I had something similar happen a few weeks ago. Nexstar was taking off, it got squirly at the end and then some nice wind hit as it lifted off. It shot straight up in a vertical and was still climbing. At about 25 ft right wing dropped. I didn't panic and waited to see what it was going to do. I just let it fall like in a stall turn. When the nose dropped I gave it a little up elevator and it leveled off and pulled out of it. Granted, I was now going the wrong way but I learned from it!

It is like a condition that can occur when flying full size planes. You get the nose up to a certain point and the plane slowed down and there just isn't enough power in the machine to pull straight out of it, you HAVE to drop the nose and let the wing fly (not much usually)and accelerate but you have to break the stall and it you are low it goes against everything in you to do it. Only thru training and discipline and practice will it come to you. Practice slow flight at a safe altitude. The major airlines(and others) practice these maneuvers in the simulators because it is too dangerous in real life but the training has saved many lives.
In a condition like Bubba described if you would have used rudder instead of aileron it would not aggravate the wing stall but again that take experience you don't have yet. As I have said before, Don't rush. It will come. It is your youth that doesn't want to wait, I was the same way.

Bruce88123 said "Don't know what Stik-n-Rdr was talking about when he said full size pilots found using the rudder was un-natural but I doubt he knew what he was saying either. Something you pick up in just a few hours of training and get better as you go of course, like anything else in flying. Un-natural, give me a break. "

Bruce, I was just stating my opinion. I don't profess to be an expert full size pilot but do fly. Just like I do in the real planes, I must consciously remember to use the rudder when flying RC and have found through discussion that it's a weak point among full size pilots (professionals excluded, of course). Sometimes it is a subconscious, instinctive control I have over the plane from hours of experience. Most of the time, however, I must line up long on final and experiment to watch the cause/affect yaw action that is occurring from my stick movements on those brisk crosswind days. Maybe I will be a natural like you someday. I'll keep trying for sure because after all, practice makes perfect.

Guys, thinking about it, I was in a huge hurry and probably was my fault. Thats one thing i HAVE to learn. Not to get into a hurry. That new table will be good. I think the plane will now be a taildragger. One more question. The balsa on the bottom of the plane, when the landing gea came out it ripped off, Should i even worry about it? I was just going to put some tape on it. Anything else i should know? Will start rebiulding that sing tonight.

If it's possible tack the sheeting in place with thin CA then either coat it in thin CA OR epoxy.

Next since your converting it to a taildragger use a scrap piece of ply to make a LG mount to be epoxied inside the fuse and coated with epoxy so you can bolt your LG to it.

Can you get us some detailed pics so we know whats the real extent of the damage is?

Landing gear mounting plate should be plywood, 1/4" probably. Put some doublers on the fuselage sides (1/8" ply) to support it. Install 1/4" T-nuts into plywood and use 1/4" nylon screws to mount the gear to the plywood. On a bad landing, all you should do is snap the screws. Keep a few extra screws on hand and you should be able to repair in a few minutes. The plywood should run full width of fuselage and @ 2" front to back, a little more if you have a wide bracket. Balsa just doesn't have the strength for lndg gear mtg, especially on a trainer where you are expecting hard landing and more especially on grass fields

I will get some detailed pictures of it. I have already done a little cutting, so it wont' be accurate and i might keep it a trike. I just don't know yet... I did make a ply mount for the landing gear.

Had a question about the wing though. The curveed part of the sheeting on the leading edge broke. And the balsa breaks when i try to resheet this. How shoul i make it work? Some ribs and a piece of ply across? This will be where the rubber mands go so it will need to be strong.

Replace/repair any damaged ribs. Wing sheeting can be made to bend easier if it is wet. Water with a little Ammonia in it, dab it on and try to curve it around, don't try to do it all at once. Bend it a little around and hold in place with rubber bands. Apply a little more water mixture and tighten (or add more) rubber bands. Steam also helps to make it curve better(no ammonia, don't want to breathe) I know you are bending along the correct grain? Be sure to use the orig thickness of balsa. Once sheet has taken it's curve let it dry in place. AFTER dry, glue into place. This all may take a while, again-don't rush

are you using plywood? it kind of looks like indoor paneling your using to redo the bottom of the fuse, If so... and this is just me talking.. you might want to try and get some actual plywood from the hobby shop.. I'm not sure if that stuff looks sturdy enough... but hey.. whatever works... and nice workstation... not sure about the leading edge of your wing though.. that'll be a tough one.. or atleast it would be for me LOL... because of all the stress on the wing at that point... anyway.. good luck on your repairs...

It's Really thin plywood. We got it from lowes instead of the hobbyshop though. You would be amazed at how much cheaper that stuff is at lowes...

