RE: Quark
Is suggested to purchase if you can at the LHS Local Hobby Shop, in our area midwest Illinois closest dealer is Hobbytown USA, they are likely able to find one for you if not onhand, else the mail order, YRBUY has the best price on the Quark and found great on odering parts as the foam blades...<>..only part needing attention on mine..sounds like your ready for the Quark, really enjoying mine todate, nice piece of work....BEST and Good Luck...
My selected armada on helis that flew, many more but these worked for me todate...<>..
Eflite MCX coaxial
Hirobo SRB Quark, off the chart for a mini FP, built like a battleship, a beauty..<>..
Eflite Pro 2, touchy but am hovering, tnx to the Quark...
