<p style="margin:0;padding:0;font-family:arial;font-size:14pt">Initially I was thinking that I wouldn't use 75mm size motors that often back here in Blacksburg, and would just mainly fly on a 54mm adapter. However, at 32lbs it seems that not that much in 54mm will do the job on this bird (5:1 thrust requires an avg of 720N thrust, unless looking at VMax or white thunder).. so it's looking like 75mm is the most useful size motor for this thing.</p>

<div>CTI Hardware for 75mm was built specifically to fly Aero tech reloads. It was developed for the (military/scientific?) community when AT had their production stoppage. There are physical differences - I presume to circumvent patents - which requires an additional o-ring of standard size, avail at Amazon for under $1 each in qty 5. But there is no functional difference.
<div>I decided to skip 54mm HW and just fly big 38s with an adapter. (tho I have CTI HW, so who knows what will come of that) </div>
