A biplane takes some getting used to, it's not like jumping between the Edge and Extra. All the stuff that was automatic is now a little different. Once you get used to it I'm sure you will get stoked about it.

When I want to trim the balance I stop at the local tire store and pick up some mag wheel weights. They have super strong double side sticky tape and are calibrated in 1/4 ounce sections. You can stick them on the tail to make little adjustments in the balance.

I'd like to say that my DA 50 does pull the plane vertical nicly. So anyone thinking of using a DA 50 should be happy to hear that.

Tom, I'm sorry about hte confusion on the trim. I was wondering how it could be as far off as I thougt it was. When I figured it all out today I felt so much better.

RE: Wildhare Ultimate Build Thread
 

Now if I can only get some Wing bags for this thing. :)

RE: Wildhare Ultimate Build Thread
 

Hey ken almost got to fly mine today. Started raining after a descent engine on range test.

Taxing on the ground bounces the tail alot in grass, I think I will be nose heavy so I'm going to make sure to bring weights to the field with me.

I hope the weather will be better soon.

RE: Wildhare Ultimate Build Thread
 

Sounds like a call to Mike Bogh is in order. Very happy to see the trim issue is nicely settled. As you get to know the Ultimate a little better you're going to find out something interesting about the stalls that's fun to use in some maneuvers. It actually stalls twice due to the difference in incidence and sweep between the two wings. It's a subtle difference, but once you learn it some different maneuvers get to be real fun.

My "Pinky" Ultimate arrived today. Believe it or not UPS missed another opportunity and it arrived undamaged!

I'm an idiot, but who's Mike Bogh?

Thats great to hear. I know this is supposed to fly IMAC real well, but I'm dying to hear if anybody is doing any 3-d with these yet.

RE: Wildhare Ultimate Build Thread
 

I am dying to try 3D with a decent biplane. So far my experience is with two GP Christen Eagles, and two Dave Patrick Ultimates. Hands down you cant beat the Ultimate when it comes to Bipes. Yes they fly a lot different then say your typical monoplane, but then again there is things you can do with a Bipe that you cant do with a monoplane. Regarding my DP Ultimates I have hovered them, flat spinned, and have had perfect knife edges. I would imagine this one is the same. Silversufer is right; on all my bipes they are happiest when the CG is more or less at the rear cabane mount. A nose heavy ultimate will come in really fast. Double check both the wings incidence. After re-adjusting the CG on my Ultimate and adjusting the Incidence I got a decent landing. With all that drag you cant really just chop the throttle and glide it in. You have to fly it to the ground really.

Anyone hover one of these yet?

RE: Wildhare Ultimate Build Thread
 

Yes, I have hovered mine. Funny thing is I suck at hovering every other plane but it was easy with this. :D

Chaffing awarness!

My muffler is chaffing through the cowl. I the locations shown in the pictures. Be aware that using a DA 50 and Slimline muffler this will happen to you.

RE: Wildhare Ultimate Build Thread
 

My Edge did the same thing I took my time installing everything made sure the flat plate that comes with the muffler was put in with the longest side to the rear checked for clearance. One day I saw this little whole. Through vibration and or handling the plane things changed ive pached the whole and resecured the coweling. My local hardware store didnt have any rubber coated washers so i cut a very thin slice of fuel tubing and slid that over the screw after the flat washer this mashed down into the whole preventing any vibration issues from arising. So far so good. My Ultimate is still waiting for parts If i keep reading this thread ill be canibilizing the edge for parts. Thank you guy's for putting the time in to this your planes look awsome.

Bluemagic:

You better get going on that Ultimate, summer's almost over in Wisconsin.

RE: Wildhare Ultimate Build Thread
 

I had the same thing happen on an Edge 540 with a pitts muffler. I just grinded out a little hole for that part of the muffler not to mess up the cowl. If you want to see where it gets close (muffler to cowl) just check for any dark black spots. Pretty much common sense but its an easy way to tell where you might run into problems.

Very sharp looking plane though! What does it way with a DA 50?

RE: Wildhare Ultimate Build Thread
 

Tom Im afraid summer will be over long before the ultimate is ready to fly :~( there is allways powerball <:~)

RE: Wildhare Ultimate Build Thread
 

OK heres my story, wanted to test fly my ultimate today before heading to the Jumbo Jamboree. I had not completely set up the servos in the tail yet (Had these servos in my edge so I assumed they would be OK without any other programming). Checked CG for recommended specs, fired up the trusty ZDZ 50NG and let her rip.

