Gents,

Does anyone know if Hirobo Freya mechanics will fit into this?

Only $222.40!!

Cheers

I'm sure with a little work it would fit just fine. I don't think that you would want to use that fuse for FAI type flying though.

Nice looking fuselage. Reminds me of the Kalt Omega Jet Stream body.

I dunno. I can't see why it wouldn't be fine for FAI with the windows all in place and maybe something done about the air hole on top for those with models other than Graupner's.

Hi arrio

Yes I remember the Kalt Omega Jet Stream very well....If only you could still get the fuselage!!

OzModeller,

Regards to the fuselage. It should be fine for F3C.

As for fitting the Freya there are a few things to consider:

1) The fuselage is only 153mm wide. It is designed for Heim mechanics where you use a rear exhaust engine. Therefore you will need to cut the side of the body shell to let the exhaust sit out.

2) The Heim also has it's tail boom take off very low. Therefore the exit point of the tail is much lower than normal.

Now.. I've just ordered one from the UK importer to try fitting to my F3C Aurora and it'll be here on Monday.

He said that he had a customer who fitted an Xcell Pro to the body and it worked well.. but the body did have to be cut for the exhaust.

If you want I can post some pictures when I receive it on Monday and start fitting..

Cheers

Mark

you have to excuse my shock, but why exactly would you want such a fuse for F3C? That's a scale fuse isn't it? Maybe we could start having competitors entering Air Wolfs into competition as well? Not that I'd mind, just think it would be odd.

Synodontis,

It's not scale. It just shares a passing resemblence to the Bell Jet Ranger.

In the same manner that the JR Super Gracy is a light interpretation of the Hughes 500. And that is a popular F3C body despite its resemblence to the Hughes.

The Graupner Megastar looks very similar to the Hirobo Jess, TSK Jazzranger and Kalt Jetstream.. all very popular F3C bodies in the early 90's which have passing resemblences to the Bell Jet Ranger.

To be honest I think the Bell Jet Ranger is one of the best looking helicoptes ever designed.. and i'd rather have an F3C body based on one of those for asthetics than the tubby Hughes.

Hi RotorSoft

Thankyou for your input, I would love to see pictures of it and also the name of the shop where you ordered it from as I seem to be running into difficulty getting hold of one as v-eastonline are telling me they no longer stock that fuselage.

As for the exhaust could you not run a zimmerman style pipe?? maybe worth a shot.

Cheers

OzModeller,

I got mine from Motors and Rotors here in the UK. He is the Graupner Heim importer and had them (well atleast 1!) in stock. Website address is http://www.motorsandrotors.com

He doesn't do online ordering yet on his website so you'll have to drop him an email (he also doesn't list the body on his site!).

You could probably do something with a pipe but I don't like running tuned pipes so am happy to go for asthetic compromise. He did say the guy who installed an Xcell Pro into one cut the fuselage and it looked alright even though he thought it might ruin the looks.. The muffler sticks half out and half in the body. I suppose you could if you really wanted to make some exhaust cheeks quite easily to hide the muffler.. shouldn't be hard.

Cheers

Mark

Mark,

The Super Gracy is my favourite fuse shapewise, I think the front section of it looks superb. My favourite scheme is Hashimoto's on his Black Shark T type, the paint scheme suits the Black Shark perfectly. I just never liked the Staysee (although a previous poster by the name of Captain Dan had a paint scheme on his that could sway me), or any of the others for that matter.

So you're going to compete in that fuse?

Synodontis,

For me the best looking fuselage has always been the Blackshark. However I've always had a soft spot for the Hirobo Jess which the Megastar is a very close copy of.

I'm not sure whether I'm going to compete with it or not. It all depends on how it flies. If it flies well then yes I will run it. If it doesn't fly well then no I won't!

Cheers

Mark

Ok.. well I got my fuselage delivered from Motors and Rotors here in the UK and installed my Aurora into it fairly easily. The only real issue is as I mentioned early about the width of the body. This means the side has to be slotted to allow the exhaust to partially stick out. Either way I'm quite happy with the end result. Just need the weather to pick up before I can fly it!

Step 1:
Strip the model down to the bare mechanics.

Step 2:
Trim the body shell for fitting.

(Note the cooling duct needs a lot of material removing!)

Step 3:
Trial fit

Step 4:
Finished! (Note SAB horizontal fins.. stock items are balsa!)

Cheers!

Damm That looks great!! Good job on trimming for the exhaust. Looks like it was meant to be that way. thumbs-up!

Hi RotarSoft

That looks amazing! I will be ordering mine today! I can't believe it went together so easily. I think I will just cut out the side of the body for the exhaust as you did.

Cheers

You know, it really does look nice. Having spent some time around a few guys who fly fuses, exhaust heat in the shell is no small issue. This presentation should deal well with that problem. I'll bet the SOB will be fast as hell, too.

Mark,

What was the MAXIMUM width of your mechanics? How about the footprint width? This speaks to the original query about Hirobo mechanics fitting.

Hi Ben,

The width of the mechanics isn't really an issue because the widest point is always going to be the exhaust point and the main gear point.. both of which stick out beyond the mechanics.

My Aurora has the Avant EFX undercarriage brackets on it which are the exact dimensions of the Freya undercarriage points.

Finally I know an XCell Pro has also been squeezed in.. so putting this all together I would have thought the Freya mechanics would go in no problem.

I'm just waiting for the weather to pick up so I can go and try it!

Cheers

Mark
