larry,
I think the most advantagious mod would be to loose the kit supplied wheels and get some dubro inflatables. Fill them about half way and it will stick to the ground once you touch down. The plane is pretty heavy, with the supplied tires it will want to really bunny hop. If I had got another one I would defiantley go too a gasser with it. Your 1.50 will fly it ok but, you'll quickly get tired of buying a lot of fuel for it, at least I would. I had a OS 1.60 2 strk and it was perfect for power in my opinion. That was before I switched over to gassers only. For me taking the wings and rigging off of it all the time got real tiresome. I did every 3 or 4 flights just to make sure everything inside stayed in place and was holding up. I left it together for transport and it was hung by a sling for storage. Just ny .02
