The Quantum can not be said that there is no note both in ground and in air because is original for the lines (reply of the "big brother" Tomhawak turbine (questionable and obviously susceptible of pleasure or not), one model that stands out and attract attention. The components installed (edf, motor, esc, retracts) is the same used in other models Tafthobby; the gear retracts work precise, edf with good power and absorption is average of edf 90mm; with a good engine management permit to fly for about 5 minutes (but much depends the state and the quality of the batteries).
My opinion is positive and applaud Tafthobby that with his last jet (the Valkyrie before, the Quantum now and the Scorpion is coming) is distinguished from other companies for the courage to experiment and to market innovative products that undergo it new and increasingly severe judgments of end users,we insatiable modelers!!!
VERY WELL TAFTHOBBY!
