RE: Wildhare Ultimate Build Thread
 

Bull,

In response to your inquiry about carbon fiber rods and control systems, I've been using nothing BUT C/F rods for all my planes for the last several years due to their superior strength, resistance to deflection loads, and lighter weight. I haven't used them on anything over 30 pounds or so yet, but they have worked well for others at weights over 40 pounds. All I fly is giant sacle in one form or another, so I'd say the C/F rods work out pretty darn well.

Look at the pics I posted of my Ultimate and you should see a C/F rod or two in some of them.

For Tom Riddle:

I used the fuel tank that came in Tom's Hardware package. I can't remember right now if it was 20 or 24 oz. In one of the photos I posted, I had moved the tank forward so folks could see the plate I used to mount the receiver. Because it's pushed forward, it might look as if I had a smaller tank mounted in there.

Hope that clarifies. Enjoy your assembling. I will be re-configuring my setup from the pictures I posted earlier. I ordered a set of 1100 NiMH batteries from NoBS batteries to replace the hobbico 1600's in the pictures. It'll take about 2 days to do all the formatting charges they recommend, and then I'll need to see where to place them for balance. Hopefully, it doesn't require major mods in my setup.

Gary,

Thank you for the quick reply. I recall from some other threads that a 16 oz tank was usually sufficient for 10 - 15 minute flight on a 50cc (and would leave a suitable reserve without hauling extra fuel around).

I'm using NoBS NiMHs as well - great product. Currently measuring 3x to cut (the cowl) 1x. My BME 50 requires some standoffs so I'm triple checking the distance to go with the Hanger9 mounts that I am using.

Still searching for a "wild hare" pilot, though...at least Easter is coming so I have plenty of applicants!! :)

RE: Wildhare Ultimate Build Thread
 

Ken,

Thank you for doing such a great job with this thread - I especially appreciate the detailed cowl cut-out pix.

Does anyone know if the DA50 cylinder head and pitts muffler combo has about the same size/shape as a BME 50 cylinder head/pitts combination (as regards cutting the WH Ultimate Cowl)?

Any pix of a BME cowl cut-out would be very much appreciated.

Also, any considerations for using standoffs with a BME? I'm thinking about mocking them up with wood dowls (to get the measurements & spacing and then asking Roger Forgues to make a custom set for me. Kind of a 'Pimp my ride" approach... [8D]

You are very welcome, I sure wish I could help you with your BME dilema but I am afraid I can't. Hopfully some one will chime in for you.

RE: Wildhare Ultimate Build Thread
 

Ken,

Thank you very much for the quick reply. No worries - you have provided a wealth of assistance already and I just wanted to say thank you.

I found measurements for the DA50 (including dimensioned drawings!) on the DA website - I think I can work it out...now, where is that tape measure....:)

RE: Wildhare Ultimate Build Thread
 

Hi Tom,

I'm disappointed with my attempts to make the cowl cut-out look decent (apparently my dremel thought it was in charge). Its not a total loss or anything, but I'd like to try it again - Do you sell replacement cowls (or is there a 3d party vendor that does)?

Yes we have spares for the Ultimate in stock. Please call me at 817-430-0107 to order.

For those who might be considering a BME 50 for their ultimate, the Hanger 9 1.20 - 1.80 aluminum mount (recommended by Keith at BME Engines) works very well with the SWB Manufacturing 1"-1-7/16" Motor Stand Off kit.

RE: Wildhare Ultimate Build Thread
 

I bought a World Models Ultimate about 8 months ago. Shortly afterwards, however, I got very busy at work and had to put my R/C stuff on hold for a bit. So... the plane sat in the box collecting dust. Recently, I decided to get serious about building my first gasser/ultimate bipe. However, I've been reluctant to start building the World Models plane because I really wanted a Wild Hare Ultimate all along. (I only purchased the World Models bipe because it was a bit cheaper.) Anyway, I finally decided that saving a few bucks isn't the priority and that I should buy the plane I want. Unfortunately, today I found out that they are out of stock of the yellow scheme and will be for 3-4 months! Doh!!

Tom, please let us know when you get more planes in... I can wait a bit longer I suppose.

