Thank you for the imput I will use the airlons as the plans say.I guess I will use my new 91 GK on this one and maybe my MDS 68 Pro on my Venture that I just can't seem to start.I was just thinking it was overkill with 4 airlons but afer reading your inputs I guess not,which leads to to another ? why do some biplanes have only 2 and seem to fly pretty good?that is what made me think 2 would be alright.
