[NSRCA-discussion] Weight

[krishlan fitzsimmons]

Actually Dave, if we could fly large IMAC planes, our airframe cost would go down.  Top of the line 40% IMAC planes cost less than an Oxai.

Jim,

Monoplanes are at 74" span now, and about 900 squares because that is where
the current schedules have pushed the designs to.  The wings don't need to
be any bigger for the 11 lb weight limit.  But at 74" and 900 squares, there
is plenty of room to grow the monoplane bigger if the weight limit is
increased.

The bottom line doesn't change - bigger bipe, bigger monoplane, bigger any
plane will increase costs.

If you think pattern needs more cost and complexity, whether it be biplanes
or monoplanes, submit a proposal.

Regards,

Dave

A monoplane will have higher wing loading. How high is too high?

<96 db, <2M, <11 lbs, and it is legal.  Your challenge is to meet those
specs with whatever equipment you choose.

Raise any of those limits, and the cost and complexity of pattern goes up.
If you think what pattern needs is more cost and complexity, submit the
proposal.  And as Duane notes, the new breed of monoplanes will obsolete
your DA-50 Bipe.

Regards,

Dave

I was thinking pattern legal DA-50.

DA-50's and larger biplanes very common.  Have at it.  :-)

Interesting discussion. I always felt the weight limit replaced the
displacement limit prevent the use of very large engines.

Remove it now and we will see DA-50 or larger biplanes. I have wanted to
build one for a long time.

Bring it on.
