Non Lego RC Motors

[yoraish]

Hi.

I was thinking for some time now that I want more power and speed in my trucks. So I thought non Lego RC motors will do the job. Did someone already do something like that? And if not, how would you suggest me to do that? Maybe even coupling many XL motors?

Thanks!

@ Yoraish: If you want to go to the "dark side of The Force" , then Bill's Brickland (a Bricklink store in Florida, USA) has a Servo Integration Kit and RC motors that allow Lego Technic Liftarms to connect to commercially-available RC motors! The store is also known as Inanimate Reason -- you can find the kits in the "Custom Items" link at the left-center (dark blue) part of his Bricklink store webpage. The owner (Bill Shaw) is really into Lego-compatible Robotics. Here are the links to Kit 1 and Kit 2.

Kit 1: "Bring the power of large, hobby scale servos to your robot or vehicle with this large servo adapter kit! What could you do with the brute force of 343 oz-in of torque like you can get from the Hitec HS-805BB Servo? It works equally well with large sized servos from Hitec. Our servo connection plate can adapt to Lego plastic axles or 3/16 steel axles (one 4L sized axle of each material is included. We include set screws for both types of axle.

The plate also features integrated mount points for LEGO® liftarms and our custom aluminum liftarms.

You can also attach liftarms or other Technic® compatible elements to the face of our proprietary horn. The horn adapter is designed to mount to Hitec large servos(or other brands who conform to their designs).

Inventory of the complete kit:

1 large scale aluminum servo connection plate

1 large scale servo horn adapter

1 13 mm steel shaft (4L)

1 4L LEGO® axle

1 ea set screws for steel and LEGO® axles

4 pcs mounting hardware for plate

4 pcs mounting hardware for horn

assembly instructions"

Kit 2: "Imagine powering your robot or vehicle using an off-the-shelf hobby servo motor! It works equally well with most standard sized servos from Futaba and Hitec. Our servo connection plate can adapt to Lego plastic axles or 3/16 steel axles (one 4L sized axle of each material is included. We include set screws for both types of axle.

The plate also features integrated mount points for LEGO® liftarms and our custom aluminum liftarms.

You can also attach liftarms or other Technic® compatible elements to the face of our proprietary horn. The horn is designed to mount to either Futaba or Hitec (or other brands who conform to their designs). Our unique horn design gives you the option to use either size standard without having to worry about which horn you happen to have available.

And here it is installed on a Hitec HS-645MG servo:"

Have any examples of a working finished product (i.e. car, truck) with instructions for building from something like this?

I was thinking for some time now that I want more power and speed in my trucks. So I thought non Lego RC motors will do the job. Did someone already do something like that? And if not, how would you suggest me to do that? Maybe even coupling many XL motors?

The XL motor already exceeds the strength of ABS LEGO parts and will twist axles and break gear teeth. Sure, you could find a way to attach an R/C motor to a LEGO model, but the torque of the motor would immediately destroy your parts. There's only so much you can do with snap together plastic parts. If you want R/C performance then use parts made for that purpose.

i suggest you use the white slipwheel somewhere in your system?

i always do

Pretty interesting RC servo mount for Lego up there. As for Non Lego RC Motors It very possible to use them with Lego but there are some inherent limitations with Lego parts. One problem here is transferring the RCs motor powerful torque through the Lego differential. I wouldn't worry about twisted axles that much coming from a RC motor but one of the big problems that you can encounter is a friction welded axle that has friction welded it self to another Lego Part. Now out side of that you might break a couple of weak brittle gears along with a U-joint or two but other then that the Lego drive train can handle the power from a powerful/fast RC motor.
