1. ### Builder in Toronto Canada CH-640 and Bearhawk5

i think the seat being moved back is included in the newer plans...and the floor lowering mod is a must as you mention.

3. ### Yamaha 160 lb engine. 130 hp

I’ll answer my own question.... I’ve educated myself since I posted that With the most common gearbox for the Yamaha conversion...that contains the sprag clutch .... the prop will windmill at idle or if the engine quits
4. ### Can you just buy the gearbox from newer rotax motors

5. ### Can you just buy the gearbox from newer rotax motors

6. ### Canadian scratch building question mdra

Hi fellow canucks...question for you I’m eventually going to register with the mdra ... but till then... I’m building a plane with aluminum wings... I heard you can’t prime the alluminum surfaces because the mdra wants to see the factory spec marks on the aluminum Any of you that have gone...
7. ### The Prop windmilling on RX1/Apex engines

If you have a link ... I’m very interested in seeing what they found
8. ### The Prop windmilling on RX1/Apex engines

I respect your opinions..... but a wall is a wall.... doesn’t matter if that wall is vertical or horizontal ....a spinning windmilling prop/rotor will create that wall... it’s no more complicated then that...
9. ### The Prop windmilling on RX1/Apex engines

I’m not trying to be rude... the phenomenon is not well understood by many... we are all trying to make aviation safer... but sometimes on that process somebodies toes will get stepped on... my apologies
10. ### The Prop windmilling on RX1/Apex engines

I think the idea in a plane...is the faster the prop is free-windmilling ...the more it becomes a solid disk/air piling up in front of it........if the prop is slowed down for any reason...engine connection or friction....ect....then it's allowing some air to pass.....
11. ### The Prop windmilling on RX1/Apex engines

On the Yamaha Facebook conversion site...2 planes are close to completion....I'm not that familiar with the makes...but by the looks they are fast...rans...and a sonerai 2....To this point I believe most conversions have been stol aircraft...or high wing cub type planes... They are both fitted...
12. ### The Prop windmilling on RX1/Apex engines

It's counter intuitive ....but the free wheeling prop makes a lot of drag...you would not think it...but it does...and the faster the plane...I suspect the worse it gets....the air piles up in front of a freewheeling prop...not pass thru it...it creates a disk...same size as the prop
13. ### The Prop windmilling on RX1/Apex engines

Very few people here understand the problem you just posted......(plane pilots) The stopped prop heli will drop like a rock... A freewheeling prop becomes a disk....or a parachute of similar size to the prop..if it's on the nose of your plane
14. ### The Prop windmilling on RX1/Apex engines

Can you send me contact information for anyone of your customers that is using your direct drive.....I would like to get thier opinion ...I don't want to have a windmilling prop... I'd like to confirm what's going on with torsional vibrations on your direct drives... I'm asking because someone...
15. ### The Prop windmilling on RX1/Apex engines

from what ive read a freewheeling prop has the same properties as a parachute of the similar size.... Im not knocking what the yamaha communtee is trying to do...but since there has not been an engine stoppage yet...I guess nobody is intrested in this until you have to glide a plane in but...
