A Three Function Modification of the Texas Mini Timer
This is another example of when we do not have a product to fit a customer's needs, he modifies one to do it. Tony Robertson of Sandy, UT sent us this neat and novel application of one of our oldest products - the Texas Mini timer.
This example is a new 340 sq. inch F1J model powered by an AME .061engine. Tony expects the model to be very competitive with those using higher powered (and much more costly) engines and more exotic timers as a result of weight savings, due in part to use of the Mini timer. He has flown earlier models with the AME and Mini quite successfully for several years.
As shown in the photo below, Tony has removed the start/stop wire from the faceplate bracket and replaced it with a wire that rides under the main disk and is released by a separate slot in the disk. In this application, the top wire that was formerly the "Quick DT" is now used for bunt. The new wire at the bottom is used to move the stabilizer into the glide position and to set the rudder to turn.
DT is not shown in the photo, but is accomplished with the conventional fuse.
The engine shut off is conventional using the Texas RPO and existing release wire on the timer.
Tony has made his own "start on release" switch from one used before on an F1B model. It works much in the same way as the new product being developed by us. Tony says he feel ours will be better than what he is using now.
The "V" shape in the wires allow for a certain amount of adjustment to be made to the timing by altering the bend. Note, that he had to know about where he wanted to cut the new slot in the disk as the amount of adjustment by changing the wire shape is limited to a second or two.
