Default Were to get E9-6 Rocket motors in bulk?

Ill be honest I don't have any rockets, but I just finished a sweet 160in 76 pound C130 that has 6 of these E9-6 Rocket motors in the tail to replicate Jato take off (FATBOY)

These things seem to be crazy $ and considering I will use 6 for each use at once $$$

Where can I buy these in bulk, like 50 or so at one time?

Thanks Mike

The blister packs are part of the shipping certification. To ship them bulk would either be a $$$higher shipping classification, or Estes would have to apply for shipping certification packaged in bulk cases - to sell 50 or 100 motors that ain't gonna happen. IMHO best bet is to get friendly with a distributor and buy a case of retail packs.

You should have thought of that when you were planning on building such a monster. What kind of FAA certification do you have for that thing?

Don't think that is big enough for 6 E motors. A guy used to use a single E-9-6 on a 110" Dromader ag plane that weighed about 45lbs and it was plenty. Might want to consider 6 C motors especially trying to get them to light all at once. Effect is better than turning it into a Boomerang spinning out of control because one side lit fast than the other. I have some practice with this....

D12-7's will give the same duration of effect.. a second less thrust, a second more delay, less money. And C's aren't a bad idea - you can get C6-5's in bulk packs of 24. Just don't forget you need 3 amps per igniter, take care of delivering enough current on demand and they'll go unless the igniter is damaged.

At 2lb average thrust each they aren't exactly JATO bottles, you're not going to pinwheel a 76 pound model with a misfire. I'd be surprised if you could even tell from the effect. The delta V on a 76 pound model for 6 E9's (they test out at about 28Ns total impulse) is around 16 feet per second or 10.9mph. Helps a bit and I bet it looks way cool.

Ok. Maybe your right I should go with the smaller motors. It's already built but maybe I can fill the sleeve that is already there.

So C6-5s is the booster only part number?

LMA-1 is the bracket this plane fits in. 55-77 pounds. It was 82 with the RC tank that drives out but the 77-125 pound class is a pain as you have to get re inspected every year vs 1 time in my class.

A buddy built a device device for me to fire the motors but it's useing a 9v. I guess it will be to small

You have to have $4 million insurance policy and buy a license that costs $20,000.

You can use an adapter to fit the C motors (18mm, Estes BT-20) in the D mount (24mm, Estes BT-50).

The booster only motors have a designation -0, such as C6-0, D12-0. Motors with a -7 or -5 etc, that number is delay time in seconds before the ejection charge blows forward.

PM me.. we'll talk offline, I'll show you how to use the regular motors safely for this - you can then use the bulk pack motors and enjoy the extra few seconds of smoke trail from the delay.

Looks like you can buy the C6 motors in bulk for about .50 each. http://bellevillehobby.com/educator-...k-pack-engines

High power rocketry has 2 national sanctioning bodies, NAR and Tripoli Rocketry. Check them out there
may be a club close to you, they usually have a vendor on site you could go buy from directly.

Yeah but you won't do great on the price. The bulk pack C6-5's are probably the best compromise for cost and special effects. 7 seconds of fire and smoke.

So do these have the forward discharge to push out the shoot? I was told I could epoxy the front to prevent this from happing?
