RE: ZDZ 80 setup on 2.3 comp-arf
Are you letting the cat out of the bag? Have the Extreme Flight 87" Yaks arrived??????? and why use the ZDZ 50 and not the recommended DA-50?

Hey Dick who do you think that you are kidding? I thought that you were going to set the facts straight.

Nice CW!
Dick, I apologize, I read that on some dudes hobby shop web site that you are a ZDZ engine "Evaluation Expert". No offense intended. Here is where I read this,

RE: ZDZ 80 setup on 2.3 comp-arf
My 2.3 came in last night, incredibly, there was no shipping damage. Everything is very clear now how to do the ZDZ now that I have the parts to look at. Does anybody know where I can buy custom machined standoffs?

RE: ZDZ 80 setup on 2.3 comp-arf
I also recently published a write up on the DA100- for 3DFlyer-
The reason we setup the ZDZ80 -not the DA50 w/pipe. is that the plane is in our opinion -simply too heavy for 3D stuff -at out elevation .
A 50 with a pipe can be a very strong setup -jut not as strong as the much larger engine.

I have purchased a couple sets of standoffs from [link=http://www.aerografixs.com]Aerografixs[/link] (I think its called Forgues Research now).

RE: ZDZ 80 setup on 2.3 comp-arf
OK -for those who are actually doing the ZDZ80/in cowl muffler as I just did (customer's),
here is the final setup:
with 2700 ma Expert batt - 8411's 6 of em and two 517's (throttle and choke) - 32 oz tank 3.375 TT spinner and a 24x10 MenzS prop--1200 ma ignition batt.
No lightening mods or CF tube etc..
19.5 lbs exactly -- balance is 6" aft LE of wing.
So I don't know what the DA 50 w/pipe setups weighed typically (except for one) but I suspect it is fairly close.
One thing for certain
Incorrect power use could like tear it up.

RE: ZDZ 80 setup on 2.3 comp-arf
Thanks for the setup specs Dick! 19.5 lbs seems reasanble for this aircraft with the 80. I think most folks would be satisfied, including myself! Where did your receiver battery pack end up? Also, why did you go with such a small spinner, I was going to go 4" Tru-Turn, just curious?

RE: ZDZ 80 setup on 2.3 comp-arf
The 3.75 fits perfectly -- if I lowered the engine .125" the 4" spinner would fit---
so-------- it was where I had the engine mounted that dictated it.
also this spinner is extremely light.
The CG will be finalized after flying it - the Rx is about 6" aft the wing tube - batt is on the tube

RE: ZDZ 80 setup on 2.3 comp-arf
It sounds like you are maintaining serious distance between ignition and radio components. How close to the ignition system is the throttle and choke servos? The reason I am asking all these questions is this is my first gasser and I want to get the details right from the get go!

Oh yeah, how much right thrust did you end up with Dick? It appears that the motordome has a bit of right offset already built in.

Yeah, I have a set of blue on my Laser and Brison 3.2 combo. The engine case is anodised blue and the planes covering is blue so it makes for a good looking setup. They are nice and light also. Good luck with your project.

RE: ZDZ 80 setup on 2.3 comp-arf
My 2.3 DA50/pipe is 19lbs 6oz. Dick, what is the weight gain if using a JMB canister? I've become pretty addicted to my quiet piped setup. It sounds wonderful.

RE: ZDZ 80 setup on 2.3 comp-arf
Well -my scales are right -and I am only 2 ozs heavier ?
strange -
anyway the JMB which works best on a 50 cc engine --weighs -9 ozs (I just weighed it .)
but on my ZDZ50 - on Mejzlic 22x10 ---it runs 7100 rpm.
My pipe runs over 7400 and weighs only 14 ozs --
I just got a new pipe to test which weighs 11 ozs - the KS pipe weighs somewhere between there.
This is at our elevation but all in all it should correlate with sea level -especially now at 40 f outside.
I just came in from doing test runs on the new pipe -so all this is fresh info

RE: ZDZ 80 setup on 2.3 comp-arf
Bump...
I am building this combo and wanted to keep the thread going... Any new information out there?
What size fuel tank are you all using for the ZDZ 80?
