RE: Brillelli 46cc
Artisan,
Over 17 high dollar engines?? What do you do for a living, rob banks.. LOL ..Your point is well taken...
For certain applications, in certain planes, for certain conditions, a particular engine will be right for that occasion.....Apparently, that's why there is a ton of engines available in the gas and glow market, from weedeaters, to precision , purpose built engines.... What a deal for us in the sport, competition and price......

Zippi: I just had to kid around a little with that. From what I have see....the Brillelli engines are very well made. I got one my too!!! Capt,n

RE: Brillelli 46cc
I don't need someone's resume to decide whether I can interpret English when written. Happy that you shared you half-vast inventory with us, I'm sure that is quite helpful to someone wanting to contribute to this thread on the Brillelli 46.
"Not purpose-built" makes a lot more sense to me, appreciate your clearing that up, although I don't care about your opinion on the "state of tune" of the Brillelli motors a whit. Hope you like all your motors.
I like all of mine... and the 46 seems to be a very solid performer in it's class.

RE: Brillelli 46cc
boy o' boy can't we all just get along!!!!!!!!!
to be honest with everyone though, there is only one purpose built (engine) and the company name is DA they are the only company that has built an engine for RC... But DA is very expenseve compared to other company's that produce same quality engines for a 1/3 of the cost.
by the way (engine) is an enternal combustion piston driven, where a (moter) is made of magnets, coper windings and ran off of electric.

RE: Brillelli 46cc
I think you can have an air powered motor too... j/k.
I ran my 46 with a 21x8 today, down from a 22x8. It went from about 5600 - 5800 (22x8 xoar) to around 6600 rpm wot with the 21x8 xoar. I can hover my GP Yak 54 with the 21, but with very little pull out (but GREAT performance otherwise, great acceleration!!). I have run 1 -2 gallons through it at this point. Will the engine get much stronger after more break in? The web site says 6500 with a 22x8 which would be pretty darn good.
Also, the engine is getting a lot of positive interest at our club - the performance as well as the price. Even from the big boys who drive 40% Cardens with DA -150's.

RE: Brillelli 46cc
Well I dont think your engine is tuned right... you should be getting more then 5600-5800 on a 22x8 any day. Mine turned a Mezjlik 22x8 at 6900 after I think 3 gallons. New it was sitting at 6600 or so.
From my experience every rpm quoted by Scott has been low on every engine I have gotten from him. He tends to be more conservative then anything.
I would suggest getting someone with a good tac and readjusting the needles. That engine should hover that Yak nps and have decent pull out.

Artisan,
All of the engines you listed except a couple are "utility engines" Zenoah's are all utility engines. New crankcases don't count remember ? The BME is a chansaw engine just like the 46. most of the engines out there are derived from a Utility engine. Taurus, Brison, , Fox, and MANY others.

RE: Brillelli 46cc
Ucas,
It sholuld be in the 6400 range for sure with the Xoar 22x8. I would do a little leaning. Lean the low until you lose transition. Then richen the low until it comes back. Then peak the high. It may not lose transition on the low, but it will be easy to tell if it is too lean by how it starts. They start harder when too lean on the low. Let me know what you get. That extra 400-500 RPM will make a huge difference in thrust and pullout.

RE: Brillelli 46cc
well no disrespect Joe but either your engine had a small issue or it wasnt tuned right. I flew with a 22x8 at 6600 from day one and she pulled like a champ

RE: Brillelli 46cc
The problem with RPM numbers is it can vary greatly with different temps, different elevations, different gas, and different oils. I typically get 6200 to 6400 on a Xoar 22x8. I never tried a 21x8. But here in MN I am pretty low in elevation and I use premium gas and a 40:1 mix of non synthetic oil for test running. And hey, it is cold here