RE: Wildhare Ultimate Build Thread
 

In the mean time you can get the WM plane in the air to practice with until your color comes in. I had a couple of them and they are pretty fun, but 3D is out of the question. Nowhere near as capable as the Wild Hare, but a good way to get into the swing of things. Did WM ever do away with that flat abortion they called a cabane strut?

BTW, there's an Ultimate for sale here in the W/H forum. Don't know what color but you might want to make contact to find out.

RE: Wildhare Ultimate Build Thread
 

For those about to, or currently setting set up an Ultimate, an addendum to the C/G notes in the instructions should be added not to exceed 6-7/8" aft of the leading edge of the top wing measured from the "point". Anything aft of that point will be exceeding the maximum aft C/G limit for the plane, and can leave you with a plane dangerously quick and loose on the controls.

An excellent location for superb performance will be in the 6-1/2" to 6-3/4" range.

Pat

RE: Wildhare Ultimate Build Thread
 

Well since I was running the tape measure for Pat I can agree not to exceed 6-7/8th.
By the way Pat where did it end up at??? I still think you need at least 1/2 forward of where you are.

RE: Wildhare Ultimate Build Thread
 

The name of the game is I like it like that!

RE: Wildhare Ultimate Build Thread
 

You must be enjoying your flight;)

RE: Wildhare Ultimate Build Thread
 

35,000 feet over Greenland, First Class in a 747, perusing my favorite forum on RCU while talking R/C planes. Who wouldn't be enjoying the flight??!![8D] All that will change soon enough:eek:

RE: Wildhare Ultimate Build Thread
 

I thought the WM Ultimates were pretty good for 3D. In any case, I told my wife that I'd sell the WM plane if I got another one. I decided to purchase the WH Yak-54 rather than wait for the yellow ultimate. (I'll buy the ultimate another time.)

RE: Wildhare Ultimate Build Thread
 

It's been a while I have had mine sitting on the wall for 1 1/2 yrs... Just never got to finishing it... How has the plane held up over time with you all... My interest turned to Warbirds and my time has been limited... I am so close to finishing... I have a 1/4 scale Balsa DR-1 I am finishing and when I am done will get back to the Wildhare Ultimate... Should be done this week with the Dr-1

RE: Wildhare Ultimate Build Thread
 

Question for you guys out there that have built the Ultimate.
On the wing struts, are there blind nuts that need to be installed in the tabs that go in the wings or are the blind nuts that need to be installed in the struts themselves?
I really got hung up on this just looking at the instructions.

I understand that the tabs have to be drilled out once the struts are set and the incidence for the top wing is set, but I just didn't see what is going to hold the bolt that you run through the struts and tabs together without adding a blind nut.


Sorry for such a stupid question but I am still new to this game.


Thanks

RE: Wildhare Ultimate Build Thread
 

There is a blind nut already installed in the strut, it's covered over. They usually fall out when the covering is opened up, but it's easy to reinstall.

TF

RE: Wildhare Ultimate Build Thread
 

Thanks for the info Tom! :D

RE: Wildhare Ultimate Build Thread
 

Okay, I opened the hole up on both sides of the struts. One hole in the strut is routed out and the other is not. There are not any blind nuts on either side of the strut. However there are eight blind nuts in a bag that is with the struts.
Do the blind nuts install in the routed out side or the other. I figure they go in the routed out side but just trying to make sure.


Thanks again

RE: Wildhare Ultimate Build Thread
 

I have to say this. I have this Wild Hare Ultimate 10-300. It had come to what I thought was a complete end to its life Lots of little pieces. Well a friend of mine Purchased it from me as is. I thought he was crazy But he put Humpty Dumpty back together. Then he sold it back to me. I had allready replaced it with another WH Ultimate And yes that one has met terra firma with some hast and is in need of TLC. So I got another chance to fly Ultimate #1 and youd never think this to be true but even after being all glued back together IT's still IMHO The very best 3-D plane I have.

P.S. Thank you Tom for getting the next Wild Hare out to me in such a timely manor. You got even Newegg beat in the shipping race.

RE: Wildhare Ultimate Build Thread
 

Geeze, what a mess.

RE: Wildhare Ultimate Build Thread
 

Hey guys, this is a great thread. I ordered mine last week and I am trying to patiently wait for its arrive. I am starting to gather together a build folder with all your tips and tricks. When I get it started I will post a build thread of my own.

Thanks for all the great info.
