  1. Orphan added a post in a topic NEXT QUESTION - WHAT'S A 670?   

    I have the drawings done and they will have a moveable elevator. It will have a small travel distance but the response will be significant. If you ever have seen what Peterson does with a 182 at about 35 knots you will be impressed. I am using the same or similar design and will mount on a strut under the engine and mounted to the top motor mounts. Everything will be carbon fiber with aluminum skin attached over it. Very light  and wont add much for weight ahead of the center of gravity. It does take a huge load off the tail though.

    Yea I am around Dickinson, have been here for about two years in this area. Doesn't seem to be an end to it yet, just keeps getting bigger and bigger. Time off has been getting smaller and smaller too, but cant complain about the money.

    I have stalled on the installation because work has me away from home this year. Hope that this fall eases up on me and I can get it completed. I do know the exhaust system is going to be a challenge being a much bigger pipe than the 582 was. I am also going real experimental by working on a front canard similar to the Peterson Katamei. I hope to be able to decrease the angle of attack on approaches and decrease the stall speed considerably. I have the drawing done and trying to find some with a cnc router to cut out the ribs from carbon fiber and slim plywood composite. I have the wide gear from Airdale and will be putting on Airstreak and Grove wheels and brakes. Just can't get away from work long enough to get anything done. Oilfield has me hostage.

    I just purchased one from Rotax Rick in Florida, it is basically a 582 with bigger bearings in the crank, a 670 case from a SkiDoo snowmachine. It has 582 heads and dual ignition from the 582, rave valves on the cylinders, same water system as the 582 blue head and the crank is milled to fit the gear box. With stock 582 exhaust it will yield about 65 to 66HP and with the tuned exhaust he says about 86hp. I will find out when I get mine in the air, I have the tuned exhaust and hope that it lives up to its reputation.

    Thanks,
    He got in touch with me, going to go that route with my setup. I have the wide gear from Airdale already, getting Grove six inch rims with 1.25" axles and dual 1.75" pucks on the calipers. These will go one the Airstreak tires from Alaskan bush wheels and I think that will do. I am hanging new 670 with tuned muffler for about 86 HP and all this on my Mark IV. Will post some pics when I get a little further along with the re-work. The plane is in excellent condition prior to doing this but 582 had 300 hours on it so I thought it was time. Here is the before pic.

    Do you have a way to contact Micheal so I can purchase a set of these brake pedal mod's, I am reworking my Mark IV with new gear and new brakes. Would like to add this feature to allow more brake authority on bush wheels.
    thanks,

    I have the same problem, I am installing a new 670 and my mounts are bad. Been looking at Aircraft Spruce but there are so many that I cannot figure out which will fit, beside the price is sky high. I will be following this thread and hope someone else has the answers and location for replacements.

    What are you using for injection on the 582, I was thinking about using electronic injection systems they use on motorcycles. Here is the link http://www.ecotrons.com/2_Stroke_Small_Engine_EFI_kit.html I dont know if its something that will work properly or not. Could you let me know
    Thanks,

    I just got a quote from my insurance company for 850.00 per year for my Mark IV i just bought. I also have another aircraft insured with them so I dont know if it makes a difference in the price or not. But you can call my agent, his number is:

    Jeff McClaran
    877-353-1047 office
    816-309-4104 cell

    He will answer anytime his cell phone and is very helpful. They have monthly rates or yearly which ever you prefer. A good bunch of people. The company is Aviation Solutions, Lee's Summint, MO

    Well thanks for all the info, it has a heavy hauler wing on it and a 582. I have a Tbird II also and its really squirrely on the ground and not to bad in the air but is still a hand full. I just dont feel comfortable in the Tbird, not enough air frame around me and too big of a wing. 36' wing span and 18' long, can't hold it down on the ground when the wind is blowing, which it never stops in South Dakota. As far as speed 95 to 100 is just right for me, want low and slow for watching critters along the Missouri River in South Dakota. I have lots of flat grass lands and river bluffs to play around in so its going to be a lot of fun. My Maule is great flying too but I wanted something slower and cheaper to fly chasing coyotes and things around the patch. Talked with Bret about the wide gear and found grove wheels and Air Streak wheels to fit 1.25 axles on the new gear and hopefully that doesnt mess up the weight and balance on the bird. Any suggestions on that?
    Thanks,
    Ole

    Well sounds good. I have just bought a Mark IV and haven't had a chance to get it home and fly it. I own a Maule MX7 and it is really docile on the break and easy to control with rudder. Hope this one flies like it too. Sounds like its going to be fun.

    Has anyone had any experience with spins or how this bird reacts prior to a spin Entry?
