This is the Sig 4*40 built with a B50 11XL
Hacker Motor geared 5.2-1, Hacker Master 30 cell 48 amp ESC, 15x10 APC-E prop, 4
Hitec HS-85BB servos, Hitec SuperSlim receiver, 550mh receiver battery, and 24
3000nimh cell flight pack. The all up weight can in
at 108oz to give me 100 watts per pound.
|
This is all of the wood that was either replace or
removed from this kit. |
 |
|
This is the replacement wood, a 6.9oz savings. |
 |
| I pushed the elevator and rudder servos back into the tail
to make room for the flight pack. |
 |
|
I am using Hitec HS-85BB micro servos to save weight. |
 |
|
The wing is a quick build with standard construction. |
 |
|
The only thing I changed with the wing is to move the
servos out into the 4th rib bay and open small holes for the wires to go
through. |
 |
|
Before I glue the top turtle deck on I add a light ply
rail. The front of the battery will be secured to this rail with Velcro. |
 |
|
To make the battery hatch I glue the turtle deck from F1
to the firewall and from F2 back. I then make a hatch to fill the
gap. |
 |
|
The fuse is only 8.3oz ready for covering with motor mount and 2
servos installed. |
 |
| Everything ready for covering. |
 |
| Close up shot of the motor. I am pushing my luck by using
the SonicTronic motor mount but it has worked so well for me in the past
an weighs next to nothing. |
 |
| 24 cells is way overkill for this plane but I wanted a plane
that could give me 10+ minutes of great performance and all though the wing
loading is a little high this plane handles it well. |
