Soem people have converted the older Twin-Star into a water plane. The standard fuselage however neither has got the right "volume" nor the correct shape for a water plane. The guy made some kind of a "styro shoe" where he put the fuselage into.

Some people have also put the Twin-Star on floats.

The Multiplex CARGO looks great on floats. Here is a video clip:

First flights with the new spinner/prop combination - and this time I made sure that the camera view was not obstructed by strapping tape.

Tech Info: The 6.6x3" Cam Slim Prop is too big for the Permax 400, 6V. Even on 7 cells, static current per motor is about 15A@13.200 rpm. With a 2s1p KOKAM 3200 they are probably perfect - despite being quite heavy at 12.5g each (with spinner).

Jurgen, are you going to keep them and use the lipos or re-prop? They certainly LOOK nice, tt.

Jurgen, thanks for your excellent review. One thing I'd like to ask you is how you would make the aileron servos replaceable. I mean the servo leads cannot be reached anymore once in the wing groove and under the spar covers. Is there room enough in the aileron servo recess area to house the lead that comes with the servo and its plug connected to the plug of an extention that would itself then run under the spar cover, same as could be done on the TwinStar I ? (Which in short means the connection would remain apparent and accessible). I plan to fly my TS II with two Permax 480 and very possibly those mean-looking precision spinners you so aptly adopted. Packs will be 8/2200 GP NiMh (arranged in two parallel rows of four) that are so compact and light. Thanks in advance for your comments on all this.

I will keep them when I use Lipos, but most likely I will replace the motors too (Permax 480, 7.2V instead of Permax 400, 6.0V). The increase in torque should get the amps down.

If you look here:

http://www.rcgroups.com/forums/showp...3&postcount=19

you can see that I cut the servo cable rather short at the servo and soldered the extension cable in between. If a servo fails, I can - provided no glue got to the extension cable - pull the cable out a couple of inches and solder a new servo to the extension cable.

8/GP2200 are fine, but rather expensive. Being NiMH they probably don't like multiple charges at the same day. A 2s1p KOKAM 3200 doesn't cost that much more, has more capacity and weighs only half.

So can 520gr be considered the empty weight for the Twinstar II or is there anything missing in the list (glue weight, decalc )?

Perhaps somebody has the weights of the "old" Twin-Star (for comparison)?

Glue and decals are not counted for, but then I have not subtracted the bits of the control rods which you cut off either.

Building!

Just about to glue the two hlves together! Waiting for the kicker to dy!

I've run in the two Speed400's using David Hippersons technique - dunk them in water the a drop of dish washing liquid while running for 90 seconds or so then dry them and put in clean water to rinse for 30 seconds!

Back to the bench!

Cheers
