Dremel and make a new Sail Servo mount to install on the factory radio tray. Remove the battery switch for more room, and replace with a magnetic switch that can be turned on/off without removing the hatch.

I am thinking since the Tactic Radio appears to be made by Futaba, they must have used the S3802 (or old S125) as the Sail Winch servo. It looks to have the same size and spec as the Tactic TSX382 at 6v. If it is, then the Sail Servo on 4.8v is only 122 oz inches. Not much grunt to haul in Main/Jib full of moderate (8-12mph) wind.

Hitec HS-765 offers 140* travel 152ozin torque @4.8v/183@6v
Length 2.32in (59mm)
width 1.14in (29mm)
height 1.96in (50mm)

Hitec HS-815 offers 140* travel 275ozin torque @4.8v/343@6v
Length 2.59in
Width 1.18in
Height 2.26in

Futaba S3802 offers capable of 140* travel
Length: 1.7" (1-3/4") (44mm)
Width: 0.9" (7/8") (23mm)
Height: 1.7" (1-11/16") (43mm)
Torque: 122 oz-in @ 4.8V - 153 oz-in @ 6V (6v spec as quoted for Vela)
