I am Bob, a Sonerai admirer since the 80s. I purchased a set of plans and wing kit. That was about the time that Monnet was in business with the Lotus folks. Ultimately when production stopped, I sold my wing kit. I always hoped the Sonerai would come back. Finally it has. My question: Has anybody increased the range beside the tank behind the back seat? It seems possible to add a front seat tank when flying solo. Just trying to get 500 mi. legs. Another question: Are matched hole drilled skins available? That would make life easier. Thanks
