I am relatively new to the electric power arena. I have built 4 of the RC Powers planes and 2 of the RC Foamies plans, plus a 3 plans converted/modifed to choroplast builds. The one constant problem I have is lack of power. I have used a motor available here in Thailand labeled ABC with "0" specs available because they are readily available coupled with no 30% import tax,and the long wait for Turnigy from Hobby King.
I usually end up putting landing gear on them as the usual hand launch has proven most un-successful. Not enough power. End of park flyer!!
As I live out in the boonies everything is mail order, so reliability is a must.
My newest project is an F-16 from Park Flyers International which has a known lack of power on the recommended a 6x4 prop and 2217-2200kv motor.
Has any one got a better motor-prop combination for the park Flyer? I think this plan will need all the power it can get.
Keep everything you have and scale your plans down 15%. Only real change is prop slot. It'll do the trick to keep you on your toes!!!chas
