Anyone built one of these models? I have a couple of questions before my son and I start to build one. We are going to fit the OS91 VRDF engine with a RAMTEC fan unit. The instructions say that this engine will fit 'with slight modifications' but doesn't say what they are? Has anyone built one with this engine? If so what mods are needed? What's the noise output of this combination likely to be? We fly from a site which has an 82Db noise restriction. Are we likely to achieve this?
TIA
cheers, Len
