now that is a nice location


and good weather, and action-packed air-to-air filming, too!

nice video, transient, it's great to see the planes from the perspective of another plane.

amazing what the keycam can do!

I am rapidly coming to the conclusion that cameras on planes are bad luck magnets. The last three flights with cameras on board have ended in disaster - Two planes destroyed and one ESC failure that I managed to recover from because it was my TwinStar and so I still had power to the control surfaces. It is on the bench waiting for its new ESC right now.

can someone tell me, will this battery (228 x 69 x 34.5mm) fit into twinstar?
if yes, then will it fly with 1021 grams of weight?

Even if you'd physically get it in, you would need additional ballast at the tail the get the CG right. As you would almost double the design weight of the model, it would fly like a brick compared to a light TS II - so what are you trying to achieve?

You could carry it suspended on a strand of creeper between two Twinstars?

You won't get any long distance flight.... Your motors would swell at full throttle during a couple of minutes trying to keep you TS airborn.... Go with 3300 mah 3s lipo max and you'll be a happy camper, I fly mine with 2200-2500 ones.

thats a monsterous battery! I use a 3s 4000mah Flightmax 20C and get 20~25minute mixed throttle flights at an AUW of 3.6lbs.

if you could buy a high-end motor+esc combo, what would you put on twinstar?

as i see, most of the people flying on 3s, around 1500kv motor and around 20A esc
but what if i'd like to fly faster and higher
i found this esc for example:
http://www.hobbycity.com/hobbyking/s...dProduct=11430
40A and up to 6s
is this a good esc? will it fit into twinstar?
what motors to choose which will fit into this plane and will hold such huge amperage and voltage?

maybe someone can give me some links (within this thread maybe) to a "powerful" twinstars?
does anyone tried to fly on 4s-5s-6s? i wonder how fast is that? and how high can it fly?

what's the freakin' point, would be my question. on stock brushed motors, props, etc. the twinstar 2 is actually pretty quick. upgrades accomplish other things, not speed or altitude records. if you want to fly higher and faster why not a glider? but hey, if you want to take a v8 and drop it into a yugo, be my guest.

You can fly a stock TS II to a height where you lose visual contact, but what's the point in that?

nevermind what for
with camera on board there is a point to fly high and fast.
not all the time of course, but sometimes, for fun, why not?
i just curious did someone tried this or not?

If you want to fly "high" and "fast" here is an alternative...you can see this at 1500', it has a built in HD camera, FMA co-pilot and it is very fast.

World's first* Twin Motor Easy Glider Pro (6 min 28 sec)
