I've built and flown the Nitro Ultimate 46 with a 52 Magnum on it. Way more engine than the plane needed. A quick backoff of throttle was needed.

Mine was missing most of the screws needed to complete the build and had a bunch of extra screws that didn't go anywhere. The battery is under the pilot seat. I added 1 3/4 ounces of lead to the tail and 3/4 ounce to the right wingtip. I have a World Models Ultimate 46 and used the template from it for the incidence. The worst part was the covering. It took an hour of ironing to get it on tight. The next worst part was the instructions. They are just a partial copy of the World Models instructions.

Guys that have flown the Nitro Planes should do some reviews in the User Reviews. Here's mine!

Heres My Plane.

Nitroplanes e-mailed me back saying that they would get me the missing alignment jigs.

I did not have any problems with the finish as per the previous poster, and a bit of final smoothing is standard for most most ARF's... I don't consider this a problem.

The manual is indeed a mess, but of course you can download the WM manual.

I've also ordered a WM plane as a backup so I can compare the two.

If you are aware of it's minor shortcomings (which ARF doesn't have ANY????) then this is a fairly nice plane.

If you are doing an electric conversion the lack of the cowl cutouts and firewall holes is a BIG plus!

I agree. I've only built one kit since 1983 due to my problems being around glues (mainly CA), almost all the arfs I've built have had some sort of covering problem. This one was just exceptionally bad on the fuselage. It could have been caused by humidity, heat or cold encountered in shipping from wherever it came from. The quality control in parts shipment was one of the worst I'd seen also. It was missing a bunch of screws and had a bunch that didn't fit anything anywhere. I already had an unbuilt World Models Ultimate 40 and the wing jig from that helped a bunch. Other than the shortcomings listed here, It's a fine looking plane and flys well. I wouldn't be afraid to buy another NitroPlane model. A new buyer will have problems if he doesn't know where to find the full instructions.

FYI: I was told to contact "[email protected]", once I did this I received a response the next day. The day after that I was offered a resolution to the missing jig problem plus a 25.00 certificate against any purchases for my troubles.

They try to rectify any problems. The hard part is knowning who to contact.

The WM plane is more expensive, and includes a few more parts (cross brace, pilot, etc.). But the Nitroplanes version is a good buy for the money IMHO, if you are aware of the differences.

I may just HAVE to get that Warhawk they have...

I've been eyeballing the 63" Chipmunk. http://www.nitroplanes.com/such5258.html

It does look nice doesn't it?

Yes it does. I'll order it in a week or two. I'm in the process of building a Mile High Xact. One plane at a time.

I flew the Nitro Models Ultimate tonight for the second flight. The wind was 10+ mph. 50 yards from the runway I saw something flittering to the ground. The plane was still flying well so I brought it around for a lookover. The right wheel and pant was missing. I flew around for a couple more minutes waiting for the wind to die off a little and to burn off some fuel weight. When the time was right I landed. The plane did well on landing but I slid it off into the dirt and it flipped over on it's top. I walked over and found no damage. The amazing part was I went looking for the wheel and pant. I found them after only a minute search in the thick sagebrush. Both were still together with the bolt and retainer. So far I haven't really had a good long flight to where I can really play around in the air. I did notice that the Magnum 52 with a 12.25x3.75 prop pulls this plane around with authority. Tonight on a landing pass I was coming down a bit fast. I gave the throttle just a couple clicks and it was more than enough to get the plane back into the air for another pass.

Here's another photo after tonights landing.

Ouch!

Nice moves on the stick to get it down w/o damage.

More member ratings for Nitro Models are showing up slowly. Another showed up today.

On my Ultimate 40, I took the wheel pants off. I'd installed regular axles rather than screws after the wheel fell off in flight and the the pants don't fit now. It looks a little more like a crop duster now.

My World Models Ultimate doesn't have the third center support like is mentioned in an earlier post. I might try making one for both planes.

Tim

Here's a good inflight shot.

I have a Magnum 52 mounted on the Ultimate 40 or 46 A NITRO PLANE. I found the plane to be extremely nose heavy. Has anyone had this problem?? This plane is not the best plane to buy by any means....[]

I don't understand the relationship between the weight of the nose with an oversized engine and the quality of the plane itself.

I put a .46 in mine and have had no issues with it being nose heavy.

The primary failings of the Nitroplanes version vis-a-vis other identical planes are:

- Lack of inter-carbane support strut
- Lack of alignment templates
- No pre-drilled holes in firewall
- No pilot figure
- Manual stinks big time!

I made my own support strut from stock aluminum bar... not really a big issue.
I was sent the aligment templates. These are a MUST, and should be included!
If you are electrifying the plane, the lack of the holes is a benefit. Jury is out as to the efficacy of this.
I put in a female pilot... sexier than the WM included cheap pilot figure...

So, yes the Nitroplane version is not as good as say the World Models version, but it is not a horrible plane.

If you are aware of the above, it's a cheap but decent Bi-Plane.

