I have a couple of questions regarding my 1/96 Baltimore build. First, since I have no plans yet for the Baltimore, can someone please tell me how big her props are in 1/96? Second, since I've never built anything this big before (it's 7 ft long with a beam of almost 9"), how big a motor should I be using? I'm planning on powering the inner shafts and leaving the outer shafts unpowered. Would two 380 sized motors power this OK or should I be looking at two 550's? I've also got a couple of graupner speed 400s I could use... Thanks, Carl
7 feet long? 9" wide? Better go with the 550's if you want to get to speed. Not a question of motor rpms so much as a question of torque. When are the rest of the Big Baltis coming out?
Based on what I've seen. A would say geared 550s on a 12v system. You have the weight to work with. Mike Butts
Don't use the Graupner 400s. I started with some 6V 400s on the Roanoke on 6V and burned them up on the first test. As in totally turning the the windings black and melting parts of the end bell so that it ate the brushes. I switched to 7.2 Speed 400s, but I had to add heat sinks and they are barely adequate. The geared 550s should work. I'm going to try a GWS DX370 geared system on my Tashkent, which is slightly smaller. This motor moved the 30lb St George at 28 sec/100ft using one 1.5" prop and only 18 watts. I'm used both 1" and 1.25" props on the 144 Roanoke, so I would recommend at least 1.5" props and 1.75" should also fit. Bigger is better for developing thrust.
Thanks for all the advice, guys! Has anyone tried the StrikeModels 10-degree props as free-wheeling props? I'm considering getting the 35-degree props for the inner shafts and the 10-degree props for the outer shafts... Carl
