Status: offline 		Well I did it again......Ive been flying for about 8 months now.I seem to make the same mistake with this stupid cub.To low and to slow.Today I over shot the runway.This plane is electric and I opted fore the cheaper nmh batts.I get about 7 minutes.So I fly for 5 then land.So anyway here I come........crap to high..........hit the power........Nothing......crap......OK......shallow turn.....CRAPPPP.....tip stall......Crack as it smokes the ground.Why am I doomed to make this mistake over and over.I will fix the plane..........But I'm getting tired of it.I don't seem to have this problem with my Pitt or my Sportster.
Anyways here are some pics for those interested.Ive fixed the other side once and replaced the firewall.Also this time it took out the rudder and elevator servos.They are pooched.

Status: offline 		Ya ,You know I think its time to start making some noise.I'm sick of electrics.I'm building a corsair right now with a st 90.My buddy hacked up his leg while working on his Magester.He bumped the throttle accidentally while centering a servo,trip to the hospital and whole bunch of stitches.A couple of inches higher and his voice would have changed.At least with glow or gas you know when its running and it wont just start up on you.
Any way.just have to cover the Cub.and its ready to go.I think Ill try a low pass about 4 feet off the deck tomorrow,inverted,ya.He.he.

Cubs are not considered the most forgiving of planes, and part of that has to do with the big wing and barn door ailerons. There was a lenghthy thread about the Cub on this forum, that detailed many of the plane's bad habits. But, that's part of what's appealing about them to many. Challenging indeed, when making the flight look scale. You "fly on the wing" with a Cub, and some owners say they are better pilots because of that.

Status: offline 		I've been saying all along. For flight consistency and predictable times, fuel is the way to go. Period. There are just to many variables with electric, more than just power sources. Flying abilities and style will vary tremendously among pilots resulting in more or less current draw during a flight and unpredictable flight times. And, when you most need the power, well, it just isn't there.

I fly my electrics.. what else am I going to do with them. But, I won't be buying any new ones. I'll stick with glow.

Status: offline 		I like warbirds for the same reason some like the Cub. The idiosyncracies of the full scale plane show up in the model. You have to know the plane and how it flies and take the necessary precautions. The challenge of building and flying are what make the hobby fun. Imagine if everything flew like a trainer. I have rebuilt a few planes without plans or instructions. It is really a thrill to see something that should have been in the dumpster brought to life again. Good luck on the next flight, you'll have learned a few valuable lessons from the plane and will be a better pilot for it.

If it happens again and if you have the room, just land straight ahead in the rough. Usually does less damage than that low speed turn that always ends up in a tip stall and a cartwheel in the ground. I know its a walk, but we can all use the extra exercise!! I to prefer glow. Nothing smells better than burning glow fuel in the morning!

Status: offline 		Wow.Talk about words of wisdom.Thank you,Very much, to those that responded to my post.Wow.I have learned so much from this site its awesome.
The cub never made it out for my morning fly as I had to glass the side and didn't want to wait up all night to wait for it to dry.The Pitts and the Sportster came home undamaged .
So I finished the cub today.......Install new servos......Check......New covering........check........whats left of the windows...check........install cowl.......new spinner and prop.........check.....do systems check....check........all is good and it doesn't even look half bad.OK take plane up on back deck ,have a beer with the wife.hmmmm........This is her Idea......She has seen me rebuild this plane a few times.You can see the silver stripe on the left side as I had no black last rebuild.I painted the stripe on the new repair free hand,not the best job.But heck this is my learning plane.
If your a purist,Or a scale guy please exit this thread.I don't want to offend anyone.
Anyway.I will be flying this plane in the morning.And yes if I overshoot she will go strait .Theres a stubble field Ive been in before with minimal damage.Usually just messes up the gear.
So anyway.Heres the pics of "Franken" cub.I gotta tell you the wife and I laughed like crazy doing it.It was allot of fun ,"dare I say"rebuilding it was satisfying.And yes ,it didn't go in the garbage.

Take care everyone.

Cub Killer, your Cub looks great after this surgical procedure, I quoted the time for what you have been flying and I think that it is too soon to fly a Cub, as this plane is not intended for beginners. Do not get me wrong, I do not know about your skills, but in order to maintain a crowd immerse into our loving hobby I would recommend to fly anything else easier and then step up to the planes you already have, like that beautiful Corsair.
What ever you decide to do please have a lot of fun.

Status: offline 		Killer,
When you say "shallow turn" are you turning with ailerons or are you using rudder? If you are turning with ailerons which direction right or left? Have all of your landings been dead stick? The Cub will want to roll left at stall so if you are giving left aileron input it will just make it worse. I imagine you do not have much of a choice either way and you are doing what you have to do to avoid obstacles.
I am wondering if the esc is up to snuff. I had an electric that would work just fine until you would reduce speed and then suddenly increase the speed. It wound up being the esc, I now use gas only btw.

I will also say that you may want to try better landing gear. I have found that most "stock" landing gear is good for about two or three landings, less if you have hard landings! You can use composite or carbon gear that works well if you have adequate landing skills. The only problem with the composite is that they are very rigid and do not give much so if you have a hard landing it may take the bottom of the palne out where the gear is attached. I use good sized wire in two sections soldered together to make the gear. One wire will be formed with the axels and the other for support. Once soldered together it is strong yet flexable. Use rubber wheels too!

Well, I found out for sure what my problem was .The batteries I was using ,after only about 25 flights each have lost there ability to hold a charge.I took the plane off after the repairs and I had to use about 200 feet of runway.[good practice on the rudder]Then the battery died.So.I went and bought a 3200 lipo. The plane takes off in 20 feet.I have a good 15 mins.And I get to land with power.I seem to be able to grease her in with about 20% power then cut the power about 1 foot off the deck,flare to a perfect 3 point landing.OK,Once in a while this happens.
Who ever said the cub is not a trainer is so right .I know I need allot more practice,That Corsair I'm building will sit until I know I'm good enough to fly it.Funny this though,The e-flight pitts I'm flying says its for intermediate to expert pilots.Ive flown this plane doing rolls ,knife edges, inverted ,stall turns etc.Ive had it up 4 times and it doesn't have a scratch.Hard to believe a cub would be harder to fly than this.
Anyway.Just finished anther plane.Piper Pawnee.I'm hoping this plane will help my with my take off and landing skills.
Thanks again everyone.
