Got a report yesterday from a customer in WA with a CTSW who replaced his factory Neuform prop. He is pretty happy

 

• Pitch 27.2º (within 0.3º specified tolerance)
  
• Test carried out without spinner
  
• Conditions (approx.)
  
  • 1022.1hPa
    
  • 14º
    
  • Wind ESE @ 11kts
    

  [*]Load

  • Two pax
    
  • Approx. 60l fuel
    
  • 10kgs water ballast
    

  [*]Run-up info

  • Oil temp 150º
    
  • CHT 170 º
    
  • Oil press 25psi
    
  • Idle RPM 1650
    

  [*]Take off

  • 15º flaps
    
  • 5400 WOT @ 65kts
    

  [*]Climb out

  • 0º flaps
    
  • 5400 WOT @ 85 kts building to 90kts
    
  • 1,000ft/min
    

  [*]Cruise readings

  • Oil temp 200º
    
  • CHT 165 º
    
  • Oil press 50psi
    

  [*]Cruise in sequence @ 1700’

  • 4200 @ 90kts
    
  • 4400 @ 100kts
    
  • 4600 @ 105kts
    
  • 4800 @ 110kts
    
  • 5000 @ 115kts
    
  • 5400 @ 125kts (This was only held for a short period but we believe the speed could have continued to increase at this throttle setting)
    

  [*]There is a noticeable lag when throttle is applied rapidly – it’s only momentary, but noticeable. We think this may be a characteristic of the high aspect ratio producing momentary cavitation. It’s not problematic, especially as all of us use gradual throttle increases.

  [*]Given the reduced swept area of the props, it may be that the breaking effect on final is reduced – again, not a problem but requiring a bit of relearning.

We are very pleased. It’s going to improve marginally with the spinner. Also, we stripped the sealing tape between the wings and the fuselage. We know from previous experience that when it’s replaced it will effect the speed by at least a couple of knots.

 

 

 

VERY pleased with the results. The system definitely exceeds our expectations,

Any comparisons Mark.

I was pax in a R22 cattle mustering. Surprisingly it had a Lap Sash. Not very reassuring. couple mil perspex to hold between thumb and forefinger for added comfort. Forces kept you in the seat though.

I use 9v batteries commercially. I dont buy Eveready or duracell any more, too dear. I prefer Woolies and Coles own alkalines also AA and AAA. Aldi comes in 3rd.

I was realy cheesed off but I bit my tongue and didn't say anything as the Thieves stole my gate. I didn't want them to take a fence.

I remember going to see the first one land in Brisbane with Mum and Dad.

But the headset can do it so you must do it! That is how tech works. The call was important anyway, it was my wife!

Had to get Milk ?

I heard a sweet Rotax go over a short time ago.

Most of us are desk bound for the next few months and scratching for mental stimulation. We have a facebook group "Aerochute Flyers" with 138 members with content added most days of local flights. Anyway if interested google/search the above name and request to be a member

Ian, if not PC please remove.

Not the diesel version im guessing 

With the investment and technology in this type of aircraft would it carry the black box. 

A tragedy upon a tragedy. Alf said it beautifully above. RIP brave Aviators. 

I wonder seeing the DC10 fly through the smoke and debris the effect on the engines and the prop turbines of the like of the C130. 

if they were to build an aircraft for this purpose from the ground up what would be it’s configuration and power plants.

Caught in the Act

My Uncle, middle row, 2nd from left. 129 sqn March 1944

Crashed 2x Spitfire and was shot down DD+1 Mustang III FX959, survived.

Heard 5 aircraft fly over this afternoon in formation including some Bi-Planes and remembered there is a gathering of de Havilland aircraft at YCAB tomorrow. Copy of email sent earlier this month.

Can't see the Rotor anywhere

It is ironic that the steel salvaged from the wreck of R101 may have been used to build the Hindenburg.

Interesting bit of History.

Give me an electric setup for my Drifter, that can give me the same performance as my current Rotax 503 DCDI, at a cost roughly equivalent to the 503 and keep me in the air for a minimum of 1 hour and I will fit it at the next engine change... At the moment, it looks like my next engine may have to be a Hirth,  

3202 2 cycle 55hp  

 

or the, 3203 2 cycle 65hp both engines are free to air or fan cooled!

The fatal chopper crash that changed Australian aviation history

WWW.ABC.NET.AU

The accident was witnessed by many and widely reported, creating intense pressure for something to be done to improve safety in the skies.

"After the crash, aviation safety authorities changed the laws so that single-engine aircraft and helicopters were no longer allowed to fly over built-up areas, but had to follow waterways and coastlines.

That rule still applies today."

Interesting Statement - 

Hi Frank, that was a fair hike from your place, follow the Palmerston Hwy. Used to swim in Lake Eacham in the 70's. Used to be a Cassowary there that liked apples.
