Can someone please point me in the right direction toward a modern gas engine for the Solution 70”, that will be able to hover the plane?

Also a decent target all up weight. I’ve got some really good contest balsa that I’ll be using. I can usually build quite light. Cannot see anything on the plans regarding weight.

Oh and I’m new to gas and it’ll have to be able to be silenced to pass a noise test from both sides, head on and from behind at 7 metres. 82 decibels. Thanks.
