Ken,There is a discusiion on info central I remember reading when I had the same thoughts, and the perfect flight manuals, eg the MAWD, have a brief tutorial that can be downloaded from the site. Generally, I don’t think it…   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»

Since you’re dealing with a 38 main and 29 outboards, do you really need to do DD? if not we built the timer (PET of course) into the coupler area of the VV2 (civil air patrol project) which ran a…   Read more»

There’s a couple ways: one i have done 2/2 tmes, the other I have heard mentioned.First the way I know it will work:Use copper foil–can be adhesively backed or not. Locally i have seen it at McGuckens, but McMaster-Carr stocks…   Read more»

If the timer is in the front ebay, how do you get the connection between the main airframe (with wire conduits) and the bay?-Ken

Ken,Since you are still doing construction, I recommend running small tubes from the forward compartment to the aft of the motors. There are several different ways to airstart motors but if you have a tube to pass ignitors through, it…   Read more»

chris,yea the k250 (old version–reputed to be a 2 percent L–think you told me that). The problem with the L is the dearth of long burners–the L330 being the exception and only a modest L at that. The low hanging…   Read more»

Agreed, and now that you mention it, I think you’re right – it’s an 80something percent K now. Because of that, I seriously doubt the current K record will fall anytime soon…Still a cool motor though There were a ton…   Read more»

Definitely – the Loki K350 is a wonderful choice for a moonburner K now, and a lot easier on the wallet than the Aerotech offering.Anytime you get away from the single use, it sure helps the wallet… but it does…   Read more»

ignore this

which makes the Loki K350 priced at around 100 dollars on discount at 2374N-s (85percent K)–a real bargain in my view.JS

I believe I may have flown the last full K250 in captivity last fall.

JW, I remember seeing that flight, and it was very impressive. 🙂

The K250 is now something like an 82% K. It used to be a very full K, but when it was recertified, they went to the lower impulse.I believe I may have flown the last full K250 in captivity last…   Read more»

I know you can get K250’s now, but they’re about the priciest K motors around ($200-$250). Wonderful though, as a 10 second full K.

I wasn’t sure if AT still made them. If you can get one or two I’d love to fly them. If not, I guess I’ll have to settle on a K185 :(See you at the annual meeting.

One problem with drag racing 2 or 3 K660s is making sure everyone uses different tracking. We should put our heads together at the meeting to see who is wanting to do what.We also need to have ideal conditions from…   Read more»

Tim,I’d love to try the J125. I have an I65 I plan to fly at MHM as well. Been hanging onto that for a while….Now I have the perfect rocket for it.JS
