  1. Camguard

    Don't use it. Just stay with what's recommended and you won't be tearing down your engine early. If you do the prescribed maint. and when you're supposed to do it there is no reason you should not get 3K - 4K hrs. on your engine. You need to use a good motorcycle oil, but preferably Aero Shell Sport Plus 4. Car oils don't have the additive package that is needed and neither does a standard aircraft oil. Go rogue and pay the price later. Of course all those guys thinks it's Rotax's fault.
  2. Parachute Recommendation

    3 pulls for sure and maybe a 4th one.
  3. Why would stabilator axis bend?

    Probably hit something moving it or someone used it as a push point.
  4. Amps verses volts

    First take off the wires to the shunt behind the EFI's panel on the back firewall. Use some scotch brite on the the terminals and a dab of dielectric grease before you put them back on. There is only one big and one small wire on each end of the shunt. Then if you really want to quiet it down get a much larger capacitor than the 22K one. 22k is the Rotax minimum, but many use something bigger. The 912iS engine has 2 x 33K capacitors. It should be for 105F for temp rating, but 85F seems to work. It will be considerably larger and will need to be relocated from where the smaller 22K is now behind the engine frame. Doing both of these things will smooth out the amp fluctuations. Just cleaning the wire terminals will make a difference, but not all of it.
  5. The perfect Rotax Oil Filter wrench

    Hi Mack, How have you been? It's been a while since we've heard from you. I have plenty. Sent almost 20 out yesterday. I will say looks like lots of people are tired of using oil filter pliers, strap wrenches and the like.

    For the guys that sent a Paypal, your wrench's went out today. I couldn't respond on Paypal to let you know so I thought I would let you know here.

You will be able to ask on the spot questions and solve problems on the live engine while developing and expanding your 912 inspection skills and knowledge base. We will have classroom in the morning Saturday and Sunday (Feb. 4 & 5th) and spend both afternoons doing an annual inspection on an in-service and operational 912 engine. The afternoons will be spent in the hangar and everyone will be turning wrenches and performing task. You WILL understand a carb sync at the end of this class. JWe will have the Maintenance manual out and will follow the inspection procedures. At the end of this class you should be well grounded in the performance of a 100 hour / annual condition inspection. You will receive a Rotax Service certificate for successful completion of this class.Our classroom is air conditioned and comfortable. The hangar is air conditioned temperature controlled with a bathroom. Minimum limit is 4 students with a cap of 12. The class size is limited to make sure everyone gets to participate so don’t procrastinate and sign up now.

  9. Metal shavings in my float bowls

    You don't even have to remove the air box. Just drop it down.
  10. Metal shavings in my float bowls

    You do not need to cut or weld. Tell Jeremy to get a 1" metal washer and cut a slot in it. Then slide that over each side of the airbox where the rod goes through. Epoxy these in place. Piece of cake fix. This works even if you think it is too worn out or the hole is enlarged. Face one washer slot down and the other up. Works like a charm. Tell Jeremy to call me if he has any questions.
  11. Continued Use of Battery Charger?

    It should be a direct ground source. I would remove and clean that ground on the engine mount, put a little dielectric grease on it and make sure it is tight. I would make sure the ground terminal wires themselves aren't lose. You should be able to grab the negative wires at the terminal and try and move them. If they move then it's a poor ground. All this needs is a small washer under all the wires that sit on top of the terminal. FD made the electrical connection end too big and it slides down over the battery terminal. I see at least 50% of the CT's that come into the shop with loose wires that can be moved by hand. I haven't seen anyone have a problem with the exhaust and positive wire hook up so long as all connections are tight and corrosion free.

    Now he can go out and burn all your fuel money.
  13. 'Full Stall' vs 'Minimum Speed'

    "There's a lot of good ways to put this plane on the runway and I've decided to practice them all, just for the fun of it." The voice of reason!
  14. Continued Use of Battery Charger?

    The negative can go on the exhaust pipe because the engine ground wire is attached to the middle airframe screw and if that wasn't a good ground we would have other issues. The positive wire that hangs out the bottom of the cowl goes directly to the positive terminal. There is no real need to attach directly to the battery terminals.

    Hi Eric, Tell him congrats from me.
