    Rotax-582 mounted vertical?

    I was recently asked by local homebuilder who wants to install a R582 in his ultralight helicopter design. The question is if there are any troubles expected/guaranteed if he installs this engine (without gearbox) with crankshaft vertical? Surfing the Net gave nothing to the moment. The only...

    New propeller for 914UL MT-03 / MTO Sport ?

    Kool props are that same Luga under another name ;) A guy who offers them lives mostly in Canada.

    New propeller for 914UL MT-03 / MTO Sport ?

    Just a small remark: there are some sellers there who offer same Luga props under various other names =) One example is here on the forum: https://www.rotaryforum.com/threads/selling-3-bladed-carbon-fiber-propeller-right-rotation.46108/ He even uses photos taken from Luga website painting out...

    I'm coming to the dark side

    Kit or plans-built hardly can give serious saving but are time consuming. If you have no experience in homebuilding nor good workshop for this then it can become (very) long story. Spent a bit more time getting more familiar with gyros around to see what are possible nuances. Visit Blois and...

    I'm coming to the dark side

    I'm aware that this number is only possible if you're lucky to meet somebody who is going to get out from the game or something similar. 2-3 years back my fellow in Portugal was lucky to buy a good Dominator for that money. Any other choice means rotor+engine+prop which together hardly can be...

    New propeller for 914UL MT-03 / MTO Sport ?

    There is still enough clearance for a 175 cm prop, Erik. Most of German gyros here in Russia fly with these 175 cm Luga props. The thing is that you'll need another spacer to install such prop since it has 75 mm bolts pattern. I also use to make these spacers a bit longer than standard HTC...

    New propeller for 914UL MT-03 / MTO Sport ?

    Erik, Original HTC propellers are real junk, that is. They won't last long and there were many failure reports on them. I tried different props for gyros and found (well, to the moment) that the best for the money would be Luga Prop. It has good thrust at low speed (for efficient take-off and...

    Getting no-name critical parts

    There is a guy in Portugal who built a Gyrobee from plans some years ago. He had exactly same issue with EU Spruce ordering rod ends from there. Looks like there is somebody in this company who simply doesn't know the difference and importance of these parts quality. In my 20+ years history with...

    I'd rather say that it was a 3M adhesive which had issues with this manufacturer =) Could you tell us a bit more about this attempt, Brian? I never heard that somebody in the UK tried to build metal rotors. I also wonder how this could pass through the UK CAA which probably is even more...

    Pre-rotator torque

    Different rotors make very big difference in prerotation power required. DW rotors with their positive twist need much more than any non-twisted rotor of the same size. I once replaced standard Xenon 8.40 rotor and installed DW on this Xenon to see what would be the difference in flight...

    It is always good to see when a serious project is starting that way - with initial highest care and attention to details. I'm sure most of us wish you good luck Denis.
