I saw these kits ages ago when I was younger, especialy the the one that looked like a gyrocopter and had a tricycle landing gear. Realy wanted one back then, but it was too expensive for me, and helis did not interest me that much anyway.

But MHM in Germany produce them again, and I decided to get it now.....better late than never :-) http://www.mhm-modellbau.de/part-S2884H.php

I love the old helicopters, and think they are cool. I dont fly 3D, and enjoy just flying around in a scale manor.

But this is an oldie, that is brand new..... :-)

Its not packed in a fancy box, but it is very wlll packed with lots of foam to protect the contents.
No instructions included, but they can be downloaded from the homepage: http://www.mhm-modellbau.de/pdf/S2884H.pdf

All the bits look great, and the main bearings are alredy installed in the plastic frames. Canopy is 2 part clear plastic. Fun Tech 570mm composite blades are included. For the price of 200 euro, I think it is great :-)

I am not spending a fortune on this helicopter, so I got the ASP 52H engine for mine. I must say, that the quality of the motor looks great.
I will dis-assemble it and check the internals for quality, and see if it is clean inside, just to be sure. It is very inexpensive, but im sure it will be great just by the looks of it :-)

Here are some pics :-)

Construction started.

This is realy an old school heli.
Very over engineered, and complicated and heavy built. And it requires skill to assemble it properly. You can easily mess up, and assemble stuff incorrectly.
But I like it. :-)
It seems very durable.

I had to sand a few spots on the clutch liner so the clutch bell could rotate smoothe, and not drag.
There are lots of different spacers included for different types of engine included. I have not tightned the clutch assembly yet, as im not 100% sure if I need any of the spacers. will have to assemble a bit more, to see how everything lines up. Engine mount will also be finaly tightned at a later stage to align it properly.....you can move the engine around quite alot, wich is nice when you want to line everything up :-)

Pics so far:

Thanks, you too :-)
The Conquest is an upgraded/later version of my Moskito sport II isn`t it ?

Finaly got a little time to go on with my assembly :-)

Assembled the main shaft and one way mechanism.
It is very mechanical, with springs and pins running in a one way track.....very industrial design :-)

I have been struggling with the clearance between the main gear, and the gearbox/engine assembly.

If assembled exactly as the instructions state, then the main gear mesh to the gearbox is way too tight.

The height of the gearbox can not be changed, as the 4 bolt in the frame do not allow for any adjustment.

The only thing I can adjust is the shaft/main gear height by either adding washers, or removing washers between the main gear, and frame bearing.

The manual shows one washer/shim installed. But with it, the gears are too tight. I have removed this washer, and the gear mesh is much better...still a bit on the tight side.....but I cant realy change this.

The main shaft is symetrical in both ends, so you can not install it the wrong way around. But I have tried to install the main gear on both ends anyway, to see if it made a difference....but same result.

I dont like straying from the manual, but it seems like the best option here.
I have had it taken apart, and checking, and assembling again heaps of times now to see if I had made a mistake somewhere, and I can not see any.

I have been dry fitting a few parts to see how it all fits together....
Next step is the tank assembly.
Seems like the tank is just pushed sideways into the frame, and not atatched in any way......I can imagine it vibrating out by itself.....?

I found my problem.

The bearing block for the tail gear is for some reason too tall.
That results in the tail gear to push too hard on the main gear, and make it all bind up.

Without the tail gear block installed, and all the shims/washers installed as stated in the drawings, then everything runs great.

So I have shaved of a little plastic material from the bottom surface of the tail gear block to lower it a tiny bit, so everything runs smoothe.

Should not be nessecary, but i guess that is what it takes to get a good fit.

More progress.
Im now very satisfied with my gear mesh now...took some time to get right.

Got the tank assembled, and fitted.

The two frames bolted together.
I have not bought the muffler yet, as Im going to order the Robinson R22 canopy from the same store, but it is not in stock at the moment.
Will have to be disassembled again later to install the muffler.

Cooling shroud installed

Mechanical mixer assembled and installed.

Swashplate and pushrods installed.

Next step is assembling the tail rotor shaft. :-)

Heres the R22 fuselage and muffler designed for this kit.

But I cant get the skids, and the tail any more , so I will have to figure something out :-)

Thanks :-)

Yea, using airplane engines with normal sized cooling heads is asking for problems :-)

Some more done today.

Got the tail boom finished.

Assembled the tail rotor gearbox.
It did not go together as the manual shows.
The drawings and measurements do just not make sense to me.
If assembled like the manual says, then the tail shaft will be able to slide sideways inside the housing through the bearings.

Anyway, I used commen sense and assembled it, and it runs great, and the pitch slider is very slop free.

It is a bit fiddly ataching the tail gearbox to the tail boom, and making sure all the flats on the shafts lign up on the varios parts, and they all have locktite, and make 100% sure everything ir right.....otherwise you will be in trouble :-)

Got the skids and tail fins installed.......and no more for today :-)

Rotor head:

There are millions of parts :-)
Assembly was streight forward, and no hickups.
You can tell it is german engineering. Very tight, and no slop, and seems well built....but a bit complicated :-)

This sure isn`t a quick build like a raptor or something more modern.... :-)
But great fun anyway.

Assembly of all the control rods.

The Servos that I have bought, are taller than the "standard" Futaba 3001 servo, so to make them fit I will have to put shims under the servos to raise them a little.....

I might try find some others that will fit.......maybe :-)

Ordered the scale muffler, and Robinson R22 canopy today.

Semi scale Robinson R22 fuselage arrived, also with the zimmerman muffler.

I also began to install the servos :-)

Robbe Mosquito 2
I had three of them flying and a fourth for parts including the tri cycle dude! I used NHP 550 Blades and a OS 50 and it was faster than you can believe. It was called Heavy Brick etc. I also heard they called it The Abomination of helicopters however ! I have the tri cycle and Hughes 300C kit!

What a fantastic project and a great helicopter. From a time when it was all just about the not so simple fun of sport flying. When I bought my first heli I had a choice between the Mosquito Sport or an Ergo 30. I chose the Ergo 30. I have a new build Ergo 30 now and absolutely love it.

https://rc.runryder.com/t793604p1/

I would love to buy a Mosquito Sport at some stage as well. It would be great to see the Futura back in production in the future. I would definitely buy a Futura SE.

Futaba T18SZ, Hirobo fanatic!

Mosquito 2
The next project would be to purchase another helicopter and use T6 aluminum cross gear to the wheels for the tri cycle chopper! Running landings are a blast, the fun factor is great with this helicopter!
