Are you looking for class 1 (one) motors or "I" class motors?-makes a difference. Single use or reloads? Cesaroni or Aerotech? If you are in San Diego, we order from Wildman West for CTI and get them delivered at Holtville (our launch site). All CTI have a HazMat fee. For Aerotech, mostly we'll order from Balsa Machining Supply (BMS) as a lead time item and save a bunch doing that-we can get orders divided amongst ourselves, so the HazMat effectively disappears. If you fly at the lower end, look into the Hobbyline (40-120) list of reloads OR you could get your rocket launchin' butt to Lucern (google 'Rocketry of California') for a larger launch, say, ROCtober or ROCstock and visit the vendors there. There are a few "E" and "F" motors at Hobby Lobby-google the one closest to you. know of only one hobby shop in San Diego that sells G-80's but stocking is 'variable'. Reloads really do give you more flexibility and bang for your buck if you fly enough to amortise the cases. Straight smoke and good chutes, brother!
