[RMX:#] Elan trouble

[Currle, Andreas]

Jerry,
I'm pretty sure there is a way to get the weight more to the nose without
adding weight.
Maybe you can move some of the radio gear more to the nose or change the
tailwheel
for a lighter version.
I think that the plane with the 120 and max. 9 lbs will fly pattern very
well.

Subject: [RMX:#] Elan trouble



I have a dilemma and could use some advice from the group.

 

After over a year of building I have nearly completed my Elan which is my
first attempt to build a fiberglass fuse pattern ship.  It is painted,
covered, servos, push rods, and engine (120 four stroke) installed.  Weighs
about 9 lbs.  Looks pretty nice.

 

The trouble is to get it to balance at the CG point on the plan (8" from
wing LE) requires 11 oz in the nose.

 

According to Dick Hansen's plan the weight should be 8 - 10 lbs.  So it is
still within the design range, at ~9.75 lbs.  But even if I can figure a way
to add 11 oz of weight to the nose, I'm afraid the plane will not fly the
pattern well and am having serious doubts completing.  My intentions were to
fly one or two more Sportsman contests with it and then move on to
Intermediate.  Would appreciate some opinions/advice from the group:

 

Should I try to figure out a way to add 11 oz wt. to the nose securely and
finish the plane?

 

Or abandon the ship and move on to something else?

 

TIA

Jerry
