Increasing portability of the Fling 2M

Based on the enthusiastic comments in this forum, I acquired a Fling 2M. As it will be a traveling plane, I'll definitely use all the hints for a 2 piece wing. Now, how about a removable stab? Can I just use the existing bolts and take the ship apart occasionally for long trips? I'd appreciate any ideas.
Thanks in advance,
Jim Deck

I would remove the bolts from tails. I would remove the tail surfaces and control tubes. I would mold a kevlar tube around the tail boom with releaseable film. The tail tube has length for stab chord plus the fin chord. After cured, take away the new tail tube from the boom. Cut the kevlar tail tube in two pieces, fore for stab and aft for fin. Glue the stab to the fore tail tube. Glue the fin to aft tail tube. Assemble the tail tubes (with tails) with the boom. Align the tails to the wing and tape around the tail tubes to the boom. Glue the control tubes outside of the boom.

Frank West used this tail mounting design about two decades ago. It works.

Frank's tail mounting design disassembled it's self very nicely when he had a midair at the 93 LSF tournament. Frank had a difficult time finding his model in the 10 ft high corn field while the other model landed back on the Lawrenceville airport.

It's not real pretty up close, but here is the Kevlar mod I made to my sons Fling 2M yesterday. A little Tow goes a long way...

Does anyone have a picture of this set up?

Thanks in advance.

Fling 2M's I am told, have snapped the tail group off on landings that were a little rough towards the rear. The problem is there are 2 major cuts at the rear of the pod boom for rudder and elevator exit points. Kevlar tow wrapped around these areas will help to reduce the tail group from snapping at these cut outs.

Those must be extremely rough landings to snap the tail boom. I've never had a problem with mine. I also saw another Fling 2M hit a fence with its tail pretty hard (the strong slope wind and the turbulence at the ridge blew it right into the fence) but there was absolutely no damage.

Same applies to my little Fling (not the DLG) - it has hit the ground and the fence on many occasions without any damage to the boom although I had some slight wing damage on a couple of occasions as.

Never have flown a Fling, this was just a mod that came as a recomendation...you only bust it once, maybe I can deter that demon with this mod.

What I did... Wrapped boom with some kind of thread(don't remember), added glass with epoxy under the screws to keep metal from contacing the carbon and distribute load.

I also wrapped the spar, just like Johnnie, plus, I omitted the tail skeg. That left a hollow carbon slot in the boom, (rather large), so I filled it with balsa, CA'd it, and wrapped it with kevlar too.

Battery pack for Fling 2M

I have my Fling 2M nearly ready to go. I notice that none of my flat receiver packs will fit. Now, I don't wish to build my own pack so what commercial packs can you recommend? I see Great Planes has one under its Electrifly label that's recommended in the instructions.

For my Fling I went to Batteries Plus and got them to make up a AAA square 4 pack of 850 mah Nimh cells while I waited. I supplied the leads and connector and it took about 10 minutes. Perfect fit in the nose of the Fling. I'm sure Radio Shack would do the same.

I'm using a similar pack, which I made myself. It fits perfectly in the nose just behind the 1oz. lead that my Fling 2M needed to balance properly.

Anyone know what brand film the Flings are covered in?
How did you exit the control linkage thru the fuse when placed on the outside of the boom?...Pictures?
