Even though I was told that it won't fit without butchering the body, I decided to squeeze my trusty old Raptor 30 into an Augusta fuselage. A Long Ranger would have much easier but I really like the looks of the Augusta and I have not seen anyone else do it. For anyone interested, here is how I made it fit:

The only real problem is the slope of the fuse directly in front of the swashplate. The pitch arm needed to be trimmed as much as possible to get a decent pitch range. I wanted to have enough pitch range for good autorotation performance so I needed to get at least +11 to -3 degrees. I ended up getting +11 to -5!

My Hatori muffler stuck out too far from the mechanics to fit into the fuse so I had to choose between a Century scale box muffler or a tuned pipe. The scale muffler is too loud for me and it makes throttle linkage set-up very cramped so I bought a Millenium tuned pipe set designed for the Raptor 30.

2 brackets were made from brass strip to secure the top of the top of the fuse to the mechanics.

1/8" thick plywood was glued and fiberglassed into the fuse for mounting the mechanics. A bulkhead was intalled to strengthen the forward side of the mount.

Blind nuts were installed where the stock Raptor vertical fin would normally be attached.

Foam rubber was stuffed between the tail gear box the the fuse to secure the tail.

Here's a pic of the mechanics installed.

The finished project.

That worked out very nicely........and a good sourcing of items you needed to make it happen.

Agrav8,

Except for deciding on how much to trim from the pitch arm, this liitle project went together very quickly. It only took about 30 hours including paint. If I did it again, I could probably get it done in half that time.

I hovered the Augusta in my front yard and it was very smooth - no vibrations. It needed only about 6 degrees of pitch and a very low headspeed to lift into hover. The tuned pipe had a very pleasing and mellow sound.

The the total weight with the heavy 3000 nimh battery pack came out to only 7lb 2oz. That's what my Venture 30 weighed as a pod and boom! Performance should be very good when I fly it tomorrow. Loops and rolls are not exactly scale manuevers for this helicopter, but they will be in the flight plan if all goes well.

It would be great if more builders out there decide to share what it took to get their scalers together.

I agree

it can be a daunting project,especially when you don't know what to do as a work around.....alot more folks would try their hand in it with a guide like yours coaches them along.

Thanks, Roy.......for sharing and motivating someone else.

Emile,

I recently saw you tearing it up with your Airwolf in the IRCHA video. Hard to believe a 30 could make it move so fast!

I probably should have put a scale paint job on the Augusta, but I really just wanted a sport heli to practice hovering and scale manuevers with. If the weather cooperates tomorrow, I will have some in-flights pics.

lookin' good!

looks pretty cool in flight. yes sir, it is easier to start simple and progress as you go. get the hang of flying scale without the worry of time and work in a machine. after that, your flying will be natural and the building part of it will make it all rewarding. my airwolf flies great and i love seeing the look on faces when they not only find out it is a 30, but it is a nexus. it is all in the setup. too bad the nexus has been discontinued, but the hawk sport is a great replacement. it flies awsome, its cheap and for most fuses, it is quite friendly. it will be used in many future projects.
