Sparky, did you just reshrink the covering? Was the defect built in? How bad were the turns.
On the brink of buying one...JS

I reshrunk the covering. But it needs more, on both wings. The weather is getting hotter, and the covering is loosening with the heat.
I would buy another one anyway. It's a good wing, with the rest of the airplane quite good also.

I made mine two piece by simply not gluing the 2 halves together and adding a locating pin near the trailing edge...Sanded the joiner so it was a snug fit and I tape them together before flight with electrical tape and have not had a failure yet doing loops at my local slope .YMMV

I have had other 2M ARFs that I built the wing as a two piece. They have been very successful as EP gliders. (Not as much stress on the wing with EP launches.)

I think it is important to insure the joiner is a snug fit in both joiner boxes. I build up the joiner with balsa to insure no movement is possible as required. I then epoxy one end of the joiner into one wing half. You can't loose/forget the joiner that way and it is definitely a tight fit on that end. I also make a locating pin as mentioned above.

I then use tape to hold the wing together during flight.

I would not epoxy the joiner in if it were mine. If you ever break the joiner you won’t be able to get the one half out. I have used Goop to hold the joiner in one half and then been able to extract it at a later time. One other hint is to make a second joiner now so you have an exact extra to work from if it breaks. The Spirit ARF has a notorious week joiner and on that plane (and maybe this plane) it will make life much easier if you do a little extra work/planning now.

Just my .02

Among my planes I have two Spirit 2Ms and both have 2 piece wings. One launchs from a 3M strength hi-start. This is at my Parent's house.

The other also lanuchs from a very strong hi-start AND a 12V winch. I tape the wing before flying, then pull or cut the tape at the end of the day for easy transport. Works fine!

Well I went and took the plunge.... One fling 2M in NIB on my living room floor. During the build I'm gonna take some steps to sure up the boom though. Maybe glueing the fin to the stab and inserting the pins though some glass and epoxy on both sides of the boom will help destribute the load of those washers and bolts on the bottom. I just can't see myself tightening down any metal directly to carbon as designed. Next I'll steal some left-over carbon from my DL50 kit and do some wraps in front of the tail just for good measure.

My tail has remained tight since I assembled it 3 weeks ago held on with the stock configuration....what I did do though was wrap carbon fiber tow (anything will work really....cotton thread..kevlar thread ..) around the boom wherever it was cut for pushrod exits...front and back as some were complaining about the boom splitting back there ...and thin ca'd it in place ...

Time may loosen up that connection since the fin studs pass through wood but for now I'll leave it as is...

Yes Mike, I just had to get something I could histart in the air fast. Add to that the fact that I just got $100 bucks for a graduation present and I just couldn't tell myself no.

Now don't you go and get a 2M Chrysalis up in the air first!... Just kidding.
We gotta try this thing out before the week is over.. I'll check the forecast and let you know.

How much ballast

Following this persons lead, I added a couple OZ of hammered and drilled fishing weights to the cg of my purple fling, and it is a completely different plane (in a good way).
http://www.rcuniverse.com/forum/fb.asp?m=3050151


Has anyone experimented with their fling 2m enough to make some flatland ballast reccomendations for different wind conditions?

Thanks,
Skewbe.

Fling 2M Wing Mounting . . .

Has anyone modified the Fling 2M from the wing dowels and rubber bands to a wing bolt system? It seems it would be much more aerodynamic and aesthetically pleasing. If you have please advise as to how you did it, and the performance since the mod.

Thanks, Randy . . . . .

how does this thing do on the slope? I am looking for a second plane to fly if I go to my local slope and the wind is not pumping hard!

If you have good landing area, the fling would probably be good for light lift. Most light wing loading thermal planes are good for light slope lift.
