CF

Quote 
I would never use CF/ tail blades. CF tail blades are to rigid and do not provide any Dampening to the tail rotor assembly. they also contribute to quite a bit of High frequency vibration in flight not to mention huge amounts of RFI.


I disagree. If you have a vibration in the tail you should be looking for out of balance conditions. I have run CF tailblades on everyheli I have owned and never experienced a "high frequency" vibration that was a result of a composite tail blade exclusively. Plastic or CF it doesn't matter. For that matter maybe we should stop using CF mainblades. Maybe that is what is causing RFI problems on all our helis.

Carbon fiber mainframes can be a real pain. On the Vigor CS kit you get a brass shim that grounds the lower and side frames together. If it is not installed correctly you will still get serious RFI issues. On the otherhand, my Raptor 60 has carbon fiber frames. They are NOT grounded to each other or the carbon fiber boom. Guess how many glitches I have had on it? ZERO So, what I am getting at is depending on the blend of carbon fiber/plastic or carbon fiber/metal in these kits would tend to dictate how likely you would experience RFI.

You bring up some good points. Although, the CF tail pushrod is smoother, direct, and light. It doesn't vibrate nealy as bad as the metal flimsy stock one did. I always try to stay with the stock tail rotor pushrod system but if I cannot get it smooth and STAY smooth then off it comes. I now get better gain and smoother operation in the linkages and that is what it is all about. Nothing more, nothing less.

We agree on the header tank issue. Shewwwwww!

Mixing Ratios

Stephen,
Don't worry, my panties did get to high up there. And, I agree that the Falcon tail is not some bust in the design. My bone of contention is that this is a sport pod-and-boom ship designed for aerobatics and is certainly 3D capable. It is even marketed that way. The tail pitch is not symetrical which leaves the user with a potential issue to sort out if they wish to push the heli in 3D. Also, I did mention in my topic in this sub-forum regarding the tail modification that it is not for everyone and to build the kit stock and take it from there. I try to give everything a fair shake and get a feel for what the manuf is trying to achieve with their stock configurations. You do actually have a good point there. I guess I took it personal and shouldn't have. I have a pretty good grasp on the GY 401 now and thought you were degrading my setup skills when I should have been reading your post in a more general sense.

Also, I couldn't agree more. And I hope that the newcomers are listening to you. Just because I or somebody else says a set of blades, paddles, tail component change, etc makes their machine scream doesn't mean that they are necessarily required to get it. I know I have fallen prey to upgrade-itis in the past. I would agree it is best to stay with the fuel burning upgrade recommendation and encourage those in the early stages to stay with the basics. I just wanted to share my experiences for those in the 3D crowd that are overlooking the Falcon SE II.

I forgot to dig into the issue of mixing ratios. Unfortunately I have not developed enough understanding of them and how to derive the ratio itself. Could you expand a little on this. Maybe in a new topic here in the Century sub-forum.

As far as the pics please do share them. That is what these boards are all about. Sharing experiences both good and bad. I can promise you that if it weren't for RunRyder and a few other online boards I would not have advanced as far as I have in such a short period of time.
