This is worth reading... The comments that follow are also interesting. Basically, the fire was caused by a Skidmark motor. There are essentially two camps - ban all sparkies, and "DON'T ban sparki...

Guys, I have a 5.50" Nike Smoke from PR... Molded, trapezoidal fins, 75mm motor mount, etc. Only ONE available (at least for now), $299. If you have seen the 4" kits --there are ~8 of them in the clu...

I would also like to fly a 54mm shot or two out of that tower, Sean 8) I have a couple of shots in a 100% "stock" KestreL that I want to do @ MHM - A Pro54 K300 and a Pro54 L640. In July, I hope to ...

I was a bit surprised myself - I may even throw in free motor cleanup 😀

This is truly a topic that people have strong feelings about. I really prefer to fly a single altimeter, but everyone must do what they are most comfy with. There are sure times I have flown with 2,...

What size powder charge you using. I will give you a dollar if you do the ground test. 😉 I thought I would use 3 pins. Scott, I used four polystyrene shear pins, each 1/16" diameter on the original ...

I got mine! I was starting to worry just a little bit...