The rebiuld is coming along.
Heres what i got done today:
Ply where ladning gear goes glued and landing gear attatched.
Ply where landing gear was glued
Servos remounted in tray
Engine and gas tank back in
Wing about 1/3 done
Some more little things also, I just can't remember. I will not be able to fly this weekend because my instructor can't, but instead i am going to the lake to being the wakeboarding. Hopefully this will not drag me away from RC. lol

Good start on the repairs. It is always best to break the major repairs up into a series of minor repairs. That way, none of them seem as intimidating. As a whole it may look hopeless. Broken down into smaller pieces and you are more than half way thru it already. Lots faster than building a new plane and much cheaper. Many takeoffs and landings will be good to practice. I think your flying will be fine, most accidents occur during T.O. or Landing, especially in full size.

Let me know how that wood works out.
I had my first shock yesterday when I purchased a leading edge and some sheeting at the LHS.
I thought right away that there has to be a cheaper source.

i'm not sure if i'm seeing the pictures right but did you not epoxy the wings together? i see in one of the pictures that the center rib on one wing half is completely clean. although i doubt this caused the accident, it may have somehow contributed to it.

another thing, i'm not sure how the engine was mounted but if the engine mount came loose, make sure you glue that thing on properly and maybe add some more tristock or something to ensure that it doesn't pull free.

otherwise, looks like repairs are coming along fine.

also, if you have dual rates on your plane, i'd suggest that you use one for take offs and landings and the other for "for fun flying". that way you ensure yourself that you're not overcompensating for anything at the most critical times (take off and landing).

Skynard, It is VERY stong. I can't break it with my hand and i have put it threw the tests... Today i will be setting up the reciever and running engine and such.

fore stroke, not epoxy, i used greatplanes would glue, and it didnt work. I will have epoxy this time i will use.

Bruce, I did that yesterday and was VERY surprised on how much i got done. It takes a while but is worth it. I doubt i will work anymore this week, because i have until next weekend

I pretty much have it finished except some small things. I need to make it looks better and whatnot, but the actualy biulding is pretty much done.

Newb there have been several posts urging you to repair the Superstar & keep flying it -- I agree with them. You are enthusiastic, but inexperienced. I suspect that you may be a budding superstar (sorry Hobbico) but ya ain't there yet. Fix it, fly it & keep flying it until you can do everything that it wasn't designed to do, or it is too heavy from repairs to get off the ground. Whatever you do, don't throw it away. I've been flying RC models for most of my life & I still keep a couple of trainers in the stable (modified I'll admit, but they were trainers -- and one of them is/was a Superstar). I'm not bored with them & I'm not ashamed to be seen flying one.

Go ahead & buy the 4*, but keep flying the trainer -- you will be a MUCH better pilot for doing so.

Got to agree with britbrat. I've been flying for 9 years and I still have my trainer. I take it to the field about once a month and fly it just for fun!!!

Hang in there Newb.

Ken and brit brat,
I am very Glad i rebiult. I have no idea why i didnt want to looking back. I don't plan to keep this, but I will probably buy another one, when i get this fourstar biult as wanted

another reason why i am glad is because i have yet to order my 4* waiting on one more check.

Newb,
Great. I understood when you said you didn't want to rebuild, we all go through that same feeling when we crash. But after "cooling down" a few days later I'll start putting it back together. That's why I pushed you when I did. I knew you'd be fine once you started getting it back together.

I'll tell you a little secret. I learned to fly on a Tower Trainer, and I still have it but it's really starting to feel it's age (it's got well over 400 flights on it, and has been recovered twice). I recently bought out somebody who was getting out of the hobby and one of the kits he had was a new tower trainer kit. I'm planning on building that later on this summer so I can retire my first trainer. I want to keep my first trainer for sentimental value. My dad originally bought it and was going to learn to fly on it. He passed away before he could try. I brought it home and learned to fly (both for myself and for my dad's memory) and will keep it as a nice reminder of my dad.

RC KEN,
I plan to display my trainer above my workbench, for the value of being there. But the new one will be on the Flight rack. I have already decided that everyone of my planes will be flyable at any time. It will be expensive, but worth.

I always seem to have one in a slow build stage or in even slower repair mode. Having several "flyable" planes takes the pressure off and you can take the time to do the job right. Right now I have 4 planes I could get into the air if the batteries were charged and another slowly being built(60 size Bridi kaos). Taking my time and doing very minor bash on it. Got plans for next winters project on hand and formulating build process. Big twin with counter rotating 60's.

Just keep on it Newb, you'll be back in the air soon.[
