Atlantic Tug on 12v?
Hey, I picked up an Atlantic tug to use as a retreival boat. I am thinking about running a 12 volt motorcycle battery in it. I will most likely eventually upgrade to a larger prop and not sure a 6 volt system will give me enough power. My other option is running a 2S or 3S lipo and had a bunch of ballast. What do you guys think?

Radio for a Revolt 30
Picked up my first boat, the Revolt 30 rxr, and am mulling through the various radio options. I really like the idea of the DX3S with the telemetry but with the marine RX there is no telemetry. So I am looking at all options. I am slightly leaning towards the Futaba 3PL. Are the Futaba rx's good for boats or is there a marine option? Any other recomendations? Thanks!

But I can tell you, coming from a boomerang myself, that the Boomers can teach you a lot of bad habits that will become maginfied by a scale jet. I would recommend, if you aren't already using it, to set up your Boomerang with a fairly aggressive crow set up so you can start using the throttle more on landing. Boomers are one of the easiest planes I have ever landed. An F-5 is on the other end of the spectrum. Not extremely hard, but much more "jet like" than the Boomers. If you can swing it I would seriously consider the Flash. It's a real nice stepping stone between the Boomerang and a good flying scale jet. You already have the turbine. You could always pull it out later and sell the Flash (you probably won't once you fly one ;-D) but it's an option. Also what size is your field? You'd be surprised how much runway you will use as you are getting some of the scale jets figured out.

[quote]ORIGINAL: Dig it I read post #5 to say exactly that Jeremy. Perhaps the play on the English language is the factor. To myself, and it would appear at least one other, he said exactly that it is a scale jet. Anyway, I digress. Dale [/quote] No where in any of my posts did I ever infer that the Flash was a scale jet. I said the Flash "is a good stepping stone BETWEEN a Boomerang and a good flying scale jet" and I also said the Flash looks like an F-5/F-20. The point I'm trying to make is there is a huge leap going from the Boomerang to any scale jet. And the F-5 tends to run on the higher end of the wing loading spectrum. So I offered the advice of getting some time on an Ultra Flash to make the eventual jump into the F-5 easier. Nothing more. Nothing less.

I find it interesting how many people are having issues with the model stalling. Mine is about as heavy as they come as I have every tank imaginable, smoke, and the monster battery required for the kero start Kingtechs. I set up for slow flight and crawl the model around. Not once has the wing even burbled. I am currently on a trip and won't be home for a couple days but I'll check my CG when I get home. I am sure its located right infront of the main gear legs. The nose wheel is EXTREMELY light as seen in my video when it's taxiing.

RE: C-ARF Ultra Flash build Thread + Video
[quote]ORIGINAL: Beavis IFlyEm, Thank you for the expansion and helpful pictures. Expanding on my previous note as well, correct me if I’m wrong, but it appears that basically what you are saying is that a more forward CG increases the load factor. As you probably know better than me, load factor is a well-established variable defined as: n = L/W, where: n = load factor L = lift W = weight It is also well established that the load factor affects stall speed through the formula: Vst = Vs √n, where: Vst = stall speed Vs = stall speed in straight, level flight √n = square root of the load factor This is also why the stall speed increases during high load maneuvers, such as high bank turns and certain aerobatic moves. Wow, look at all that math in RCU! [/quote] Load Factor is the ratio of Lift to Weight. Essentially it is a G-Force. So in straight and level unaccelrated flight the load factor is +1. So if the weight goes up the lift needs to be increased. But doesn't directly indicate an increase in load factor. As long as they are equal the load factor is +1. Load Factor increases as you increase lift. I.E. if you develop 4000lb of lift and the craft weighs 2000 lbs you are acheiving a load factor of +2.0. When pulling out of a dive or a tight turn and you have an accelerated stall it is when the lift (created by AOA) exceeds the Critical AOA and a stall is achieved.

[/quote] I'm writing from my phone so I'll give you the Cliff's Notes version and update it once I get to a computer. You are correct. Weight affects stall speed. Your CG is in front on your center of lift. This is why the nose drops when the wing stalls. So when in normal flight, to offset the nose dropping the tail produces a tail down force. This force adds to the overall weight the wings need to support. So move the CG forward and an increased tail down force is required to offset it. This results in the higher wing loading and increased stall speed.

Microz, 50cc generally will have a span on the mid 80 inches. However, if you get plug in wings you have 2 wing panels in the 3' range. IMO the best flying 50cc airplane available is the EF Yak.
