R141 NAR S & T New Motor Certification

[BEC]

If John will forgive me for this..... Semroc has just released a kit especially for these 29mm BP Estes Es and Fs: https://www.semroc.com/Store/scripts/RocketKits.asp?SKU=KA-33

I will be bringing one of these to NSL with express purpose of trying out one of these new motors. I'll also have a motor mount for my SLS Aero Dart that will be for the 29mm BP motors (in addition to the one I already have with an Estes 29mm motor retainer in it for composite 29mm motors).

Is there a spec sheet on the F15 yet? Specifically I was wondering about the burn time.

Yes.

Oh thanks shread. I didn't think to look for it in another thread. Is it common practice that billspad makes a thread for each NAR certification number? Or is that the plan going forward? I only see them for R134, R140 and R141.

Yes. Whenever NAR certifies a motor, a public announcement is made. Bill posts on TRF and other sites, however you can find all the information at
https://www.nar.org/SandT/STchrono.html and the thrustcurves at https://www.nar.org/SandT/NARenglist.shtml

Thanks, I've seen those. I was trying to find a system where I would know every time there is a new motor certification in the interest of keeping the Excel sheets up to date.

The last link has not been updated in many, many months and does not contain the PDF data sheet for the E16 or F15 from Estes. Obviously that is critical once they hit the market and people have them to fly, but if folks are planning in advance it would be nice to have that information on the NAR website and not just on TRF.
