Slow Progress

Progress has been slow this last 2 weeks, or maybe the weeks just went past a lot quicker than usual :)

We have been working on building 3 wrockets to take to our next launch day. A one bottle wrocket a 2 bottle wrocket and a 3 bottle wrocket. I want all the wrocket to have at least 1 parachute. The single bottle will have a main chute module, the 2 bottle will have a main chute module as well as a drogue chute module and the three bottle will have a main chute module as well as a drogue chute module. Hopefully this way we can get some more testing done on the dual chute setup.

PL Glued Chute Structures
The additional wrockets have meant building additional modules which is in progress. These new corrugated cardboard structures have all been glued with PL Premium instead of my usual metal pins method.

I haven’t put the elastic bands on them yet for the pressure plate, but the sides seem fairly strong. Here are some pics

My PL gluing skills need a bit of work but the second one was better than the first one.
Here is a drogue chute module structure

Fin Fix
After the last launch day we had a fin come loose. I decided to remove the metal pins and glue the fins to the RFA. These seem very solid now. Ready to fly again.

The side attachments as well as the spine of the fin itself is glued to the bottle.

New Timer Mounting
As we have a new method of mounting the Tomy timers, we had to order some more, 5 arrived today .. so these will be put to good use in the chute modules with both the timer and the mount itself being used. The rest unfortunately, goes in the bin :(
