My plan arrive today, very nice, but there is no mention of wash out in the wings. I have found that all my scale war birds ( Spitfire and a ME109) require some, any any comment. Also as I wish to use only 4 cell lipos, I'm looking at reducing the span to a maximum of 54 inches, any comments on the appropriate motor would be useful, all my motors come from the Hobbycity site as buying from the UK here in Australia is too expensive Regrds Stuart
