Yeah my Dad already has it. Showed it some guys at the flying field and it drew some interest. It is going in a Senior Telemaster, so it should work great.

SV 17cc Engine

Just purchased an SV 17cc engine,new in the box ,from the outside everything was fine till I started to take a closer look at the prop shaft, what I found was that the crank /shaft threads had been double cut damaging the treads, second thing I found was that the cylinder head foundation bolt hole castings were not formed correctly, next I removed the aft portion that supports the crank shaft, aft portion of the crank shaft had grinding marks and high heat marks.
From the outside it does not look bad, but what is inside is nothing but JUNK, buyers beware.

SV 17cc is underpowered for the RV-4 to much weight (13#)
it took off but I landed after a round because I was afraid to crash it .... not enough lift it was difficult to maintain it in the air… don’t try this engine in a RV-4 25%
I’m flying my RV-4 with a CRRC 26cc … a lot of power it fly whit authority now
I will be using the 17cc in a ugly stick 60 size … I wish to have fun with it

Dad of five, love to fly!
I am putting my SV 17 into an old Hanger 9 PTS Mustang, It was crashed last yr so I had to rebuild the firewall anyway. I moved the firewall back 1 inch and built up the nose so the cowl would still fit. I had to put both ingnition and radio batts in the tail section to get the CG right. the ignition module is right on the CG and the fuel tank is up in the front where it originally was. There is not much left of the cowl, I had to cut most of the bottom half out to fit the carb on one side, the muffler on the other (borrowed a smaller stock DLE 20 muffler- fit with some mods) and the head on the bottom. should be ready for maiden this weekend. If anyone is interested let me know and I'll post some video on youtube. Roger

These engines are awful until they break in which takes some time. Biggest improvement is going to 50-1 mixture. Smooths out noticeably and RPM at WOT stabilizes. Others running successfully at between 50-1 and 100-1. Black oil blowing out exhaust reduces significantly.

New situation this AM was carb ice visible when running up on starting bench at field. OAT was 64 deg. with NW wind and low overcast. Not sure what to do about this, but probably isolated incident and not likely to occur again.

I have one of these engines and cannot for the life of me to get it to run right. I have been all over the map with the high and low needles and cannot get it dialed in. I have many years experience with r/c gas engines so please don't start a lecture about how to tune it.
I suspect the timing is way off but have no way to really change it as the Excel ignition is auto advance.
A guy at Troybuilt told me they got a bunch of these in with the timing wrong and had to drill new holes to move the sensor. He didn't have any details, however. I need to know which way it is off....too far retarded or too far advanced. What she the timing be. that is, center of magnet at TDC to center of sensor.
