Ok, at last it has been released, and I think I am one of, if not the first, to receive this kit.

First impression is that the kit is very nice and I am not disappointed. It is well thought out and the manufacutring is clean. On german overpriced toy standards, it is a good value for the price. I don't mind paying more for a really good product and this meets that expectation.

The body itself is clear lexan. The lexan is very clean, tough, and is perfectly straight with no thin spots. All sections fit together very nicely. All window edges are molded into the surface as are all drill points.

Framing comes on one sheet of laser cut plywood, perfectly flat and all cuts are clean through and precise.

There is significant interior framing, which sits the mechanics about an inch and a half above the bottom of the fuse. Landing gear are formed brass tubes, that connect to typical eolo skids. Fins are held in place with wooden dowels that I will upgrade to carbon tube. On mine, I ordered carbon landing gear (similar to those on my millie in my gallery) and will be modifying them to get the right geometry which will require shortening the skid heights (different for front and rear) and they will have to be split and narrowed. I will also be narrowing their profile, and shortening the skid tubes. I think this will add a lot of strength to the landing gear and will look really nice too.

The body is divided into three parts, nose section which ends behind the windows, mid section that holds the mechanics, and boom.

In addition to the mechanics' support framing, there are formers that go on the inside of the fuse to keep it rigid at the nose to mid section interface. There is a former for both, and to release the nose, typical white 4mm plastic thumbscrews are provided for you to reach through the rear windows to access, in order to release the front end.

The mechanics support structure is designed to hold the battery underneath and the battery has room fore and aft to be moved for cg.

If you wanted to use the 3S2P brick battery mounted on the front (as is shown on the eolos in my gallery) there is plenty of room, but I am not sure how that will work out with CG.

There is a lot of interior room in the fuse. The expect a big hole to be cut in the bottom, I expect for cooling. I may opt for a smaller hole and install a fan to draw air out of the bottom.

Looks like it will go together very easily and quickly, but I will be doing an extra nice job and will probably west-system coat the internal framing before installation.

The clear lexan will have to be painted from the outside since the formers and frame are glued to the inside surfaces.

Two metal (aluminium) scale exhaust nozzles are provided, but I think I will replace those with something lighter which will be easier to glue to the outside of the lexan. Doesn't seem like they would stay attached very well.

I would recommend the SE torque tube drive so that you do not have to fiddle with attaching the wire drive couplers to the wire. I am guessing that you cannot use the belt drive because the belt drive setup is shorter than the torque tube and wire drive setups, though I have not verified this. At a minimum the mechanics location would have to be changed and it would be a trick to install the belt, though I suppose it possible.

I will be spending time on http://www.helispot.com researching cool paint jobs, maybe the Hawaii tour scheme with the palm trees on the sides, or perhaps something more flashy and visible in flight.

I will set up a new section in my gallery to show all the parts prior to assembly and as the project comes together.

I would definately recommend this kit to anyone interested. Thanks to Alex for getting me one of the first that became available.

This one is going to take a few months before it is all done.

Today I will coat all the formers with West System

Stet,
I'm not familiar with "west system" ... what is it ?

Also, do you have any idea how much weight the whole thing will add to the Eolo ?

Thanks,
Demos

Hi Stet,
A question :
When it is all done, will the chassis be at an angle with respect to the ground (like the pod and boom kit) or not ?
I've noticed that the front landing gear is shorter than the rear.
Does the lower frame account for that ? or is the whole thing
supposed to sit at a slight angle to clear the tail fins ?

Thanks,
Demos

West system is a 5:1 epoxy resin used in yacht construction. good for carbon and FRP

When you consider that the alternatives are limited to the simple lexan bodies that are really flimsy, and come with no hardware or framing, I think the kit price is not too far out. For what you receive it seems skimpy but there is a lot of tooling and development to be paid for. If done right it will make a really first class finished job.

The lexan is really nice, evenly molded and just the right toughness/thickness.

Weight addition, not too much, I'll have to weigh it. It will add weight, but for scale flying I think it will be fine. I use 3S2p, but my buddy uses 3S4P on his eolo and it flies great. I imagine that the added weight is about the same as a 3S2P battery or less. The boom without fins or hardware weighs 28 grams

As far as the skid heights, they are different to acommodate the shape of the fuse which has higher clearance at the rear skid, a scale feature. As far as tilting when done, I will take some pics once I have the boom attached and the skids installed. I am building carbon skids for more durability in hard landings.

I believe the internal framing is to locate the rotor disk at a semi-scale location as there is a lot of height of the fuse to be accounted for.

West system is an excellent epoxy resin that you buy at boating stores. It is a whole family of products. Various resins, different speed catalysts, polyester filler (can make it very light and not sag), colorants etc. As far as scale projects, I have found it to be the best thing going. It is absolutely fuel proof. The compound will stick to fiberglass resin, but fiberglass resin will not stick to it.

The West System stuff comes in cans and you can use pump caps to meter out the right amount, but my pumps are old and get bubbles so I measure volumes. 5 parts resin to one part catalyst.

Thanks for the replies guys.
So do you spray west system on the wood parts ?
Or apply it with a brush ? Or ... ???

More questions (I hope I'm not driving you nuts ...) ...

How wide is the opening for the battery in the lower frame ?
What is involved in the modification of the rotor head ?
(I can't tell from the picture you posted...)

Thanks again,
Demos

Battery tray width is 5cm as measured on the insides.

It is a tight fit with a TP 3S3P pack. The 3S2P brick fits just fine and I am considering using two in parallel, maybe just one.

Anyone who thinks the kit is expensive, just consider that to build up a nice eolo with good digitals, gyro, controller, motor and upgrades, the base helicopter ends up being at least $1500. Another $175 to make it into a really nice scale job is really not that much.

I agree Stet, This does look like a first class kit! The price isn't bad but it is more than I was expecting for a lexan fuse kit. Just a bit of the old sticker shock

after my experiences with the lexan canopies, I think it is the preferred material over fiberglass. Easy to finish, and in this case light. Plus all you need to do with the windows is mask them off, no gluing in separate windows, a major chore.

I pressed Alex to do a good job packing, which he did. Built a close fitting box around the kit box, which arrived in perfect shape. Shipping that big box cost plenty too (mostly empty air). If it were me, I would build a minimum size heavy duty box to ship it, but the effort to do that (time is money) would eat the margin, or cost savings in shipping fee.

When I have had damages in the past, it has been addressed and taken care of without question.

Got mine today. Alex at RCMarket did a great job having the fuselage kit packed properly. Not a scratch anywhere and it is a beautiful kit as you would expect from Robbe. My Spirit Li has a new mission now.

I am adding pics to my gallery occasionally, so check there.

I tried fitting the belt drive setup to the fuse, and it didn't work too good because it was too far forward (shorter boom). So if you want to use the belt drive, be prepared to move the mechanics and mount rearward by a certain value. I will do a comparison later and tell you how far to make the change. Myself, I have decided to use the SE torque tube setup which has the couplers in the ends so the tailbox simply slides on.
