That was awsome... How did you do it? Could you post some pictures of the camera setup in your plane?

TS-2 is a very nice airplane, I really like it, easy to fly, and how easy is it to fly? Well, I can't tell much, compare it to a 3D, F5B, Pylon, Scale war bird, it is 'easy' to fly.

When I fly I'm using my left thumb (rudder) most of the time! to coordinate turns.

here are 2 more videos, with less aerial stuff where you can see how this plane flies...

pd/ the first video starts with the same intro taking off from the snow from the cockpit, check them out!

Enjoy.

Hey Derick. I just got my TwinStar yesterday. Looks like a nice kit. I'm wondering... did you do anything special during the build? I noticed in your videos that yours is 40.1oz. The instructions state an AUW of 50oz. I was just wondering if you used carbon fiber or anything else fancy during your build. I want to keep mine as light as possible since this is going to be my AP rig.

Also, another question.... The instructions say you can't use epoxy on this Elapor foam, and to use medium CA glue with kicker. But it didn't say if this is supposed to be "foam safe" CA or not. I'm assuming since they did not specifically state foam safe, that normal CA works ok, but I wasn't 100% sure about that. Will normal CA work?

Thanks!

Nothing special, but I did use a 2s 4400 Lipo (less than 10oz.) instead of a big sub C cell. that brings the weight down. I did use some strapping tape at the bottom of the fuselage.

I did AP with my first TS and AUW was 56oz. so don't worry too much about how much it weights, for windy days I like it heavy.

Regular CA works! thing and medium / kicker.

Cool. Thanks for the info. I was looking at that big wing joiner/spar and thinking it was pretty heavy. Do you know what material it is? I don't think it's carbon fiber. Graphite something-or-other maybe. :) I've got a single 2S 2100 lipo to go in it for now. If I like the performance, I may get a second pack for 2P 4200.

2s 2100 is not heavy enough to balance your TW2 you may need to add weight in the nose. Also be aware that you will be pushing the limits of your battery; 2 speed 400 motors will easy do 20 amps.

Hmm. Thanks for the heads up. I wasn't sure what the stock motors pulled as far as amps. But I was planning on checking it with my Watt meter. I may have to stick another 2100 pack in there then.

Oh, I also noticed in the directions it says not to cut the ailerons out. It does not use hinges. Does it seem to work ok like that? It had me worried because it did not sound like a great solution to have the foam bend along the hinge line as the actual "hinge".

How does it fly with that camera attached? I had a camera attached at the cockpit area that acted like a wind scoop (probably similar to yours), and it flew like crap! The camera totally screwed up the aerodynamics.

I can't even tell the difference. Flying low, slow or fast. I even like it better because the extra weight the inertia helps a little bit covering airspace and a more solid pattern flight.

Make sure that the CG stays the same! very important!!! ;)

04-05-2006, 05:20 PM
Yeah, I move my battery around to keep the CG the same. Maybe I'm flying with the CG in the wrong place to begin with though. Where do you have yours set?

After reading your thread I decided to purchase the TwinStar 2 from hobby lobby during their 20% Christmas special. It's plenty big enough and can carry a lot of cameras with just the stock setup. However, I did upgrade a little buy purchasing two 400 7.2 motors instead of using 400 6v motors it comes with. I did this so I can use my 3cell lipo 2100 pack that came with my f27c Stryker. I believe the 30 amp jeti escape will have no problems handling that setup. If you think not please let me know!!! I plan on using the stock propellers and buying a different extra set. Iím not sure of what size I should get though. Iíve been going back and forth between planes for what feels like a month now. I canít wait until it comes in. Iím sure Iíll have some more questions for you guys since Iím a total newb when it comes to building planes.

Derick, or anyone for that matter sees a problem with my setup please let me know!

Thanks,

If you want the Ballistic setup, then check this out. I've been working on my TwinStar. Making it into an aerial video platform for FPV (First Person View) flying. It was clear that the stock motor setup just wasn't going to cut it. When flown fast (like in a dive), it really flew straight. So what was the cure?? More Power!! I went with two 400F brushless motors, two Thunderbird 18 ESC's, 6x4 props, and two 3 cell 2100 Thunder Power packs in parallel. The result was absolutely amazing. It totally transformed the way the plane flew. It can fly super fast now. Do really nice rolls (for such a big high wing plane). And can we say unlimited vertical?!?! :D :D Yet it still weighs about the same as before. The lipo packs are heavier now (6 total cells instead of 4). But the motors are lighter. In the end it may be just slightly heavier. But I'm still hanging around 42-43 oz. which is well below the manufacturers specs. for the plane. Very soon I will have the video setup complete and installed. I will have to get some video of the plane, both aerial and ground based. You just gota see this big elephant fly! :D

KyBrowns:
I think your set up will be fine for a conservative flight envelope and ca$h, I still fly mine with the stock motors. Now if you like MORE power doing what twinturbostan has done it's a good set up too.

