Comparing 2 SRB series models

SRB Quark

SRB Quark Second Generation

SRB Quark was designed for pilots flying Hirobo XRB or any other counter coaxial helicopters. It had single blade rotor head, which flies more similar to larger RC helicopters. With Hirobo original (Japanese patent No.4249801, international patent pending) design rotor head, this model is the most stable and easy to control among similar sized models. Flying single rotor helicopters require more skill and practice than counter coaxial models. This model is ideal for pilots trying to develop more skill to fly more advanced models.

Based on SRB Quark, SRB Quark SG is designed to Despite its size and ease of handling, SG can fly almost like larger and more advanced outdoor models. Equipped with collective pitch control, improved battery, gyro, tail motor, and idle up function, SG can now fly some acrobatics such as loops, rolls, and inverted flights. After you have mastered XRB or SRB, try and enjoy SRB Quark SG.

Main diference

Simple and easy setting

Main unit

More advanced setting possible for expert pilots

Included in main unit

Gyro

Mounted on back of the helicopter. Higher performance gyro with lesser effects from heat.

Red LED lights up while helicopter has proper rpm.		LED		LED moved to the back of helicopter. It is easier to check flight or battery condition during flight.
Fixed pitch. Hirobo original design rotor head with very stable control for beginner practice.		Rotor head		Collective pitch. The re-designed rotor head can handle more windy condition and acrobatic flights.

Simple linkage for easier maintenance.

Swash mechanism

SWM (ccpm) control used for more advanced models.

Foam blades for safer flight. They can minimize crash damage for indoor flight.。

Main blades

Made of foam, but re-designed harder main blades for handling acrobatic flights.

2 cell (7.4V 480mAh) 10 minutes flight with 1 hour charge.

Battery

3 cell (11.1V 480mAh) 8-10 minutes flight with 1 hour charge.

Shaft drive with carbon shaft.

Tail motor

Direct drive tail motor with tail mounted motor. Motor can turn more silently and efficiently.

Recommended

Pilots with coaxial model (Hirobo XRB) experience

Ideal customers

Pilots with XRB/SRB experience. Second model for pilots with larger outdoor models.

The most stable design among single rotor helicopters

Stability

Very stable. Due to collective pitch, SG is affected less from ground effect.

Indoor, some outdoor (less than 3m/sec) wind

Flight area

Larger indoor space, outdoor (less than 5m/sec wind recommended)
