Yep I’ve never seen any break, except when my rocket came in and core sampled.

Okay, guys, I guess I have over-analyzed this… let’s just light the candle… 🙂

Only ever seen one break from flight but it was undersized. I have seen them destroyed during a Cato (in fact just this last weekend0 But they are VERY hard to kill. Bruce if you aren’t comfortable with the size…   Read more»

I have some good ones from GLR (I think they’re 5/16″) that I use in my deuce and a couple other big rockets – never seen or had one break.

Give me a couple days and I’ll get a page up with the rail dimensions and some other related technical details.Warren

I have a drawing of all the rails that NCR uses and the dimentions of each. I do not know how to post drawings to the wepbage so send me your e-mail and I will send anyone that wants a…   Read more»

I agree with Chris here and they are what I used for my L3 flight last October. The bigger ones also use 1/4 20 screws and are even interchangeable with the even larger yet uni-strut buttons (also available to be…   Read more»

We have rails for both standard and extreme size (1010 and 1515). I use (and love) the large rail buttons from railbuttons.com for my deuce – they work just fine on NCR’s large rails.

Technically, as long as they are within the designated impulse range and NAR certified, they’re good to go.

Or by going to http://www.nar.org/ and scrolling down to motors.

This is the only list I’ve ever known about. NOW I know what you’re saying. They just haven’t been put on the list yet. Of course, they’re legal.

Bruce,The list can be found here: http://www.nar.org/SandT/pdf/CombinedList.pdfOr by going to http://www.nar.org/ and scrolling down to motors.You will see that the list has not yet been updated and the motors I mentioned are designated as in process. I emailed John Lyngdal…   Read more»

The latter is a more difficult standard, and so forever we have had great looking safety certified motors that could not be used in NAR sanctioned competition events.Well, finally a question I can’t answer. I always assumed ANY motor certified…   Read more»

Bruce,For sure, but for those in the NCR membership unaccustomed to competition flying, there are two classes of nar motor certification, safety, and competition. The latter is a more difficult standard, and so forever we have had great looking safety…   Read more»

As long as they are within the impulse range and are NAR certified, they’re good to go!

John,In addition to a potentially spectacular failure/success N class two stage rocket that is being detuned to meet waiver, I hope to fly a full L WR sunday. I’ll be very interested in the M superonski as I want to…   Read more»

My good brotha Bix…Good to see ya in the mix. I started a thread on this in the Research section may be of some help. Havent seen to many folks yet post what they were bringing. I am pretty sure…   Read more»

RD & DD,Don’t worry. We’re going to confiscate your transmitters… kidding. It IS important that anyone with R/C to indicate their frequencies before flight, and it will be up to the RSO as to which flyer flies first, second, etc….   Read more»

Ron,If we have more than three entrants doing R/C I’ll be amazed, I’m flying my primary bird on channel 30, my backup is a 27Mhz unit. But sure we should be careful as i’m with you, I need no assistance…   Read more»

Still fun little motors – amazingly loud for hybrids 🙂

Hmmm I think I know what Edward had planned.. But I wont say.
