This is where the work pays off!
To close the loop on the on the VQ Warbirds B-24 Liberator, this week we’re going in depth on the radio setup, CG and flying of this beautiful scale model! This is such an impressive airplane and it truly does not disappoint in the air. This is one that I’ve thoroughly enjoyed having it in my hangar and I’m looking forward to bringing it out to some events later this year.
Interestingly, when mentioning heavy bomber aircraft of World War II, undoubtedly, the first bomber that comes to many peoples’ minds is the Boeing B-17 Flying Fortress. However, few realize that the Consolidated B-24 Liberator was built in greater numbers than any other US bomber of WWII. Given the B-24’s distinctive twin rudder design and high aspect ratio “Davis” wing, the 4-engine heavy bomber provides an unmistakable shape. The airplane was designed for a purpose and it served that purpose well throughout the war with over 18,500 total B-24s from 1940-1945. The B-24 served in every branch of the American Armed Forces during the war and in fact, offered greater range, greater speed, and greater bomb load capacity than the B-17.
WHAT’S IN THE AIRPLANE
To recap from the assembly review, this B-24 Liberator is a great sized ARF of all wood construction coming in at a 110″ wingspan. At final ready to fly weight of 26.5 lb the airplane doesn’t even notice it at all in the air. From day 1, this airplane flew straight as an arrow requiring only just a couple clicks of aileron trim on the maiden. The power from the 4 Himax motors and Master Airscrew props feels absolutely perfect for the airplane as it has plenty of thrust at full throttle, but still cruises around at partial throttle easily and efficiently. Here are the final specs and equipment that were used in the airplane:
- RADIO – Spektrum Dx18, Spektrum AR12310T 12-Channel PowerSafe Receiver
- RECEIVER BATTERY – 2x Spektrum 6.6V 2200mah 2s LiFe Battery, 1x E-flite 25c 3s 800mah Lipo Battery and Castle Creations BEC set to 9.0v for retracts
- SERVOS – Hitec D-645MG (ailerons, elevator, steering) and Hitec D-85MG (flaps and rudders) servos
- MOTORS – 4x Himax HC3528-1000 outrunner motor
- FLIGHT BATTERY – 4x Roaring Top 35c 4s 4300mah Lipo Battery
- ESC – 4x Castle Creations Talon 60
- PROPELLERS – 4x Master Airscrew 10×7 3-blade
- RETRACTS – Robart Electric with Scale Wheels & Struts
- TURRET CONTROLLER – 2x Random Servo Motion Generator
- MARKINGS – 834th Bombardment Squadron “Scorpio” (custom markings from Callie-Graphics)
AIRCRAFT SETUP & CG
In flying this airplane, I found that the recommended CG and control throws in the manual were spot on for the model and I found no reason to adjust any of them. The airplane does have a big high aspect ratio wing and you do visually see the resulting Continue reading
