OK....JUST GOT MY P-47---

I have 2 questions I need help with
#1) I have a Park 400 outrunner in my Spare parts box (not 450)...it is one of the rec. setups...the lightweight setup I believe. Now With this motor will I have More power than the stock Brushed 480?...I know its a lot lighter and Not sure about the Difference in power...anyone used Both let me know...or if you just used the 400 does it Fly well?
#2) This is my First Plane with Wings down low. I have a few Slow sticks...A converted aerobird extreme ( standard elec. 15-3 burshless)...I am into Aerial Photography Big time and these 2 planes are doing me well. I fly them Both Perfect and can do many tricks and stunts ( well as many as you can do without airleron)...So This is The plane I decided to get to allow me to do barrel rolls, Flipping sideways..LOL...all that stuff....So...TO THE QUESTION.....Being my first plane thats NOT with the wings up top....Is there anything I should keep in mind or do differently with the different Type of flyer?....
I plan on waking tomorrow and bring the rest of the house awake with the smell of Foam safe CA glue early in the Morning...
This plane is a VERY Cool looking plane...I saw it at Hobbytown and fell in love...for the price I thought it was a great deal....OK Guys....Any help will be greatly appreciated and Happy Holidays to all....and to all a goodnight.
