Hangar 9 1/4 scale Taylorcraft motor options?
I was going to put a 3W-24 on mine, but I abandoned the project after about a month since it was getting more and more difficult. Nearly impossible to get to the carb with the plane set up per the instruction manual. I actually sold the 24......bought a FPE 2.4. This is a perfect combo. I don't think the 24 would have been strong enough for my liking anyway.
I had a Saito 1.50 in the plane previously, which was a good combo. I decided to go with gas in all my planes......so out it came.
I'd say that the FPE is slightly stronger, but much faster with its 19x10 prop. Not unlimited vertical, but very close.

I have a MA 20x8, but it will only spin at 6250rpm on the ground....according to FPE the Mejzlik 19x10 pulls stronger at 6900.
If I had a Mejzlik 20x8.....that might be the way to go.

Was getting very low numbers with the FPE 2.4 standard ignition and ma 20x10 6100 rpm switched to ch ignition and 20x10 mejlik 7000 rpm and the same numbers with menz 20x8. This was with the standard muffler, which requires less cutting on the cowl than a bission.

Dave, the book calls for 6 1/4 to 6 1/2". Mine with the Fugi 32 and long B&B mounts is at 7 1/2". the backing plate sticks out about 5/8" and the cowl is moved forward some. The stock setup looks better.

The FPE 2.4 with std ignition is no powerhouse, but it's the lightest 40cc available. The CH ignition upgrade gets you another 0.5 hp and 2-3 lbs more thrust. G26 and 3W-24 are under powered by about 1 hp. The FPE weighs within 2-3 oz of either of those engines!
The plane balances perfectly with the FPE: ign battery just behind the firewall and the rx battery on the tail end of the radio compartment. I have a slightly heavier ohio r/c tailwheel installed, as well.
The saito 1.50 required lead in the front, I originally compromised and left off the tail braces in order to balance.

As I've posted in other threads, I also have a Taylorcraft with a Saito 1.50 in it. I also had to add 20 oz to the nose to balance it, but if I had built it (I bought it used) I would have mounted the engine and cowl further forward, so I could get away with less.
This combination is probably underpowered for flying Pattern, but not by much. On the other hand, it's not meant for modern competitive Pattern flying, anyway. You guys talking about 40cc gassers must be attempting to fly 3D maneuvers (which it wasn't designed for *either*), because that's *way* more power than this model requires. Of course, whatever floats your boat...

I'd say that a 40 cc gas is not over-powered. My FPE produces about 18 lbs of thrust according to thrust HP......and that program tends to over-estimate thrust. Like I said, my T-craft weighs 15.25 lbs, and does NOT have unlimited vertical. It's just enough reserve to initiate almost any maneuver from any altitude or airspeed. I can do a hammerhead stall turn from a touch-and-go if I want to. And I do.
Locomotive.......I'd guess that the Brison is more powerful than the FPE with its standard fixed-timing ignition. It's probably a wash if compared with the FPE with the upgraded CH ign.

Errr...this is a scale aeroplane. Not only is it a scale aerobatic aeroplane, it's an antique scale scale aerobatic aeroplane. the aerodynamics
features of this design do not get better with more power, 1-1 power ratio is simply way over the point of good taste.
Things do not necessarily get better with more power, infact quite the opposite. A Cub for example just get worse and worse for every extra cc you add over the design peramiters. Taylor craft aint that much different.

Dodge Dart GT
Well, it's true, different strokes for different folks. We all get our jollies in the hobby different ways because we have somewhat different interests and motivations within the hobby.
Some people really liked the Dodge Dart because it was a nice little pedestrian family car. Others realized it could be a great lightweight platform for a lot more fun if a small block V8 was stuffed into it. The Dart GT was a blast.
I've found that my T-Craft is a heckuva lot more fun to fly if it has a little bit more power-to-weight ratio than with a G23. For the record, the 40cc gassers are about the same power as a Saito 180. Horizon strongly recommends the Saito 180 for this plane. My BME is slightly more powerful still, but I've added more features to the plane that make it weigh more (18lbs) so that the BME is very nicely suited to it.
BTW, I agree that overpowered Cubs aren't much fun, as I had a 40 sized one that way. It flew better with a Saito 56 than the Surpass 91 I had in it initially. But I still hate the way Cubs fly and sold it.
IMHO, "Flying Scale" is for purists who are motivated by scale realism. That's really cool, and it's fine for those folks and I have no disagreement with that motivation. I am not a scale purist, though. Many of us here are not.
However, sometimes "flying scale" can also be a defense mechanism for people who simply don't happen to have a more powerful engine at their disposal.

The way I sees it....flying scale is better suited to full wing planes. Clipped wings are for hot rodding. Very similar to the Dodge Dart analogy. I also fly a Patrick Ultimate with a YS 140 DZ. Under powered planes scare me.

And by the way, clipped wing planes are for more aerobatic performance, not neccessarily for *faster* performance.

HP
Not to get into a major discussion (or argument), but I compared the thrust and mph calculated by ThrustHP for my Saito 180 and my BME 44. From what I know, the ZDZ40 is little less powerful than my BME44. For the ZDZ, we are comparing a 2.4 gas vs 1.8 4C glow.
Note: Thrust HP is not terribly accurate for absolute numbers, but it is usually pretty reliable for comparisons.
Saito 180
- APC 17x8 9400 rpm (30% fuel)
71.2 mph, 22.1 lbs thrust - 3.96hp
- APC 17x8 8900 rpm (15% fuel)
67.4 mph, 19.9 lbs thrust - 3.37hp
BME 44
- MA Classic 20x10 7200 rpm
68.2 mph, 23.5 lbs thrust - 4.27 hp
So, looking at the data, and having actually flown the plane with a G23 and a BME44, I don't quite see the speed issue in terms of ripping the wings off. Horizon recommends the Saito 180 on their site. There is not a huge difference in speed, although there is certainly more thrust available with the gasser by swinging a larger prop. If you actually saw the plane fly (like I did with some other veteran flyers) you'd realize that it is far from overpowered.
