No, I have used that. A horrible program had come in with a photo editing program that I was trying. "Malwarebytes" fixed it for me...........

Oh so sorry. I just "updated " to windows 8. and I'm getting these pop ups everytime I use password manager. It must have come in with that...God I hate those buggers...So Sorry again!

It can be stretched into unreliability!

What's with this Woolworths "pop up" scam ? The sooner that goes the better this site will be...

Dear Bex .....don't feel offended or "got at" , People are full of interest for your engine. We are all willing you to succeed.........................You have as much right to comment as anyone else here.....

Unfortunately, wing fold (somehow) and trailerability are 'must have' options as much as I don't like it. A 28 foot airplane weighing 100kgs costs the same in a hangar as a Cessna 172...And , these days that is $100 plus per week....Neither am I altogether in favour of Alu. covering. The handling will cause lots of "hangar rash" which will spoil it quickly.......Is a fabric covered alu. wing possible?

It's not worth the effort to cut the VW c'case. It works just fine with covering plates over the 2 extra holes...........

I thought the 1/2 VW was a good idea. VERY cheap, lots of good bits available. All "do it yourself"....They look great and perform well on the "Legal Eagle"

Dear Dmech. Yes the barrel crack was on the oil filter side, the bolt broke top front l/h side...

No Oscar, no witness marks. My best guess is that the barrel broke first, then the bolt....Detonation? again...the engine was (2200) 20 hours old...I hope that the CASA intervention can encourage J. to find a cure and stop this sort of thing from happening again.

Note: the crack in the barrel was well above the base. probably 20 or 30 mm. Nothing to do with the radius... But it was on top of the barrel....Tell me again which happened first? ...................

quote " jetjrWhat about cylinder cracking mentioned in the instrument? Anyone ever seen this " Yes, first hand, several occurrences............. Happens in conjuction with broken through bolt. Before the bolts breaks or after? who knows? 2 on engines immediately after rebuild. ( By J) Forced landings each time....

The $13.50 for a coffee and a tea at the airport,is NOT a result of price gouging by the seller I'm sure , but a reflection of the amount of rent having to be paid by the retailer, plus penalty payments for the staff. ......Airports are good business! For the owner...........

BS....They are both aero engines , both claim to have a engine life of 2000 hours, both should be as reliable as humanly possible given an economic framework. They are two different types of engine in one way though. One works the other doesn't

How could anyone expect a qualified workshop for $50 per hour? My Merc guy is $108.. I was charging $65 per hour when I closed my shop. 10 years ago...(and I still found it difficult to make a quid .Due to gigantic overheads I must add)

I just saw a video of the Italian MW motor. That is really impressive with complex die castings and all the modern fruit. Lots of HP (up to 150) and not too heavy. Looks like ohc... Apparently fits straight onto 3300 Jab mounts! Plus the 6 cyl D motor 3.6? ltr in production with 135hp lightweight/sidevalve too. Also a direct fit on Jab3300 mounts. Sounds like vultures circling to me......

I always admired the "Airbike" and the " Legal eagle" types But living near the sea the wind might be too much for anything like that except for early/ late flights. When I think about it , that's what I do nowadays. hmmmmmm

The video is of FAI speed . Two lines. 2.5cc , straight methanol and castor oil. No nitro. The aircraft is "whipped " up to speed and when the model comes "on the pipe" (tuned length expansion pipe ,it's a two stroke remember) the pilot put the handle in the cradle for 1 km....I don't know what the record is now, But it used to be 250+ kph...The model is asymmetric to cover as much line as possible to reduce drag....Fun to do....

Put them at Mangalore

If you want an efficient engine developing more than 30 or 40 bhp per litre .............you will have to run it at more than 2700rpm.... That's a fact...So A modern motor will have to be geared....Where are all the motorcycle engined wonders? they're all over the sky and they're called Rotaxes....100hp from 1.2ltr......I just don't have the time (anymore) to develop a crankcase to take m/c parts.....I wish I did....

Correct of course.......................... BUT A high bhp/litre figure is a good measure of an engines' efficiency. Torque figures are redundant as we are always talking about geared motors. Thus the ability to turn a large dia prop is always present. Fuel consumption will be the same...you need to burn fuel to make power. More fuel =more power. (within reasonable parameters.) or more interestingly, more power=more fuel. We are looking for light weight and reliability. This is the domain of modern motorcycle engines (with exceptions) Reliability is ,these days, always present. If the engine is configured to run at 50% or 75% of max output constantly makes not so much difference....Cooling will be the main reliability factor. Bex recommended the GSX/Fj1300 series.. The Bandit 1400 looks better to me being oil/air cooled and fuel injected. 106hp @ 6800 rpm.... Gotta lighten it though..........Cut the gearbox off, drive from the alternator end of the crank, belt drive the prop shaft.(Don't forget to to get rid of nasty side loads). Should run at 4500rpm all day.(oops, sounds like a Rotax!) ...I wish I were younger........

in a previous life I built speedway 3/4 midgets engines in NZ. We use single ohc Honda's running 14-1 on methanol. Engine was mounted north south with shaft drive and diff. The point is we cut the gearbox off and welded a plate on the big hole and took the drive off the l/h end of the crank. Never failed!..... They were quite light....Because your situation is special you may have to do it yourself....Big Job though...

Of course. because it is an adaptation.....aviation is too troublesome by far to get an auto manufacturer on board, there's more money in cars, That's why we wait patiently for Bex.....Although the "Take off" 1200cc Beemer would make that 2200 jab of yours look like a seriously sick slug....But 160lbs...

My goodness that old chestnut again..............I've said it so often..My 0-200 is the pinnacle of light aviation engine design (well, almost.) it puts out 80 odd hp for 3.2 ltr @ 170lbs ....It can run at that 80+ horse for quite a long time non-stop. But so can just about every other (real) engine made today! The poor old Continental is producing about 25 hp per litre....So it should bloody well run forever it's not doing anything!!!! Jabiru is the same....Lazy old lump of an engine..3.3 ltr and 100 horse constant.....There are modern motors that IDLE faster than the 0-200 at max revs. ! and that's not a joke....All this bulls^^it about only running at 30% power. ( auto engines) That's just a result of the state of tune. If an automotive engine designer saw a requirement for an engine to run at 100% for 10 minutes and 75% forever then he could just change the cam and reset the FADEC parameters and it would be ready this afternoon.... Aviations engines are NOT wonderful they're antiquated, heavy, inefficient and unreliable!.............................. ( with a bit of an exception for Rotax which was designed for something else first anyway) .....

QUOTE="Andys@coffs, post: 464060, "Even the nascar average speed of 80miles per hour" Nascar average speed is 80mph?........... Well yes I suppose it might be IF you run at 200MPH (is that flat knakker?) for 496 laps Then there's a crash 4 laps from the end and they circulate at 40mph for 20 minutes... Great statistics, you should get a job with Jabiru
