Jim, now I have to get cracking on my CG Sukhoi. I have mounted the SPE 26cc gasser and have just a little more work and I'll be ready to provide info on that engine too. R

Rob,
I am sure you'll get very close to 7000RPM with that prop once a few more tanks have been run thru the engine. I have a Brillelli 46GT and I am getting 7100RPM with a Xoar 21x8 prop. My Brillelli 46GT has a Walbro 201 carb. That is the same carb a DA-50 use's. Do you know what Walbro carb is on the XYZ 50. If it is not a 13.4 mm carb like the Walbro 201 you my be down a little in RPM.

I'll be getting my XYZ 50 this Friday and I'll take the carb off and take a look. The # on the Walbro carb is very small and hard to read. Sometimes I have to put the carb under a magnifying glass just to read the #. If the carb is a 12.7 or 13.4mm carb it should be OK. Anything smaller and you will be down is RPM's. I had a SPE 40 and it was running a little rough. Just could'nt get it to run right. I ordered and Walbro 201 carb from Brillelli and that not only made the engine run better, my RPM's jumped 500RPM's. The SPE 40 had a 11.1mm carb on it.

Sounds very smooth. I think you got a winner. My friend just called me and said that the SV50 didn't even have a cylinder sleeve. Now I have to wonder about my SV26, which by the way just got a new mounting plate. I like the words heavy duty... lol

Well, you guys have convinced me to stay away from the SV engines. I sorry that you have had such bad luck with them. I was looking at the Hobby city webpage and it looks like they have some new products. R

A couple of months ago, Hobby City was supposed to send Greg and I new rear crankcases for my SV26, and his SV50. They finally showed up today, but instead of gaskets to put the engines back together with, they sent us two micro digital servo's. What a hoot ! I want some of what those folks are smoking ! I used to be disgusted, but now im just amused. Small, thin walled gaskets are no fun to make, but it looks like we have no choice. Hobby City has the worst customer service I have ever experienced, and I will never buy from them again. Now for the good news.... The new Stearman is finally ready for it's maiden flight.
