    I have an IVO prop with the Merle Williams modification for installing the electrical connection to the motor. I am a little intimidated by the sparseness of the instructions. Has anyone used this mod. Any problems getting it to work?

    Charles , Williams prop controller pickup is great. I've been using them since about 2000. Keeps the pickup contacts behind the gearbox out of the weather. Much cleaner looking than the stock pickup Ivo includes. Nice item. Very simple but ingenious.
    Only drawback is if someone is running a Rotax vacuum pump on their engine I don't think it can be used. Murle is always happy to assist over the phone if you need him. I don't think I've seen the instructions so can't help you there. Murles' phone number is 602-978-0553.

    P.S. Our favorite aircraft kit manufacturer also carries this style Ivo prop. controller in their new parts catalog.

    I use that mod also. You need to open the electric motor, the three nuts and pull the wires out the front, than drill two holes in the cap, and feed those wires through. than at the base of the motor, outside, drill holes so you can pull the wires from the mod to the outside of the motor. Make sure you DON'T operate the motor while those nuts are off. You WILL make a mess of things.

    Is anyone flying the medium ground adjustable IVO prop on a Kitfox with a 582 engine?

    My first impression would be it's too much prop for a 582 but a quick call to Ivo would be in order. If you call, let us know what you find out.

    I heard that IVO only wants you to use a medium 2 blade on the 582 due to harmonic vibrations with the 3:1 gearbox. In fact a Kitfox that Gary Algate (Not sure if he's on this list or not) used a IVO medium inflight with his 582 and as I recall he loved the set up as he flew floats mostly.

    I e-mailed IVO yesterday and will follow up with a phone call on Monday. Thanks for the input; I'll post what I find out.

    IVO does indeed recommend the 2 blade IVO on the 582. We have sold many of them with good results. The In-Flight adjustable will definately give you the best overall performance although the ground adjustable is quick and easy. The prop controller is also available with installation instructions. If there is a vacuum pump and or the engine prop shaft is of the type 3 (can't see through the center) then the controller will not work.

    Caballo,

    I am using a Medium Ground Adjustable Ivoprop on my Mk 4 with a 582 if that is of any interest?

    PM me if you want.

    Ron at IVO prop sent the following reply.

    What is the gear reduction ratio?
    2.58 or 2.62 use Ultralight Left turn viewed from the rear 3 blade 68
    inch diameter.
    3:1 use meDium 2 blade 68-72"
    3.47:1 use meDium 3 blade 68-72"

    Not a very talkative dude, but anxioius to make a sale.
