[SIZE= 14px]I was wondering when someone was going to ask so here ya go.
The Release is a simple camover mounted to the hard points where the floats would mount I used a servo box I "STOLE" from JTEC last time i was there .( should have stolen more those things are great)
Now the tow rig. the "mast " was made from 1/2 in aluminum its what i had. its 3 ft tall and there is a weight on the bottom. you want it to balance about 1ft from the bottom -up . I simply drilled 2 holes and used cotter pins to hook the bridle .
To attach the flags the best way was to run a piece of 1/8 in dowl in the seam and simply use zip ties about every 5 inches down the seam. I did that on the leading and trailing edge of each flag to hold them all together .
The tow rope is mini blind cord its cheap and you wont break it . And 1/4 scale is about 80 ft thats what im use.
Take off . This is the fun part lay the banner out in front of the plane for me thats 80 feet i have someone hold the plane go to full power take a deep breath they let go
, i roll about 30 ft climb steep and just before the banner lifts off i level off and change to a shallow climb to prevent a stall " My finger is on the release switch by the way " FLYING . If you're not good at throttle management you will be
. you must be smooth on the controls if you fly too fast the plane will be twitchy as there is some effect on cg if you fly too slow you stall quicker there is a happy speed. when turning add throttle to keep the banner "slinging " to the outside of your turn throttle back on the straights. With some practice it's a lot of fun maybe next weekend i can get better video the take offs are my favorite part. Here is a full scale place for reference. [/SIZE] http://bannertowingequipment.com/
PS: note the original engine oil on the bottom of the plane give it that real bush plane patena
