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»

what’s trf?

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

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»

Actually, the one you video’d for me was the Cessaroni I212 SS for my cert flight. I flew the I285 Redline later that day.Thanks again!-Ken

I guess it all comes down to:What do you want to capture from the flight?andHow much are you willing to spend/risk?For pure dual deploy reliability and peak altitude, I’d say RRC2 or 2x.For reliability and basic altitude logging, MAWD.Beyond those,…   Read more»

I flew my MAWD for the first time last weekend, although just in the record mode, no deploy. I captured and downloaded my L1 and two subsequent flights with no issues. I only wish it had an accelerometer to get…   Read more»

Ed,I plan to get my L1 out of the way in the morning. After that, I can put in some pad support duty (or other L0/L1 suitable job). I don’t have any kids with me this time, so I’m freed…   Read more»

I know there’s at least a 4 footer. I’ve used it a few times with the Suppository.-Ken

Batman, hook up with Lawndartman. He got me set up with 3x F39 Blue Thunder reloads and loaned me 3 cases to boot. Those Fuddrucker igniters worked like a charm.Hopefully, I’ll be up for the April launch with the Suppository….   Read more»

Take mental note… must use more wadding next time.

Adrian,The specs on the M-Tek ematches that Tim carries are at:http://www.electricmatch.com/product.htmlI bought a handful to do ground testing. I also ordered some filament canisters from Pratt Hobbies (similar to Quickburst’s Hot Coils, but tested with “normal” altimeters).Ken

Well, I’m certainly not going to win any awards for a quick build. Only 2 weeks left until Mayhem. At this rate, I’ll be lucky if she flies naked. Updated pictures at http://www.putfile.com/kfranzel/images/77902.Still need to fillet the fins, put together…   Read more»

I’m keeping the L1 flight conservative as well. The same rocket, but no electronics and only one motor. Tim’s L1 deal with Cessaroni is too good to pass up. Haven’t decided between the H153 or H143SS. Both work in the…   Read more»

JK Tim on those motors! I know it’d take 6 small miracles to get such a beast lit.On the other hand, I would like to do it with either BP D12’s or E9’s, then maybe some Blue Thunder 24’s… F39’s…   Read more»

8) Nice, but what are all those holes and tubee looking things for? Anyone got any old F101’s or long burn 24mm Ellis G’s…? Maybe 6? -KenThen again, the question comes up on getting them all lit in the…   Read more»

I’ve got a tiny Perfectflite 15k just for logging purposes. I believe the data is in at least a similar format. I’ve pulled it into Excel, but the baro data is really noisy for pulling derivatives for velocity and accel.Anyone…   Read more»

Might be time for another order from BMS. I’ve got enough 24mm tubing for 6 medium length motor mounts ( 1x 34in tube). Should just order some of their foil-lined stuff so it holds up a little longer.Ken

I’m going to get some small fiberglass tubing at the local kite store. Can someone who’s done airstarts let me know what size (ID) I need to fit a pair of ematch wire pairs through (4 conductors per conduit)? I’m…   Read more»

My original plan was to put the timer (PET2 or Perfectflite Minitimer3) in a small bay above the outboards, but below the fwd centering ring. I’ve got a space between the 38mm motor tube and 4″ airframe about 7″ long….   Read more»
