Ron,
I have been looking for any infomation on the XYZ engines I could find. I came across a supplier in China that has posted on there site comments from customers who have used the XYZ 50. One of the customer posted he is getting 8000RPM with a Xoar 18x8 prop. So it looks like this XYZ 50 engine of yours is going to be the ticket for many a RC Flyer. If you lose on the average of 500RPM for every 2 " you go up in prop size and keep the pitch the same. That means the XYZ 50 should spin a Xoar 22x8 prop very close to 7000RPM. That is very good in my books.
I am now really looking forward in getting my hands on this engine.

RE: XYZ ENGINES
Ya you are right about that, but I am look for only 7000RPM with a Xoar 22x8. The XYZ 50 should be very close to that once broke in. You see I am not a 3d flyer so I am not in the market for those hihg power engines. I fly scale Warbirds so anything that can produce a 1 to 1 flight to power ratio is all I need. My Skyshrk P-40 will weigh around 22lbs so I am only looking for 22lbs of thrust. If you can get an engine for $250.00 that produces 22lbs of thust that is a very good deal.
How much did you EVO 26 cost and how much trust are you getting?

RE: XYZ ENGINES
Guys,
Just a quick note to let you all know that our website is down.
It looks like our ISP did not pay his bill.?><?*(&^$
We payed for a full year up front and that was less than 3 weeks ago ?
Their website is www.digitalcityhosting.com
If I go there it shows me the same screen that I see on my website.?
Just when I was about ready to start getting 6 hours of sleep a night !
Sorry , we will do our best to get it up as soon as possiable.

Ron,
Boy that really s**ks. Just when things start to look better something like this always comes up[&o].
I hope to be testing the XYZ 50 this weekend and I'll post my reading here and e-mail them to you. I will be using a TBM 20x8 & 21x8 prop. I also have a APC sport 20x8 prop I can use. I am sure that on will spin up high, but being a sport props the thrust reading will be lower. I'll keep in touch.

RE: XYZ ENGINES
Ron,
What bolts are the one's for the prop hub? I have 3 black bolts and 6 silver. The black bolts fit the prop hub, but are to short for my TBM 21x8 prop. The silver blots are long enough, but seem to have different threads. I really what to test this engine tomorrow. If the black ones are the one's I must use what size are they so I can go get some lager bolts. The nuts for the muffler would not work. They would not fit inside the slot on the engine for them. The nuts where not the right type. I had some 10x32 nuts and bolts that I used and the muffler is seated on the engine Ok for now.
I really like the way this engine looks.

Ron,
I figured out the bolts that were needed for the prop hub. The silver bolts threads were very tight, but they were the one''s to use. I have all three of the props ready to use now. TBM 20x8 & 21x8 and a APC sport 20x8. I will start with the APC because it will load down the engine less than the TBM props. After a couple of tanks for fuel I will change over to the TBM props.

I for one am Very interested in the performance with those TBM''s, especially the 21x8. I put one on my Brison, and was a bit concerned by the apparent drop in RPM, but it pulls harder than anything else i''ve tried.

I have had to open the 50cc''s now to check and see if it contains
all of the bolts. I spoke to our manufacture about including
all of what we need and no more than we need. Other wise
it can get confusing. I think thats how you spell it.
HA HA !!!

RE: XYZ ENGINES
Mike,
The TBM props are not designed for the optimum RPM''s they are designed to pull and that is what they do. I am using TBM props on my Ulimate 160 with a Fuji 43. RPM''s are down from my Xoar props, but trust is better. I do not have a Xoar prop in the size I want to test with the XYZ-50 so for now I will be using the TBM''s and APC props. I will be order some Xoar props to test with on the engine. I do have cheap chinesse prop called a Volk in a 22x10 size I might try after I have a gallon of fuel thru the engine.

RE: XYZ ENGINES
Well I finally got around to testing my XYZ-50 engine. I ran the engine with factory settings for four 15 minute runs. The engine started very easy each time. I let the engine cool for 15 minutes between each run. I am using a APC 20x8 sport prop for the breakin period. I feel this prop will put less load on the engine with it being brand new. The engine got a top RPM reading at 7200RPM with the APC 20x8 sport prop and a very good idle at 1900RPM. I did lean out the high end needle 1/4 turn.
I had a problem after the engine had been run for an hour. One of the engine supports on the motor mount broke so I had to stop testing the engine at the point.[:@] I will contact Ron at southeastrceingines about it. I am sure he will send out another motor mount.
Over all this is a very nice engine for the money. Not the power of a DA or DL, but it will put out over 22lbs of thrust once broke in. So if you are looking for a nice engine at a good price and don't need more than 22lbs of thrust this my just be what you are looking for.[)]

RE: XYZ ENGINES
Just got off the phone with Ron form Southeastrcengines and he is going to send out a new motor mount flinage as soon as he can. They should be in next week. Ron was very understanding and it looks like these engines need to be mounted to an airframe and broke in there. The engine test stand is too rigid and the vibration just gets absorded into the motor mount. Mounted to an airframe the plane takes most of the vibration and puts much less stress on the motor mount flange. I also was using the wrong size if prop. If you look at the web page the smallest prop I should have used was a 20x10 and not a 20x8. Not that much differance, but it did allow the engine the rev up higher than it should have during the break-in process.
Ron is a great guy and he is still standing behind his engines and is going to send out a new motor flange to me.
Thanks Ron.

RE: XYZ ENGINES
Jim,
Thanks for the input. Great information and could not have said it better myself.
I feel bench testing is good for low rpm running <3000 and to check out the motor for
issues before mounting it in a plane.
I have just about all parts in stock except for a few and the flange is one.
They are on order and should be here the middle of this week.
Will send it out the day I receive my order.
Good luck with the P-40 and let me know how it flys. But thats another forum.

Well,
So far I am loving the XYZ50. For the money it has been a great engine. With each flight it runs a little bit better.

RE: XYZ ENGINES
Gary,
I have a V45 as well. Shakes planes apart because of it's long stroke.
Carb went bad after 1 hour of use but I see that he is now sending
walbro's with them.
We are currently building a device to test BHP and static thrust.
Please check out post #33 for some of the latest testing that I have done.

RE: XYZ ENGINES
During my breakin process I got 7200RPM for a very briff run. The engine started very easy for each run and idled at 1900RPM. I have only 4 fiftheen minute runs on the engine so far. My next Test will be on my plane wirth the XYZ-50 mounted. I will run a Bambula 20x10 and a Xoar 21x8. I will have at least 2 hours of run time on the engine before I take my P-40 to the air.

Hey Gary,
I think that is a great idea.
I really don't want to sell you something that your not going to be happy with.
Read the threads and if I can be of any help, please call me.
I hope to see your order in the future.

RE: XYZ ENGINES
It looks like we will have some very good video of the XYZ-50cc
in a Hanger9 Extra 260 by the end of the week.
We will post the video on here and our website as sson as it is converted.

RE: XYZ ENGINES
I am thinking about ordering one of the 26cc engines. i can't decide between the crrc or the xyz engine. the crrc is $200 delivered and i think they have a little nicer looking muffler. i don't know i'm still looking for some more feedback on these engines. i am going to put it in a 120 size mitsubishi zero. it has a 71" wingspan and i would like it to haul butt across the field pretty good. what do you guy's think?
