    Rotax 582 & 670 coolant hoses...

    I won't be near my engine for another week or so but wanted to order a radiator this weekend. Does anyone know the coolant hose sizes for the Rotax 582 & 670 ? I don't want to order a radiator and the outlets not be the right size for the hoses. From what I've read on the Rotary Wing...

    How to sell my aircraft...?

    Spring will be rolling around before too long and I'm going to post my Starduster Too for sale once the weather warms up. Flight time is an issue that I'm not sure how to handle with a future potential buyer though. There are several reasons why I won't give rides in my aircraft : 1. Most aren't...

    Anyone have a CNC in their shop ?

    Does anyone have a CNC machine in their shop that could cut some small pieces out of 4130 sheet & 6061 T6 sheet for me ? Every part of my gyro,so far, has been fabricated by hand and the time consumed in doing it this way is astronomical. I need to speed up my progress if I want to fly this...

    Choosing landing gear springs...

    I'm at the point with my build of the Hornet gyrocopter that I need to choose a spring for the gear. I spoke with Dennis at Gyro Technics and he charges about $100 per spring.....ouch. I'm fortunate enough to have a die spring supplier 15 minutes from my work and I can walk in and pick the...

    Rotax 670 radiator ?

    I've been researching radiator options for my Rotax 670 on my Hornet gyro. It appears that most of the Dominator guys are using the VW Rabbit radiator. Any suggestions on radiator options? It will be mounted in the fashion that is shown in the pic.... Kevin

    Hornet max engine size.....why ???

    So,I have a question about the Hornet gyro that I can't seem to work out in my head. The plans specifically point out that a Rotax 503 is the largest engine allowed. For the life of me I can't figure out why that is. I have always had the belief that the more power you have on a gyro the better...

    Opinion on stabilizer wanted....

    So....this is a bit of redesign on my RW19 Stork and I would like some opinions. Roger used L-brackets to attach the horizontal stab to the fuselage of his original just like a TEAM Minimax does. I have a few issues with that method.... 1. A 1/4" bolt going through a 3/4" longeron only leaves...

    Prepping plywood for T-88.....

    I remember reading that plywood needs prepped before being glued with T-88 but I can't find that discussion again. If I recall correctly.....the ply is prepped by scraping with razor blades or sanding to get the coating off. Can someone expand on this....??? Kevin
