Urgent,best Lipo Batteries For Movie Star Multiplex
Hello to everyone.
To day i have done my first fly with my new MOVIE STAR without any pay loading.
I use multiplex permax 400 motors reducted .i have used a lipo 11,1 v 1500 mah.
Do you think that it is better to use a 7,4 lipo 2000 or a 11,1 lipo 2000 0r 3000 batteries.
Also the with the reducted it seems a bit noisy.

See http://home.online.no/~la9ex/MovieStar/moviestar.htm for some pics.
See also http://www.gpsflight.com/GPSF/Users/moviestar.htm
See http://plawner.net/4/moviestar/per_tidemann/ for a brushless setup.
See http://www.multiplex-rc.de/ for the manufacturer.
There are also one or more threads in RcGroups about the MovieStar, only one of which ended on a more positive note after upgrading to two brushless motors.
I also have one and so far haven't been too happy. It's big and heavy. If you want to turn sharply at low altitude shortly after takeoff you might want to sent your camera to the Macro picture position... (luckilly I didn't have a camera in it tht time). It comes with two Speed 400 standard. I have upgraded with two gearboxes, but still find it less than optimally powered. And of course the gearboxes are a bit noisy. So far I-ve only flown on a 8.4V 1700mAh NiCad battery pack (400 grams!). I intend to upgrade this to LiPo's (11.1V 1200mAh 2 in parallel = 2400mAh at 165 grams). One of the above links is actually flying with about 4Amps of LiPo's and two brushless.
The aluminium tailboom on mine came loose twice during flights despite CA-ing and later epoxying it into the fuselage. Bit difficult to control if elevator actions just pull the whole tail in and out of the fuselage but not much more. I-ve now resorted to using polyuerthane glue (which should work Ok as the foam used is actually also polyurethane based).
I-ve already decided to go for a Depron / Fanfold RcGroups or own design for aerial photography. Should be possible to build something with a roughly similar span but at about half the weight of the MovieStar (and thus with a lot more carrying capacity if you do want to load it up). Actually, I-m thinking about modeling the ARES mars-plane () for that purpose.
