B727 w/ 3 EDF-50s

Here are some pics of my latest. I started a thread in the Foamies section under B757 conversions, seeing how this used to be the 757 glider from LifeLike.







Fanman, btw I'm not competing with you and your 727 project. I
just have loved the 727 my entire life and had to try and see if a
B757 glider conversion would work.

Painted the wings and engine exhausts silver. Used lightweight
spackle and reshaped the nose (along with lots of sanding).
Looks much better than the previous pics! Going to paint it the
old Delta colors.

Can't wait to see finished product. Because RCFLYINs DC-10 flew
so well with 3 EDF-50s including ROG, I'm pretty excited about
this one.

Btw, since the weight of the plane and fans is 9 ozs, if I hot wire
it in half just in front of the wing and hollow out the fuselage,
how much weight do you guys think I'd save? Just wondering if
it's worth it or not, to disrupt the structural integrity by having to
glue it back together.

Pretty quick builder, eh Hawker???

I love the 3 holer too!

How sturdy is the fanfold tail? It looks like it may be brittle. Have you considered a little carbon fiber ribbon re-inforcement? You can get it at most LHS's, weighs very little, can be glued to foam with odorless CA. Only problem is it's black, if your tail is gonna be white, the black will always look darker under the paint.

What do you draw on all 3 motors (amps)? What battery pack?

Eddie,

Yeah, quick builder

I'm considering my options for carbon fiber and the other day
while at the LHS I forgot to ask about it!! I will though later this
week. I just ordered several different packs and will see what
does the best for it. They arrived today (wife called my work) so
later on tonight I'll try them out.

Hopefully it'll be a great little flyer. Can't wait to get it all
painted up in Delta colors (the old triangle type with all black
nose). You can see pics of that scheme on www.airliners.net

Here are all the packs I have to choose from for now...

6 cell 7.2V/600mAh NiCad (GWS pack)
6 cell 7.2V/270mAh NiCad (GWS pack)
7 cell 8.4V/350mAh NiCad x 2 packs (GWS packs)

6 cell 7.2V/1600mAh NiMH (AA)
8 cell 9.6V/1600mAh NiMH (AA)

and a monster
8 cell 9.6V Sub C 2400 SCR NiCad stick (much larger than I
imagined it would be!) 1 lb 1 1/8 oz!!

I'm most likely going to use it for my twin EDF-75s (my 2nd one
arrived today - another 4-blade). If the B727 flys well I may
make a large DC-9/B717, or an Airbus (not sure which model
yet, but one of the two engine versions). I bought a ICS-600
ESC (30A continuous, 45 peak) that will control them. More than
enough I think.

What would you all recommend I use with the 3 EDF-50s in the
727? If it's not listed above then I'll look into it.
