These are a great upgrade for the 1550... the added strength is fantastic. Easy to fit following the video. There is no instructions and no one mentions in the videos which ram goes in what position, so I will tell you. The long ram is along the top working the second arm. The short ram is for the bucket. The medium ram attaches to the cabin and lifts the first arm. It is important because the long and medium rams have the hole thru the servo in different location... if you accidentally set up the medium ram on top, the hole for the servo to sit in will be in the wrong place when you fit the correct long ram. I recommend these rams for adults wanting realistic digging.... when you also get the joystick type transmitter, the 1550 really comes alive. I was nervous to fit these rams, but after watching the videos on youtube (there are a few) when I actually did it, it was really straight forward and easy really for anyone who is confident with tools. Another benefit of these rams is they allow more range of movement when closing the second arm and the bucket range of movement is increased, especially when, as I did, you remove some of the plastic reducing the arms range once the gears are removed from the arms. When parked, the bucket can come further in between the tracks and the first arm can be much lower. One important note, you have to be mindful of the range of the arms, with the strength of these rams, the arms risk breaking if the button remains pressed when the arm has reached its maximum... or the board or servo may burn, so care is needed.

Right now I unpacked the first upgrade for my new rc excavator HuiNa 1550. It only took 10 days to transport from China to the Czech Republic, I am very satisfied! The screw servos are very nicely made, it will be a really big improvement of my model :-)

هذه رائعة، أتمنى لو كنت طلبتها في وقت أبكر تحول حفاراتي بالكاد إلى صفقة حقيقية

These are so good on the Huina RC excavators, I bought 3 more sets. Even tho they are plastic gears, they are very strong compared to the weak geared arms these replace on Huina excavators. No more clicking! Yay! Note: The longest ram goes on top of the main arm to the dipper arm... the medium lifts the main arm... the short one does the bucket. Makes the 1550 really dig well.
