Hawk mountain raptor

Postby hotspot » Wed Aug 13, 2008 3:26 pm

Got the Raptor ready to go about a day to build one of the things I did to the kit was reduce the length of the avionics bay to eccept the perfect flight altimeter. Think it looks a little long for its diameter anyway first flight will be on the G64 and then the I268.

Nice 8) If a G64 puts it to 3000ft, an "I" motor would push it past mach 1 and to ???? ft... should be a cool flight :lol:

I think that would be a H 268

A G64W goes to around 2,500ft @ 0.53, the H268R gets around 4,500ft @ 1.07, and the I200W puts it to just on 5,000ft @ 1.03.

The Raptor is just short of optimal mass to be a real altitude killer or a super speed demon.

Many people think it is all about lightness and wonder why they fell short of their predicted altitude or speed......

You can always throw that golf ball further than the ping pong ball with the same amount of effort :wink:

Thats correct it was one of the reasons for getting the kit thinking of only making it single deployment and having it deploy close to 5000 ft is perfect for me. Gets a little silly having a single deployment rocket deploy at say 8000. I have the Firestorm now flying dual deployment able to get to those higher altitudes.

always wanted to get one of those rockets! how was the build? and how much was shipping and what not? im thinking of making it electronics deployment and flying it with a hybrid, nice and long burn time
Will fly beer for rockets

When I got mine I think the OZ $ was around 0.78c and the cost of the Raptor including extra payload bay and Slimline retainer was around $105 USD. The shipping worked out to abou $40AU.

It would be one of the easiest builds I can think of.

Glue the retainer onto the MMT (It's not a "TRUE" minimum diameter rocket)
Glue the Kevlar ribbon to the MMT
Glue the MMT into the Airframe
Glue the fins onto the pre-slotted airframe
Assemble the piston
Glue the bulkheads into the NC and payload bay
Attach the eyebolts
Connect the quicklinks
Pack the chute

Just fly the damn thing!

As Scoop said very easy to build people have added extra strength to the area that the fins attach too maybe a fin can would be better as used by GLR. Think it would be interesting as dual deployment as it would be very fiddly but not impossible.

I wasn't necessarily interested in making mine DD, but really folks you wanna prove if this sucker goes supersonic, by having some form of logging device.

I set mine up to take a G-Wiz MC2 because it has all the kewl accelerometer stuff, and because it can log a few interesting variables.

Lets face it, unless you are doing some form of testing, it really is just letting fast crackers off!............ Not that I have a problem with letting crackers off

Using my rrc2 from missile works gives FPS data very good.

Raptor flew well first on a G64 then a H128 still looking.

Bummer...did it go over the horizon or have the crops claimed it? If I recall correctly you have a pretty good record of recovering wayward rockets, hope your luck hangs in there for this one!
Those H268's are pretty mean motors, even the Matrix took off fast on those and its probly twice as heavy!

bugger, :? but it's all FG so hopefully will turn up in good shape as long as something doesn't step on it.... alot of $ there with motor hardware and altimeter....
