Flight report
In the meantime, the Addiction EP have 51 flights, one day was enough to trim the model 100% (it has flown from the maidenflight 90% perfect )
I have tried many, many things and I need really only two very, very small mixing for a 120% perfect, absolutely neutral flight characteristic!!!
one mixing : elevator (up and down) to rudder left 1 mm ( could be a question of the torque of big prop)
second mixing : rudder to elevator : in knife edge 1mm elevator up ( this could be a question of angle of setting and GC, but because upline, downline and the groundline are absolutely top at each throttle position; I see no reason to change something)
Until yet, I never have had a model which fly perfect with such less mixing!
I´m really happy with the Addiction and it is sure since the very first flight: this construction needs no modifications. Congratulation to the Starcraft company!!!
All details at the Addiction works fine; incl. the motormount, the cooling system of motor and batterie, the fixing of batterie, canopy, belly pan and wings ….
I have tried APC 21x13 WE ( good but with 130 grams heavy) and APC 21x14 E ( 109 grams; good at very strong wind but I feel to fast at normal wind conditions).
I decide to fly with my last year carbon prop 22x12 (weight 90 grams); with the better voltage of the new ThunderPower extreme and the low resistance of Addiction, I could fly with the same prop more groundspeed ( if needed at strong wind) as last year with the Beryll (that´s what I want!).
The power upside is great. To fly " constant speed" at normal wind condition, I only need 70 % of full throttle upside; 450 U/min less from maximum 6380 Rpm (static)
( in upside flight max Rpm at 100% throttle 6660 U/min, reading from the Spin controller) with prop 22x12.
I fly three flight conditions: no wind, wind, strong wind with 70, 85 and 100 % max. throttle ( at controller fixpoint "on" at 2,0 m/s with Futaba RC) and other throttle curves at each condition. The advantage is the same throttle-stick position at different wind conditions but other groundspeed)
These three conditions are combine with different brakes downside. Fixing point at low throttle 1,1 ms at Hacker Spin 99. Initiale point of motor 110 % at Futaba, only to activate with additional switch at transmitter ( add. security(!), the motor never runs, if this switch is not activate one time); full brake/low throttle at normal and wind condition at 96% low stick position; low throttle position at strong wind 93% (no brake upside). Add. I could switch the brake "off" ( position 93%) for 45 upside headwind flightlines at normal and wind condition with a stick switch.
The first brake of Spin controller aktivate after 0,9 sec. with 14%; after one secound later, the secound brake activate with 26%.
With this trimming, the Addictions is flying a perfect constant speed at each wind condition ( from slow at normal wind condition to faster at strong wind) with the same stick positions of throttle stick!
It is striking, how easy the Addiction manage turbulent wind; the model is very easy to handle at crosswind.
With aileron differtial upside 80%, downside 100% all rolls are a show, The snaps upside / downside are very clean and solid and one of the Addictions strong points is, that all snaps stopped faster you can see!
The Addiction turns very stabile on the spot and have no tendency to swing downside.
At knife edge the fuselage is horizontale and needs only less ruder; no rolling tendency.
The best way to describe the Addiction is, that it presents extremely well and smooth all things in the air ( and at the buttom also!!) .
The Addiction is a very good looking, pure flying machine with characterics over all, I never have had in one model before.
Addiction, Zeque, Astral XX, Aries and other; I´m sure, this is one level.
But the Addiction is the one and only original japanese model you can buy outside Japan and the EP-version is a special up to date construction for electricpower with removable canopy, belly pan and two part wing.
It´s a top, very solide traditional wooden-workmenship with the unique japanese "dream" quality finish.
Each millimeter of this plane justify the price, which is not cheap but thze bresult of a honest work. The price is on the level of other top-world class F3A-models.
I´m really impressed and in love....... and I have ordered a secound!
All of you a good F3A season 2007!
