What engine is shown on 4*60 plans?
 

I have recently ordered a SIG Four Star 60 and was just wondering what engine is shown on the plans.

Not sure what is shown on the plans (mine are in storage right now), but it may be the OS 61FX. I used that on my 4*60 and was very happy with it.

The kit I purchased 4 years ago showed a Saito 65.

Agreed,

OS61FX, that's the recommended engine and will fly it very well. One of our club member has that setup in his 60.

The other great engine for that plane is an OS91 Four Stroke (Surpass) I use that one and turn a 15X6 APC prop and with the stock size tank flying around at half throttle I can stay up 20 minutes. If I shoot touch and goes for the whole tank it's more like 25 minutes. Now please remember my engine is well broken in and on 15/20 Byrons.

Thanks for the info guys

I was personally juggling between using an Irvine 72ABCMKII or OS61FX on the 4*60. But after this experience, it will be the OS61FX.

I have built an LT-40 and it is ready to fly, going for my first lessons next weekend. I did however decide to break in my engine on my LT-40 (OS46AX) this weekend and I was amazed. I have never done this before so off I went, quite nervous, checked that everything was bolted tight, double checked it again, made sure which way to turn the needle to make it rich or lean [&:] fueled her up, hooked up the glow driver, sucked some fuel into the carb, flipped and she burst into life on the first flip :D . Ran through a couple of tanks of fuel using the break-in method in the manual. And now that engine is purring oh so sweet.

This story might not sound so amazing but the last time I started an engine was a Cox .049 on a control line plane and that took a bit longer and went home with painful fingers [:@] So I had my apprehensions about starting brand new glow engine.

I am really really impressed with that engine, thanks OS
