Tomy Timer Mounting Modification

We are working to improve the reliability of the tomy timer. One of the things we are trying to improve is the way its mounted in the parachute modules. The back of the timer has lots of holes in it, and getting even the smallest bit of glue on one of these slows up or completely stops the timer. To correct it we have to remove it and jab at the small holes with a needle to free the glue up to get it moving again.

Another downside of putting glue on the back of the timer is that you can only use a little bit in the places where there are no small holes, and it doesn’t take much to break off from the mounting on a crash or heavy landing.

One method we are looking at is using the timer mount that comes with the toy itself. This in effect is the base of the toy, but it provides a clip mechanism and is molded to keep the timer in the right place. Here is a pic with just the top of the toy removed.

The idea is to mount this timer holder to the parachute module structure instead of the actual timer, then the timer sits quite sturdily inside the holder and clips in with the two clips that wrap around it.

To get a good attachment the little side wings are removed with a sharp knife (carefully) and sanded smooth. This provides the entire surface area of the edge of the holder to be stuck to the structure. Here is the side after being sanded

Here is the tomy timer with the wheels removed and the winder attached placed in the holder.

Once I have it mounted in the parachute module I will add some pics here
