Don't know what type of flying you like but you might look into a little better servo at least for the rudder. The 5645 is rated at 168 oz/in and a speed of .18. Might be a little on the light side.

On my 50 cc I run a 7955. It's 333 oz/in. I'm trying a couple A6030 servos on the elevators of my 50cc Extra and really like them. At 278 oz/in they might be a great servo for you to think about.

On your rudder servo arm, don't forget that if you're running pull pull, you need a servo arm that is as wide as the rudder horn total width. 2" sounds a little short to me.

Just my thought. Good luck with your new build!

As far as the servo,I had them already from a previous plane and thought to use them as a start to keep the budget down. The 2"servo arm is for the elevator not the rudder. I am using the included rudder arm which is big enough. Thanks for the thought

Duh........2 x 2" arms for elevator. I should have stayed awake in reading class.

<span style="color: #0000ff"><span style="font-size: small">No problem
Why do you think hitec 6545mg is not sifficient? It is recommened for this size plane. I had them installed in a giantKatana 85" WS that weighs 18 poundsand had no issues whatso ever.
Can you explain?

Get ready to redo the tail wheel, the spring arrangement sucks.

I removed the spring, drilled a hole straight up in to the bottom of the rudder and glued a ball link end in. Then run music wire from the top of the tail wheel where the spring was attached and run it through the hole in the ball end with about 3/4" sticking out. You still get shock isolation but ground steering is much MUCH improved.

The rudder pull/pull arm comes with the kit, and using it is the only way to get decent geometry.

The graphics are miserable, send me a PM if you want help there.

Go to Ace Hardware and get 10 sealing washers. Use 4 of them on the tail where the stabs bolt on, 4 of them on the cowl, and 2 on the canopy.

Ditch the 6v pack and run a 4 cell on the ignition.

The airplane is an absolute blast, you're going to love it.

the 5645 is an Ok servo that will work, but the speed is slow, the centering is so so, and the gear train will have slop in it after the first few flights. Go with the 7955' on the rudder, the aileron and elevator the same, or 7985's. Loose the 2000 NMH especially if its one of those double A packs. Much internal resistance equals voltage drop. If your serious about giant scale get rid of all the sig kadet, senior falcon equiptment. Redundant A123's, and better servos

Thanks for the  pictures. It looks much stronger. Where did you get that long ball link?

I got the plane. Everything looks good except that there was no manual and no rod and plastic washer for the rudder hinges. Is that included? I saw it on the online manual. Any ideas?

The manual is online, its a general 50cc manual for download only.

If its the rudder hinge rod you're looking for check the stab tube.

Mine was either in the wing tube or stab tube. If not then give your dealer or Chief Aircraft a call.

the 5645 will work in a 50cc plane....great for starting out.... i have a 50cc yak that i had 7955's in it all the way and it was awesome.... i swapped them out for 5645s with the exception of the rudder, and i could tell the difference in doing more precision flying like hesitation point rolls, and KE to KE snaps.... im not a hardcore 3d pilot so i couldnt really tell much difference for 3d type aerobatics

Thanks for the opinion. I will use the 5645s I have for now. I agree with you they are enough for this size plane. One thing tho. Why do I ahve to use a bigger servo on the rudder? why cant I use the 5645? and is it ok to use the 5645 for now?

I am done with the plane except the rudder cos I am waiting on the hingerod to come from chief aircraft. I will post pictures soon.

If you dig knife edge (and this plane really excells at it) then you're going to want a good servo on the rudder.

All depends on your flying style.

Got it, thank you. i also wanted to ask, the elevator is shaking while the engine is one so i checked it and found that tgere is a slack in the servo for about one millimeter back and forth when it is not running. Is that normal? Never seen that before.

Not good, not unsual for those servos, its why I run TG's

Hit servo city and get a gear set and get rid of the slop.

Check out the graphix make over on mine

The plane looks very nice!! This is the same color schemeI have.I called hitec and spoke with a customer service rep about the slop and he said that it is normal in this type ofservo and since it is still a new servo soI will just fly it and see what happens butI am planning to replace all with the 7955s. I will post some pictures shortly.

Hi,

I can't tell if the surfaces are centered in some of those pictures but when the elevators are centered the arm should be straight down, when the aileron is centered the arm should be parallel to the hinge line.

Yes they are centered but maybe they just moved while I was moving the plane around

This is what I did for the tail wheel. I couldn't do the other idea with the wire. What do you think?
