NEXSTAR ARF .....PROBLEMS...PROBLEMS
#51

If you remove the wing "gadgets" be careful on the first takeoff as there may be a significant trim change. It will try to pitch up on you if I recall correctly, be prepared.

Hey Wheels see you are in Ind. I was born in Logansport. I use my flaps to get up quick which also helps in staying straight, quicker you get up the better control you have in my opinion, I had a heck of a day today, after changing the wing to be flater I had also mixed ch 1 & 5 for flaperons, what a mistake that was, never could get it trimmed out correctly so went back to a y on one ch. I was up about to 2 hundred feet but on the flaperons and she droped like a rock, geezee I had to change shorts, got the ole heart to racing. Anyway she flies great now. Yes I still have on the anti-spin-stall devices. Also had to change rate of airleons, she was way to touchy, but I am happy now. Today at field.

Hawg -- it looks looks you kept the plastic center-section -- is that correct? I always ditch it because it is shaped for the dihedral wing. Any problems joining the wing with the plastic piece?

Naw man I cut the plastic rib piece out and made the thing flat inside so I would have no seam and the bolt hole plus the dowel in front, plus someday I want to us it to attach a camera to the top of the wing.
The only problem I had was that darn bar getting it right, I figured you might notice the wings seem to droop a little in pictures. I got a little glue under one side of the plastic piece oozed out but will fix that today. I just love it this way.

When you get used to it, that little bit of anhedral will help with your aerobatics, but it will make the low speed handling a hair touchy. If it is a real problem to you, fix it, but I wouldnt bother -- you'll get used to it.
When you get rid of the droops & speed brakes, then crank up the throws, you won't believe how that plane will fly.

Winghawg if you ended up with a little anhedral (droop) by some mistake and have been flying it OK then may I suggest you leave it in. With any High wing cabin type when the so called self righting of dihedral may no longer be needed then anhedral will impart a more 'stays where you put it' type of flight that is so highly sought after. For that type of neautral roll stability a totally flat wing is desirable only on a mid wing airplane, a highwing airplane a little anhedral is best and a low wing airplane will need a slight dihedral.
I,ve bashed a few trainers this way for others and the results are always very pleasing. Look at it this way you could call it 'Dumbo Hawg' [8D]

'Dumbo Hawg'
Okay I guess thats not an insult being called 'Dumbo Hawg' sounds almost cute. It flies really well and still has great slow landings. I am only going to remove some glue from under the plastic rib cover. I love the plane. I had trouble trimming her yesterday and went back to 2 servos on ch 1 then she trim out good and I had to much throw in the wing servos and she was really flipin around but thats fixed and we are now getting along great. Now I need to get the wrinkles out, if heat takes them out then why do wrinkles form out side in the heat? I need some small decals saying her name. "Dumbo Hawg"
wait tell my wife hears this.
Oh yeah and thanks for all the great compliments thats something I have really needed here lately.
Tail Draggers rule.

Absolutely Winghawg1 certainly no insult intended and I like your landing gear 'bash' (bashing is a complimentary word meaning the airplane hase been modified to personalize to the builders desire) of the main gear. That is a bit difficult to do on that airplane.

I read thru these post quickly, the problem with the nexstar pulling to the right is quite simple. I have had mine for over a year and corrected the problem with shims, the motor is set a @ 4 degrees right thrust. About the thickness of 2 popsicle sticks behind the motor mount on the right side. Then pitch the extensions and the flaps. With the flaps off adjust the elavator clevis about 8 turns out to compensate for removal of flaps. Nothing wrong with gear unless they have been bent on hard landings. Also you might as well replace the fuel tank it will eventually split at the neck, so far everyone I have talked has to replace the tank. Mine is on its 4th student.......

