I think I may have set the record for the longest time to get an ARF in the air! I started working on my WH 28% Edge in November and if all goes well it will make its maiden flight this coming weekend (lots of distractions this spring ). I have a few radio set-up questions and also some balancing questions.
My throws are set at the following angles Aileron low = +- 17 deg hi= +- 25 deg Elevator low = +- 15 deg hi= +- 35 deg Rudder low = +- 30 deg hi= +- 45 deg Do these seem ok for an experienced sport flyer or should I adjust these throws?
1. I was wondering what you guys would recommend for exponential for the first flight? I was told once that roughly 30% on the low rates and 70-80% on High rates should be a good start point, what do you think? 2. The manual says to balance between 4 ½ ” and 5” but it seems that most folks here start at around 5 ¼”. Would starting at 5” be a better start point? 3. Where do you guys add weigh for lateral balancing (wing tip or in fuse.)?
Thanks for the advice.

15 degrees on the elevators might make the plane snap when you don't want it to. I had mine at 16 degrees and it would snap out on the bottom of a regular loop. I bumped it back to 12 and it hasn't snapped yet. I'd stick to 12 degrees on low rates.

Thanks for the replies guys. What are you using for lateral weight and how would you attach it to the wing? Any more thoughts on the throws and radio set up?

My crude method..
I hang the plane inverted by a string to the center of the firewall(not the motor shaft) and the tailwheel. I then place 16 penny nails on the light side until it balences usually only takes 1 to 3 nails. Then I peal the covering back at the wingtip, drill a very shallow hole the size of the head of the nail, then after dipping the nales in goralla blue I drive them in. Last the covering is carefully reapplied.

As it turned out I didn't need to add any weight to balance laterally or fore-aft. I am using 2 1950MAH NiMhbatteries for the receiver and by putting them in the center and right side with the receiver on the left it's just about perfect. The left wing hangs about 1/2inch lower at the tip. Is that close enough or would you still try to get it exact? The fore-aft is balanced at 4 7/8", so I think that should be OK for the first time out. I'm going to try to do the maiden flight on Saturday if all goes well. First flight with a gasser, Wish me luck !

You'll want to do the lateral balance in the air "dynamically" anyway. Don't worry too much about that now, you got it close, so fly it and have some fun...then worry about the fine tuning in a little while when you get the bug to tinker.

Here is a couple photos of the inside. It was to dark when I finished strapping things down to get any good photos of the exterior so I'll take those tomorrow or Friday and post a few. I found if I stacked the 2 battery packs I could get the lateral balance right on but once I put padding between them they seemed to flop around to much, even when the straps were tight. So I left them side by side for now. The final weight came in at 18# on the dot. Thats with all the stock hardware, wing tube, landing gear, (3) 1950MA NiMh batteries a DA50 with a slimline muffler, aluminum spinner, and a 22x8 Menz prop. I'll start shaving weight after I get some flights on her. maybe some carbon fiber here or there and I may switch to Li Ion.

I have a hunch you'll be having so much fun flying her the way she is you won't want to put her back in the hanger for a Jenny Craig overhaul She flies light even at 20 pounds so you're going to have a great flying plane.

WW2ACE,
In your 3rd picture you show the connectors. You have a nice setup there, BUT these connector “supports” are not good. They can slip down on the wire and then they are worthless. May they are good for some temporary purposes but not for permanent safe connections.
I use always dental floss, this is strong and will never give away. Some guys use shrink tubing, well this takes awhile to disconnect the wires later. There is the dental floss convenient again.
Just my opinion, I would not have a good feeling when the bird is in the air with these “supports” on the connectors.

I know I’m a pain in the – you know where. But, one more. In the second picture I don’t see any fuel filter. I would recommend placing a fuel filter between the tank and the carburetor.

The best thing to use to secure your servo leads together is buy some 3/8 shrink wrap. just cut it long enough to go over both of the connectors. i think this is the best way but thats just me.

Been using the shrink tubing method for years. Agreed it can be a bit irritating to remove but it will never fall off or let a connector come apart. There are too many methods to secure connectors to count and just about all of them work pretty well.
I've got a hunch that WWII Ace has all the right filters in all the right places. If I took a similar pic of any of my planes you would not see a filter until you either looked inside the tank or got a lot closer to the engine. Not to mention the one in the fuel can.

I also use the heat shrink tube method. Cheap insurance. Many other cheap methods that are easy also: 3M blue painters tape, mini zip ties, Parson's clips, slimeline's clips...ect.
