    You don't need luck, it's very simple. You just need confidence from doing a few (hundred). Regards, Jeff Read this topic online here: http://forums.matronics.com/viewtopic.php?p 6157#206157

    Subject: Carburetor Ice?
    Hi Guys What are the symptoms of carburetor Ice and has anyone seen it happen with the 912uls 100 hp engine Today I had my engine speeding up and slowing down..When you increase the throttle setting the engine was like it was runing out of gas.But I had half tanks .i was about 5 miles from the airport so I reduced the power and set up a glide for the runway and got in ok ..I was at 3500 ft so I had lots of glide range as I still had power. The engine did not stop and I landed ok. I had this happen one time before when there was about 20 hours on it.I have 128 hours on it now .It slowed like it was going to stop. It was pulsing and increasing and reducing the power..I thought it might have been where i was on a long decent and the gas was not covering the outlets from the tank so it was sucking air..It is not a nice feeling when this happens.. What should I check to solve this problem.. I saw some dirt in my gas filter today so I will replace it..There was no dirt in it when it happened at 20 hours... any help would be appreciated... Alvin Rose Marystown, NL. ajroseca@nf.sympatico.ca

    Subject: Re: After 5 hours flight time, questions
    I had my BRS mounted similarly to where your is, only on the front side of the firewall. The DAR warned me that the CG would be too far back, and although the plane was well built and perfectly safe in every other way, he insisted that the BRS be taken out and weight added forward before the first flight! Being stupid and stubborn, I thought I knew better and flew it like that, and though I hate to admit it, I almost paid a heavy price for doing so! The plane was almost uncontrolable at low speed, and I finally got it on the ground, but when it slowed during the flare the nose took off like a homesick angel and then slammed down on the turf, flattening the front fork. I made several passes at the runway, using every bit of skill I had gleaned from 3,000+ hours of flying everything from ultralights on up. When it slowed down the nose raised, the tail dropped and it became so sluggish it was virtually uncontrollable! Very unsafe, at least in my airplane! I now have it mounted immediately behind the pilot/copilot seats, so that one can use it as a head rest. I also moved the battery forward to the front of the firewall to try to move the seriously aft CG forward. Now it flies OK, but I'd be really concerned about the placement of your BRS! The only thing I had changed in the tail to move the CG backward was X braces made of L angle aluminum as an anti-oil-canning thing, but this probably wasn't of too much consequence. Basically the placement of my "safety" chute almost became a "killer" chute. I hate to admit how stupid and arrogant I was regarding the CG, but if it saves someone else from making the same mistake, what the heck........ What was unsafe in my plane MIGHT be safe in yours, but be very very careful! If you keep it like tht, be awfully sure of your weights and your calculations regarding the CG! ----- Original Message ----- From: Les Goldner To: zenith701801-list@matronics.com Sent: Monday, September 22, 2008 9:11 PM Subject: RE: Zenith701801-List: Re: After 5 hours flight time, questions Thanks guys for the advice regarding sending pics through matronics. I have attached two pictures taken during the construction of N67MG that show the reinforcement to the baggage compartment back wall used to support my BRS chute. The reinforcement consists of some big gussets with Ls on their sides, and horizontal Ls top and bottom. The heavy vertical Ls close to the center hold the chute. Also, see the full-height cargo door on the pilot side of the compartment in the pictures. I can get my 20# folding bike through this door and have cargo nets forward of the door so nothing heavy falls to the back.

    Subject: CH701 Wing Leveler
    Les Goldner, Since the matronics 601 group have been having the discussion on AutoPilots, how has your wing-leveler been working out with your 701? Any inverse-yaw actions? Just curious, and hope you are making sure that there is more air time under your tires than ground time :-) Keith CH701 -- scratch -- finishing up rear fuselage, ready to finish cabin sides, and work on forward fuselage.

    Subject: Re: Carburetor Ice?
    Alvin. The Rotax 912 ULS comes with a manifold for carb heat and cold air intake. It insures that you get the full 100 HP you paid for, by supplying cold air to the carbs and to supply heated air for carb heat. Did that not get installed on your 701?
