Awesome LEGO Technic Helicopter Review and Modification

We were recently sent a LEGO Technic Twin Rotor Helicopter, set # 42020 by our friends at LEGO. The opinions and ideas in this article are our own.

Jacob (8) and Jordan (6) have been begging to be part of my blog for quite some time now. They spend countless hours following their favorite YouTube channels featuring little kids opening new toys and reviewing them. For those of you who have not been “blessed” (and I use that term loosely in this case) with watching one (or rather 157) of these gems let me inform you that these box openings and reviews are called “epic unboxings.”

Thanks to our friends at LEGO, the boys were able to have their own EPIC UNBOXING recently of the LEGO Technic Twin Rotor Helicopter, Set # 42020. To say that they were thrilled is a gross understatement. They decided that THEIR YouTube channel should be called “The Great Js!” – don’t tell them that I set their video up under my name! (Shhhhh)

The kids were first introduced to LEGO Technic a year ago when they attending their first Bricks 4 Kidz camp. LEGO Technic is all the things you love about LEGO – and more. The creations feature gears and wheels, which brings a whole new level of creativity and engineering to play time. Jacob and Jordan each have a battery box and motor, which can be added to any of their creations to facilitate the spinning and turning of the gears – kicking things up 100 notches!

The twin rotor helicopter that we had to build is a 2 in 1 set, which means there are instructions for two different creations. The kids decided to build the twin rotor helicopter first, and then modify it to fit the motor.

For the MODIFICATION you will need:

LEGO Technic Twin Rotor Helicopter, Set # 42020

LEGO Functions Power Functions M-Motor 8883

LEGO Functions Power Functions Battery Box 8881

(Instead of buying the motor and battery box separately, I got the kids the LEGO Technic Power Function Accessory box (8293), which also includes lights and other fun things to add to the engineering creativity)

One black connector peg, which comes extra in the set.

MODIFICATION INSTRUCTIONS:

Build the twin rotor helicopter according to the instructions.

Remove the grey cross axle extension in the front of the helicopter (watch the video)

Insert black connector peg
Line connector up with holes on the motor, insert motor
Connect motor to battery box
VOILA! You now have a spinning helicopter!

Favorite features of set # 42020:

• It is a 2 in 1 set and it comes with two instruction books, so lots of creative variations.
• The set costs less than $15, making it a perfect TECHNIC starter set.
• It is a compact set and therefore is perfect to bring along on vacation.
• The helicopter was easily modified to fit the motor.
• The final creation is solidly built and doesn’t fall apart during play.

Final verdict:

We love this set for its versatility, affordability and potential for expansion. (We will stock up on these as birthday presents to friends.)

I urge you to watch the video – it is EPIC!

Let Jacob and Jordan know in the comments what you think of their first YouTube video. They are anxious to do more in the future! They really want to hear what you think! THANK YOU!
