Re: Rg65 - "DIRTY DEEDS" If you think that's tiny, try a radio installation in the following:...
I suspect you can save some dough by picking up a used 75mhz radio, even if it has lots of bells and whistles. At least this is true in the rc...
I think you're mixing up some things here. That's an interesting article, but I think its main relevance to sailing footies is the manner in which...
Obviously, he used a very small aperture (high f-stop number) to get a lot of depth of field. The child is much further away. I did a double take...
BTW, half a meter is about 20 inches.
As I recall, there are Yahoo groups for Xfoil and Profili. Google Javafoil and you can find that program, which is handy for coming up with...
Using Profili (which is an easier way of using Xfoil), I looked at a NACA 0012 pivoted at 35 percent of chord as you say. Looks ok if turbulated,...
Keep in mind that the Reynolds number on that c-class cat is likely to be several times higher, which may mean that some other solution would be...
P.S. Above is somewhat theoretical. I'm an engineering type, and I fly model planes, but I haven't built my wing sail model yet. Obviously I've...
Sorry if this appears more than once. The web site is giving me a hard time, as it sometimes does if I take very long replying. I am not entirely...
IF your winches are powerful, you may want to measure how much currrent they draw and compare that to the current rating for the BEC. I know in...
Re: Speed Runs Earlier in this thread, someone claimed that some of the boats were displacement hulls. I wouldn't really call it "displacement"...
A guy I know has tried the 4 channel and the 6 channel and likes them for some of his rc sailboats. Note also the "DIY" conversion kit from...
Come to think of it, I might have got the link over at the Yahoo group instead of here. Still, I think that it's pretty likely to be legit here too.
If you're melting lead, a good source is used wheel weights from a junkyard or garage. They might just give them to you, and it's my understanding...
Yup. I'll bet you got a lot of questions about your boat, too. That's a pretty busy area. The four wheels you'd need are a bike and a trailer....
I downloaded it yesterday. Maybe there's something bad in there, but what I saw was all RG65 stuff, including a lot of plans, some newsletters,...
Kind of fun, both of them. I lived within a few blocks of the reflecting pool for years, but I don't think I ever saw a sailboat model on it. In...
Profili allows you to put in the correct Reynolds number. I am not aware of any "increased drag" not covered by that. Cl (coefficient of lift) and...
I've been poking about with Profili on this issue. It looks to me like the optimal technique, at least for the smaller boats, is to use a thin...
