You can get an aftermarket ignition system, that has long leads, allowing the modules to be located away from engine heat & vibration.

they are on the firewall , well away from engine and exhaust.  the intake was there so i thought i would use it.

Good idea, but a hose that wide is probably overkill. I use a 25mm hose to duct air to each coil. The flow is probably reduced by a few curves and the friction inside that small scat hose, but it should be enough.
 

Does your big coil cooling air supply affect air flow to the hot bits of the engine?

its behind the engine so it should have no effect. the intake is 2 inch thats the reason its that size. it was the engine intake scoop when it was kfm powered.

that looks like a ww2 glider converted to power, i know its probably not but the fuse looks like a transport glider.   

 sorry, did not see the earlier posts.

The monoplane/biplane is a Hillson FH40 Slipwing Hawker Hurricane. A Hurricane with a second wing which can be discarded after take-off. Designed to shorten the take-off for a quick scramble launch, then discard the top wing for speed for the pursuit and fight.

 

 

not much fun if it took the tail off on its release.

i have read that rotax ign modules run fairly hot which shortens their lifespan.

so on my lsa there just happens to be an unused air intake from when it had a kfm.  i have run a 2 inch hose with flattened end to point at the 

ignition modules so they will be fed cool air when flying.  

is this a good idea or pointless.

I was thinking the propeller blades sheared of in the landing. Reading the report about increasing vibration perhaps they went fa coffee.

 

them roos have a lot to answer for.   they always have to get in the way.

No, people not reporting the accidents to them.

They will always go to the scene when they can, and these days they have access to electronic emergency reports. so can write a story from the desk if it's deadline day.

it was on the abc so every network knew about it.  nothing sensational in it for them so they did not pursue it.

Interesting thread, but still haven’t found out anything about the prang. 

I posted a link from the news. I wasn't there. If I knew more I would have posted it. It didn't seem to get much coverage. The media seem to have lost interest after so many aircraft accidents recently. Not exciting enough for them.

You don't need the choke for more than a few seconds in a 912.  Engine fires then slowly push choke back in

. don't see why you need to keep it pulled out like that.

makes sense. i did not think about it being referenced later. 

How did you change the heading of my post without my permission. Are people allowed to do this.

When posting a new thread in Incidents and Accidents, could people please include the make of aircraft if known; accident/fatal etc; date.

We now have about 10-15 years of data in this section and often, if we can pick up a previous make of aircraft or the date we can correlate similarities., or build statistics by year.

 It was posted on Facebook and I put the link here for anyone that may have been interested. I don't know anymore.  I did not realise I needed to get your permission first. I apologise.

yep

thats good.  told a few interested people to follow your posts on the conversion.

but he's  a rotax owner Don, when a set of rings for a rotax is $250, money is no object.  (I just bought 6 ring sets for a jab project for less than the cost of a single ring set for the rotax) .

are you still fitting the rotax in your jab

Once, I was taking a hang-glider guy for a passenger flight in  glider. On tow, I let him have a go on the controls cos he seemed so good. In my recollection, I only took my eyes off the tug for a second to look around for other gliders etc. When I looked back, NO TUG! in panic, I looked around to find we ( the glider and tug ) were formating wing-tip to wing-tip. ( about 1500 ft ).

I sure learned a hard lesson from that... you never assume too much I learned.

But was not that glider collision the result of them entering cloud?

it was just a thought, its hard enough to see another plane with perfect vision.

No lenses supplied here....  anyway, I use the 1.5 magnifiers from the cheapo shop. They used to cost me 3.99 dollars. Probably gone up now.

BUT the cataracts were done by a good guy and now I can see the leaves in the trees and other planes in the sky. Best operation ever.

this post makes me wonder if what is being discussed here could have been a factor in the glider collision a couple of weeks back.

Hughes I think they just said

should be on the news tonight. no injurys as far as i know. a chopper is supposed to have crashed through a house roof in mentone this afternoon. i assume it would be one of the trainers from moorabbin.

Due to the locating of the Rotax 9 carburettors/inlet air, above and to the rear of the engine,  carburettor icing is (in many installations) a low risk due to ingesting warm air from the engine bay.

 

Turbo charged varient have even less risk of carby icing as inlet air heated by turbo .

 

Fuel injected 9's don't have the venturi/fuel vapour condition present in a carburettor, so are also resistant to icing.

 

BUT

 

If your instillation has ambient (cold) air ducted  directly to the carby's the risk of icing increases, so in these installations carby heat is often designed in.

i realise the carbs on top pick up warm air, the tecnam will ice up a little bit when starting on a cool morning but  comes good after a minute or 2. mine probably will too. i did not think about ducted air , used to looking at the filters on the carbs.

front more black then rear ?

enrichment circuit not slightly on ? I have heard of Bing carb enrichment shafts getting a bit sticky with the rubbers- causing enrichment never to truly  disappear and runs hell rich. remove and pollish enrichment shafts  and reinstall.  No accidental carb heat ? no mouse in the intake ducts ? EGT drop on carb heat applied? EGT does as expected as WOT and as expected (gets hotter ) at cruise throttle ?

Carb heat on a rotax ?. Mine doesn't have it and the tecnam I have been training in doesn't either.

another gear up landing. gather the empenage buckled when the front of the airplane stopped.  cant imagine the passengers bodies faired well to the decel.

Technically they haven't really touched down yet. It's still in the air.😁

I agree with jack. Part 103 seems to be very popular in the USA ATM. There are quite a few factory built kits and aircraft to choose from. Someone must be buying them.

looking for aerochute flyers and would like to know if there is a better forum. this one looks like it has been quiet for a long time.

looks good.  i am  getting an aerochute for the same reason, easy to store and can fly out of reasonably small areas. will have the jab to go places and the chute just for fun on calm mornings.
