well i would like input on this engine as i might get one for a 16lbs plane i have now will the vertical be good and the 3d performance

The Brison 3.2 is a good engine and will certainly have enough horses for 3D. Getting one may take awhile though.
I would suggest the BME 50. You can get one direct from Kieth at BME or Don's Hobby for $499.00 without muffler.
You won't go wrong with either engine.

fox 3.2 would be a great match exelent quility the best service,and no i do not work for them just my experience.

Another good choice would be the ZDZ 50 that just came out.

Gary Allison at Brison has production squared away, and it should be no problem getting one. I have a Brison 3.2 in a Kangke Laser @ 16.5# and the vertical is unlimited. It will accelerate straight up from a hover to flight speed in about 2 seconds and continue to accelerate till my old eyes can't see it. I'm using a 22/10 Pro Zinger, A 22/8 Pro actually performes a little better but its noticably louder {a problem here in north west NJ}.

I've got a Brison 3.2 and if you attach it to a 16 pound plane I'm confident that it'll pull it straight up 'til you tell it to go somewhere else. I've got mine on a 17 or 18 pound plane and with only two flights, I haven't had it over half throttle yet. I've run about 3/4 of a gallon through it and it turns a 20 X 10 at 7800 rpm. Idles at a shakey 1850rpm. This engine is not nearly broken in yet.
It IS loud. I finally broke down and ordered a Bisson pitts muffler for mine. Hope it helps.
I'm sure any of the high quality gassers like the ones named above will give you about the same performance.

While we're talking price, the ZDZ-50 costs the least..... $450, and it already comes with the electronic advance ignition. You just missed the "sale" at $425. Muffler costs extra.

the fox comes stock with syncrospark , if prop noise is a problem you can use a PK plus prop it has better pull at a lower rpm great prop

Ditto the Fox, great engine. If I remember the ZDZ does not have C&H ignition, and doesn't it have that six bolt prop hub?

Ya Vince:
The ZDZ has the Falkon ignition, which some may feel is better than the CH. It has a hot spark, is reliable, and has a fully shielded cap and wire. On a CH, you have to pay extra if you want shielding.

Also, 6 bolts are for "real" engines....

In your opinion I will put a properly run-in Fox or Brisson 3.2 against any ZDZ of the same size, single bolt prop hub and all.

That engine is a wus

I have the Brison 3.2 on a 19 lb Stinger. Std takeoff is 25 ft roll then straight up. If "I" could hover it, then it would hover. I have done stop-n-go manuevers on the upline. I was considering putting it on the Lanier 232 ARF to get a lighter, more 3-d'ish machine. 22x8 pro does it for me, although I hear some of the top-end props perform even better.

Never owned a ZDZ-40, but have had a chance to take a good look at my buddy HT's motor. I did set the needles on it and point the tach. His turned a Mejzlik 20x10 at 7600 rpm. My Brison 2.4 would turn the same prop 7100 rpm. I have a Brison 3.2 and have put the tach on a couple of others. The best one turned a Mejzlik 22x10 at 7200 rpm. The "weaker" one turned it about 6900 rpm.

Haven't seen a ZDZ-50 yet.....too new.
But, considering that the 40cc motor is stronger than the Brison by a healthy margin, I'd be surprised if the ZDZ-50 also wasn't stronger than any of the Sachs-based 3.2 motors. In the HP/$ war, I think ZDZ has 'em beat.

The Brison 3.2 is a good little motor, maybe the best for power/weight of their line. The only trouble is that the design is getting a little old and the competition keeps pushing forward.

I have a friend with the ZDZ-40. By he numbers he claims, it must just about equal the power output of the 3.2. THe -50 would be huge if performance scales up by 25% with volume.

i have a 3.2 on the plane to the left. Its an AeroWorks Edge unlimted verticle is what brison says up to 18lbs. I am around 16 lbs with nci batteries i have unlimted verticle running a 21 x 10 mezn at 6900. I will be switching back to a 22 x 8 here soon as i plan to try some imac. The motor will let you hang on the prop of fly unlimted if you so disire. Hit me up if i can be of any more assistance.

The Brison web site claims 26 lbs of thrust with this engine. Of course, who knows what prop combo that might have been on. I'm sure that the thrust with the 22x8 is easily over 20 lbs by the way my stinger flies.

Krazyc; What is the difference between the 2 props you mentioned? Is the 21x10 better for 3d?? - why? I've been propping for best verticle, and I'm wondering if there'd another reason to use a higher pitch.... Better response??

I have owned and flown both the 3.2 and the zdz 40 on a Hanger 9 Edge 540.

The Brison web site claims 26 lbs of thrust with this engine. Of course, who knows what prop combo that might have been on.

I tach 6900 on a Menz 21 x 10 and 7200 on a 22 x 8 Menz, 7500 on a 21 x 10 Mejzlik, 6300 RCS 22 x 10, 6200-6300 22 x 10 Menz, 6150-6200 22 x 10 square tip zinger, Bolly 21 x 8. All the props have unlimited vertical. I went to a 21 x 10 only because the plane look like it was going very slow to me when flying with the 8 pitch. I switched from the 22 x 10 props because Gary at Brison say to keep the motor prop between 6500-7500 static. He felt the lower 6 grand figures were bogging the 3.2 down. She was easy to T-Roll with all the props especially the 22 inch props. You can easily get the 26 lbs of thrust that Brison claims with most of the 22 x 8 and lower props like the 21 x 10 and such. I am going to try my hand at IMAC so I am going to go back to a 22 x 8 and see if the routine looks better with that prop. The 22 x 8 Menz had the best down line braking. I could actually take the plane up 300 feet do a 4 point roll to the left and pause and do another 4 point roll in the other direction and still have 125 feet of air left. I figure this may be the ticket for the IMAC moves of 2,3,4, 5 and so on point rolls. The 3d was easy with 8 pitch, I just felt the plane was slow. Best example with the 8 pitch about 45 MPH top speed with the 10 pitch props about 60 MPH. I get to fly the 10 pitch props at 1/2 throttle or less because of the more pull they provide. You will love the 3.2 with a peacekeeper muffler as the other one is very loud to my ears while flying. The peacekeeper along with lower RPM and a 22 x 10 is so sweet. I will also be tring out a 22 x 8 Mejzlik. talk with you soon ....

Hey, that's good info.

I have a Stinger, and the wing wasn't reinforced for extreme maneuvering, so I'd just as well keep the speed down - and stick with the 8-pitch props.

Mine does 7300 on a 22x8. I think Menz makes a 24x8, hmmm...

I have a Brison 3.2 and a Fox 3.2 - both excellent engines but I like the brison a bit better for some reason.

Just for your info, I did have my Brison 3.2 mounted in a 26 pound plane, and it would hover it on a zinger pro 22-8 and just barely climb. So, it must be putting out at leasy 26 to 27 pounds of static thrust.

My fox is mounted on a 20 pound plane and pulls it around with authourity. On a 16 pound airframe, MAN that would be SWEET!

No experience with the ZDZ but I have a hard time to believe the 40cc will outperform the 52cc Brison.

There are too many good engines now to choose from, and everyone has a preference. I think you will be happy with any of the well known brands (BME, Brison, ZDZ, Fox, etc).
