the field. It has about 30 flights since the maiden this past winter. Hauling a big Cub around in your vehicle can be a pain. I had to make a special rooftop carrier for the one piece wing. Hope I don't push the aerobatic envelope too far any time soon.

I know about Hauling a big wing. I make my wife take her car to the airfield when we go so that i can get all my planes and wings in one vehicle. I am looking at a trailer just for my aircraft.

No, I've also heard that, I just didn't hear it until I had already put the accessory stab on. Doesn't hurt anything, though, and it tracks really well, plus it makes it look like a REAL floatplane

I had the opposite happen..jump from cub flying to a jet (Consecutive flights) and I could not figure out why the jet was flying so crappy, all over the sky, etc.....it was my Cub thumb at work!! (jets do not need rudder when flying)

I've got a heavy overpowered 1/4 scale cub. It took a long while to get used to it, even though I have flown probably a dozen different cubs. Now I love it...and I get many comments on how realistic it flies...but it takes a lot of effort! When I'm up there I like to fly it on the ragged edge of the stall - keeping the wings level with the rudder..in a stiff breeze, it will have zero ground speed (I haven't managed backwards yet..

I had a H9 80" cub and wore it out..but I tell ya, the bigger 1/4 scale cubs fly three times better. I have to really, really work at getting it to snap or spin. It will taxi the length of the runway with the tail in the air, and will not nose over. Down side it is a pain getting it set up at the field....It's all good !

***

On the ventral fin question..the real cub was STD'ed for at least two different floats (probably more now) One set required the use of a subfin for directional stability, the other did not...sorry, but I have forgotton the specific model numbers....so you can fly with it, or without it - your choice.

Thanks, Guys. I'll go without it and see what happens.

I have a GP 81 inch cub on floats and i am having trouble getting it on step and the very end of my 13/6 prop keeps getting in the water. Please enlighten me on your setup and any advise you may have. Thanks. I also have the Saito 72

My first plane was a Cub. She's still around, a bit of damage from moving into a new house. She needs a new covering job, and a few scale upgrades.

Nony are the retracts on your cub with floats functional? if so did you make them up yourself?
Thanks Rich

Sounds like one of two things. Either your floats are too far apart and the prop tip is too close to the water, or you're getting spray from the floats' wake and the prop is hitting that.

Probably the latter; I made a couple of strakes that fit the inside edge of the floats from about an inch behind the tips to about 3/4 of the way to the step. They cut down on the spray a good bit, although they're not a complete fix, they help a lot. The GP manual has patterns for all their float sizes, and says to make them from thin styrene plastic. I made mine from two layers of1/32 balsa, with the grains crossed to improve strength. I 'glassed them separately from the floats, then epoxied them to the floats and painted the whole thing.

Also note how far apart my floats are. The distance between each float's centerline is the same as the distance between the wheels on a land-Cub.

Hi Edwin,

I am based in HK and am looking at getting a World models electric cub. Was yours electric or gas?

Cheers Boyd

im getting my friends 1/4 scale cub and man its awesome!!! has a twin 4 stoke 1.08 engine 85 clipped wing cub why do u suppose they clipped the wings on a cub? for better flying characteristics? this is all for only 650 with sevos too!!

The pic with the amphibious floats is a full size...actually, I think it might be a Husky.....

It was glow. It would fly fine with a .70 sized four stroke but all I had was a OS.91 fs. Never went to full throttle. It took off at 1/3 easily and looked pretty scale with the low engine sound and the putt-putt. I'm sure it could be electified easily.
