Ultimate Biplane
 

The one thing some of you fail to realize is that you are comparing apples and oranges when you are talking about the DP vs Goldberg argument. The DP is either a .40 size or a 1.20. It does not good to compare the 1.20 DP to the .60/.90 size Goldberg. The fact is there is no plane in the Goldberg size range that I have found other than the WM, and nothing against WM, but there plane is not the same. If I wanted a larger plane I would not hesitate to get the DP 1.20. But the fact is, the three things that put the CG Ultimate if first place for me are Quality, Looks and size (not to big, not to small, just right).

anyone know of someone powering a DP with a gas engine?

got a friend who bought a converted CG ultimate to 60in witha gasser. was nose heavy, flew heavy to landing but was still a typical ultimate in handling all around...

Ultimate Biplane
 

Well guys, after some thought, I will just have to settle for the DP 1.20 ultimate. ;-) Now, chosing a powerplant for it. What do you guys think about these choices:

1) OS1.60FX two stroke, 3.7 hp.
2) OS160FS twin four stroke, 2 hp but should be able to swing a bigger prop or pitch than the 160FX.
3) YS140DZ, no idea on hp. Actually, no idea about the engine or how good the YS line-up is.

I am partial to OS, only because I have had only OS and never had any problems and they start every time right out of the box. Thanks again.

Go with YS power! BUT--don't waste your money on a DZ! The new YS 140 Sport is just over $400 at central hobbies new. I bought one and put it in my DP Ultimate and it is a great performer! I use a Pro Zinger 18x6 on Coolpower 30% and get high 8000's static. My plane uses 4 Hitec 5475HB digitals on the ailerons (MORE than enough torque) and JR 8411's on the elevator/rudder. My engine is mounted inverted with a remote glow plug and a Robart Ultra Fueler for the pressurized fuel system. The plane is a FABULOUS performer and has MORE than enough power for the weight of the plane. I started out with an open exhaust and have since switched to the Performance Specialties muffler with the rotatable exhaust positioning. It's a fabulous combination. A 20 oz fuel tank and an 1800 mAh NiCad give nice long flights with no fuss. I haven't had a single dead stick with the engine (the norm with YS) and the engine pulls the plane through easy knife edge loops on a full fuel tank. 3D type flying is easy with the throws cranked up, but I usually fly more tame flights with the plane because it is just so darn pretty in the air. The bottom line is you'll love the plane no matter what you have in it, but I definitely wouldn't waste the $$ for the DZ when you can get great performance for a couple of hundred dollars less.
Good Luck!

Man, Am I depressed!
 

I lost my CG Ultimate Sunday. Went straight in, total loss. I'm so depressed right now I'm ready to chuck the whole thing (flying).

I have about 20-30 flights on mine. No problems at all. I've been getting into IMAC and some 3D stuff. No problems. Never saw any bad tendencies in any flight mode. Well last week one day I was out a ways and turning to come back and almost lost her. she was going straight at the ground and not responding. I saved it about 30 feet from the ground. Well not so lucky this time. I was flying straight away from me, doing some trim checking and I think I may have let her get to far out. Don't know. Was turning around at about 1/2 trottle she just quit flying and went straight in, would not respond to an elevator command at all. Only thing I know is that I was on low rates and pretty far out. I guess one of a few things happened. I got to slow in the turn without enough power and she stalled. Then I didn't have enough elevator on low rates to pull her out. Or I just got to far away and had an interupted signal. I just loved this plane. Right now I'm about ready to just quit! I hadn't flown anything else I owned since getting the Ultimate. I've crashed a lot planes, but this one hurt.

Steve - Did the pilot survive? He's survived through about 3 airplanes and 8 or so years of flying before taking over the stick on that Ultimate. Sorry to hear about the plane. Hope you get a replacement soon and get back on the horse!

If you guys are looking for an CG Ultimate Bipe, There is a place in Minneapolis MN. that has them on hand.

Do a search for "Hobby Warehouse". His number is listed in some postings.

And he is selling them at a really desent price, 299.99.

