There have been a few threads recently that got me to thinking that perhaps I should put together an article on my L3 project. This project was an all-composite build with a number of features that I hadn’t seen anyone…   Read more»

What method do you guys prefer for high performance designs of 4″ diameter or more? My preferred method is to use a kevlar strap and epoxy each end on opposite sides of the motor mount tube. The strap is long…   Read more»

Anyone tried one of these? Am I properly understanding that this creates a vacuum from my air compressor?http://www.fibreglast.com/product/Vacuum_Bagging_Starter_Kit_02229_A/Vacuum_Bagging_Pumps

Staying along the lines of my research for a L3 project, I have been looking at motor options. Why is it that 98mm reloads are so much more expensive than an equivlent 75mm load? For example, the Pro75 6 grain…   Read more»

I hope this is the right forum for a build thread.I was lucky enough to get a KestreL from John awhile back. I’ve had it for a few months and have read the instructions a few times and thought about…   Read more»

For those of you that use rocksim, do you just use the default numbers? I have found that for some of the L3 designs I am looking at the difference between the default numbers and checking the “calculate Cd at…   Read more»

Does anyone have a Rocksim design for the stock PR Intimidator 5? I’m thinking about using it as the base for my L3 and I’ like to play with it a bit. Thanks.

Just curious how many might be headed out to the Atlas site this next weekend? Obviously Mother Nature bats last and she may keep us all away… if the forecast is accurate (45 and partly cloudy) I’m curious who might…   Read more»
