Bat Wing Lifting & Closing Ideas

Crap, I'm allergic to cats. Otherwise I would do this for sure. ;D

I want to apologize to everyone here for my misleading diagram on to how to make an effective batwing drive. I don’t know what I was thinking.
There were some here who knew immediately that I was way off base and called me out on that. Murci-me recognized the system I proposed was really “Rube Goldberg”. That was very perceptive.
So I considered again the problem of how to make the batwings move with an eye on simplicity. I think I “hit it” this time.
Please review this revised method and maybe someone can incorporate it into their build.
Thanks again for your patience with this issue.

Here is an explanation of how it works:
“A” Pull string on dash
“B” Cat is released from cage
“C” Mouse sees cat and runs up tube which tilts and releases golf ball
“D” Golf ball rolls down ramp and lands on lever on bucket of water
“E” Bucket tips pouring water through funnel into tank
“F” Tank fills causing float to rise with linkage releasing bowling ball
“G” Bowling ball pushes swing arm with match and lights candle
“H” Candle burns through string, releases hammer, strikes button switch
“I” Fan blows ship across water
“J” Ship hits barrel rolling it down ramp
“K” Barrel starts domino effect
“L” Domino hits meat cleaver and cuts string
“M” Cut string releases weight, pulling string
“N” String pull levers pushing up batwings
String:
As input of ideas , I purchased 4 x satellite dish actuators which were new ( but cheap) and they have had to be shortened for purpose but otherwise the microswitches inside are fully adjustable for stops at each end of travel ( about 50mm) ,and being 30v are then the perfect speed of travel.

I agree there are a number of different ways to do the Bat Wings. The system on Dratt's car is fairly simple, it uses 2 88 Fiero headlight motors one for each wing, The control module needs power and a ground and a signal to move. I wired the system into the relay box for the engine and have a relay controlled by the ECM (a ground) and also wired to a switch in the cockpit to provide the same ground. Thus the Bat wings are controlled by the ECM and can be over ridden by the switch in the cockpit. The nice thing about the motors and controller is there are no limit switches, the controller uses current limiting to shut down the motors in either direction. The same controller and motors are used in the late 80's Firebird.

What is the feedback you are talking about? The only feedback a LA can provide is in a POT, which can either be a 2 wire or 3 wire system, both of which work identically the same. I'm pretty sure this is a 3 wire feedback actuator. If its not, the are hundreds of them available on Ebay and elsewhere that will suit your needs in the $50-$60 price range.

I believe the bat wing motor I will use are here. http://www.rcgroups.com/forums/showthread.php?t=1527522
I don't think a tenth of a possible 10th second difference with the bat wings opening will make a difference to me.
ServoCity carries a great selection of quality linear actuators and linear servos. Our new Heavy-Duty & Super-Duty Linear Actuators are perfect for both hobby and industrial applications and come in a variety of stroke lengths and speeds.