Also the cheapest place to buy Saito motors.

Oh, hey Ron. The only thing that survived was the top wing, pilot and spinner. Go figure. The muffler bracket cracked at the head so the engine may be a loss also. She was not spinning or twisting. Just going straight down and hit on the edge of a grain field about 150 yards out. I am really perplexed and now convinced that little near mis last week is related. In both cases I was in a high bank turn to the left. I'm no expert, but I'm not that bad either. Anyway, here is a pic of your beautiful plane.

Great vision probably hurt
 

As a Naval Aviator (A4's right?) you've probably got great vision. If so, you most likely did fly out of range. Or far enough away that there was a signal interruption. You and Chuck Yeager need to learn that RC stuff is made for the average folk ;)

Really sorry to hear about the Ultimate. :( You have to get another one quick! :)


Get a 60 size Ultra stick (or use an old plane). Throw all your gear into that and test it out. Let's stay away from those "real long range checks". :p

It's probably fine. Then get a new CG Ultimate and put it back in that. Doing this will bring back that comfort level so you won't over-think things.

The bright side is now you don't have to mess with the throttle linkage on that old worn out Ultimate you were Flying.

Military men aren't quitters! :mad: We come back stronger and better prepared. Let's here about that new ultimate you're going to build! :cool:

Scott

Yeah, actually I was not all that depressed. More like pissed off. I had just fixed the throttle. Luckily I had not gone to the trouble of moving the elevator servos yet, thank god. I almost did it the night before.

I talked to YS today and they say their distributors should have the new YS110's by the end of June. A Hobby Warehouse Ultimate and the 110. Hmmmm.


PS: Scott, how did you know I flew A-4's?

Previous thread
 

I was trying to explain about "fanning" the elevator of my ultimate on approach. You mentioned that you flew A4's and couldn't figure out what the heck I was doing. :D

At only 150 yards it probably wasn't a distance thing that caused the crash. On certain frequencies at certain places you can get frequency interference. I've had it happen on a perfectly good system, and been able to repeat it. That may have been what happened to you. You probably want to check that out before committing this same gear to a good plane.

If you've got an old plank you can throw all your gear in, it will really increase your confidence when you put this stuff in a new plane.

As for the engine, you would be amazed at what you can do with JB weld. I once had to make a complete thermostat housing for a boat engine to get home!
Worked great! I just had to spend an extra weekend on the island (tough life ;) )

Glad to hear you're gonna get another Ultimate. I can't imagine not having one in the fleet.

Best of luck,

Scott

Sorry to hear of your crash.. I miss mine, but I bought another kit plus glass pants and cowel, so this winter I'll be framing it up. I had an old, tired SuperTiger 90 in it with an old Jtec manafold, and it flew very nicely.. That same engine came out of a TopFlight P-47 that went straight in cuz some jerk was testing his engine in the pits @ a funfly with no freq pin. The plane was nothing but splinters, and the engine's carb broke right off.. I jb-welded that engine back together not expecting it to run, but it ran just like it did before with no problems. No 3d, but it'd hover on the prop, and would keep going vertical wide open.. slowly, but it'd keep chugging. Loved that airplane. I have an OS 1.20 surpass pumped laying around calling out for the new ultimate once it's built :) It was the best behaved planes I've ever had, right next to my Goldberg Extra 300.

Actually I had not thought about JB weld. The only thing that broke was one side of the exhaust manifold mount were the screw goes in. I may be able easily JB weld it.

As to the Goldberg Ultimate. One good thing that has happened, if you can call it that, is that I have gotten a real good look at how this plane was built. I got to say I am amazed at the overall quality of the construction throughout the plane. It's very solid and the wood quality is high. Goldberg has done several nice things like installing an antenna rod, pre-installing the tail mounting nuts, cutting holes for the cabanes, etc, etc. I got to admit that I thought the Klett tailwheel looked a little gimicky at first. but it is one great tailwheel. While I am not a fan of Y elevator rods; but at least goldberg included a DB fiberglass rod instead of the wood sticks most manufacturers use; and a very accurate template for assemblying the rod.

