Here is the video of my 176 when I first got it and ran it up on the stock mufflers and a Mej 30x13 EvoL. I later tried a set of KS 95 cans and the rpm jumped to 6250.

This is my observations.

For torque and throttle response and lightest weight , the zdz 180 hands down. It's a beast.
GP 176 EVO, good throttle response but doesn't have the low and midrange torque of the zdz.
The GP 176 would unload in the air to within a 100 rpm of the zdz at full throttle. But took a few extra seconds to get there.
Out of a hover, you could feel the GP was loaded more. It wouldn't rev out fully like the zdz could.
Throttle response on the same prop wasn't quite as instant and crisp as the zdz.

Now, all that said......
The GP is a much easier engine to run. Easier to tune, easier to start, a bit smoother running. Doesn't hit as hard. It is a solid reliable motor. Fuel, flip and fly. Over and over

I wouldn't hesitate to own another one if I went back to bigger planes again

Curious what exhaust systems were on the two engines.

I was using RE3 pipes at the time . Plane Bender didn't have the large Smooth pipes then.

The plane was an EMHW 50% Ultimate. Weighed in at 48 lbs
Flying around carving big lines. I flew with a Falcon 32x12 carbon. For slower 3D type flying, I would use the Falcon 32x11 wide.

Is the GP176 & smooth pipes combo usable for 3D or should one better go with cans instead?

I was concerned about the same thing but hence the name "Smoothpipe" is worth its weight in gold. Unlike most tuned pipes the mid range is fantastic. I am a low and slow 3D person so mid range is really important to me. One thing I tell people is if it's a new engine don't judge the smooth pipes until you get about 10-15 gallons threw it and it's fully broke in. I actually broke mine in on cans for 15 gallons and then went to the pipes. I have seen a couple others use the combo with positive results. Planebender can give you great tips on tuning for them.


The smooth pipes are usable for 3D IMO.

Agreed
I have had the 35cc pipes on a da 70. And the medium smooth pipes on an eme 60, DA60 and GP 61.
no issues here. Very user friendly for slow 3D.
A buddy f mine has large smooth pipes. Used on an mvvs 190 quad and a GP 176 EVO.
And another friend had a large smooth pipe on a zdz 90.
They were all easy to tune and fly nice 3 D with .
