Has anyone built the Astro-X Wasserfall sold by Hobby Time? If so, any info you have as to quality of components, build, and flight would be appreciated.

##### Keel Loopy
I've never seen it. Got a link you can point me to?

The actual link for the page with the rocket is:

https://www.accountwizard.com/clien...0d90k090ASite1k01d701E&page=item&itemid=11926

It's kind of a strange website (logs you out if you haven't been there in the last 15 minutes) so if that link doesn't work, try the following.

The URL of the store which sells the rocket is:

https://www.accountwizard.com/clients/shop.asp?Web=hobby-time&newsessionid=yes

Click on the "Rocketry" link, then the "Rocket Kits" link, then at the bottom of the page, click on the "Wasserfall" link.

Gus,

Thanks guys.

It does appear this would be cheaper to build with BMS parts. I was just curious because the Wasserfall is apparently the only rocket produced by the Astro-X company, and Hobby Time is the only place that sells the kit (hmmm...).

The only other company producing a Wasserfall kit is Das Model / Physicis of Flight, and the quality of their kits seems to be substandard per other posts on this forum.

I guess scratch-build is the way to go on this one.

Actually hobby time makes 2 kits .the bt60 wasserfall
and the bt80 Black Zombie 1b
they contain estes parts ,precut fins and adequate instructions
heres a review I did on the Black Zombie ,although I didn't build it stock from the package

I also agreee that they are a little pricey

Styme,

I forgot about their other kit (I had already found and read your review, very nice ).

Gus,

A scale Wasserfall would be easy...if ya had the plans!!

I do!

Peter Alway's book "Scale Bash" has a parts list and fin and wing patterns for a BT-50 size, BT-60 size and a BT-80 size model.

The scan is too big to post but email me and I'll send you a copy that way.

Anybody else that wants one can email me to:

Sandman,

Thanks for your incredibly generous offer.

It made me realize what a slacker I've been, so I just ordered my own copy of Peter Alway's book, as well as a few others I've been wanting, from NARTS.

Thanks again,

Gus

Since we're talking about Wasserfall conversions, has anyone got a BT80 Wasserfall Rocksim file? I'm thinking of doing a Silver Comet conversion with a 24mm motor mount but i'm afraid that after I add nose weight, I'll wish I'd done a 29 mm.

Acording to Peter Alway's "Scale Bash" a BT-80 version of the Wasserfall's CG should be 11.5" from the tip of the nose.

Hope that helps.

Thanks, sandman, I've got scalebash too--what a great piece of work!

Reason I wanted a rocksim file was to get a weight estimate on the finished bird. My BT-60 Wasserfall weighed in at over 6 oz. I suppose I could scale that up and guess that the finished BT-80 version would be about 12 then, right? Not bad on a D12 but not overly impressive....

I'll try my hand at a Waserfall rocksim file and post it...

OK,

I decided not to spend the $27.50 on the kit. Instead I spent$94.05 on books to help me save money on the kit.

I remember taking a logic class in college, but I've lost the textbook. Hey, maybe I'll get one of those too! :kill:

Worked this out yesterday. The BT-80 Wasserfall sims to almost 500 ft on a D12-3--not too shabby. And only .85 oz in the nose.

If I get V-2 parts (tail cone and nose) from BMS, will those parts be what I need to get started on a Wasserfall? I think a BT 60 version would be cool.
