Thanks for the quick replies!
So for the static, I am not surprised I'll have to acquire a couple of feet of plastic tubing, two T-pieces and an elbow, and a static port to fix on the fuselage. Any recommendations or criteria for the location? Prop slipstream would be the main concern, I should think?
Also: after thus improving my installation, should I want to re-calibrate the instruments? Actually, would they have anything to calibrate?
As for the electrics: the battery unfortunately IS under/behind the right hand seat. Placing the relay close to it seems like a very good idea, but would involve quite a bit of work. Think that IF I go for it, I'll also install a receptacle for a high-current plug for an external charger/jump starter. Don't ask me why I want that one!
