So how did your plane fly? Looks like a nice plane. Did the chines work well? I did the same chines as acer did which are considerably bigger but his seemed to fly fine. Have you seen that thread? Well I think I pretty much got rid of the upthrust had to take some angle out of the engine mount anyhow so should be good to go. Ailerons came out pretty well for a first time builder Sure is different working with balsa as opposed to carbon fiber!!! Clint
