Rich, I’ve built birds that weigh over 20# and have NO drogue. They just break apart at the ebay joint and deploy a long shock cord and fall from apogee without any drogue whatsoever. You’ll find guys like John Wilke…   Read more»

Shredder, just about every dual deploy L2 and L3 bird I’ve ever seen deploys apogee out of the middle of the airframe and main out the nose. There are a variety of reasons for this:1- When you break in the…   Read more»

I have a 4″ fin can/booster that survived impact from 8000’+ – built with West Systems. It has flown since multiple times with a new forward airframe and nose.

way geeky set of posts… way awesome motor. What I’d like to see is something like a 4″ version of the motor Dr. J is building for us…. bet it would beat 330K.W

Ken is close to right on…. but I can’t say how close. Besides, it is something so different from your experience that just saying 99% L in an 54mm case doesn’t even come close to the reality. Just imagine an…   Read more»

Believe it or not, I was just looking at UnLeashed the other day thinking it was time to do the strakes and start thinking about filling and wet sanding the whole thing. Hopefully, I’d be able to go to BALLS…   Read more»

Yes you can join onsite – see Joe Hinton. You can also cert up to L2 via Joe or if you are cert’d via NAR, then those certs are reciprocal.Snow falling in Lyons, outside temp is 34 degrees. I’m going…   Read more»

Dave is most certainly correct. The rules were changed 2 years ago. You don’t need to be certified, you just need to be a Tripoli member. Of course you can only fly to your certification level. non-cert- up to G,…   Read more»

Not to be divisive, but NAR did everything they could to kill HPR (G & above) before they realized they had to get on board. NOTHING they have ever done since has done anything to advance HPR other than to…   Read more»

Adrian, McGuckins in Boulder has #2, #4 and #6 nylon screws

The discussion on when to hold Oktoberfest has been ongoing for years. We had a similar weather experience in 2006 as I recall and we pushed it up to the 1st weekend in October. However, BALLS then got moved later,…   Read more»

OK, no Hypertek K. By the way Ed, it is the 54/835cc tank and uses the J grain with a smaller orifice.

I was actually planning on trying to fly a Hypertek K this time around, so I would appreciate the Hypertek stuff being in the trailer.

I hope I can be there to see this baby fly. Well done and very well documented Ed.

OK. No surgery this week – I’ll be out to Oktoberfest Friday and Saturday and I may even fly an M.Warren

Ed, you probably did press Save. However, I probably overwrote it – I didn’t even pay attention. For at least the last 5 years I’ve traditionally taken the Saturday morning to early afternoon shifts – weather and fire ban permitting…   Read more»

I claimed my standard Saturday 8AM-2PM LCO shifts as usual, however I should put a warning out there – I may have to go in for shoulder surgery (rotator cuff, SLAP) the week of O-fest. MRI this Friday so will…   Read more»

Congratulations Tim!!!!

Bob, you can’t do anything on the inside surface of the closure – you wouldn’t be able to install the delay grain and that is the primary thing that holds the case under pressure. Without the delay grain, you’ll have…   Read more»

Oh, by the way, on the original CTI forward closure post. Build the motor including the delay grain, plug the flash hole to the ejection well with grease and install no ejection charge, just stuff the well with dog barf…   Read more»
