Ron, you will be fine wiring two e-matches into the same output on the timer.Art

Ron,If you’re using ematches (or especially Cessaronis), one timer will easily light them. The PF timer can handle more amps than you can supply with a hefty battery pack. I plan on lighting 6 24mm with one. Probably going to…   Read more»

If I want to use a PerfectFlite Minitimer or Xavien timer, can I use a single timer for two motors or do I need two timers?Ron

I like the PET2 but as an alternative you may wish to consider Xavienhttp://www.xavien.com/Doug

I built the lower timer bay in mine to hold either the Missileworks PET2 timer (ultra-reliable I’ve heard, and two separate timers in one) or two of the PerfectFlite Minitimers (Ultra-high current capable, tiny, cheap, and reliable).Since I just got…   Read more»

so for the little stuff (ie, estes rockets), you think the elmers will be fine for filling in balsa fins, and those annoying spirals on the tubes? thanks for all the input!

For balsa fins Elmer’s and sandable primer work great. No need to spend the extra dollars.But for those odd occaisions when you need a little more, I like that Hobbytown stuff. It has the consistancy of spreadable margarine. For bigger…   Read more»

I found some filler at Hobbytown that is really good stuff. A bit expensive but well worth it. I seem to recal is was 7 ot 8 bucks a jar. I like it a lot better that Elmers. It is…   Read more»

The Rocketry Forum. http://www.rocketryforum.com/From my view, it’s the online forum with the most traffic, more so than rocketry online.Lots of good info and decent folks.-Ken

I use the body putty glaze filler. Comes in a small tube, it’s easy to work with and sands easily. It’s great for wood fins.Ken.

You’ll get a thousand different replies on this. You can search TRF, but the easy answer I have is:Elmer’s Fill-n-finish (available at Lowes) thinned with water. Brush on both sides of the fin (before attaching to rocket) and clamp with…   Read more»

When I’ve done Aerosleeve tubes (or hand lay-ups for that matter), I generally wrap with peel ply and then breather, then either vacuum bag it (big chance of wrinkles until you get the touch for doing the bag) or if…   Read more»

The first time I used Aerosleeves, I wrapped the tube with peel ply and then taped it as Conway suggests. The sleeve compressed really well and all of the excess epoxy was absorbed by the peel ply. The tube turned…   Read more»

I have also seen where glass is laid dry over a tube, and then a woman’s nylon stocking is stretched over the assembly, pulled tight and knotted on both ends. The epoxy then gets painted over the whole works. When…   Read more»

With the Aerosleeves I do this to get it nice and tight to the airframe. You need two sturdy posts (I used my fence posts on a corner) ratchet tie down strap and two 3/8″ pieces of cord about 5’…   Read more»

Ive tried that and it can cause an uneven gel coat. It has always worked best when going from one end and evenly pushing the epoxy one direction. The other reason is we want to squeeze of the excess so…   Read more»

Conway, what would you think about wrapping the tube from the center out – one side first, then the other?

Well, all have mine done before then, but I’d still be interested in seeing a live demo. Called Ft. Collins Plastics today and they are sending the mylar to my home. Shipping is much cheaper than driving up there. Hope…   Read more»
