Pre-ordered mine from Fast Lad UK, also ordered VBar Silverline with 2 x Spektrum sats, will use a Spektrum Backplate RPM Sensor on an OS Max105HZ, Vbar governor is very good I hear.
Servos are MKS HBL665 x 3 + HBL669 Rudder and a mini MKS HV9767 for the throttle, save a few grams there.
Also ordered a Perfect Regulator Duo Pro switch for the Glo and RX switch, prefer to connect the battery for the day but leave the canopy on between flights.
Probably use a 3800mA 2S pack for the electronics.
Not flown Nitro Heli's before, really tempted by this one, have the E7 and a TDR so should be interesting, last fired a nitro up 20 years ago!
