Servo Hook Inertia

[Anonymous]

Have any of you guys who use servo re-latchable hooks (ie where there is a servo strapped to the hook) had problems with the larger hook inertia affecting timings of the cruise and bunt ?

I had problems at LH with my servo hook model either pitching up too much or not pitching enough up after launch, irrespective of what I did with the timer settings. I thought it might be hook bounce but now wonder if it is the higher hook inertia keeping the hook forward onto the hook forward microswitch for too long. Mike Fantham had a problem before the ’93 Champs with a model that did the same thing and he fixed it by increasing the rudder tension. Any experiences elsewhere ?

CHE,

In my initial discussion with M&K after I had some success with the relatch hook where I tried to convince them to produce a relatching hook, they cited the increase hook inertia as a problem. My arguements were non-convincing and contrary to thier impluse hook direction.

I have not attributed any of my re-latch problem discribed in an earlier forum string to higher hook interia that would vary the hook swing back timing and hence vary the bunt sequence timing start. I did check my rudder spring tension but can’t give you force number. JIM
