peccato... un modello visibilmente picchiato (ondeggiava paurosamente sull'asse di becheggio nel volo orizzontale) un decollo non perfetto e un atterraggio pessimo.... avrebbe almeno potuto evitare di abbassare il carrello in aterraggio... visto le difficoltà nel controllarlo almeno salvava il carrello...

Murphy era un ottimista: AMD Hawk with 120mm EDF - RC Groups

questo a casa mia si chiama "dare il pane a chi non ha i denti"....

quoto comet....

pessime scelte durante il volo, il modello visibilmente picchiato, scarsa controllabilità sull'elevatore, atterraggio impostato male e continuato........

Per tua/vostra informazione:

"It was Steves first flight and it was set up too sensitively for him, also it was a gray model on a very dull day. However it gives some idea of the performance."

"Our Hawk is nice and stable in comparison, I think the EDF Hawk looked tail heavy. Also the pilot likes exponential but had none dialled in."

"Frankly I was surprised at the way it performed. Dave Wilde and I have flown this model many times with Wren MW44 and also with the Super Sport, and we were expecting it to appear very underpowered. The takeoff roll was not long and the plane jumped into the air. It was a bit tail heavy and this affected the takeoff and flight as Steve struggled a bit with it.The plane had a pleasant noise not unlike a quiet turbine and it had a good turn of speed. There was plenty of power for loops and rolls.
Interesting now that turbines, Ducted fan and EDF can power the same plane! The weight is very similar for all 3 configurations except the turbine version will be heavier at takeoff and lighter when landing compared to the EDF version."

quindi.....

continuo a dire che con un modello che si comporta in quel modo non faccio tutti quei circuiti, atterro metto a posto quello che serve e ricomincio.. con tutta quella pista a disposizione fai un atterraggio del genere?? dai,... ridava motore e si ripresentava.....

non è una buona attenuante. Il primo volo di un modello si fà solo in condizioni ottimali, che il modello era grigio e il tempo pure penso che potesse accorgersene prima di decollare... e in quanto al set up troppo sensibile.... beh può anche darsi , ma avrebbe dovuto accorgersene prima di partire e poi il modello picchiato in quel modo è evidente anche a terra .... non bisogna aspettare di essere in aria....
"Our Hawk is nice and stable in comparison, I think the EDF Hawk looked tail heavy. Also the pilot likes exponential but had none dialled in."
Ho dei seri dubbi sul fatto che fosse pesante di coda.... a me sembra piuttosto pesante come un macigno di muso... si vede da come ondeggia per i continui interventi sul cabra necessari a farlo andare dritto,,, se fosse stato pesante di coda avrebbe assunto una posizione diversa in volo.

Continuo ad essere dell'opinione che chi ha pilotato quel modello non abbia controllato bene prima i pesi, le escursioni e ....... i pollici....

ho notato che esiste 'sto po po di mostro per le ventole da 120mm... certo ci vuole un mutuo per le batterie ma .....
