I wonder why they're not needed on the GU canard.

I think people have mainly been commenting on the generalities of such accidents and who may or may not be responsible for damaged or contaminated runways. Probably would have been better to change th

But they're available free online.

What about this - http://www.geareddrives.com/PSRU_for_Subaru.htm

It's a Q2 so GU canard and no sparrow strainers?

I suppose numbers are declining even allowing for new completions and rebuilds:(

I say it's more efficient. From what I have read the only reason it was changed for the Ls1 is because of the contamination issues which can mainly be solved with VG's anyway. I agree that the LS1 is

Hi. Why replace the GU? It is strong enough for a 912, and more efficient than the LS1. If you are worried about contamination then use VG's. Allan

But less efficient? (so long as it is kept clean;)

I think all non-certified Rotax engines carry that warning. My four stroke 912UL does. Allan "The Rotax 582 operator's manual stated: ' Danger! This engine, by its design, is subject to sudden stoppag

Hi. No it doesn't know how fast it's going, but it "knows" how much load is on the propeller. When the prop/engine is unloaded it can cause high egt's and a seizure. The condition is more likely to oc

Hi. I'm not sure why you mention the "up down right or left" bit, I wasn't saying anything about engine position. I am saying that 2 strokes are known to be more subceptable to seizing on a fast/slipp

Hi. I have a Rotax 503 in my Challenger, but from what I understand 2 strokes are prone to seizing if you use them in anything that is fast/slippery. Allan

I saw a boatbulding book once and the author (may have been Allan Vaitses) said that any high stress incident (heavy landing/loading test?) reduces the overall strength of a fibreglass structure. I ca

My Q2's in bits in my garage so I won't be going near any clouds in that. Maybe in my Challenger though, fabric should be safe (just kidding) Regards Allan Sent: Friday, October 29, 2010 3:56 PM To: Q

Just out of interest - I presume a glass (warm) aircraft wouldn't be so prone to icing as a metal (cold) one? Allan Sent: Friday, October 29, 2010 12:09 PM To: Q-LIST@... Subject: [Q-LIST]
