Glued at both ends and a spot or two down in the fuse where it touched the fuse sides and bottom. No issues at all, all my speedies are that way.

I see, is that bell cranked the other end up to the T tail or snaked curved?

Do you silcone your servo in or mount with screw using adaptor on servo?

I guess that method would keep the cg forward a bit too...I find I have to stuff half the battery under the ESC in the front to maintain proper CG, with my elevator servo being in the back.

Good point. Isn't the rough rule of thumb for every 1 in the back you need 4 in the front.

No, the sound that it makes is what makes the Banditos awesome... I don't even have to fly it to have everyone come see what's going on...

Evan, thank you for the good info. Question, regarding the Cyclone, where can I find information on it? Dive or no dive, 229 mph is stinkin FAST! Yes, unless one can reduce drag a lot, the Demon and Dust designs are probably limited to 140-160 on electric power unless one can shoe-horn in a lot of batteries and a big motor and esc.

Regarding full power for the entire flight (electric powered that is) at speeds of say 150+ (mph) it is just hard for elec to compete with gas/glow. With the gas/glow, larger tank = longer flight. With elec if you are running at 20C (20 x capacity discharge rate) 3 minutes (approx) and your done. At 30C expect a 2 minute flight (or slightly less). Fly at 40C and your done in about 1.5 minutes. So.....the lower your discharge rate the longer you can fly at a SLOWER speed......urghhhh!!!!! All this being said, electric has improved a lot in the last 5 years! Looking forward to the next five!

Cyclone- http://acmeflyingmachines.homestead.com/cyclone.html

It's a good plane. Built in the U.S., maybe not as finished as the euro planes but comes with the wing servos prebuilt in the wings and flys very well. He'll also do about any color scheme you want.

Why would electric power be limited to 140-160 MPH on a Demon? A stock .45 will make one do 150 mph.
If electric power can't make one of these planes do 200 mph, that's pretty lame.

I agree with combatpig, I would recomend a neu 1115 1.5 y motor on 5s 3200 30 to 40c lipos, a castle Ice 75 amp controller and an apc 5.5 x 5.5 prop. This setup pulls only 55 to 60 amps does close to 200 in an f5d plane and should do close to 170 in a demon. Proper airflow over the motor and controller is all thats needed for cooling. This is what I would use.

There is so much difference between a F5D and a Dust or Demon it's not funny. Look at it the other way and would you recommend a Dust set up on a F5D? A good Dust set up would be a .50 with a 8x8 prop. Totally out of place on a F5D...

A 1115 and 5.5x5.5 would probably not get a Dust in the air and if it did it wouldn't be over 100. A Dust would need a 600 size motor, in fact a 600 Helo motor and a 8x7 would be a good start, and fairly cheap.

And a 5.5x5.5 on a 1115 and 5S is no where near 200, maybe 150-160.

I don't know anything about electric setups, but a Demon / Dust can hit 200 mph on glow power.
This leads me to believe that there must be an electric setup that will do more.
Imagine how much less cowling there is to deal with, pipes hanging out, etc..

Dunno CP, There could easily be enough batteries stuffed in that thin wing to amount to a Nitro burner and pipe to hit 2 bills.
200 aint easy for anyone regardless of power system.

OK I had the wrong plane in my head. Go with a Neu 1515 2y and 9s and a 7 x 7 prop. That should get you close to what your after.
