And yes, one of the nicest TS II so far !! Really good work !!!

Hey! Pat

Thanks for the compliments. BTW i have not been able to get this bird to ROG except hand launch so far. Not even when i tried running 3S1P 2100mAh lipo at 80% throttle drawing 24Amps. Find this really strange.

Is there anything that i did not do right? As i mentioned, i might want to try using other prop size to see the effect.

Do you have any views on using 3 blade props? I am thinking of trying.

In what way? Does it simply not reach flying speed? What surface is this on? Are the wheels out of alignment, or binding? Are your wheels a long way forward of the CG (hard to tell in the pics), which would make it hard to raise the tail?

My trike gear TS1 would ROG from soccer pitch grass with direct drive S400s and 8 cells, but acceleration was fairly slow.

Hmmm, i will give it a try again this weekend to check out the details, will provide more details after this weekend. Thanks for all the pointers to look out for.

A hobby store in Madrid has recommended the following battery for the TS II:

BP4600 7,4 (2S) 38x38x105 mm 235 gr. price: 87,50 Euro

They explained that they call it 4600 but the pack contains two 2300mAh cells in parallel “internally”. I am not sure if I have understood what they mean with internally, is it an ordinary 2300 2S2P?

Do you think its too wide for the battery compartment? Would it be possible to widen the compartment with some millimetres?

The width of the battery compartment is 28mm. It should be fairly easy to remove the 5mm per side if this is done before joining the two halves.

Hello, or to buy the the least expensive twinstar II with batery, variator, receptor in 40mhz?

thank you

And it flies really very well, except when climbing altitude during launch. Once it foes up in the air, it flies extremely well doing flips, rolls, inverted, spiral etc.....

Instead of changing motors, i would like to fly the bird with other props, and the props i have in mind are;

1) 5 x 4
2) 5 x 4.5
3) 6 x 4

am even thinking of using 2 x 3 blade propellers, i wonder how the huge plane would react with 3 blades propellers ;-) Can anyone advise if they have tried 3 blade propellers?

Attached is my TwinStar II.

I fly my TS2 on Speed 400 7,2V - 11,1V 2100 LiPo Battery - Jeti 45 ESC.

I tried some props:

5x4 : the white stock GUNTHER prop (4,9 x 4,3)
Good in almost all case ... but they break easily (and start the big noise). I use them ... but I search some more trust.

6 x 4: the red GUNTHER prop (5,9 x 4,3). too much trust .... also at low RPM ... a lot of amperes and very hot motors. Used just one time at very low RPM and battery discharged very quick.

5,5 x 4,5 : by APC; a great delusion ! Absolutely not enough trust. Tried one time and wasnt able to launch (just go down after launch at max RPM).

Next attempt:
Graupner Speed Cam 5,5 x 5,5

and then:
Speed 480 7,2 V and CAM SPEED 6 x 3

Lets see !

Ciao

Just some fun ... with a wireless cam on my TS2.

That should be interesting. (the video)

Wonder if anyone has tried the carbon zagi 5X5 props?

http://www.zagi.com/index.php?main_p...roducts_id=114

There is a propellor test at Bumpy Green, they recommend the Windsor: 6 x 3.5 (similar to Master Airscrew) and the Kavan 6X4 yellow bendy prop.

here is the link, you have to search for "prop study" then go down the results page to "Bumpy Green Model Aerodrome: Speed 400 Prop Study" and click. tt

What country are you in? 40MHz is unusual for a flying models.

Okie dokie, this is what i have tried over the weekend.

1) Tried using GWS direct drive 5 x 4.3 prop, current drain is 24.5Amps lots of speed but not enough trust. The bird was climbing with difficulty.
2) Tried using GWS gear drive 6 x 5 prop, curent drain is 26Amps, lots of trust. The bird was climbing well enough.
3) tried using GWS direct drive 6 x 3 prop, current drain is 25Amps. Not enough trust, but the bird is flying as good as the standard prop that comes with the plane.

NOTE: i am currently still flying with Speed 400 6V. Not sure if i should change to 480 7.2 as the later can only provide alot of trust and torque but not speed.

Maybe i will change to Motor Max 400F brushless outrunner to try hee hee.....

Will continue to explore and update all again if i am able to find the best prop for the original speed 400 6V motor.

Cheers

Hi Tony

We uses 40Mhz band in Singapore as well.

Dear TwinStar II owners,

I just got myself an APC 5 x 5 direct drive prop. Again i will try it this coming weekend and provide my findings after that.

Cheers
Kelvin
