I think this set can't have proper dual pendulum suspensions like 42070. To have that, the rear mounting point of the last axle must be behind the 5x7 frame that houses the differential. 42070 has that set up, so it can have dual pendulum. In contrast, the rear mounting point of the last axle in the 42114 are on the sides of the frame. I think I can only make the second axle pendular, and that should already be sufficient, -
Which type of suspensions for the rear axles is suitable for this set? Is dual pendular suspensions (42070 suspension) or dual live axles (42043 suspension) better?

Found a mod by chefkaspa on rebrickable for the green button access when the control+ hub is used.

The pdfs are all accurate.

Thanks a lot!!!

@efferman Where can I download the file for the version with the foldable wings?
-
Yes my bad. The 20z gear in the bottom should be changed into a 12z as well.
-
In the instruction, page 130 & 131, which is step 161 and 162, replace the 3-side black brace that meshes the black 12z gear with the tan 12z half gear wth a 3L beam and replace the black 12z gear with the tan 20z gear. Move the tan 12z half gear to the right 0,5 unit and add the white connector as a bracer. In page 251, step 319, replace the 12z half gear with a 20z gear. Remove the 3-side brace. In page 255, step 324-325, add a -o- connector between the two connector points of a small turntable. Then add a 2L axle connector + a red 6L axle from one side and the 12z gear on its way in. The result is like this.

20z means 20-tooth 20-z gear refers to the 20-tooth gear, bricklink code 32269: 12-z gear refers to the 12-tooth 1-module thick gear, bricklink code 32270 12-z half gear refers to the 12-tooth 0.5-module thick gear, bricklink code 6589 You can find the parts number at the end of the instruction file. Go here for a complete guide on how to build your own model: Can you do the instructions for my mod as well?

What's your setup for the steerable front wheel? Can you share some photos?

Control+ General Discussion
Ngoc Nguyen replied to Jim's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Since TLG has released a powerup/control+ compatible dumb battery box, you can buy the control+ motors and wait til the dumb battery box is more accessible and stock it too -
You can check out the part lists first post or import the XML code in the first post into bricklink.

Having no idea that the set violates their policy and having no idea that the set chews gears are equally laughable

TLG bein' funny

There is

This clip shows the gradual deformation of the bottom 8z gear.

Gear reduction mod explanation: First replace the 3-side black brace that meshes the black 12z gear with the tan 12z half gear in the yellow axle with a 3L beam and replace the black 12z gear with the tan 20z gear. Move the tan 12z half gear to the right 0,5 unit and add the white connector as a bracer. Then add two 20z gears into the rotors.

Sempai finally noticed me!

Even Sariel isn't spared from the inadequate drivetrain and clicking gears. https://youtu.be/fPKqUrwRIqk?t=282 My heart ached upon hearing that sound. Poor poor little Osprey. At least mine received treatment now.

I have the set but can't really confirm it because I rarely turn on the blades, and now that I have implemented my mod to ease the stress on the axle, I don't think I'll encounter this problem.
-
The spinning blades do have an overload protection mechanism, but it doesn't kick in. When I blocked the blades with my finger, the motor stalled completely. My reasoning for the mechanism's failure to activate effectively is like this: When the blade is blocked, the torque required to spin the blades suddenly increase, and is larger than then torque transmitted from the motor. In order for the motor to slip, the torque from the motor must be larger than the friction torque of the linear clutch. Unfortunately, because of the missing gearing down, the drivetrain from the motor keeps spinning and try to spin the blades. Replacing the linear clutch with a new clutch that slips more easily doesn't solve the root problem. Because the torque from the motor is already insufficient to drive the spinning blades, if the clutch slips more easily it will keep slipping.
-
That's an acceptable price for a rare set. Think of it as buying a 2H flagship. I bought mine for the equivalent of 209$. The VND price on the box was equivalent to 262$, but luckily for me there was a 20% discount sales. But I was ready to put down 262$ when I stepped into the store.
-
Yes there is. The spinning blades only worked fine the first time I turned the function on for the first time. The gears always skip and click after that. The 24z gear doesnt fit, because its diameter is larger than 3 modules. It was already used in the spinning blades of 42025.
-
Even if the clutch is substituted with one with lower tolerance, that still wouldn't solve the problem: the motor is inadequately geared down. In my model which included the default linear clutches and the gearing down mod, I've just tried blocking the spinning blades. The motor still delivers power just fine. No stalling at all. So the clutches isn't the real problem.
-
There are two friction-based connector-built linear clutches in the wings. Ideally they should have had low tolerance and slip even at the tiniest obstacle, But it turns out that the clutches have quite some high tolerance, so if the blade is blocked the motor will actually stalls instead of continuing to deliver power to the clutches.
