I got mine second-hand - no manual! Don't think there was any mention of it in the Minimag manual, though.

The Minimag instructions do not mention the technique, probably concentrating on the different adhesives to be used, depending on the prop used.

Well, I've apparently got my manuals mixed up. Thanks for catching it Jürgen. I was correct in that some manuals mention it, and some don't. It should always be done though.

flew my twinstar2 and i love it. i think the stock power setup is fine. with my 7.4 apogee 4160 lipo it was very floaty. i've flown planes with less power stock and i was pleased how slow i could fly. took me a few practice runs till i was comfortable landing, the darn thing just didnt want to come down. and it flew inverted with all most no down stick at all. very stable.

this is my first multiplex plane and it wont be the last.

with my battery i flew over 20 mins.

cant wait till the batt charges.!!

alright!!

i just had my second flight, another great flight. managed to get one skid and go in, that is really fun. my little boy wasnt really interested in the plane till i did that. was a bit breezy so it was a big difficult to get her down smooth to skim the grass.

so far i really like flying slow and low. i like buzzin myself.

and its sooo quiet.

i ended up buying a great planes electrifly c-35 and i like it, very smooth.

i too would like brushless. just a cheap outrunner to swing a more thrust friendly prop.
any of you guys try the bp motors. thinking the 21 with a 8/3 or 9/3 prop. i dont want any more speed, just climb authority

Sebz, your Twin Star looks great. The yellow and blue contrast really sticks out.

And besides...what man in their right mind would actually read an instruction manual anyway!!!

One that wants to build a plane correctly.

Page 26 Twinstar II manual:

Apply a little glue to the bore of the plastic spinner using the point
of a pin, and push the propeller onto the motor shaft. Push the pin
through the rear of the spinner to allow trapped air to escape.

Thanks jcosta. Now I don't have to go looking through the manual for that info. I honestly haven't used one of those type props for several years now. I do know that others do and I'll be sure to pass on this information. I'd never of thought of it on my own. FWIW, I've never 'glued' a prop on either ...'course I've only used that type of prop on pusher type flying wings, but still lost props occasionally.

No need to go brushless just for that. Just use some long can 400 (Permax 480, 7.2V for example) and Graupner Cam Slim 6.6x3". Swapping the motors should not take long. Re-routing the wiring and installing two ESC's is a much bigger job.

i do like the brushed power with exception to the lack of climb, but i have 2 similar speedy's and i wouldnt mind trying the brushless since the motors are even cheaper then the 480's, but i do believe you, i'm relatively a noobie when it comes to electrics.

would i get all i could running a 2s lipo on a 7.2 motor

i'm running my 2s at about 150-160 watts. right around 20 amps. on the stockers

how many amps does the 480 draw on 2s with that prop

and thank you for the help.

d

btw, i LOVE the video's. i would have never thought a plane the size of a ts2 would be and indoor flyer!!! and i want one of those gemini's havent seen those out here.

Pin hole in Spinner of Günther Prop

Those of us who have had Graupner's MINI PIPER are well aware of the need for the pin hole in the rubber spinner.

I have mine running on Warp 4, 5 turn motors running APC 8x4E props. Total power is ~350 watts with a Hyperion 20-30C 3S-2500 pack. AUW is 42oz and this setup will go vertical no problem. I actually enjoy flying it like a LMR glider, 15-20 second climb to speck height, then see how long I can keep it aloft. With the ESC brakes on it glides absolutely awesome and I have been able to thermal it a little but haven't had the best thermal conditions to really test it out. I also use it for AP duties occasionally, it is by far my favourite all round plane.
