Cool, I'm just going to go that route. Thanks.

If my Plane is to tail heavy, will it slow roll rate or affect anything else.

Depending on how tail heavy, it can make the plane completely uncontrollable. In addition, if it is tail heavy, it will affect knife edge flight (whether the plane tracks straight or not). It will also affect the tendency of the plane to maintain neutral flight (no tendency to climb or descend) in upright and inverted flight.

There are lots of threads on telling how to adjust it, but the basic idea is that you first set it by getting the plane to balance the right distance from the leading edge of the wing. Then you fine tune it by looking at what happens when you try to fly inverted after trimming for neutral flight when upright. You want the plane to neither climb or descend when inverted at the same throttle level that you trimmed the plane to fly neutral when upright.

Speaking of CG stuff, I ran several packs thru the CY yesterday, after almost a month off. Talk about rusty. Anyway, I spent two sessions trying to get it trimmed well enough (being the rookie I am) to check the CG. Low and behold, it's a bit nose heavy. Didn't have anything with me to adjust the CG, so next weekend maybe. Looking forward to getting it dialed in.

The CY really is a joy to fly. I had way too much fun yesterday! Shhhhhh, Obama will have it declared illegal if they hear too much of that.

Do a lot of you have the CF landing gear that is almost 25% of the cost of the plane itself?

Is there a wire alternative?

Some customers do not like to run them, fortunately the LG is not needed to enjoy the model to its fullest flight potential. Personally I fly without the LG do to my flying loaction (backyard over grass).

If you are looking for a great alternative here is Get Real LG mod post. http://www.rcgroups.com/forums/showp...&postcount=288

I have Twisted Hobby planes with and without the landing gear. My Crack Yak has the LG. Personally, I like it, and I think it actually helps the plane be even more rugged. This despite the fact I fly in my back yard, and landing with it is mostly pointless. I do enjoy taking off from the deck with it.

It's all timing. Usually if I get the first rudder input in there quick enough the rest just kinda flows. I pick out a spot on the plane to look for as a key to make sure my fingers are in the right spot. That way if I get behind (or ahead even) I can adjust and keep the rollers going.

However... when I first started learning rollers I did use dual rates to help slow things down for me. I can't say whether that actually helped or hurt me to be honest. All I know is that my rollers started looking a LOT better once I went back to full rates.
do you have Real Flight Simulator? If so I'd LOVE to see a video of you executing rolling circles (with the remote window on screen so I can see stick movements).

I'm trying to nail this in Real Flight first and I've only been able to sustain rolling circles (1 out of 10 tries) using Ail and Elev (no rudder at all). I use the elevator to keep the alpha and to turn the plane. Although i dont exactly have full control over how tight my circles are...I can kind of adjust it but for 50% of it, i'm just along for the ride and every once in awhile I'll slam the elevator in or out to bring the plane back into the circle....

I'm using Phoenix, not RF. Sorry man...

If you learn to use both rudder and elevator I think you'll find that you have more control. This maneuever took me the longest to learn by FAR so don't get frustrated if it takes some time to figure out. Some people seem to pick up on it quickly though.

If you want to keep a high alpha rolling harrier then you're most likely going to have to pulse your throttle a little bit.

If you use rudder and elevator then they will both help you keep the plane in the air but then just think about the timing on your elevator for controlling how tight your circle is. If you hit elevator earlier (when the plane is close to KE position) then it will turn faster but you'll have to rely more on rudder for keeping the plane up. If you hit elevator later (coming out of KE position but still at a slight angle) then your turn will be slow BUT you'll also have the advantage of being able to use elevator to also keep the plane up.

I time my elevator based on the position of the canopy. If I want to roll straight then I try to have full elevator when the canopy is either straight up or straight down. If I want to turn then I hit my elevator a little before the canopy is straight up or straight down. My brain has just sort-of memorized what my left hand needs to be doing all time - it's just a cadence sort of thing mostly but the more I practice the more I'm able to adjust if necessary too.

So that's how I think about it but honestly - it just comes down to practice, practice, practice. The things I'm telling you were probably also told to me a billion and one times but they didn't really make much sense to me until I sort of just figured things out. It's just one of those things - once you know how to do it, it seems easy to talk someone through it but it doesn't make much sense to the person you're trying to help.

Hey guys,
I am having a little hard time centering my ail extension arm on the servo
.
I need about 12 clicks of trim to get it close to center and I know not to do that.

Are you guys using subtrim or lots of it to center the Aileron servo extension?


thanks

I spend a bit of time switching servo arms about and turning them around to find the ones that fit on at 90 with no subtrim before I fit the extension. You'd have thought all the arms would come out of the mold the same but they don't seem to. If I can't get them bang on I'll use a little subtrim but only if I have to.

I had to use a fair amount of sub-trim to get the rud and ele centered. Re-binding after setting things up resolved a flakey rudder sub-trim issue with the OrangeRX.
