"Great reload for the buck"
SteveAwesome (Highlands Ranch, Colorado)
Great reload - I needed the shorter delay for my 4 rocket - these reloads do not disappoint - great power and a great price. Hobbylinc cannot be beat

"Good bang for the buck"
Great way to learn how motors work! Make sure that when you build one of these you close the forward and rear closures well, or else you'll find out the hard way what happens. Aerotech is pretty good about getting you a new casing if their product malfunctions, however they'll take their sweet time doing it. I've never had any problems with the G76 reloads. They're loud and powerful, great bang for the buck. Although assembling it is fun and all, if you have a bunch of mid power kits you want to launch on the field and only one or two casings, you'll spend half your day on the field building the motor instead of launching.

"Great impulse and flame color for the money!"
Great reload for the Mega der Red Max by Estes! With light winds the 4 second delay results in a perfect deployment at apogee. It's fast; so watch closely or video the launch, to appreciate the bright green flame. Good impulse for the buck, with an impressive altitude. I just bought more reloads to enjoy the magestic flights with the der Red Max. The 7 or 10 second delays are great for the Estes Partizon and this reload sends it way up there!


Use only AeroTech/RCS RMS Reload Kits and motor parts to refurbis your RMS Motor.
