    Is your remote firewall reservoir vented / plugged vent?? It needs a very small vent and sometimes it gets plugged with old dirty oil?
    Just a thought....

    +on Jack's comments, I found the hard surface vs water landing most challenging in the beginning. I nearly ground looped a couple times.....found the best way out if this happens, hit full power (it will straighten the catalina instantly) and go again. From your point of 'nearly ground looping' to flying again is very quick (maybe a second or two).
    My 2 cents

    Hey Jack, just to add to your post...
    regarding the very valid water-in-fuselage danger before take-off, I included in my pre-take off check a quick way to make sure there is no water (my bilge pump my be on and still not do its job to remove water for many reasons).  At once from idle I power up a couple seconds (water rushes rearward) and then chop the power back to low idle, at this point if there is any water in the bottom it will rush forward and I can see it just behind the fwd cockpit floorboard (a quick glance down). This I find easier to do than to turn your body around 180 degrees to look at the rear passenger floor.
    As much as I respect Jack's input (I got a lot of questions answered a few years ago, thank you so much Jack) I disagree that the rear seat could not be used by any human being....I often fly with my family, wife in the RH seat and our 11 year old (5feet tall) in the back. even my Wife sat in the back and found it roomier than sitting beside me up front...
    For safety, I installed plastic (nylon) screws in the backseat windows so that my son could kick open the rear window (at the lower rear corner) to exit in an emergency. Also the plastic screws vs metal would not damage my prop If one were to get loose...

    Hey Buckchop,
    I understand you used Oratex to patch your non-oratex fabric system. What is your original fabric and paint? When you say "light scuffing" you mean just the top coat paint or did you go back to the sun barrier coat?
    Thanks for your input

    Hey Chris,
    I agree the Catalina is best suited for us underfed people...I weigh 127Lbs and I don't find the cockpit too roomy. The good part is that once in flight you feel a sense of space as you have about 270 deg unobstructed view to the outside.
    don't worry about the full aileron control / stick hitting your leg. The aileron inputs needed are deflecting the stick maximum 1/2 in to 1 1/2 inch maximum in flight. The only time I needed near full deflection was on ground/water when taxiing to counter strong crosswinds...
    Regarding the empty weight I doubt it's 600Lbs...
    I would replace the original heavy wing sponsons for the full lotus ones...saves about 17Lbs !!!!
    Looking forward seeing more details of your new bird

    Hey Chris,
    welcome to the Catalina owners/flyers....If I can be of any assistance let me know. Even though I have a rotax 912, the Catalina flies more or less the same than a 2 smoke...
    I am just curious about 'your' new cat empty weight??? empty aircraft C of g location?

    If this includes all the wing / tailfeather materials, then it's a steal of a deal......I would buy that one if I had not a Catalina already !!!!
    There are hardly any unfinished kits for sale anymore...

    Avid Catalina for sale on ebay
    Look at this one I found on e bay. Seems a bit fishy to me....only 2 Hrs TT. I could imagine the owner having done a ground loop  and being frightened (why taking the wings off for space???They fold in minutes ). The Catalina is real easy on water but needs attention when landing on pavement. This one never landed on water!!!!!!
    Looks good though..

    Why not take a standard aircraft cable pulley?? Just take the right size and you're good to go.

  13. flywise added a post in a topic Rotax 912 trigger coil dissected   

    Hey John,
    I have looked at the Jab engine and what put me off was the fact it is a direct drive and revs pretty high.... your propeller speed is between 2800 and 3100 rpm in cruise !!! On the rotax 912 your propeller speed in cruise is  2100 rpm thanks to the reduction gearbox and that allows for much more efficiency (larger diameter propeller). Also the Jabiru engine being the same weight has 15Hp less.
    What upsets me with rotax is that they overprice parts not built by them and can be found much cheaper by the original manufacturer (Bing parts/ ducati parts/ ignition cables, NGK ignition parts, spark plugs, intake filters, fuel pump etc...)

  14. flywise added a post in a topic Rotax 912 trigger coil dissected   

    Hey Randy, I cleaned it all up, re-installed all the bits and my engine /ignition works like a charm now. You have to be careful not to break the plastic clip when you remove it and also when you re assemble the trigger you have to make sure the center pole piece is fully pushed in ( no play in/out) .
    I don't think a small amount of surface rust matters but if there has been water or condensation inside the trigger and the center pole piece is rusted between magnet-metal plate then I believe you will have a problem (less magnetism in the pole piece)

  16. flywise added a post in a topic The Magnum is here!   

    Hey Vance,
    looks like a nice Magnum. Just noticed the aircraft still on the trailer has no wing supports installed (links wing front spar to lower strut attachment). I hope your dad did not trailer it without as the wings were not designed to take the "road " beating without..
    Here a picture of my wing supports installed
    Looking forward hearing of your first fights....when I first flew the Magnum I was surprised how much rudder I needed to coordinate my turns.....much more than my Catalina.

    Hey Chris,
    you'r absolutely right, between any of the two coil wires and ground (or the wire cover metal mesh) you must have open circuit.

    Rotax 912 trigger coil dissected
    Hey 
    I would like to share my findings regarding the expensive rotax 912 trigger coils. It all started with a 300 rpm mag drop.....
    The manual states the values regarding the resistance across the winding of the trigger coil (inside the plastic housing) and when I measured mine it was within limits. Then I measured the resistance between the center pole piece and ground....I had a high resistance and each trigger had different values (there is NO info anywhere about that measurement). I thought it should be an open circuit there ....and as I am curious by nature, a few hours later I had the trigger appart to see how it is built inside. Looking at the simplicity I would like to see these triggers cost 8 $ each.......and not the 200 $ rotax is asking us.
    Also I found some of the center pole pieces to be covered in rust as there is no seal between the plastic casing and the pole piece going through. The high resistance I measured is normal I think as the center pole piece is in contact with the magnet and the magnet is stuck to the metal bracket. I actually am measuring resistance through the magnet.
    That's it for my latest head scratching activity

    Hey Pascal,
    also look at the latest rotax list of stolen engines.....it is a must when you buy second hand.

  22. flywise added a post in a topic anybody knows this guy? (possible scamer)   

    Hey Pascal,
    when I was looking for a second hand 912 there were 8 engines out of 10 not legit/scam. I found a very effective way to sort out the real vs scammers by saying I was very interested, ask for additional close up pictures. If I got the pictures I would propose to meet in person to pay & pick up the engine (or tell the seller a german friend of yours will meet him) . At that stage I would request the address and personal info. Most scammers will end the communication there!!!!!  If the engine is legit, I would ask the seller to bring it to an engine shop and have the shop take the engine, pay for it (you'll have to send the money to the shop) and crate it to send it out to you. Most shops will do it for a fee. 
     
    Hope this helps
     
    P.s I found all lower priced 912 engines to be scam!!!

  23. flywise added a post in a topic Need help   

    Thanks, I stand corrected. Great to learn stuff. I thought a tailwheel hitting the rudder would inflict more damage.

  24. flywise added a post in a topic Need help   

    Looking at your damage I don't believe the tailwheel hit your rudder. Instead I would bet someone (not clever) tried to move the aircraft lifting the tail using the bottom of the rudder as a "handle"....the only/easiest place to lift if the wings are folded.
    I might be wrong but here my 2 cents

    Just had to say it....I have no shock absorption at all on my rig (avid catalina) besides my 8.00x6 'small' tires...every landing I try/have to make it a soft one, go arounds are normal for me...
    Big tires and bush gear gives more margin for sure.