I contracted Nitro about the temp plates, and their answer was they didn't know but would contract the manufacture about the lack of tep plates, They have now c.g. but they did send me one number which then I found an review on the plane and found out that was wrong. I asked for the Flight control throws and received no answer.. No I'M NOT A HAPPY CAMPER WITH THE PLANE.[:@]

Tell them that you are missing the NEEDED templates without which you cannot build the plane.

Tell them that these are same templates that they have been sending out to other people that have complained as well, and they have sent these to others so they are aware of the problem.

You do NOT need to wait for the "contact the manufacturer" B.S.

As far as the throws, etc. download the "REAL" manual here:

http://www.theworldmodels.com/para/i.../pdf/A009S.pdf

I've got a 52 Magnum on mine also. I put the battery directly under the pilot seat, that helped the weight a little. I ended up with 1.75 ounces of lead on the tail. As for the quality, the plane is identical to the world models version. The differance is the partial instructions, lack of the templates, and a missing strut. I have the World Models version also. I had some missing hardware in the Nitro Planes version but it's hard telling where that went.

Personally, I like the plane. It's developed a radio problem so it's temperarily grounded.

thanks but the Nitro isn't worth the trouble. I'll build or buy a real plane from now on...

Well the issue of using an engine larger than the plane specs call for is a mood point (as proven in many forums here in RCU)
I fly high speed prop planes and scale model war birds and most ALL of them are over powered like a p-47 that calls for a 90 4 stroke and has a 1.20 4stroke installed the important thing to look at is the weight of the motor. The Magnum .51 weighs 15.7oz where the .46 2 strokes weigh: Magnum 2 stroke .46 16oz, O.S. max .46 17.2
Even the Super tigre .40 weighs 19.1

So the fact that a model calls for a .40-.46 is nonesense to try to say a model will only take engines in those sizes is also BULL when it really should reflect the engine weight.

UNCLE, IF others are using .46 2 strokes with no problems your engine chioce should be fine, your engine falls in the same weight class in not lighter! So the defect is either in the manufacture of the model or its classification of being a .40-46 size model is very misleading.

It's humorous to note that the original version of the WM.46Ultimate that is now being sold by WM and Nitro was originally marketed a year or so ago and did not sell worth spit. It was almost exactly the fairly popular model being sold today. Only difference was that it was originally MARKETED as a .30 size model.

Funny.... the discussion about overpowering this 46size model with something more powerful than a 46 is actually talking about putting something bigger in an airplane that was actually designed to be a 30 size model.

Yes indeed.

Not only that but the size of engine was being equated or compared to the build quality of the plane itself.

This is akin to saying that your car doesn't drive down the road very well, because it's blue.

Both may be valid assertions, but they do not influence each other.

e.g. putting in an oversized engine (or not) does not indicate that the model is poorly built.

As Darock stated the .46 pulls like a demon on this thing, due to it's size.

If you go larger, more power to you (litterally!).

But if you rip out the firewall, as a result, bear in mind that this was originally a .30 plane.

My point exactly, I was not aware that is was originally marketed as a .30 size plane that will make a world of difference now overpowering model can be done but it DOES have its limitations. And I strongly recommend that if you are going to over power a model do so only after you have reinforced the firewall

OPJOSE is right if ya pull the firewall out don't get mad at the model. Tis like putting a 454 in a gremlin, it may go like a bat out of **** but it will more than likely have an unhappy ending! Thanks for the info I did not know it was originally a 30 size plane!

With the 52 Magnum turning a 12.25x3.75 on mine, The Nitro version turned out to be a great flying plane. I may add more weight to mine a little at a time in the tail to see how it does. It's really a blast to fly as it is. It's very fast and very agile then at slower speeds it's just as smooth as can be with no bad habbits. It's a great wind plane, it'll cut with through a 25 mph breeze without flinching. It's pretty darn strong too, first couple flights I was expecting it to come apart being as fast as it is. I've not found any problems with running the larger engine on it. I need to get the reciever problem figured out in that one so I can get it back out to the field. It starts shaking once the motor is started really bad, makes for an interesting flight.

When I get the World Models version out of the attic I'll replace the stock 52 muffler with the pits version from Magnum. It's 1.75 ounces lighter.

Heh, you have both of them too?

I donw loaded the temp plate for the wing and found that the top wing was about 2 and3/4 to 3 inches to far back should help with the weight problem. The company should of send me a set when I requested them the first time. It would of saved me a lot of heart ache...But it is looking a bit better just a few changes and some extra holes..

Yes, I've been through this with them and there is NO EXCUSE for Nitroplanes to tell you that they "need to contact the manufacturer about this".

They KNOW about the problem with the missing templates.

You are not the first one to complain about it.

I also did so in May, and finally received the missing templates in June after many e-mail exchanges.

They gave me the same B.S. about "not knowing" and "we don't provide them", but I pointed out that they had already received many messages about the templates... and the need there of as per the documentation in the kit.

I got finally sent a pair of waay too thin templates, I ended up using the ones from my World Models plane. (Yes I had them, but it's the principle of the thing... so that hopefully others don't suffer the same fate...)

Yes I'm trying to have them send me a set also. I did down load the temp plates off the forum and they seem to work.. Would like to thank the person that put the pic. on the site... Will let you know how this turns out. I sure want to fly this... Thanks Everyone