RE: Brillelli 46cc
The engine JoeAirport is talking about is actually mine. It has a total of about 1/2 a gallon through it and 3 flights. First flight was with a Zinger 22X6. About 6800 RPM but the plane flew VERY slow. Plane is a Bipe and it likes a little speed. Swithched to a NX 21X8 for the next two flights. Plane flew much better with that prop at a peak of 6600 rpm that Joe mentions.
Now, I have not touched the needles since I got the engine from Scott. I did however remove the velocity stack. Engine ran fine but it could be a little below peak rpm (400-500 rpm possibly?) and running a little rich because I took the stack off. It did exhibt a little brubling while flying. Since I only got to fly the plane three times and had an unfortunate incident while landing after the last flight, I didn't get to mess around with the engine at all. Plane is all fixed by the way. I would certaintly like to get 6400-6600 rpm's out of a Xoar 22X8 since I have read nothing but good things about that prop, no personal experience though. Since I broke the prop (NX 21 X 8) mentioned above during the unfortunate incident the Xoar maybe the next to try.
I know the 21X8 Nx is good, maybe the 22X8 Xoar could be better.
Incidents will happen when you try to fly in a 20 mph wind gusting to 25 or more.....be careful, keep that speed up when landing...also Fall turing to Winter quickly in southern WI so it might be next spring before I test fly more.
Last thing, glad to see this thread get back on track talking about the Brillei 46 and thanks again for a great engine and service Poco242!

RE: Brillelli 46cc
Hey, I was wondering if you got that plane up again after the 40cc. The 46 should give it more power for sure than the 40 did. I don't know what gas you are using, but I like to use premium around here. In MN anyway if it is anything but premium it has alchohol in it. It seems the premium makes a little more power being all gasoline. Also taking the stack off will change the tune quite a bit. It will need some tweeking for sure to get it dialed in. The weather has been so crappy here I think winter is comming early. You may need to put some skis on that plane soon

RE: Brillelli 46cc
On all of mine, without the velocity stacks, the needles are really RICH (as received, before I tweaked it down)... particularly the low end. Lean that thing some more, you'll get a lot more power out of it, not to mention less burble, and a LOT less shake.

RE: Brillelli 46cc
Bob likes a 21x8 on his 46. I think the rpm increase on it may make up for the 1" in diameter as far as thrust goes. I need to order a 21x8 to compare the two so I know what the heck I am talking about

RE: Brillelli 46cc
I don't think ZDZ or MVVS were listed in the "purpose built", either, but no matter... this is a Brillelli 46 thread and it's use.
The three that I have run (all on Ultimate biplanes) really do very well with the 21 x 8's, both the BME and NX. Didn't get to try a Xoar yet, as the new project intruded on my Ultimate with the 46.
The low end needed leaning, and all of these break in enough in the very first few runs to need the low end readjusted. It is easy to tell when, though, because when the low end is too rich, there is a definite, and easily heard, bogging down on rapid advancing of the throttle, and it is a different sound than if too lean. Not to mention a LOT of shaking at idle.
Small low end adjustments profoundly affect the vibration and smoothness. It also really helps to have a very precise servo/pushrod setup, and to have the geometry of the carb arm such that low end movement has very good mechanical resolution.
Wish we could do "sound tracks", because these audible clues to the tuning of the carb really are what helps me get it right.

-------------
I have nothing against your engines, which should be obvious because I just bought three of them in as many months, or so. I am well pleased with my Brillelli engines. That is official. I have alluded to nothing else in any of my posts.
Now, compared to a Yamaha Grand Prix 5-port two-stroke engine of a few decades ago, do you think that your engines are in a "high state of tune"? That is what I was referring to. It wasn't intended as an insult, deprecating comment, or derision in any manner. It was a statement of fact.
If I didn't like converted utility engines, I would not have owned so many Zenoahs, Homelites, Ryobis, Echoes and Poulans as you have pointed out. What we have here, is failure to communicate.
Since everyone is having difficulty reading lately, NO, I do not consider your engines to be in a high state of tune. I do consider them to be tuned optimally for their intended usage.
I AM A HAPPY BRILLELLI CUSTOMER! And I have said nothing contrary to this anywhere at any time.
Now, where do I get my official "Keeper of the Brillelli Flame Badge and Membership Card"? <G>
