I'm finally gettin started on the assembly of mine (bought it already completed, so just engine, servos, batts and receiver) and wanted to see if I could pick the brains of those running the XYZ 53.

I copied somebody's mount idea:

But, wanted to see if someone could give me your distance from firewall to engine mount flange and firewall to hub.

Also, any cooling issues on the XYZ, and how much weight (if any) did you add to the nose (understand this depends on a lot of variables...just looking for a ballpark)?

Any help would be much appreciated.

pm me and ill give you my email i will pull my cowl of and show you how to mount your motor the spacer that's required and a better way to mount your cowl allowing air for cooling. Has your xyz got the normal plugs or the smaller ones? the smaller ones are better for clearance.

Ran mine today! I want to thank Charles for the great work he did on the plane before I got it from him and Frank for all the info he sent me.

You may notice I've got the stock plugs/caps on the engine. I wanted to run it in stock form first as a baseline, to make sure everything was working before I put anything aftermarket on there.

The XYZ 53 ran great...very smooth with a nice sound to her!

There's a much longer thread here on rcuniverse. Type in esm corsair in the search function. I'm on my phone, otherwise I'd link it for you

Sorry, didn't see your comment until now. She's beautiful! You did a great job! Maiden tomorrow, unless I run into any major issues. Should be a great day! Forecast is sunny and 75 with winds ~4-5mph.

Here's the video. Alibis: I had up elevator trim when a lot of down elevator trim was needed for level flight, so it lifted off early...hard to tell, because my cameraman was zoomed in too close...looks a bit more exciting than it should, but BL, lifted off a bit earlier than I normally would. For the landing, little late flare into a slight balloon...good salvage of a bad approach... I used half flaps, but didn't need them with the 5-7mph winds, she's definitely a floater...as you can see, final touch down was lightly on one main and then the other...was still flying well into the rollout.
The middle part is pretty boring...just trimming and feeling her out. The XYZ twin provided more than enough power...she flew well...level flight easily attained with about 1/3 throttle. CG was good...touch nose heavy, the way I like it. I added 44oz of lead to the nose...attached to the firewall and cowling. Left the gear down as I do for all my maidens...one less thing to go wrong. Got a few adjustments to make before the next flight, but VERY happy.

Look forward to the next flight...gear UP this time!

Rooster, what's the all up weight? Congrats on the maiden.

Thanks! I'll have to check, but suspect it's around 26lb.

Thanks, I'd be curious. Mine is close to 27 with the Sierra gear and lots of scale details and full cockpit. I only needed about 20oz in the nose for mine though and it is a bit nose heavy. Ramstein (aka Charles) and I both dolled up our ESM D9s

Strange that hat I had the same issue on my maiden with it needing lots of down elevator and an early T/ O. Makes me wonder if the horizontal stabilizer incidence is a bit down from the factory.

Now im curious! I must be more in the 28lb range, then. I balanced at 145, vice 155...may be why I needed more weight to balance. Didn't feel excessively nose heavy, though.

I think you may be right on the stab incidence...the elevator was dead even when I set the plane up, and then I gave it about 3-5 clicks nose up trim for the maiden. I ended up with my trim near the top of the scale...whole s-ton of nose down trim, and it was pretty close to hands off at lower power settings.

Just got back from a trip, and weighed in today. Not the most precise method...put the nose on a bathroom scale, and tried to just support laterally... All up weight without fuel was right at 26lb. Do you have a pilot figure in yours? That might account for some of the difference...

Rooster,
i have a full size pilot. That adds some, especially since he sits behind the CG. That would require more nose weight.

Your pkane at 26 will fly real nice. Actually quite a floater.

Checks! It was definitely a floater on the maiden!

By the way, did you put a video on YouTube dealing with some elevator flutter?

Ya, that was me. I nearly lost it but was able to land it before it completely came apart. I also posted videos on my working cowl flaps.

Yeah, saw those too. Thought that was a really cool mod!
