Hope someone can shed some wisdom on me . On my ucd 46 my original tank leaked and cracked and I replaced it and it seems that I still have problems . I was using a st 45 and could not get it to stay running with the inverted engine set up . So I just purchased a os 55 AX and that is a great engine figured it was designed for inverted 3 D planes well it ran fine but after 3-4 min it shut off in flight . I ran 2 tank fulls on the ground and it was running great set it rich with a trail of smoke and took off again and again it shut down after 3-4 min running time . I must admit I really hate inverted engine mounting but do to design I kept it that way. Is there any one out there that mounted there engine side ways to me thats the best to have your tank lined up with your engine. I ran 13-4 APC if anyone has pictures of there side mount I would greatly appreciate any advice . Thank you in advance Ken
PS what type and size tanks are you using?
