What tape should I be using with my gyro. I am using the Futaba cgy 750
I use the 3m model 411 heavy duty tape from home depot. The CGY750 likes to be hard mounted even on my gassers.

I have some of that tape from homedepot. I flew it Sunday and other then the tail jerking at little it flew fine. I order the upgrade tail rotor assembly today with a new set of blades. Ouch!! I don't want to be buying blades. I never had a problem with the stock tape that comes with cgy 750 before and have used it on Nitros with out issues. The metal push rod that comes stock is not nearly a smooth as I would like it to be. That is why I order the upgrade. Carbon rod with one guide. A much better setup. I might mount it on a trainer pod just til I get this tail vibration issue figure out. I can't afford another tip over!! Don't tell my Wife. She'll shoot me for sure. Hey honey a how much you say those blades cost!! I rather her not know!! LOL

Coolingfan,
How does your mechanical setup on the tail perform while in rate mode? Have you flown a trimming flight will all three gyros in rate mode and then save the settings?

That's what I was planning on doing today. I had everything set in my radio so I could get into a hover and then flip the switch I designated for normal mode for my tail. While trying to adjust motor the heli tip I corrected over corrected and the rest of the story is waiting blades now.

I have new question. I just got my Century muffler. I installed it. I know what the 2 small set screws are for. And I know where the big set screw goes. But how do you keep it from vibrating out. I also found out the hard way that if you screw it in to far it falls in the muffler and then you have to remove the muffler to get it out. I used the gasket from the stock muffler. Looking for advice from those who have this muffler installed and can give me so insight on the best way to install it. So it doesn't vibrate loose later. And the baffle and set screw that goes in the end. Purpose?

I don't use the set screws. They cause too many problems when you try to get the screws out. To keep the pipe tight, use some high heat RTV on your gasket and screws. The RTV will act as a "locktite" and keep that baby snug.

The baffle tones the noise down a little and the RTV treatment will help out there also. If you don't use something that can withstand the heat you will lose your baffle plug in no time flat.

Got new blades today. I'll be running Mavrik 690 flybarless sport. But grounded because of the wind. Has been gusting 25 + here today. And It is suppose to rain tomorrow. Any maybe some Sunday too. Its that time of the year. It's spring time in the Rockies. Wind doesn't usually ground me. But this is a new heli and I have already had it tip over because of higher winds then normal. So being a little more caution for now. I tried to run in the clutch today. But blades still turning when idling. Lower the throttle way down. Guess I may have to sand the liner.

Gasser update. Went to our flying site early today. Flew for about 15 minutes before the wind got to be to much! I really love big machines, as the wind doesn't seem to give them much trouble. When fueling up though. I notice fuel leaking from the tank. Dang it! I still flew anyway! Did some nice big loops. Flew great no bogging at all. Engine sounds real nice too. Order new dfc tank today. Just going to divert return line straight down. And use carb in line for filling. Just going to remove from carb for filling and de fueling. And use coil on vent line. That should eliminate fuel leak options. I am going to use a filter in gas jug. That should be ok I think.

Ok I got the new dfc tank install and I updated the Futaba CGY750 to 1.4v. Went back through setup and check everything. Now I have a question that's been bugging me for awhile. Canopy mounting? Since I have installed the Century Torpedo muffler. The front standoff on the side of the muffler is almost against it. So I can't get the canopy on with the grommet install in the canopy. So I removed it. I don't believe it will be a problem not having it pinned there. But just looks unprofessional. Any suggestions on this?

Gotta cut around it. I use a very good sisors that are a little tight so it makes a clean cut. Then 600 grit sand paper to smooth out the cut. No more problems with the canopy then. Enjoy!"Everything's better inverted"

Pictures speak louder then words. As you can see the canopy mounting post is almost touching the muffler. This doesn't leave enough room to get the canopy on with the grommet installed in the canopy. I do however have a solution. Have order micro-heli canopy mounts. Hopefully this will allow me to attached the canopy to all four places.

Move the mounting post
With that muffler you need to move your canopy mounting post up.

Move the post up, mount the canopy.

Take a sharpy and eyeball a line around the muffler. Pull out the dremel with a sanding drum and start cutting and sanding.

I'll post you a picture of where you should move the post here shortly.

Canopy Mounting
Move the mount up into a position where you can get a spare bolt into the hole from the back side. I believe those are m2's. Whatever size the post uses. I can usually get one up in there with a ball driver and not have to remove the throttle servo...but its much easier if you remove the throttle servo. Just throw a spare bolt into the existing hole for more frame support.


Once you get the post moved and the grommet repositioned, trace out the area you need to remove with a dremel and cut it out.

If yours is a V2 slim, you will also need to cut out a portion of the canopy all the way up and around the front of the pipe so it doesn't touch and melt the canopy. Just trace and cut and sand. You just gotta do it.

This pipe is an older century v4 I believe and The photos here don't show it, but there is a lot of clearance between the canopy and the front of the pipe. It doesn't touch or melt or anything. The v2 is much closer in and requires a bit more cutting to get clearance.

Once you do all this, you may find that you need to also reposition the grommets for the rear post and extend the rear posts out a little to get better clearance on the main gear.

Here you can see how far I moved the rear grommets and used some stickers to cover up the factory holes.


Here I added a couple of spacers to move the posts out a little.

I look in your gallery and saw where you move the post. What does the post screw into that you moved up? And it looks like you covered the canopy existing hole with a sticker?

You have to drill a new hole thru the frames and thru the plastic. Run a bolt from the back side out and then thread the canopy post to it.Gassers Rule, Nitros Drool, Electrics...uhhh...Joule?

Ok I see what you did now. I have a new canopy coming. Should be here later this week. The other one is somewhat messed up. Might be able to use it still. But the stock Canopy is ok, but in gray clouds it is a little hard for my old eyes to see it. I order a orange and yellow one like what's on my Trex 550. I never had a problem seeing it in the sky. Thanks again.

Here is a couple photos of my new canopy and I changed the location of the post on the muffler side. Move it up like Rototerrier showed me! I also upgraded to the micro heli canopy mounting post with the thumb screws. Went to are flying site yesterday and flew it. It is a lot easier to see now.

Thanks Papa Sal. It flies awesome also!! Saturday at the field I was showing some of the gasser airplane guys how nice it holds a inverted hover. They thought that was pretty cool.
