I am going to put a glider tow hook on my EXPERIMENTAL Smith Cub. I was thinking of connecting the tow cable to the flap cable after it goes around the bottom pulley in a Y type configuration. This would put the tow release on the flap handle so that when you pulled flaps you would also release the hook.
Thoughts
1 - I will always be towing at fairly slow speeds, less than 60 mph so yanking the flaps should not be a problem.
2 - If the whole thing failed it is not a primary flight control, (the flaps fail up) so worst case would be a no flap landing.
3 - simplifies controls, installation, cockpit clutter and weight.
4 - It would be set so that you could tow with 1 notch of flaps and the release would not activate until more than 1 notch of flap were pulled.
O.K. My flame suit is on so tell me all the bad things about this that I am overlooking. Remember....this is an Experimental airplane, so I can experiment and try new ideas. I just would like to use all the knowledge available before I try a DUMB idea.
Thanks
