Wow, that is incredibly helpful, calvinwill. I will be sure to do exactly as you specify. It's really good to know that I am not the only one who has done something like this. And yes: good idea to make sure it works before putting the upper hull back on!

About the gun stabilizer unit, thank you. I did do everything the instructions indicated. But when I try to set it up according to the instruction manual, using the transmitter, I can never get it right, it seems. There is no electronic sound emitted, which the manual says is the signal that it's turned on. Does your stabilizer unit definitely work? Anyway, this is less serious and I am sure I will figure it out. I just want to get my Leo to turn!

Thanks again for your fantastic ideas. Hopefully by the time your'e back on Saturday my Leo will be in business.
