Participation

[Doug Cronkhite]

With the new batteries I saw yesterday.. weight will no longer be an issue.

Yes-- you can weigh the airplane without the electrons (uncharged), but the
fuel container (battery) must be installed. Not going to help much.

Randy + Norm,
 I've seen it written as: 
"4.3. Weight and Size. No model may weigh
 
more than five (5) kilograms (11 pounds) gross, but

excluding fuel, ready for takeoff. No model may

have a wingspan or total length longer than two (2)

meters (78.74 inches)."

If you consider a battery as the "fuel" for an electric plane... Just a
thought.

I think electric are weighted without the pack.  At least I have seen it
written on this list that way/

Just some thoughts from an electric flyer that hasn't started in 
Pattern yet.  I have flown electric power in IMAC, but am 
interested in Pattern because of the 2-meter size limit.  My IMAC 
plane, a 2-meter Staudacher which weighs just over 13 lbs. RTF, 
and is as large as I want to go.  In larger electrics the price 
starts going up exponentially, but 2-meters start looking rather 
small alongside of the now typical IMAC planes.

BTW, my battery pack weighs just under 3 lbs. so if the rules were 
ever changed to allow electrics to be weighed without the pack, 
I'd only be at about 10 lbs.  Not too bad for a plane that was 
originally built and flown with a Quadra gas engine.

Anyway, the point of all this is that you might be able to start 
attracting some electric powered flyers that want to compete 
simply because of the 2-meter limit on size.  I know it's not 
something that's going to happen overnight, but changing the rule 
about weighing with the battery installed would surely help.  I 
also know that some of the top rung people are already flying 
electric pattern, but with state of the art planes that's hard for 
entry level builders to achieve.

I've been trying to decide on a pattern plane to build for some 
weeks now.  I'd like it to be a 2-meter if for no other reason 
than my eyesight isn't very good and the larger planes are easier 
to see.  Thinking of building a Typhoon 2K with Mike Hester's 
modifications, but the project looks daunting to someone who's 
never built a wing with tubes, adjustable wing and stabs, etc. 
Also have been considering the Focus II, but figure it will be 
overweight with the batteries.

Oh well, that's my input for today.

Norm: Because most pattern enthusiasts fly glow powered models, there really
hasn't been much discussion or concern regarding how glow/gas/electric
pattern aircraft are weighed.  Competition rules should be as fair as
possible when applied across the board to all the different types of models
authorized to compete in a given category.  Rather than weigh electric
pattern ships without batteries, it's my personal view that either 1) the
weight limit for pattern should be eliminated, or 2) weigh all aircraft
types  -- gas, glow, or electric -- ready to fly....with fuel or batteries
as the case may be.  I'm not pro or con any particular type of power plant.
I've used glow engines for nearly 55 years and currently have two electric
pattern ships on the workbench.  Our AMA competition rules are guided and
influenced by international FAI rules and it will be interesting to see how
this issue is handled as more and more modelers move to forms of power other
than glow fuel.
