Building the Schuler 1:3 ASH 26

| Retract and R/C Equipment Install |

This is a HOCK retract, it has a shock absorber, and brake. The unit comes with
brackets that mount to the frame for retract and brake servos. You also can select
different diameter and types of wheels.

When I ordered my 26 from Reinhard, I had him install the retract, so the bulkheads
came installed with the retract.
|
 |
As you can see the retract assembly fits quite nicely. Two allen head bolts hold
the unit in place. The bottom of the shock mounts to the two aluminum struts with
a small bolt.

Here the R/C gear is in place. I try to keep things tidy by using mini ties with
a self stick anchor pad that's 1/2" square, you can get them at your local electronics
store.
Also you can see were I cut down and widened the notch in top edge of the
main retract bulkhead so the seat fits properly, look at the photo above. |

This shot shows the location of the battery packs. They fit forward and under
each side of the flat portion of the seat pan. The square portion of the seat pan
makes for a great location to fit removable ballast weights. I used some flat
3 oz. fishing weights. There held in place with a 1/4" nylon bolt that fits through holes drilled in the weights with a "T" nut on the bottom weight. Simple a fast to adjust
your ballast. |

Here the tow release servo, switches and battery backup unit are installed.
The tow release is connected to the servo with a simple throttle cable, the servo
arm is in the up position and it lines up inside the square portion of the seat pan.
The batteries are held in with Velcro that's mounted to flat pieces of plywood
epoxyed to the bottom of the fuselage. I used two 5 cell 2000 mh with a voltage
regulator set a 5.2 volts.
