Maiden flight accomplished - between the Red Bull Air Race in Amsterdam and the Canadian Grand Prix in Montreal (Formula 1).

Weight RTF was 1314g and the first flight took just over 11 minutes with lot's of aerobatics thrown in. First impression: This model rocks! (and makes the old TwinStar look ....... Old! )

The new TwinStar outperforms the old one in every way. It will fly faster, yet can be flown slower. Loopings from horizontal flight are no problem. Inverted flight requires fairly little down elevator. Rolls pretty nice and axial and the reactions to ailerons and elevator can be discribed as crisp. (Perhaps I can get someone to shoot some video).

Jurgen, I have one of these on pre-order here in the UK. Am thinking about using a pair of brushless instead of the Sp400's. From the look of the motor holders and channel in the wing, there seems to be plenty of room for seperate ESCs in the motor pods.

Should I be leaving the ESCs in the Fuselage and lengthening the ESC to Motor wires, or put the ESCs in the motor bay and lengthen the ESC to battery wires????

After reading your flight report, I am thinking twice about doing this, BUT on the other hand think it would go like stink with 2 brushless

There would be plenty of room for the ESC's in the nacelles, but you would have to enlare the cable ducts. It would also ruin the simplicity of the model (it is already a bit more work due to the seperate wing panels).

On my brushless TJ I have the ESC's directly soldered to the motors. Theoretically it would be better to have the ESC's close to the battery and running long cables to the motors.

I have no intentions going brushless with my TwinStar II, but I will check whether the Permax Turbo 450 will fit.

Seems Multiplex is offering a brushless upgrade kit for the TSII. I think with one esc. Maybe their execution would be simple? tt

Interesting to me how you need two ESCs for brushless, but at least you can get differntial control that way. I think maybe a timed 400 might be a good intermediate step to brushless.

Multiplex lists some brushless motors as "tuning option" - but there won't be an upgrade kit. Two brushless motors plus two controllers cost a lot of money for relatively little additional perfomance. There is also the problem, that when the battery gets empty, one ESC will stop one motor earlier than the other - definitely not something you want during an aborted landing.

Nice shots. That thing is just crying out for landing gear... or FLOATS!

That looks great. It's a shame that we have to wait so long to get the new Multiplex products in the United States.