You can use the stock props they work great.

The sky is the limit:)

p.s.Derick great videos!! By the way I have a Sony Cyber shot also. Can't wait to get in the Twin. I See that you fly a Wingo also. What do you prefer flying in general and what do you prefer flying for AP? I almost bought the Wingo instead of the TwinStar.

Derick Veliz
12-28-2006, 02:56 PM
2 batteries running in parallel (2 x 3s-2100) it's like a big 3s-4200, doubles the capacity of the battery.

For AP I use:
1.- Wingo %90
2.- Slow Stick %4
3.- Easy Star %4
4.- Twinstar %1 better for aerial video
5.- Eco 8 heli %1

Depending on the target and weather conditions each plane has its charm. Been the Wingo my favorite.

Thank you,
For AP, a Wingo/Slow Stick are much better than a TS (they need less area to take off and land, also they are more stable hands off), for FUN/Aerial Video the TS-2 its awesome, flies like a real airplane (M,R,E,A).

We as a family are doing great, not a lot of sleep but very happy:

I've been flying the TS2 for about a year. I've got 2 cheap "bell" type outrunner brushless which go pretty fast. They only cost ~ $33 each as a ESC/motor combo, so two is still cheap. The ESCs fit behind the motors in the wing nacelles (good air cooling!) and the ESCs are controlled by a Y lead from the receiver feeding extension leads to each ESC. I didn't bother initially cutting one of the red leads and it worked fine. I then read in QEFI that you should - it still works fine!!
I have some video to upload. I would say the TS2 is a bit too "lively" for a stable AP platform, so I'm investigating an own design instead.

Hi all,
I've been using SlowStick/Wingo-type planes for the duration of my budding AP "career". However, I recognize the need for a plane that can really get "up there" over wide spaces for those landscaping/farmland shots, and the EasyStar seems the perfect choice.
In other words it's time to add a bigger AP plane to my stable.
A question: I've been somewhat puzzled about which brushless motor system to stick in it. All my AP planes use outrunners, and I'm baffled about how one picks a motor for the EasyStar. It's stock prop is only 5 inches, so that confuses me even more - will I need to use an inrunner with a direct drive? Or an outrunner?
How are your personal EasyStars set up for AP use?
Thanks in advance for helping an "ijitt!"

Derick,

Very nice work indeed!! I'm just starting to look into AP. Thanks for posting the videos. The TS looks like a real nice flying plane. I happen to have a brushed 35 AMP ESC without a home, I may have to pick one of these up. I also like how you and take off from the ground without LG in the snow. Will it do hat off of grass too?

I liked the turns you did down low to the ground, very tight. That rudder must be pretty effective.

I am looking to build the Twinstar II soon.. I've read around and did research on this, but wanted to see if anyone could comment on my choices for motor/esc/battery.. I will eventually add a rangevideo 900mhz camera setup to the plane with another lipo pack, totally around 4 OZ in weight..

My goal was to get a larger boost in takeoff climbing .. and power overall, by converting it to brushless..

Can anyone tell if these choices are good or something better?

Bp-21 was my original choice for motor, $13, 1400 KV, 1.77oz, 13 amp max draw.. http://www.bphobbies.com/view.asp?id=A1190097&pid=U422859 with 8x4 prop

Now i'm leaning towards BP-12 , $13, 1000 KV, 2.26oz, 12 amp max draw http://www.bphobbies.com/view.asp?id=A1190097&pid=U635171 with 8x4.3 prop, as this one some have said would hault AP equipment up faster?

For the ESC for the bp-12 (and maybe bp-21) I was going with Castle 18 amp thunderbird.

For the battery in all cases.. I was going with a DN 2150mah 3s1p 15C lipo ($79 for 2: http://www.xushobby.com/servlet/Categories?category=Li-poly+Battery%3ADN+Power+15C+Continuous (http://www.xushobby.com/servlet/Categories?category=Li-poly+Battery%3ADN+Power+15C+Continuous) ) with a thunderbird charger (the thunderbird equivalent battery is nearly 2x as much for one)
