Future L3’s

[Ed Dawson]

I to am very interested in the ‘bang for the buck’ that 75mm gives you in terms of altitude. I also love the long burns. I guess what I’m saying is that if CTI had a moon burner, or big dual thrust 75mm, (i.e P75-6GXL) I’d be the first in line to buy one. (assuming I had a job by then)

[Chris LaPanse]

Definitely. A dual thrust Imax similar to the M1300 I flew, but with an extra grain or two would be one heck of an altitude motor. An Imax moonburner could be interesting too…

Great discussion! I say we sort this out a bit east of Gerlach, NV next summer???

Jeroen – any chance there’d be a 9KNS 75mm motor in production by then?

These are in the planning stage right now. We will probably (?) have some slow winter months during which there will be time to develop this. The same casing/motor would be the 9kNs motor that JW is asking about.

It looks like we have our new contest – the USSS – Uber Single Shot Sweepstakes.

Highest altitude, one shot, 6 grain 75mm CTI motor.

$1 to enter and the winner takes the pot. Can be flown anywhere in the US in 2010. Must have photos of the construction / design / flight posted on the net somewhere.

To run a good contest, raise the entry and we’ll probably need some sort of recovery rules and/or time limits from lift off to flight line return. Gee, now I need to build another rocket.

Any chance we can get a higher waiver for MHM ’10? …. say 50k? I’m designing the Mongoose 98 for my L3 but also for the 98 6GXL – and since we had a successful staging on our recent trip to Black Rock we’re hypothesizing a 3 stage Mongoose 98 – 75 – 54 Definitely Black Rock Material. -Sean

Sweet deal! Thanks! I’m starting the design process on my L3 now – its based on a Mongoose 98 minimum diameter and would prefer to fly it on the M3400 over the M2505 if possible… could you send me the thrust curve as well?
I’m also planning on flying it on the P98 6GXL but am not wanting to break the waiver on my cert flight so it’ll likely follow.

Sean, We fired the motors for the M3400 certification this weekend. Everything went quite well. I expect CAR to announce it in a week or two. I don’t have your email address. Chris has the thrust curve, he can email it to you.

We also fired a ‘monster reload’ for the 6GXL succesfully. If CAR signs of on it (don’t see why not), we have a cool N5700 for you.

I think that is a super idea!

Maybe we should have 5 competitions: highest altitude for each available motor size (29/38/54/75/98 ) for the 2010 season on any CTI motor (single stage flight, to keep it simple?).

We could contribute some interesting prices.

NOW we’re talkin’! That’d be a fun contest…
