Oh, Yeh !

No, it's a side by side boxwing design, but not a Ligeti Stratus.

Bevel gears in a counter rotating gearbox makes it too complicated and heavy; it can be done with spur gears only and will run smoother an quieter. 

Just go up 4 posts; the 3 view drawing is there; it's fully enclosed so you can't see the internal tube frame but basically the same setup as the HM-1000

But not a flying flea design; it's a boxwing.

There isnt a lot of wriggle room if you dream includes a couple of 100-150mm dia high speed bearings and a bevel gear system with torsional vibration dampening - I dont want to appear to be a troll or naysayer, I know how difficult it is to design and build an aircraft within the RAA regs.

I don't know where you got 100-150mm high speed bearings and especially a bevel gear system.

If you look closely at the HM1000 photo you will see the tube that has the prop hub is about 44mm so the solid bearing shaft would be 38mm, so the bearings would be 38mm ID x 63mm OD x 4 off (2 at the front of the hub and 2 at the hub. This is a proven system and has been operating for nearly 20 years.

Being a belt drive it gives you the required reduction and would be turning the prop at about 2700rpm max. and using belts, torsional vibrations are almost nil.

The top support for the rear fuselage is that thin solid round bar (about 20mm OD) that connects to the 38mm solid bar at the front of the prop.

Haven't got a clue where your bevel gear system would go.

This is another brilliant mid tailboom propeller aircraft; the HB-204 Tornado tandem seat trainer.

This is my concept mid boom propeller aircraft; a bit heavier the yours at 600kg MTOW and the boom has more support from below.

It should have very good handling characteristics and light on fuel. 

Unfortunately no folding wings.

The HM-1000 (which is a Flying Flea design) in the above photos has a Rotax 582 engine.

Now watch the video and see how well it performs.

REALLY ?

Hi Deskpilot,

Been following your design from the start, where are you up to with it.

I've had a passion for the tailboom propeller aircraft because of the protection given to the prop and the better efficiency. 

Counter rotating props could be done without being complicated.

I've been tinkering with a boom prop design myself.

Hi Ian,

Are you still sending out the "Last week's most popular topics" each weekend ??

I haven't been receiving anything since August last year.

Cheers,

Graeme

I've listed this engine in the classifieds for anyone that may be interested

Well, the latest news for the Aquila Airpark in Maryborough is :  DEAD

There has been no interest shown since the FCRC Approval and the owner/developer has called it quits; he's not prepared to spend $5M on the off chance some aviators may become interested.

He has the property up for sale on  https://www.realestate.com.au/property-house-qld-yengarie-130542762

Development Approval has lapsed and is not included, but could be resubmitted by new owners. 

Did you get my emails of 9.12.18 and 18.12.18 

Hi Ian,

Have you fixed that link  "Please see here for details of being registered as a Supplier"

I am waiting to register for the products that I sent you in emails which haven't been acknowledged as yet.

I would like to get it done before January 1st 2019

Cheers

Hi Ian

Your link, "Please see here for details of being registered as a Supplier" is not working. 

Does it still exist

Cheers

Yes, it was a great day for the first time event at Maryborough Airport and the word is; it could now be an annual event.

Congratulations to all the organisers and helpers for a great trouble free day out.

They're only available to European customers

"Delivery of complete 2-cylinder 4-stroke HB Boxer engines engines (import and export within Europe)"

At Maryborough Airport in Queensland a New Military Aviation Museum has been formed and we are looking for any aviation material you may have hidden away in storage somewhere.

If anyone has any parts of aircraft or airforce memorabilia pertaining to the Maryborough Wireless Training base during the second world war, please contact me by PM

One main aircraft that the museum is focusing on is the CAC Wackett Trainer, so if anyone has a spare plane sitting in their old shed (any condition is OK) or any parts from one please let us know.

Any donations of memorabilia would be greatly appreciated as this is a not for profit organisation.

I'm looking for a secondhand Ballistic Recovery System for 270kg or 350kg size that has never been deployed but may need repacking.

If you have one you would like to sell let me know.

Would there be any qualified or university students involved in Aerospace Engineering who are members of Recreational Flying and could be interest in working on a special Aviation project.

Located in Queensland would be good; Sunshine coast to Bundaberg would be better.

It may lead to new innovations in the aviation industry.

This is the same phone number used by the scammer, looks like its from Romania

Always ask for as much information as possible and in the case of an engine; the serial number.

Then you can give Bert Flood Imports a call and they will tell you who owns the engine and where it should be located anywhere in the world, not just Australia.

You should treat every advert as a scam until you have checked all the details, serial numbers included.

Can you give us a good clear photo of the AMP sticker on the bottom of the unit; are there any serial numbers on it?

I don't really know, I am guessing it is a HUD; but with the airspeed and altitude being low I would say it maybe used in a cropduster aircraft or similar.

They're one aircraft you can't afford to be looking down at instruments all the time when doing regular tight maneuvers.

It's only a guess.