None of the servo mounts, engine mounts, wing mounts broke in the crash. Everything else did, but not the mounts.

Ultimate Biplane
 

Man; I hate to see that. Good news about the quality construction, though.

A question, though; did you put those yellow stripes on the top of the wings, or did the kit come with them?

I ask because all the photos I've seen of this ARF do not show the upper wing surface stripes. They do make a difference in the model's visibility, so I need to know whether to plan on getting some Dark Yellow U-Cote to do them with.

No bites on the helicopter I need to sell before I can get one of these... bummer.

Steve

Ultimate Biplane
 

I added the strips 4" with 1/4" side trim on the top and two 4" front to back on the bottom of each wing tip. Boy did it make this plane look good and easy to see orientation no matter what you were doing.

Ultimate Biplane
 

Cool; thanks.

Now, to get this darn helo sold...

Ultimate Biplane
 

Steve -- Here's one to check out. Would make a nice replacement for that Ultimate!

Yes, I saw that. If I did not already have a YS1.20 and all the servos I need I would be tempted. I have been thinking that getting the larger DP would be nice. but I just do not want to have to put fuel in one of those gas guzzling larger engines.

If the Goldberg flies great on a 1.20 size engine I don't see how the larger DP could fly well on anything less than a 1.40/1.50 size engine. I'm going to try and talk to DP about this later today.

I have looked everywhere for a Goldberg. All the shops are out of them. We were talking the other day and are somewhat concerned that the next runs of Goldberg Ultimates will not be of the same quality as before now that they have been purchased by Lanier. I have had a couple of Laniers planes. They are OK, but not up to the Goldberg standard at all. Hope they do not change manufacturers on us. That would be a shame.

Ultimate Biplane
 

<<...not up to the Goldberg standard...>>

This has been a nagging worry in the back of my mind. While they have improved by leaps and bounds since I last had one in the 80s, Lanier ARFs are still nowhere close to same league as what these Goldbergs are; IOW the best.

I say that after assembling nearly two dozen ARFs from different manufacturers in the past sixteen years, and looking at many more. The two Goldberg ARFs I saw were simply of the highest quality overall; World Models offerings are close, but the cheap-jack Pacific Rim hardware is a liability there. The only other company that, IMO, equals those Goldbergs is SIG ARFs. I have the LT-40 and Somethin' Extra, both of which are excellent. And, more importantly, I used almost everything in the box. Usually, the first thing I do with an ARF is gather up all the hardware, pushrods, etc., and toss it.

I agree, Steve; this could be a problem. We won't really know until someone like yourself who has seen the original can look at the new offering.

I'll be waiting for THAT report with bated breath...<G>

Well I'm no longer a "Goldberg man". They can go to dog do-do if they want. I just ordered my blue 1.20DP today. According to DP some of the guys putting big engines on the 1.20 have egos to match (not their words exactly). Sandy says the big Ultimate will fly beautifully for what I want with the YS1.20 and the Hitec mini digitals I want to put on the wings. So now I'm a "DP man". I can't wait.

Ultimate Biplane
 

The DP flys just fine on a YS120. It will hover, do some 3D depending on throws. IMHO any plane that will hover is certainly adequately powered unless wild 3D is your taste. A 140 is only needed for ballistic vertical performance. A 120 on a Goldberg is a little much, although I know many people use them quite successfully. Remember that the Goldberg is a 9ish pound plane, give or take. The DP should come in around 11ish. The Goldberg was designed as a 60 size two stroke plane, the DP as a 120. Patrick designed them both.

Ultimate Biplane
 

So I take it they still have the 120 size blue ones in stock?

Ultimate Biplane
 

I think she said they were down to last 3 or 4 and I just got one of them.

Ultimate Biplane
 

Well, hell, Splais; you were gonna be my test mule for the "new" Goldberg/Lanier Ultimate... :-(

The DP Ultimate is just not an option for me; it won't fit in my ride.
