Hi Bob,

I see the best part of electric for one of these planes is that you have
a pretty high level of confidence the motor is going to run when you
hand launch, then bring it down for you high-alpha or 3D flying.  With a
little glow motor, you need to ensure it is broken in nicely, and is
tuned nicely.  So, there is a little more of a threat to a crash using a
smaller glow engine - until its broke in and reliable anyway.  That is
my only worry.  With a decent exhaust deflector, clean up is limited to
he very tail of the plane.  I just don't like charging flight packs for
now.  

I think I'll look at this electric again with the batteries like the
A123 cells are weaponized - I mean hobby-ized :-) .  There is a good
thread on flying giants about these cells being used for giant scale
receiver packs now.

Thanks,

Jim W.

Jim,

A couple of years ago I would have agreed with you. Glow was a known for
me, electric wasn't. But for the smaller planes I will probably never go
glow again, electric is just too easy. But, yes, there is a learning
curve and up-front expenses going that route. Once you have 2 or 3
planes with similar setups, the batteries can all be shared (I have a
lot of 2100 3S packs and associated planes). 

I have a Vanquish and a 3DHS Aspera which I both love. I think going
glow would not improve the flying any, and the associated cleanup of
glow would take some of the fun away from it, JMHO.

I would love to see the glow setup fly, though.

	Yes, I knew it would draw some ire..

	I kind of detest electric stuff - for a while longer anyway -
I'm still in mourning over my 2006 nats e-meltdown :) I'm one of the few
pattern pilots who went electric and said "no-thanks" after spending
their way through it.  I really do not want to buy $50-$80 battery
packs, when I'm carrying 30% heli fuel everywhere I go.  

	I have a little bit of experience in this.  I have an Extreme
Flight Mini 3-D with a GMS .32 that absolutely screems and has great
throttle response.  The GMS .32 swings APC 11x3 at 13,100 rpms as
measured this weekend.  The vertical speed on this plane is incredible,
yet with about 15 degrees of flaps it will almost hang in ground effect
and lower vertically for landing.  This little plane garners a lot more
excitement at the local club than my 2M planes.  Maximum fun, minimum
investment :) 

	Is this experience a fluke? Is the cheapest motor you can buy
ever going to be good enough????  Would I ever buy another one that ran
as good as the first????

	I took the Extreme Flight E-Extra 300 and converted it to a GMS
.32, this time buying the luxious 'remote' needle valve version.  After
lining everything up, I also used an OS muffler extension to get the
muffler futher away from the plane.  This plane came out just about
exactly weight wise to the electric versions which fly on 3S packs -
worse-case 1.5 oz heavier.  I installed the rudder servo in the tail.  I
also used Futaba 3101 and 3102 servos, which are larger that whats
called for.  The result?  This plane flys amazingly well!  Vertical
speed is so fast that it will just make you belly laugh!  It is fun as
heck, and like all the EF planes, flies much "bigger" than it is - cool
success so far.  It is a shock to see landings for a plane this size,
slow, float, and land, where as even many other electric small planes
get to a point where they just "drop" out of the air.  This one is
way-cool.

	Thinking about the Vanquish, and the way-overpowered flight
characteristics of the Mini 3D and the E - I mean G-Extra 300, I figure
the same motor package on this slightly bigger airplane will do just
fine.  Also, the Vanquish flies on a 4 S pack which weighs about the
same as the GMS .32 in itself.  Actually, I'm figuring that a
G-conversion would come out lighter than the E-versions. In all
actuality, the fuel proofing has been minimal.  

	Here is an agregious non-sponsored plug!  BUY EXTREME FLIGHT R/C
STUFF!!!!!!!!!!  Any plane, any thread you'll read, exemplifies the
product, service, and flying qualities.  These little planes fly very
very well and I'm much happier with them than a foamie type plane.
Plus, you can fly the Mini-3D and G-Extra 300 in a park.

	I do see the benefits of leaving it electric though, and Cameron
sent me an email saying I could fly his at this contest.  I'll go for a
flight and see.  I'm still leaning towards another GMS .32 or possible a
Webra .32 though :) If you do a weight veruss HP study on all the .25-
.30 class motors, the GMS and Webra stand out as the biggest bang for
the weight.  Hey - this stuff is about modeling and having fun right?

	Thanks,

	Jim W.
