Good weather has allowed me to fly my 260 lately. I tried a knife edge snap and the prop decided to go on ahead without the plane. Fortunately, this bird is light enough that I was able to "dead stick" it in with out any trouble. 1 o-ring to retain the prop is not enough. I'll have to find a replacement o-ring and put 2 on.

I flew my extra 260 for the first time today and it was awesome. This is my first 3D plane and it was a blast. Though when I tried to do some hovers that I practiced on the simulator it felt like i didnt have enough rudder. I think i might not have the dual rates on the rudder....any one know how to fix that? Other than that it was great!

My park 300 motor burned up after I reversed the shaft.

I'm looking for a replacement moter. What is a good motor to run on this little foamy??

Just flew mine outside with 300, 18 amp and 640 battery.
1st flight was nose heavy and some struts let go.Second flight was quite fun,but more struts let go and it flexes alot.I will wrap the joints with thread and reglue.It flys OK,but I will need more time with it.It felt heavy,but flew quite slow and predictable.Hovers are easy,but not a huge amount of pullout with my weight.My batts are also getting old.More details,next time out

wrapped some thread around the some CF joints,mainly the 4 that attach to fuse and wings and some near the back fuse.I gave it a good workout and made some rather harsh turns and incredibly tight loops.It held together and flew pretty good actually.Seems to excell at Harrier flight.

I just got a TP 3cell 370mah lipo for my extra 260 and I was wondering how you go about balancing it. It is the only Lipo I have so far that doesnt have a balancing lead on the end of it.

are any of you guys having a problem with your plane just fluttering when it flies. When I first built mine and flew it a couple times, It flew nice and solid, but lately it seems like something must be getting looser on it because the left wing will start to flutter real bad and it and the plane will just start to jump all around for no reason. I looked at it pretty good and the struts are not loose, they are still attached to all the end points where they are supposed to be, but some of them flex a little more than others. I think that is what might be causeing my problems.

Huh, you guys sound like you need a power alternative. I have used a Rimfire motor on my Riot, and it still has the power to pull the 10.6 oz. plane vertically, but not too fast. The little 28-22-1380 runs slightly hot, but it has proved a worker for 35+ flights!

Hey davidgeorge, did you look at how tight your controll surfaces were to the plane, and how tight the linkages are? I had this problem before, and it seemed to go away when I tightened them down.

And from the sounds of things, it looks like I've found a new plane to get, to replace my knife edge coupling happy Riot. How does it KE, and torque roll?

davidgeorge212 - It may be worthwhile to check the glue that holds the servos in place. I had issues with hot melt glue not holding well and re-glued with CA.

lilbanchee - do you by chance know how much the Rimfire weighs? This little foamy torque rolls and harriers awsome! I have some coupling with knife edge but I think that I just need to program it out.

You know, I checked the servos they are stuck in there, I put them in with thick foam CA. I also looked at the pushrods to the control surfaces and they are jiggling around or anything but its not like totaly stiff where you cant move it. Especially the elevator and Rudder pushrods flex a little but they are not jiggly loose.

I have S75 in the wings.Mine will flutter too,when its windy or if i get going to fast.I actualy have gear slop in them now.I think kits important not to race around in this Extra.The ailerons are very large.

yes yes and yes,its a complete waste of time.This is the profile body thread.. stick in their 480 size,should work fine.Not sure about 81's,probably overkill and heavier.use HS55 or E flite S 75.They seem to hold up on mine and are light.Every gram counts if you want top performance.

I see many complaints of flutter or buzz.... In this instance, the tail can wag the dog. That is the elevator loading and unloading the wings. You may want to, as an experiment, fold some clay or light weight over the outboard elevator leading edges to obtain a nose heavy control surface. This will bring convergent the oscillations.

Interesting.I wonder if the indoor guys have flutter too(on this plane).
Flying outside can easily lead to much more airspeed

I am the world's worst at over beefing aircraft. That said, I used some one inch aluminum tape folded over the outboard leading edges of the evevators. This may be enough to get the control surface leading edge heavy forward of the hinge line.
I see this problem on a regular basis with the full size aircraft usually over 300 KTS. If the ship endures the flutter for any length of time, we find that it causes premature wear on all control linkages and bearings. The wear and slop increases untill the crew feels it, sometimes in a violent manner. Scale the issue down to model size and surface material and it all seems to fit the situation as well.

Yes ,flutter brings RC aircraft down on a regular basis,especially when you get into the 50 inch and up size.

Im not sure if this thread is dead or not but ive just decided to get one of these to have a bit of fun with round the house when i cant get out to the field. this is my first electric plane so im not sure what battery i need, ill be using the park370 (cant get the 300 here) and s60 servos. Im lookin at round 7-9mins of flight time ideally (intense 3d flight). Any suggestions on which battery i should be looking at? Cheers.

Some recent experience with the 260...

Built per instructions way too heavy. OK, strong, but too fast for close indoor. OK outside up to 5 mph winds. Will mid air anything and keep flying. AMHIK.

My setup (second time around)...6.5 oz all up....

Lose two servos..use one on ail, one on elev, forget rudder..not needed even for very tight indoor flight. Just use ail on high rates...very effective, most observers won't even know. Lose l/g, hand launch. No extra carbon rods..use spectra fishing line..not as stiff especially torsion but really OK in the air. Its a stiff plane to begin with.

Motor...Eflite 250 (plenty..300 is overkill at this weight) , carbon rod mount, APC 8/3.8 slow fli. Pack..I'm using 2S 900mah..heavy but flies all day. Weight savings possible here.

Balance...slightly tail heavy...goal is level to climbing rolls at 1/3 to mid throttle. will almost knife edge using a heavy tail alone.

Lose the weight ( be creative, out of the box) and its a totally different plane. I have one at 10 oz...great park flyer, the 6.5 oz..much slower, but will still fly out of a midair. He he.

Flying this plane currently, flys well even tho mine has come out overweight according to the makers specs. Managed to find a eflite 300 so ima swap out my 370 and 850mah battery and go with a 400mah 2s. Hoping this will bring my AUW to 200grams. Still even in its current configuration it seems to fly well, they sure do awesome torque rolls.

I have the Eflite 300 outrunner, futaba S3114 Micro HT Servos (four), a futaba R607FS 6-ch Receiver with the 2.4GHz FASST system, and both thunderpower 480 mah 3 cell and Common Sense 800 mah 3 cell batteries. The plane is great. I have one 2 cell common sense 800 mah battery which does not have enough voltage to hover continuously. You need 11.1 volts to hover at 2/3rds power and maintain altitude or climb out of the hover. My main problem was carbon fiber strengtheners letting go. The wing or fusalage struts would separate then the wing would start to flutter a bit. I would land, glue it with CA, fly a few more flights, then glue it again. I then put a bit of hot melt glue on the joints over the CA and the plane holds together great now. I have 50 flights on it and just ordered another for when this one is totalled. Yesterday, I was hovering and drifted between a bunch of basket ball hoops. In pulling out of the hover I misjudged and clobbered a basketball hoop at full throttle, the plane fell to the groud and then flew four more flights before I fixed the wing damage at the end of the session with a bit of tape and CA. Great plane to learn 3D with.