1st flight was OK, needed minimal trim changes until I went inverted, boy did this baby drop. It was way nose heavy for my taste. Landed and started to add on the weight.

2nd flight was better with 2oz added in the tail but still not what i am use to. I tried some rolling maneuvers and a few up and down lines. Noticed a severe case of twisting when elevator was used, but elevator throw was OK for low rates. Ailerons though were incredibly effective. I had a 1:1 servo geometry and all aileron linkages and even at low rates they were way to sensitive. Landed and made a few more adjustments.

3rd flight I added even more weight and also put in a mix that would add some rudder at full throttle. The plane would pull to the left on the uplines and I was adding more rudder input than I should have been. The extra weight was doing the trick though and made the plane start to come alive. I then tried some knife edge maneuvers which in one direction had very little coupling but the other way was doing some crazy things. I think the elevators servos not working together was contributing to this so I noted it down mentally and keep flying.

4th flight was the most fun because even with the other issues to resolve I was still able to perform some descent 3D maneuvers.
Elevators had way less wing rock if any, especially compared to the WH Edge. and it was easy to flow from this right into high alpha harriers. I did'nt know if this bird would really 3d well but after only flying it a few flights I was impressed how stable it was performing.
It was a little breezy for torque rolls but I attempted them anyway, and once again for a plane that had not been tweaked out yet it did surprise me.

5th flight was the real test. I started to attract a big audience. Cameras and videos were rolling so I had to show off a little. Did a few more super stable elevator to harrier maneuvers and even tried some low level inverted ones. NICE...............
Some one shouted out flat spins so I punched the 50 and climbed straight up in 3D rates while rolling on the way up. When I reached max altitude I tried all kinds of spin maneuvers. I found that all were done best in high rates not 3D rates. when I finally returned to the deck I pulled out with authority to see if she would snap out............no way, she pulled out really tight with no sign of a snap coming.
I then went right into a rolling harrier and man did it roll. It actually felt like rolling a Tensor 4D foamy.
This plane likes to be rolled and I was more than happy to oblige.

Know I'm felling like I made a good choice with this bipe and ready to do some fine tuning to get out all she has to offer. Tonight I got the elev half's working perfectly linear to each other and took care of the engine thrust issue.

I had a friend catch some footage of a few of the flights. It has some of the 3D stuff thrown in there so hopefully tomorrow I will be able to edit it and find somewhere to host it.

RE: Wildhare Ultimate Build Thread
 

Anybody got a weight yet.

RE: Wildhare Ultimate Build Thread
 

Here's a picture of the Utlimate next to my 540.
FWIW, I have no idea what the weight is but my DA 50 yanks it vertically just fine. :)

RE: Wildhare Ultimate Build Thread
 

Here's my video of the first flights on the new Ultimate.

I didn't find my I-Link cable to upload it through the firewire port, had to use the usb so quality isn't that great but something is better than nothing

RE: Wildhare Ultimate Build Thread
 

Tom should add that vid to his site and show they can be setup to fly with no wing rock


Awesome flying there Mike looks like my flights if you take away the torque roll and add a lot more harrier rolls and walls to water falls
i do harrier rolls for every maneuver i do its crazy but i love the look of the high alpha rolls

RE: Wildhare Ultimate Build Thread
 

Thank's flatlandmike, I was flying it in 20mph winds and loving it. Very stable in 3D maneuvers which is what I was hoping for. But man those ailerons, supper effective.

RE: Wildhare Ultimate Build Thread
 

Alli know is Ken has to jump through some hoops to 1 up this vid or he can just put up the best he can for the time he has on the plane and ide love to see it [8D]

RE: Wildhare Ultimate Build Thread
 

I'd say that that vid is far better than what I can do. Good Job Mike. ;)I don't jump through hoops for anyone;):D

RE: Wildhare Ultimate Build Thread
 

Thanks ken, No contest here or at the field. I tell this to guys all the time, this hobby is all about having fun and it dosen't matter if it's with a 40% Extra, a 20lb warbird or even 10 oz foamy. Once your having fun you feel like a kid again and that's not only good for the mind but also the spirit as well.

RE: Wildhare Ultimate Build Thread
 

Mike:

That's a great video, can I use it on my web site?
