Could you tell us what the weight is of the model without power system? This will help me decide on which power system to put in my own AcroMaster. Thanks!

550 gram for all EPP parts, plastic parts and control linkages/hinges and undercarriage.
So add a propellor, motor, lipo, servo's, ESC and RX and you have your AUW.

Is that 2820-10 similar to the Eflight power15? Seems close to me.
Ryan

edit: I guess I meant the power 10, it has a 1100kv vs the 15s 950

Yup im also eagerly awaiting reports. Considering to buy one after my Superzoom.
I have a NIB AXI 2814/12. Would that work? Would be using the new Flightpower evo20 3s 2150mah packs.

Thanx!

Axi 2814/12 will generate 1750 grams of thrust with 12x6 APC Electric on 3slipo/40A...
www.flyingmodels.org
Will do for acrobatic flight, maybe not the best pull out of a hover.
Most people over here in Europe go for the 2820/10 and over 2000 grams of thrust....
Started building today, have to wait for servo's though.
First flightreports I read on www.rcline.de are very good, very neutral flyer with a low wingloading and very slow in landings...

With the 2814 and a light pack maybe the pullout is not that bad . Try to save weight in the details , light gauge wiring , avoid unnecesary connectors ,etc.

What pack will you use for the 2820 ,pjotorr?

Cheers.

Oh ok.
Thanx for the heads up guys.
My next biggest motor is the AXI 2826/10. Seems too big though.

Thanx!

I already had a Polyquest 4s3100/12-16C pack and bought me another one now they are cheap at www.aircraft-world.com
On 4slipo the motor only draws 33A max or so and this 4spack is almost the same weight as the 3s Kokam 3200....
I live 10km from the beach, always windy around here so I don't mind the AUW of 1150 grams.
The AcroMaster has a VERY light wingloading, wing area is the same as the 140cm span (30 cm more!) Hyperion Yak54...
A good light (1050 grams AUW) setup is possible with the advised Himax or an Axi 2814/12 and small 3slipo 2200's or so.
The advised Himax 3516-1130 (134gr) outrunner is in between of the Axi 2814 (106gr) and 2820 (151gr) and cheap so....

Instructions and FMS model

For those of us that don't yet have Acromasters, the instructions were just released on the Multiplex website:

http://www.multiplex-rc.de/cms/vorsc...master_5sp.pdf

They appear to be very good instructions, the kit appears to be very complete, it has some very helpful trimming tips, though it is probably a little more involved than most Multiplex products.

Per Multiplex support, they will not be creating an FMS model. That's too bad because that's one thing I've really liked about Multiplex products - being able to practice at home at night or rainy days.

Hi friends,

...I´m new in this forum - so first of all hello to the comunity!
As you can see, I come from Tirol in Austria - so please don`t be worry if my english sounds a bit "scary". I hope it will be better by reading and writing some posts.

Now I want to post some infos to the Acromaster - maybe I can answer some of your questions:

The kit is really fantastic ("clip on" landing gear, motor mount, stability...)
My first setup was:

Axi 2814/16
APC 11x5,5 E
Jeti advance 40
Tanic 3s 2080
4x HS 81 Servos and schultze 8.40 receiver

With this setup the weight was 1,010 gr.
The performance was very good. Starting on gras (with the beautiful "wheelcaps" ) was no problem - not more than 5or 6 meters. It flies absolutely easy! You can fly it very slow - if you can handle a Twinstar or something else with ailerons - you will have no problems and much fun!
Aerobatics are very exact - especially snaprolls and "kniveflight"( ) looks great. Perfect for aerobatic training! I tried also some Stall figures (3d) so far I can do it ( ) - it works. With my setup you can park the AM in the air.
Flighttime was appr. 6 minutes (max. 31A).

But I think there will be a better setup: the Axi 2820/12 with 12x6 Prop will have a better performance. The more of weight is really no problem, but it will bring more power for real crazy manouvres (the AM can do - you too ? )
Flighttime is from 8 to 12 min., also not more than 30A during flight - but a bigger Prop (a user in germany tested this setup and he was very satisfied - he sells hyperion planes in germany an his flight performance is much more better than mine )

So I can`t wait for the next flights - relaxed aerobatic training - no fear about the costs!.....ähhh....maybe I will need new lipo packs in the next weeks...

Good flight
Walter

Dear all,

My AM is also finished. The Kit is very nice and complete. Easy to build. Mine is equpped with:
Kontonik Kora 10-16
APC-E 12x6
Kontonik Swing 4100 Lipo
Hitec HS81 and HS50
Tanic 2480 3s

Wight is 1040g. I've installed a nightflight equipment with LEDs monted inside the plane. Yesterdays flight at 10:30pm was nice. Visibility is very good.
The setup develops plenty of power. I've recorded 45A static current consumption and 33A max during flight.
Finish is also a bit different, I will post pictures when it is finalized

I'm thinking of using a geared inrunner on my AcroMaster. I looked over the manuals on Mpx's web site, and it looks easy enough. What does everyone think of a Mega 16-15-3 (or 4) geared 3:1 on 3S spinning a 11 or 12 x 6 prop or so. I'm guessing around 25A, so 15C 2100s should be about right. I'm hoping to keep it pretty light, and fly more pattern than 3D.

Might be good . I have a big depron (1.4mt, 1200gr) with a 2 turn mega in a 6.1 box turning a 14x7 and has a very good pull and a good speed for pattern , but it ask for 50amps from a 3s pq3700.
I think 300 watts is the minimum for good acro (master).Look for 30+amps.

Cheers.
