As I prepare to re-enter the world of C/L Stunt after 34 years, I have been overwhelmed with the number of good models and motors available.
I will probably go with the UHP Gieseke Nobler out of the chute and probably move up to the T-Rex, although other planes also interest me. At this point in my life, building one of my own from scratch or even from a decent kit isn't too appealing. If I scratch build and the plane is a squirrel, I won't know if it was me or the wood. ;)
So I will go ARF and hope it isn't BARF. I will have on hand the following new engines:
EVO .36
BRODAK .40
OS LA .46
Supertigre G51
Plus, I have 2 old OS MAX .35's that I will probably send to Big Art for eval.
These will probably cover my needs whatever size I choose to hook a handle to.
I have been in touch with Al, Les McDonald and Bob Hunt. They all were encouraging. I spent over an hour on the phone with Bob and he did his best to convince me to "say no to glow" in favor of watts on the wing. (Sorry, Bob. I have to see if I can still fly before I go sparky.)
My next step will be ordering the Nobler, sometime after my wedding on the 24th and the cruise to Bermuda the day after. When we get home, there will be motors on my doorstep. Life is good.
Now, to decide if I carry the bride over the threshold before the motors will require deep thought... . mw~

The ultra hobby nobler and a randy smith aero tiger 36 would be your most potant performer off the shelf . Yeah screw the electric thing . Next you have to be a battery geek . chargers , battery packs dischargers power supplying yikes ! no thanks, prime flip and fly for me too.

With what you have, the Brodak 40 will be ideal for the G. Nobler.

Check this out after 34 yr's things have changed, Now we have Motors & Engines I see no motors in your list but Engines I would use the OS LA 46 , Welcome back. Think about Motors in ECL !

On the other hand, the one UHP G.Nobler ARC in our group has a B.40 and sadly needed 5 ounces of noseweight. I don't know if that is a common problem, but it's apparently possible. The B.40 is a nice light engine, but suffers somewhat from having a unique muffler bolt pattern, and not that many muffler options. The OS .46LA has an extra couple of ounces to start with, and many mufflers fit, so it's easy to adjust the CG with a muffler change. Worth a thought, especially since the .46 doesn't (in itself) require larger lines anymore.
I would suggest having the engines safely squirreled away beforehand, so's you don't stumble on them when you carry the new bride through the doorway. But maybe just softly kick them inside first? Good luck with that wedding and honeymoon stuff! :-X Steve

Aah, busted. I should have covered all bases by using "powerplant" which is as generic as you can get. HB~>

Yes, I have read that and I had planned on giving the heavier EVO .36 a shot before adding weight. I also considered the OS LA .46, but Steve Moon advised that the larger prop on the .46 will be a problem with ground clearance due to the existing landing gear. I also believe in following the manufacturer's recommendations for engine size, in this case, .35 to .40.

Fellows remember Bob designed these planes around the old trusty Fox .35 Stunt that may have been chosen for him to power the planes. In my ARF Nobler I ran the Brodak 40 for break-in in place of the Fox 35 Stunt I had in it. Had no problems with balance and the plane flew great, but, has the Fox back in it as the B-40 went into the Olympic I used to have. The B-40 is I think the lightest of the 40's I have ran. I would not even consider running a LA 46. My opinion, DOC Holliday

If they tend to build tail heavy, then that is something to consider in engine selection.
However I don't have any problems with muffler selections. On my TF Nobler ARF, I run the B40 with a tongue muffler (which is available from at least 2 sources (since I have 2 different ones!), and on my P40 ARF, a considerably larger plane, I run the B40 with the stock muffler (this was the later version of the stock muffler with a larger exit hole compared to the stock muffler that came with the B40 on my Nobler. The Nobler and the P40 balance fine with those combos (which is why I went that way).
I have no experience with the UHP G. Nobler, so I am not sure what is going on with the balance. I don't think it is a "feature" to come out nose heavy--unless the design was changed to allow the typically heavier modern engines without adding tail weight!
With regards to props and the LA46, I would certainly look at 3 bladers as an option to absorb the power. As a first choice, I would try one of the MA 3 blade props. They are "rumored" to be underpitched so I wouldn't be too scared away from the available options.

I'm in agreement with Doc; the LA 46 would be too much engine (not motor) for a Nobler. Years ago I built a green box Nobler powered by a McCoy RH 40, it was a good combo. I did add about an ounce of nose weight as I recall. My experience with the B40 is limited, but the experience says it's a very stong 40 and would be plenty of power.
I sure hope your bride loves the smell of castor oil n~.

I have a UHP GNobler that I used an OS 35S in with a tongue muffler and it balanced just fine with no added weight.

How did you like the kit and how does it perform?

Hi Dick,
I would think that the UHP Geiseke Nobler will be a fine model and not a BARF. ;D
As to engines, anything from a Fox 35 on up will probably do a good job, but just how good of a job do you want done? If you want the best possible choice (in many people's opinion), get a Aero tiger 36 from Randy. I have heard it called the best stunt engine for its size on the planet, and by several top pilots at that. I know it has been Billy Werwage's powerplant for his Classic planes since it came out, winnig a few VSC's with one in his '62 Ares.
As for the lesser priced engines, any of them should be good. The Brodak .40 is nice and light, a touch stronger than a good OS 35S. The LA 46 is a popular choice for many people in th older Classic *35 size* planes. Just how much is *too much engine*?? Who knows! If it is too heavy, or you cannot get a prop to clear, can't carry enough fuel, etc., then that is a problem, obviously. But too much engine? If so, why does David Fitzgerald run a piped .75 in a design that can easily (and has) fly with a piped .40?
The ST G51 has been used by Tom Dixon in a '59 T-Bird, and flew quite well with no problems. A lot of people forget just how much nitro guys like Billy Werwage and Steve Wooley ran in their Fox 35s.......
