Graupner UNI 2000 expert mekanik, anyone?

Has anybody tried the above on 30 cells?

I want something like that for competition use.

There must be somebody with 30 cells experience in a heli!

Hi Sture,

My 30 cell experience is limited to watching a friend fly his LOGO 30 There hasn't been much discussion about 30 cells or Graupner stuff on this bbs.....

Might I suggest asking on the E-Heli mail list? Although it is not very active at the moment, there are 263 subscribers, and this is where I first heard of the LOGO 20 from some of the European fliers who seem to be a lot more experienced with E-Helis.

Its finally flying again (after a mishap (major)). I have posted some updates and pic's to my homepage at

Its a nice heli. I am now waiting for a brushless motor from Kontronik (Tango 45-05). The motor was ordered almost a year ago (come onnnnnnnn...).

Graupner ULTRA 3300-7H motor
30 RC 2400 cells
Kontronik 40-10-30 controller (ESC)
Multiplex DS-IPD RX
Multiplex Royal MC V2 servoes
Graupner digital car servo for the tail (do not remember spec)
CSM 540 gyro
Wooden rotor blades (included)
120 degrees CCPM swash plate
5.35 kg

Kit obtained from Der Himmlische Hoellein in Germany.

Hi Sture,

Just curious, how long do you fly with one accupack and how long does it take to charge :-) ?

How many accupaks do you have ?

Flying time 5:30 - 6:30 on 30 RC2400 cells with the wooden blades that comes with the kit and the Graupner ULTRA motor they sell for this kit.

Charging takes 1 and 2 hours from my car and at home respectively. The charger is a Simprop NC Manager. With a suitable Schultze charger the charging time should be down to 20 - 25 minutes. I have two 30 cell sets at the moment. 2 sets of 30 NiMH RC3000HV cells are on the wish list.

I'm waiting for a brushless motor.

Hi sture,

Are you a shareholder from Sanyo ? Just kidding.
I have a logo10 and i like it a lot. My next heli could be a logo20 or a , i almost dare not say it, raptor. The big drawback for these pretty eheli toys on 20+cells are the flight packs. The cell count does add up pretty fast.

Why don't you look at the motors from Megamotors, Plettenberg, actro or even Hacker ? Hoellein has a lot of them, perhaps there is somewhere a motor suitable for you !

Good look in your quest for your brushless motor !

Its finally flying again! Now with a Tango 45-04 and a Beat 50-8-30. Flying time is approx 8 minutes on 30 RC2400. Its been a long journey here. I started 1 year ago ordering a Tango and a Beat. I got the Tango 45-05 this spring and a Beat later on. The Beat couldn't take the -05 motor due to overheating. Simply the Tango 45-05 didn't work. Gear ratio is 10:1.

The Tango and Beat now get barely handwarm after 8 minutes of hovering. RPM hasn't been measured yet. I am flying with the semi-symmetrical GFK (glassfibre) blades.

More updates to come.

Flight times

I'm now getting almost 9 minutes on 30 RC2400 cells in a hover. The hover is as stable as one might expect from a .60 size heli.

I just checked the price of several big el-heli's at Der Himmlische Hoellein.

Graupner UNI-E 30 cells 339,- Euro
Mikado Logo 20 20-24 cells 545,- Euro
Mikado Logo 16 16-20 cells 369,- Euro
Vario Silence 30 cells 505,- Euro

And more:
-The motor systems cost about the same for these heli's.
-The RC systems cost about the same for these heli's.
-The battery systems cost about the same for these heli's (with an exeption for the Logo 16).

A 30 cell Graupner UNI-E is a cost effective solution if you want a big and high quality electric heli. It can handle a lot of weather and is comparable to any 60 size heli.

I flew it today with inflatable floats. They have aluminium braces (1.5 lb) and the total weight at take off was approx 5.7 kg or 12.5 lb (1.1 lb increase). It flew nice and there was no significant shorter flying time. The heli with floats is MUCH easier to see in the air and they actually made the flying easier. Its snow here now and the floats worked fine on that surface, no need for digging a helipad.
