Use the same type spinners for bigger props. The spinners are prop specific so be sure which prop you want to use.

They're cheap.

I'll trim out the Dubro till I see what prop size I want. Or I'll use a spinner nut.

How are you fueling your Edge? I'm going to use a Fuel Dot.

It's supposed to rain for the next three days so I'll have plenty of time to complete the plane for Saturday.

I got two sets of pictures on the previous post because they didn't show up on the review so I downloaded them twice???

Thanks to all on this thread. The directions are somewhat confusing. This would be a tough build if it were your first ARF.

I think the APC 15x6 is the best choice for you if you have a Saito 100. 16x6 for the 125. Both fit in the TruTurn 2.5" 120-slot spinner. The screw holding the spinner has to be cut to length most of the times anyway. CentralHobbies sells alternative adapters. They can help you out, but simply use the included spinner for now until you're sure what prop to use.

I have a completely different fuel setup with header tank and Perry pump. If you use muffler pressure have one line from the muffler go to the top of the tank, one line with clunk from the tank to a filter to the carb and a third line with small clunk for fueling. In stead of the 3rd line you can also use a T-joint in the fuel line going to the carb as close as possible to the tank. Have the carb completely closed when fueling/emptying the tank!

Also on one of the pictures with the CF gear you see a little wooden extension for the cowling. My Saito is mounted a little over 1/4" more forward which helped balancing the plane also. With this setup and a 4-cell AA RX pack on the stock location the plane will perfectly balance. I use a 5 cell and had to move the battery a few inches to the back.

Glue a piece of 1/32 ply with epocy inside the cowling where you mount the fuel dot.

Who's aluminum spinner did you use??? It looks great!!! I see a Saito 8mm adapter kit on your site.

I'm trying to use a Dubro but there's going to be a lot of trimming with my 16x6 APC prop.

We are getting the advance showers from the storm so I worked on the Edge Today. Vine, your log has been invaluable. I had to shorten all the graphite rods to your dimensions. Everything seems fine.

Did you have a little wiggle in your rudder??? I guess a surface that large with the horn in the lower corner is bound to have a little wiggle?

I'll install the Saito 125 tomorrow and cut the cowl. I already set the throws ( wow a lot of Rudder throw) and balance the plane. By the time the storm passes Saturday she will be readt to fly.

I Dremeled the Dubro spinner and it fits the 16x6 and 16x4W fine.

Again, thanks for all your help.

Tom

Yes, a little. While the supplied metal clevis fits tightly in the surface's white nylon control arm, they are just a tiny bit smaller than the hole found on Futaba servo arms (and also the Dubro replacement set I ended up using in a couple of places). I agree that the larger size of the surface exaggerates the condition.

I guess that little play is nothing in relation to the size of the surface. Plus, all my planes have a little surface movement ... if they were super tight I think they would likely bind and/or require more servo power than actually needed.

I haven't noticed any fluttering in flight.

Sounds good to me.

I used the larger Dubro servo arms on the ailerons and rudder to get the required throws. I have the rudder clevis in the middle hole on the horn and had to cut away a little off the bottom to clear the rudder.

I'm going to wick some CA into the wood around the rudder horn to strengthen that area.

It's raining today so I'll be finished by tonight.

You can also use standard 1" servo arms and eg Robart ball link control horns or dubro ball links with 4x40 rods on the standard plastic horns.

Use 1/2" on the ailerons
3/4" on the elevator halfs
1" on the rudder
http://www.robart.com/Horns.aspx
Super Ball Link Control Horns (Aluminum Ball)
so one Dubro ball link on one end and this horn on the other.

http://www.hobbypeople.net/gallery/868471.asp
you can also use 2 of these on one rod with the standard plastic horns

they last forever with zero play

And if you wanna do it even nicer get a bag of 4x40 rods, cut them with 1" threaded and 1" non threaded. clean and roughen the non-threaded end and glue it a carbon rod. Very light and strong.

PS
You need the Dubro 2-56 ball links with 4-40 thread. These are smaller and lighter and strong enough for this plane.

How far back did you guys cut the bottom of your cowl????

I finished the Edge 540 today. T balance it laterally it took five x 5" strips of 3/4" lead tape on the left wing tip.

The first try at balancing required over 2 ounces of tail weight. I moved the battery back where I had the receiver and mounted the receiver beside it. It then required only 25 GM on the tail to balance at 100 mm.

I put on some decals. I don't like a lot of big letters so I stuck with the small stickers.

Pictures attached.

She's ready to fly on Saturday.

Tom

Tom,

Looking good.

So, you are one of those speed builders :-) I worked on mine off and on, and got it built in 2 months, but even if I hurried (and did less flying with my other planes), I'm sure it still would have taken me at least a month.

My muffler cut out is like yours except I didn't go quite as far back. I stopped about 1/4" past the large bell of the muffler (so all the exhaust will surely go outside the cowl). The only drawback is that I have to remove the muffler to get the cowl all the way off... Do you (cut the way yours is)?
I tried a Dubro diverter but it blew right off the first time I went full throttle (on the test stand, running-in the engine).

I didn't balance mine laterally ( I probably should). I balanced mine right side up and it came out tail heavy. Since it's not really a low-wing I wasn't sure which way. The manual doesn't say but the picture they show is right-side-up.

How did you and Martin both end up with that blue motor mount? Is that what they are shipping now? Mine was biege.

I started on my wheel pants installation (following your directions). It will be the same as your except I have Dubro axles.

I put 3 more flights on my Edge today.

She flies pretty good, although every once-in-a-while it snaps or something else a little weird or unexpected (rolls out?) coming out of a loop. If I throttle back on the down-side of the loop, it's usually fine.

Yes, I want to fly them ASAP. I have been flying for 17 months and have 925 flights.

My muffler cut out is like yours except I didn't go quite as far back. I stopped about 1/4" past the large bell of the muffler (so all the exhaust will surely go outside the cowl). The only drawback is that I have to remove the muffler to get the cowl all the way off... Do you (cut the way yours is)?

I enlarged the cutout for ventilation. I read that is should be at least twice the intake. Also it allows me to take the cowl on and off with the muffler on as well as deflect the muffler further down.

I tried a Dubro diverter but it blew right off the first time I went full throttle (on the test stand, running-in the engine).

I didn't balance mine laterally ( I probably should). I balanced mine right side up and it came out tail heavy. Since it's not really a low-wing I wasn't sure which way. The manual doesn't say but the picture they show is right-side-up.

With a mid-wing I guess you can balance it both ways???

How did you and Martin both end up with that blue motor mount? Is that what they are shipping now? Mine was biege.

That's what they shipped??? Seems very sturdy.

I started on my wheel pants installation (following your directions). It will be the same as your except I have Dubro axles.

I put 3 more flights on my Edge today.

Ernesto is gone. We got 11" of rain and a lot of wind. Tree limbs and leaves everywhere. The weather today is perfect. 80* and light wind for my maiden flight. I'll let you know how it goes.

She flies pretty good, although every once-in-a-while it snaps or something else a little weird or unexpected (rolls out?) coming out of a loop. If I throttle back on the down-side of the loop, it's usually fine.
