Hi The bearing OD IS 1.975 od 1.050 id thickness is.565 What I was told by BJ Schramm is that there is more load on the Helicycle bearings than the Rotorway because of the increased RPM 615 the Rotorway and Helicycle bearings are made the same other than the ID and OD slightly different Doug

Hi All The helicycle bearings are still made by the origional manufacturer Randolph Research. The same company who does bearings Rotorway. There was never any talk about Rotorway manufacturing bearings for them self or Helicycle.The supply problem was that they will not sell to anyone but...

Hi All One thing people do not realize about HP ratings is there is about a 15% correction factor added into the HP ratings tor temp, altitude, humidity, friction losses, ETC. so in the real world if your engine is rated at 100HP real HP is going to be 85 For example we dynoed a GM LT4 crate...

Yes I have the pair Of helicycle blades Thanks Doug

An article at Skybrary states that for a vortex ring state to occur: Now it makes sense because one of the ways to get out of VRS was autorotation Doug

Hi All correct me if I am wrong. I also thought no way untill I stopped and really thought about it. to create lift there must be a downward flow of air. without a downward flow of air there can be no lift. in autorotation there is a downward flow of air creating lift otherwise we would just...

Hi All The first thing I see is they are extruded aluminum. Back when the fleck blades came out there was concern about them.At that time the only alloy that could be extruded for blades was 6063 not 6061 and definitely not 2024 the fleck blades did have a slide in glued in leading edge spar...

Hi All took a look in my collection I have an R22 upper pulley and shaft with the sprag clutch assy $700.00 plus shipping if someone still needs one. Less than half the price of an MO300A Doug

Hi All I think in my collection of parts I may have a R22 pulley, shaft and sprag clutch assy if someone still needs a clutch I can take a look and see if I still have it. Doug

Hi All I believe that the reason we post our work is to get input from others. Your workmanship looks really good. This is just my opinion. I think that the mini 500 transmission and rotor system is going to be too small for the size, weight and power plant. A winters non quick change with a...

$600.00 Looks like it has ben fabricated up may require more work Doug

Appears to be a scorpion 2 rotorhead. It came to me along with a scorpion 2 helicopter I purchased long ago.The gentleman said it was being converted from cable style to elastomerics looks to fit a1.500 inch rotor shaft, ill add a picture once my camera starts to cooperate with me Doug

Hi All Composite blades are being tested on a Rotorway helicopter. I spoke with the blade designer/manufacturer a Oshkosh. He stated that the blades are overbalanced at the tips. So there is less weight at the root end of the blade. This puts the span CG further towards the tip of the blade...

Hi All I agree 99% with sky guy. gear boxes and turbine housings are interchangeable with a lot of the T62 Series engines. I have used T39 turbine sections on both a 16B and T2A1 The T39 was less desirable than A 16B or T2A1 but the turbine sections are the same (not including the burner cans)...

Sooo you have never worked on a T62T32 or 32A interesting. . The T32 is the more desireable engine for helicopter applications. The T32A not so much. lets just say it is because of the extra weight, not because in our helicopter community (that you have just joined) it has a reputation of high...
