Randy,
A clarification - I had nothing to do with the site I linked for you, in case you thought I did. I just happened across it. However, I am glad it was helpful.
However, if your son is interested in ships (or you are), you might want to know a bit more about RC Model Warship Combat (after all you are on this thread). One club with several links, how-to's, etc. is the [link=http://www.ntxbg.org]www.ntxbg.org[/link]. There is an article from Servo Magazine in the "NTXBG In the News) section that gives a pretty decent overview (I
did write that). There are also links to other clubs, etc.
A fun story- when my son got started (7th or 8th grade?) he was driving the Graf Spee (a club ship). This peaked his interest, and he read up on her and watched TV specials, etc. When the class started to discuss WWII in World History, he asked if they were "going to cover the Battle of the River Plate?" The teacher asked him "Which battle was that?" And he replied, "the naval battle at Montevideo, involving Captain Hans Langsdorf and the Graf Spee at the start of the war." She wanted him to refresh her memory. He proceeded - using up the rest of the class. One of his classmates was quietly chuckling to himself (he had been to a battle and knew what was going on (that Wes was basically talking about his hobby), but the results were: 1) the rest of the class (and the teacher) learned something about WWII they would not otherwise have covered, 2) Wes had a much more fun hour of class, and 3) he got an A in that class....
Anyone not knowing about the first major naval engagement of WWII, being in the waters of South Amerca, there is an article here: [link=http://en.wikipedia.org/wiki/Battle_of_the_River_Plate]en.wikipedia.org/wiki/Battle_of_the_River_Plate[/link] In view of the recent movie Valkyrie, the story of Captain Hans Langsdorf should also be remembered.
It is a pretty decent father/son activity (in fact, my son got me started, and we had 4 father/son teams at the last NABGO (North American Big Gun Open) , as I recall
Cheers,
Wreno
