Two meters would likely be competitive with 3M ships?
Just ask Bobby McGowan if two meter ships are competitive right now with 3M
ships.

have to say Bobbys two meter

I think the answer would be yes and I think DP
would even have to say Bobbys two meter is reasonably competitive with 3meter,
even larger than 3 meter
H Marta Can you give a little more detail to a 2m fan?CheersDavid [Aeroplane] LeighOn 13/08/2006, at 2:40 PM, Marta Zavala wrote:Two meters would likely be competitive with 3M ships? Just ask Bobby McGowan if two meter ships are competitive right now with 3M ships.I think the answer would be yes
Daryl,
Can I recommend a simple name, 2D. I'm sure there was a double D
girl is in the past. Of course if you've hung around Southern Calif
maybe 2M is not outta the question. :-)

I've written on this topic before, but I think it might be good to repeat it.
The reason that most 2m gliders fly like crap (quoting one CRRC flier),
is that they are WAY too heavy for their span. Consider a log-log plot
of weight versus span. The following three points lie roughly

If we were all launching on 12v winches with correspondingly lighter lines,
the light 2m gliders would likely be competitive with the 3m ships,
because the 2m ships would launch higher. Their maneuverability
and lower speeds on landing is another advantage.
Be careful launching the Allegro - it has a weakness that I've seen and
heard of from a couple flyers: it's not winchproof when faced with
negative G's.
Just wanted to put that out there before you end up like me (currently
finishing up rebuilding my Allegro's center section).

Mine isn't built-up, it's composite. I've been launching the hell out of it for

Dave,
What a great post. Thank you. You're right on about
the MH32 being a poor choice for a 2M section. I don't
like it for open class TD either. Drela has done a
good deal of optimization on sections for us, and he's
got a pretty good idea of what works in the real
world. Definitely a good idea
I noticed a 2M with Drela Derivative airfoils at Sal's site:

Has anyone seen it in person yet? Looks promising.

At last! An interesting discussion. Reminds me of the good old days
or RCSE from about 10 years ago. I have a notebook full of posts
about stability and control from1995 to1998. Lots more interesting
than what happened, or didn't happen, at the latest contest. I had a
lot of success
If I want a challenge, I fly F3b. 2M is nonexistant on the east coast.
As long as they stick 2M in the middle of the week, I'll fly it to pass
the time.
I'd rather see 2 days of RES than 2M.

Looks pretty ugly to me. A small fin in front of a huge stab. They
should have done it the other way around.
