4B100 scale helicopter quick review

[ehirobo.com]

Base on the poplar 4#3B double brushless helicopter. Walkera had release the new 4B100 double brushless helicopter. With scale fuselage makes it a very nice little helicopter to fly indoor when the weather is not good outside. Side by side with the 4#3b you will notice the main rotor parts are identical to the 4#3b metal upgrade helicopter, which feature full aluminum rotor. The flybar is slightly longer (by 12mm each side). And the boom area have a lot more reinforcement which should makes it more durable. The total weight is slight more than the 4#3b double brushless. (65.3g vs. 69.7g) With the same double brushless system mean you don’t have to worry about the issue with brushed motors anymore.
