Hi!
I'am assembling a Vmar Spitfire and I would appreciate some advice!

- I'm using an inverted .52 4-stroke Magnum XL engine and I wonder how much of the cowl I should remove? I understand I have to remove at least some to clear the engine, but is it enough if the main part of the engine is clear and the silencer, or do I need to make an air intake below the spinner and/or a rear ventilation "hole" where the cowl meets the fuselage?

- As the engine is mounted inverted, should it be positioned level with the engine thrust line or should it be positioned above it (and the tank) to avoid flooding?

- Are there any specific things to think about when time comes for the first flight?

Thanks in prehand!

By the way, where and how can I attach the cowl to the fuselage?
