I hope I don't die to soon, I have a lot of work to do. Your right though, when the old guys are gone they take a lot with them, really doesn't matter. not that many new guys to share it with and it's soooo much fun. "Ok", wheres my I Phone.

LOL. Don't we all, live long and prosper. As for the rest, well, I don't feel it is so much our abilities that is being lost but rather a type of mentality. A mentality of figuring things out and how things work, that is the base of our abilities the hands just follow suit. But the hands are use to it for that is what they have been doing. Now a days folk are getting CTS from pushing buttons to much.

Cubs seam to always bring up debate at the fields I fly at. Some guys like them, some don't and some really like them. I have flown a few different typs of planes in my short time in this hobby. I have found Cubs to be one of the more challenging planes to fly and require more attention then planes like 3D planes or sports planes. I have owned 3, and crashed one. Yes they are slow flyers but the reqier skill.
One of the reasons I like the cub is its challenges. My 100cc 3D Sbach was the easiest plane to fly I have ever had, it required the least attention to fly, relitivly speaking. I find them to be very interesting and a great frame to build off of to personalize one to the individual.
Yes the basick J3 is everywhere but with the super cub, carbon cub you can really have some fun in indavidualizing one.
Anyways I can't wait to see Leroys cub all done up like his spaicewalker.

Speaking of figuring things out, I think I have a handle on mounting the tail parts, with the mounts and horn soldered to their respective tubes I put it together to see how well it's going to work. I use led free silver solder and a micro torch to do it with, it's great stuff and strong. For those that don't know, brass does not shrink, bow or deform when soldering it.
Putting it together and setting it in place and it was looking good, elevator is doweled to the stabilizer.
While there is some fit up of the fuselage tail post the horn will be easy to get at and will have a hatch should it ever need service. Nothing is bolted down yet and there is some fit adjustment where the stabilizer meets the body but I knew it would need that. Once that is done and bolted in place all the tubes will be drilled with the dowels in them and the dowels pinned to their attachments with 1/8" hardwood dowels, no way tor any of this to fail.
I put the rudder in place just to see how it all looked, I had made the lower rudder mount 3/8" taller than the plan shows, after cutouts to clear the mounts are made it will glue directly to the plate and the front post will go in a receiver socket which will make it a lot stronger than the plan way of doing this.
It's really going to be nice, I'm really liking doing this, who said it wasn't fun.

This may be a stupid question, all shoot, I just realized I was looking at it wrong. Look's great. That is the same method I used on a Waco.

Tony so many guys just build out of the box and they are good builders, I have asked some , why didn't do the stitches or finish the cockpit (nice looking planes too) they all said the same thing, they just got burned out and wanted to fly it. All that is ok but wondered why they showed up at a scale meet where they get judged. I think if it's supposed to be scale it should look that way, not that it really matters. still nicely built.
There's that personalized building preference, go fly and enjoy it is what matters most. I like the "holly crap, come look at this", guess it's a pride thing, sure puts a
on my face.

Leroy, I know what you mean about the scale appeal. I have found I just can't fly a fram for the sake of just flying, I'm not a just go fly it kind of guy. A plane has to have as much if not more ground appeal as it does have fly ability. Yes it is a pride thing. I have never been to a scale meet/ competition and would like to at some point. I don't like ARFs at this point but some times I just don't want to build and need a plane to fly. Most if not all the ARFs I have done I striped the covering and modified and scaled it out as much as one can with an ARF. Your cub will be a winner for sure.

Leroy, it is plain to see that you have spent a lot of time thinking about the details on this plane. It is a joy to watch as this project progresses. I think that your cub will garner a lot of attention at any flying field... I love the brass work- Bravo!
I too love to spend time in my workshop, I don't know how I would cope without that release for me.

Leroy,
Nice build and lots of good tips to learn from here in your thread. I like that yours will be a SC; I've got one going mysel (old 1/5 Adrian Page kit).
On the subject of flying the Cub, while it is naturally a slower flyer which does give you more time to work through your flight/maneuvers, I think it is actually one of the more challenging models to fly "right." Getting the turns coordinated when your making circuits in the pattern, approaches, and especially landings... tough and rewarding when you do get it right. It's not a plane that "flies on rails" like most of the acro models. It doesn't go where you point it. It's infinitely easier for me to grease an Edge in than get a smooth landing with a Cub.
It can be relaxing if you are just putting around the sky for some flight time, challenging if you are really trying to do a scale flight from takeoff to landing.

Lars, I agree 100% with you. An edge, extra and any other 3D plane is a piece of cake to take off, fly and land compared to a cub. Some fly Cubs like an RC plane, full throttle on take off, go vertical, yank and bank, then bounce the landing with a wing tip scrape as you loop on the ground. To fly a cub scale like with a few added fun things like one wheel touch and goes, nice strait scale take offs and landings is much harder to do then most planes.
A cub can be difficult to take off in a cross wind, and landings can get tough to not bounce it. I have rarely seen pilots fly Cubs like Cubs and I aspire to do so with my SC.

I am getting ready to setup my flap servos and linkages, what is the best way to setup the servo and switch to get the best setup?
I have always set the servo arm at the up position so when I flip the switch for full flaps I get the full throw of the servo but my half flap position is always off and hard to get both flaps linked up. Should I center the servo on the half flap position and Then adjust the linkage in the up position and end points for the full down. Just trying to find the best and corect way to set up my flap servo and servo arm position.
I have my flaps on the right side slider.
I am asking here because you all are the smartest bunch.
Thanks
TB
