Do NOT base your calculations on average thrust of the motor, but use its initial thrust; look at the thrust curve for the motor. Some motors have relatively low initial thrust, but due to a highly...

It might work, but depends on final weight of the rocket. Under 22lbs (including motor, casing and recovery) and with little wind you should be fine (I stress SHOULD). I'd be more skeptical on a...

The liftoff thrust is only about 400 N =~ 90 lbs. That's the figure I would use to determine your max liftoff weight. Given that, I would limit your rocket weight to about 17lbs (including the...

Thanks. Painted with catalyzed automotive paints. I like my selections far more. Takes some work and decent equipment, but it's worth it.


I thought it was rather heavy until seeing others...

Awesome rocket, although I've only flown mine twice. On a Gorilla K555GT, I got 3700 ft. Mine comes in at 13lbs sans motor. I use a 60" Skyangle main with a 24" Skyangle Cert-3 drogue for recovery....

I use one in my Thumper Jr where the electronics are mounted between the fins; it's the only rocket I have built with a hatch as all my other rockets have the electronics in a coupler.

You got that right. I found out the hard way. Totally trashed a beautiful rocket!

IMO, those rotary "spring loaded" 110/220 switches are pure crap! I purchased several of them that went into...

True...they all have the durability (if built properly) to serve you well for an L3 project and many have done L3's on a 4" rocket; that's not the issue. The issue is to be leery of your club's...

I grease the O-rings with Superlube.
I use spray Superlube for the liner. No freezing, no mess, and the liner slides out really easy. Case clean-up with soapy water is all that is needed.

That's a mighty creative 9 yr old!

I just received the Aerospace 1 as a gift. Really cool looking kit. Great graphics! Can't wait to get started building it. I'll be getting the Stilleto soon. It was on my list, but I got other...

Delays are measured from burnout. The delay starts burning at motor ignition, and the physical length of the delay element is determined by the rate the delay burns during motor operation and the...

I apply Future to my LPR rockets after the decals have set. I use cotton T-shirt 'rag' to apply it. Dip the T-shirt in Future (just barely wet it) and carefully apply a light coat of the future...

I'm pretty certain the original 3" Wildman was Hawk Mountain tubing (at least a few years it was, not so sure today.) I think the 4" and 6" versions are Performance Rocketry.

As a flier at NEFAR (though haven't been in about a year), I, too, am curious as to why you cannot fly with them. They are a great group and have a relaxed flying "protocol". Unless you really T'ed...

I had one of those as a kid. IIRC, I had many successful 2-stage flights with it.

Did you remove the previous CTI file from the loaded engines in Rocksim? You need to do that or there might be a conflict between the two files.

Add: I just updated my Rocksim 8 with this file...

I use PPG's Shopline stuff. About $18-$22 a pint (what the local shop carries) for the custom colors I typically like. They can custom make the same colors in their higher line stuff (they have a...

I couldn't agree more with the quality of the Finex guns. I use the Finnex 1000 - plenty of gun for most rockets. I love mine, although I don't have any experience with high-end guns so don't have...

I've used the E20-4W with nice results.

No doubt. Love the filling capability and how beautifully it sands.



You bet. I tend to have a "heavy hand" when it comes to painting. Unless you over-reduce the paint, it's almost difficult...

I like the finish of a spray gun better than canned paint and the color selection. I don't use it on small LPR projects, but have on used it on rockets as small as 2.6" dia.



No doubt. That...

Personally, I'd stay away from the HF stuff. OK, for primer if you want a primer-only gun. Before purchasing my guns, I spoke with a friend who had a few of their guns to ask his opinion. He thought...

I use a HVLP gun to paint my ~ 3" and larger rocket projects.

Dan G posted some great information, but I believe you can use a less expensive system for rockets than he does; I do. I've sprayed a...

11,560 ....

Yup. Version 8 works the same way. You must first remove the updated engine file using the "Reload Engines..." in the File menu. Then, add it back. Exit Rocksim. And Restart it. You should now be...

Great rocket, but hope you have a high altitude waver. A 4" rocket on an M is going to sail to 12,000-15,000 ft.

Personally, I think it's a poor decision to try to build an L2/L3 capable rocket. ...

I use high build automotive primer (usually 2-3 coats, sanding only after the last coat). It fills all but the deepest spirals.

Donald,

Mine is at the same stage. Should be ready for next month's launch as I'm out of town under Thursday so it won't be done by Saturday (if we launch).

Nice to have this rocket in my...

A typical "rule of thumb" is around 50-60 ft/sec decent rate under drogue.
