Yes, as with many things “the Devil is in the details”. I think how the buttons are attached is most important. Is it Estes BT80 or LOC thick wall paper? Backed by a nut and washer or just a machine screw and Loctite? Etc,etc,That does not surprise me. Then again, red is not VMAX. It may survive it, but I am not doing it.
That depends on the acceleration as the rocket lifts off. If it’s going somewhere around 40-45 feet per second when it leaves the rail the length is sufficient for that rocket and motor combination.Another question what length do I need to launch lpr on these micro buttons. Was thinking either a 4 or 6 foot length?
+1 to what Steve stated, however with most stock built Estes/Quest/Semroc/etc LPR kits using recommended motors a 3' rod (old school rod) has usually been sufficient (for a very long time), I bought the 5' Micro rail just because I fly some heavy scratch built models and wanted the extra length. The 5' micro rail is stiffer than the 3/16" rods those rockets used to be flown off. This thread reminds me I need to order another 100 sets each of the micro and mini buttons.That depends on the acceleration as the rocket lifts off. If it’s going somewhere around 40-45 feet per second when it leaves the rail the length is sufficient for that rocket and motor combination.