Like I told Britbat I carved out the piece that holds the wing with the four screws which made it flat and used it to cover the wing seams, be careful doing this the plastic is tough and hard to cut but I did it and came out with it flat but in 2 pieces, I then added some extra screws to hold it in place and then redrilled the bolt hole at the rear and had to cut the dowle pin hole a little higher to get the wing to seat flat on the plane, also you must bend the metal bar just right then test fit before glueing the wing halves and attaching the plastic support piece. Maybe this pic will help some Also mounted to servos side by side in the middle using a y reverser for the flaps. The pic is blury when blown up but you can see the joiner is flat. Also notice the 4 screws on top had to be reinfored in the wing before glueing, I used 2 short pieces of flat squared hard wood dowels the I got from the craft deptment at wally world.

Winghog.....a fellow Hoosier !!!!! Kokomo here.
Flew again today and the take offs are much better now. My landings are really getting pretty good as well. Today was quite windy
and as my instructor said...."you need to learn in windy conditions as well " and I did just fine.....in fact.....kinda a rush with a little
hairy crosswind....was really fun.
I am now feeling like "I" am flying the plane much more-so now....instead of "IT" flying me.
I think the biggest improvement was installing 5 1/2" tires......seem to really help on grass field

First thing I did after flying mine the first time was change the wheels but I have 3.5 on mine. How do you like the looks of mine as a tail dragger and the flat wing? Damn she fly's nice. John named her "Dumbo Hawg". Won't tell you what my wife said about name. Look back a few posts. Here where we live if you don't fly in windy conditions you will never fly. When I started I would sit and hope the wind would die down to at least 15mph about all the other guys were flying and finally Billy said " If you ain't gonna fly the damn plane take it home." So wind doesn't bother me.

Winghawg......I like the taildragger look......looks good
As for feeling "better" about the plane......well.......I had a long talk with it.......so far......seemed to have helped...... we'll see.

My friend and I both have NexStar trainers and both planes pull to the right as soon as they are in the air.

The fix is to reduce the right thrust on the engine by inserting thin flat washers under the right-side screw that affix the engine mount to the firewall (you can also use a popsicle stick, or make a ply wedge).
The built-in right-thrust is correct for 1/3 - 1/2 throttle cruising, but is excessive for full power operation (like take-off). The Nexstar flies perfectly well with no right thrust at all.

I purchased a NEXSTAR rtf. This is my first glow plane and I wouldn't know what to suggest on your problems, but I can tell you of my experiences (so far) with my NEXSTAR. On the first flight, the landing gear fell off at about 400 ft. We never found it. I ordered a replacement set and soon discovered the replacement also never stayed in, even though they seemed to be locked in. My instructor suggested epoxy-ing the gear in place, but I used the epoxy sparingly and they didn't hold. On a rough landing (by my instructor) the landing gear must have popped loose from the mounts and trashed the fuse's belly under the mounts. My instructor could not believe how much damage was done. The landing was not THAT hard! I have not yet got together with my instructor since I repaired the plane. I am afraid that it may be too heavy to fly properly, but I fixed it the way I was told by my instructor.
My NEXSTAR flew great( according to my instructor) and the landing gear has been my main problem. Other problems were almost all the motor mount screws came loose, the motor would not idle until about 5 tanks of fuel ran through it, and the fuel tank had to be wrapped in foam to keep the viabrations down( causing the fuel to bubble).
I have not yet had enough flying experience to take off or land, but I am getting a lot of experience on repairs.

rincloud was reading your post sounds like you need to file out the landing gear holes sometimes they get filled with paint or aren't drilled properly dont epoxy them in as you will have problems bending them back when you land hard" you will eventually land hard"my nextar has had some trials as mentioned in this post. but so far and after a rebuild after some (pilot error)flys solid." its about you flying your plane " if you dont have to adjust to some issues you are flying a kite as posted the front gear does have some issues. have your best engine guy at your club tune your engine sounds like she's running to rich factory settings foam the fuel rich sometimes do vibrate a bit. the nextar is a durable plane get your speed up and ease her into the sky good luck.BT
