Hi Flyboy. I have been flying mine for a couple of years now. I use the Rimfire 400 because the plane was designed that motor. You can make the Eflite 450 work but the cowl may not fit correctly. I have the Eflite 450 motors but I don't understand what you mean by "stock prop".
Try the WW1 section at the bottom of the first group of threads Lots of WW1 info there. I just built an ARF Spadx111 and used motor,esc,batts etc from headsuprc in Fla lots of guys get their stuff from him. He has engine set ups on his site as well as you can email him and he will suggest ideas for you.
Tell Jeff at HeadsupR/C what you are going to build and he will recommend a motor, esc and battery combo for this airplane that will give good performance and you'll spend far less then what Great Planes would like to sell you.
Yea. I have a park 350, 480 and power 10 I can use. Just wondering if one of those will work.
I will be spending all my cash getting this one. :| So If I do not have to buy anything else I can fly sooner! Remember at my age money dose not come around often. :\
I did a search for Park 350 on Horizon, they do not list it. On the Rimfire 400 the recommended prop is a 10x4.5 On my Eflite Motors I use a 10x7 slo flite prop. You can try the 10x4.5 on the Park 450. Good Luck
