iFlight Alpha A85 HD digital

iFlight Alpha ist ein 85mm Whoop mit 2 Zoll Propellern und der Caddx Nebula DJI Digital HD Kamera und Vista Modul. 85 Gramm leicht, gute XING-E 1303 5000KV Motoren, SucceX-D 20A F4 AIO FC, Mit 4S 450mAh Akku ca. 5-7min Flugzeit. Banggood verkauft die neue Version bereits mit den 13030 Motoren und dem aktuellem Frame mit 4 Stützen.

Video – iFlight Alpha A85 HD digital Whoop

Alpha A85 wiegt zwischen 85 und 89 Gramm – hier mit CrossFire Empfänger

Flugfertig mit einem Tattu 450mAh 4S Akku

Innen sitzt ein F4 FC mit 20A ESC’s, oben drauf ist das Vista Modul zu sehen

Die Nebula Kamera ist die aktuelle V2 Version mit einem besserem Bild, überträgt das Video in 16 zu 9 mit 60 Bilder pro Sekunde unterstützt aber kein High Quality Übertragung mit 120 Bilder pro Sekunde wi es die original DJI Kamera kann.

Wie hier zu erkennen ist das die original Antenne vom Vista Modul. Mein Alpha85 ist von mir zusammengebaut aus iFlight original Komponenten ausser der Antenne

Hier meine Crossfire Antenne die TBS MiniMortal. Original wird eine iFlight Crossfire Antenne verbaut.

Der Tattu 4S Akku kann längst oder quer unten montiert werden. Mit dabei ist eine Carbon Platte die zu Stabilisierung vom Frame dient. Ich habe die Carbon Platte aber späte entfernt, weil diese nicht so wichtig ist.

Unbedingt beim Kauf darauf achten dass man den Alpha85 mit den neuen 1303 Motoren bekommt, wo der Propellerschutz auch 4 Stützen zum Motor hat. Dann ist auch die neue Nebula V2 Kamera eingebaut. Am Anfang wurde der Alpha85 noch mit den 1205 Motoren und der alten Nebula Kamera gebaut.

Den Alpha A85 gibt es auch als analoge Version mit normalen Kamera oder sogar mit einer 4K Kamera

iFlight Alpha A85 85mm 4K Loris Kamera – analog – Banggood Coupon: BGTT10 – https://www.banggood.com/custlink/3vvm7JzNOC

Gute iFlight XING 1303 5000KV Motoren die aktuell bei iFlight Alpha 85 verwendet werden. Sehr gut für TP3 Toothpick 3S Quad https://www.banggood.com/custlink/DmDdCjRIP8

Ich habe bei meinem Alpha85 unter Betaflight die Firmware 4.2.4 installiert mit den original Einstellungen. Habe aber folgendes geändert
set thrust_linear = 25
Das reduziert das Wobbeln nach links und recht. Diese Einstellung sollte man bei allen Whoops einsetzen, da diese meistens zu schwer sind.
