greetings
they are all great motors
care to share ur biased comments (for 3d + imac)
i need that info for my decision, cost aside
thx

I'm biased!! Mvvs and B60. both are run by stand up guys!! Evo I have never owned.

Never tried the others--no need to after flying my B60! Great motor and great support to go if needed--which is rare

I have an evolution 58 and it is the best running, easiest starting engine I've ever owned. It has great power turns a 24x8 prop at 6400 RPM.

Are you using the EVO muffler or a cannister to get those rpm's ? How much time on your engine so far?
thanks,

Dino,if your looking at nothing but all out HP the 58 has got the most power,and it is the state of the art design engine lots of (gizmoes) with the auto choke being able to see what your rpm's were in the air.the b60 is a time proven engine design very reliable, some people call them tractor engines. i was going to buy one for a EF yak but came across a 58 nib for 400.00 and had to take a chance for that price.very good support for the b60 you can't go wrong with one,after all if you can't depend on your engine your going to be flying around like a old lady!!

before I provide my Biased opinion....

What airframe is it for?
How much does it weigh?

3DDino

ef yak 88" ------8 kg

B60.

Because its lighter than the other choices and you want to fly 3d. Better to be light than heavy. I have my B60 on the 87" Yak and it has unlimited vertical and was hovering at about 15% throttle before I throttle curved it up to around 30%.

I was looking at the same choices you were looking at before I bought mine and was worried the B60 would still not be enough. However, the more I dug into the weight of the other choices the more I found it was starting to get prohibitive to work with. You might need need to put your batteries in the tail to make the 58 work....

Plenty of power with no weight penalty. My plane is an absolute "floater", like a gas foamy. I can cut the engine and it will just hang.

That plane your looking at is the absolute perfect match for the B60 for 3D.....
Plus it can be reused more easily in just about any other 28% without adding so much nose weight.

What a wonderfull un-biased post, Look at this another way, do you want an ugly installation or a neat one, carb poking out the side of the cowl or all smooth and hidden, your decision, they are much the same when you get too this capacity. Oh yes the MVVS 58 weight is 67onz without the exhaust, ignition is 6onz and it does not need stand offs usually, and it devolops 8.5 HP @ 6800rpm.

well the claim is actually 8.. but that is probably on a pipe like most of the other specs. Personally I'd have to see it to believe it.

Let's not forget there have been a string of problems with the engines as well...

Actually the HP claims don't mean too much. Hang a big prop on the motors and see what happens. That's what it's all about.

With the cowl space in the 88" Yak, you could put the B60 and MVS58 in there and still have room left over for a lunch bag for the day. You will not even cut the cowl for the carb. In fact, the side mounted carb with the new velocity stack now fits in my Yak with a cowl about half the size as that plane.

That weight is bogus (don't forget your going to need a spark plug too [&:])....dig deeper.....call the company up and pin them down on the AUW....thats what I did. Your going to need a sack of potatoes in the tail.

Ih82crash

Horsepower numbers don't mean much to me while I'm flying. All I care about is performance. My 58 has a stock Muffler and is on an Aeroworks QB Yak (18.5#). When density Altitude reaches 7800 ft. (Which is often) I can still pull out of a hover with authority. I am not using the auto choke feature I have the choke set up on a HS 81 servo and plugged into the gear channel. to start it the first time for the day I close the choke and flip the prop twice. then I open the choke and flip it 4 times. finally I turn the ignition on and it fires up on the first flip of the prop. after that It starts first flip for the rest of the day. I have about 6 gallons of fuel through the engine now. I have a brison, two 3W's and an evolution 58 gas engines. Out of them all, the 58 starts the easiest and runs and idles the best. In my experience a 24-8 NX is the prop for that engine.

BaldEagel

The weight is not bogus I have an MVVS 58Pro and it includes the spark plug and the rear mounts and all six of the prop bolts and the centre one. Not run in fully yet only two gallons through it, and its turning a 22x10 three blade at 6850rpm.

I called MVVS Canada directly and when I was all done with muffler, standoffs I was right at 4.9- 5 lbs. Also, as I recall their mufflers were HEAVY--research it.

I think Scott said he was turning over 7000 on my motor running a 22x10...with only 1 gallon through it. And 7700 with a Xoar 22x8.

3DDino

Looks like mvvs58 is heavier but has more grunt
why they say theres no replacement for displacement 58cc vs 60cc
thz

BaldEagel

The MVVS does not need stand offs as the mounting is at the back of the engine, not half way along the crankcase, the cannister mufflers are heavier, but much bigger, quiter, and add power, putting a pitts restrictor on any engine IMO is an all around loss, restricts power and are noisy.

I don't have to research it I have one in my hands. Don't belive all you read or are told, Oh yes you are already doing that except on the phone. Move on.

Let's not forget power ratings on these motors are with the pipe. Also the 58 is $100 - $200 more if you use that pipe.

366GT mounting is not half way along the crankcase... it uses rear standoffs like majority of the engines out there.

Because all the magic technology you might think of to get more power, at the end of the day, displacement is still the king.

BTerry

My Feedback: (8)

If you really want to get into this argument about displacement vs. technology 3d and BaldEagel, my ZDZ 80 weighs 150 g more than the MVVS 58 and has a rotary valve. This puts it in the same weight range as the B60 and MVVS 58, and maybe even lighter with a Pitts muffler vs. the MVVS tuned system. Oh yes, old, wide-blade (HEAVY LOAD) Bambula 26x10, 6500+ rpm, at 4250 ft elevation.

The MVVS should have a considerable advantage at low- to mid-range torque, and will feel more "alive" at lower RPM or a larger diameter prop. I haven't seen any proof that the B60 can keep up with the MVVS 58 on a 24" prop, although it tops out higher than on smaller props.

3d-aholic

My Feedback: (7)

The B60 weighs way less AUW including a muffler than a MVS58, so if you motor weighs even more than a MVS58, its not even flyeable. I myself would find the MVS58 nearly unflyeable on my plane because of the weight...a ZDZ80 would need a ton of weight on the back to balance.

Most of the similar props show the B60 doing the same as the MVS58.....like you said, but haven't seen anyone try a 24" prop on it. I was planning on trying a Mez. 24x8 on mine after I get past 8-10+ gallons and well broken in. I wouldn't expect either of these motors to keep up with 80cc's though.
