Control Surface Throw Gauge - Self assembly tool that features movable backplate (which shows +/- 55mm movement) for Zero setting, simple foam padded clamp & ball raced steel pointer with counter weight, perfect for setting accurate control surface throws on medium to large models.
Very pleased with this kit, took some sorting to establish how it went together as there are no instructions with the item. However the sketches in file folder suffice and it is now working well. Make sure you push the bearing fully home in the boss so it is flush, and the pointer moves freely.
The cross-section photograph in the files tab is correct and send method.
Nice deflection gauge, helps make sure that control surfaces are where you want them based on gravity not relative to any of the aircraft surfaces.

I received mine yesterday. It doesn't come with any instructions for assembly. I had a hard time figuring it out. It seemd simple enough. I added a nut between the bearing and bushing. This allow the arm to swing freely and allow for the scale to be tigh engoung that it could be moved moved to zero for any any airplane. It is as mentioned in degrees and not mm. The results are far more accurate than the ruler method that I have been using for years.
