Villa,

I don't completely trust the uprights on our tables, if I can get one free and unused. I've had a plane want to climb those. I tether mine to the table legs when I need to do a big adjustment to the needle valves, or have somebody hold the model. Usually, the holder is always wanting to give me advice which I can barely hear over the engine anyway. I hate being distracted when an engine is running and it isn't safe to divide ones attention like that.
