John and all the MA guys... a question.

-Seems like that fan was far out of balance. I know there are after market fans and do you think they would be closer/better/more suitable then the stock fan?



Looking forward to the next section of the video!!

Don't know - unless they were specifically balanced I don't see how they'd come out the machine shop much different from the MA item - read a thread on another forum where the guy had taken out x4 1/4" divots where I'd used x7 3/16" so I guess it's about the same - no big deal - not difficult to do and you can see the benefits even on the balancer.

But Im enjoying the hell out of these videos.

Keep it up!

Lower half frame completed - Fuel tank installation and fan shroud - $64 question as to clunk and weight - I elected for Hayes clunk tubing and an OS bubbleless clunk rather than the supplied MA fuel magnet and clunk line

I am currently using hayes and the bubbless clunk in my Stratus. I was previously using the fuel magnet but it fell apart and I didn't have any replacement foam. It worked great until then

DOH! I just ordered stuff from Readyheli and was THIS close to ordering Hayes clunk line. I guess I'll grab Hayes and the OS clunk. The OS clunk doesn't need maintenance?

Thanks for the videos! Mine's starting to take shape.
Did you have a hard time locating the MP5? All US dealers have been out of stock for awhile.

Thank you for these videos. The info contained is very useful for any heli build. Will you be showing a flight video at the end? Again, thanks a million.

No system's perfect and I have heard of probs with the Hayes line swelling and falling off fittings so a couple of ties might be worthwhile - haven't heard of probs with the OS clunk but I'm sure some people have had - Found the MP5 no problem - you have to shop around Asia / EUrope / US to find bits though - thank goodness for the internet !

Question for you guys about the fan. just bought a somewhat used stratus with some aftermarket parts and i'm not sure which are upgrades and which are stock. When i installed the fan it seemed to balance fairly well, however the collets just will not fit into the fan. the fan which i think is an aftermarket part has a groove for a woodruff key which i'm using instead of the collets. seems to work fine but does anyone else have this problem?

The collets are crucial for centering up the fan and also gripping the fan and shaft to transmit power (in your case done by the Woodruff key) some after market fan manufacturers make their own collets which I would think essential. Other problem is that there have been some subtle but relevant changes in OS motors of the same model which compounds the problem - if yours balances and dials OK then I guess it's fine but if not I'd buy a new fan & collet set.
