Help!
89" slipstream yak 54 - 50cc electric 3d plane

I Have a 89" Electric Yak 54 with a Neu Motor (1524/1.5y) with gear box swinging a 24" Xoar Prop..CC Phoenix Ice 120HV...
Need advise..
1. i only have 5s' 5000mah packs...previous owner used 6s packs and he said with this Motor it had lot's of power,,even to climb comfortable out of a hoover...i have not flown plane yet...Just got my esc and servos...but i am out of money and only have 5s 5000mah 30c packs....
so is it possible to Fly this big plane on a 10s? All i'm going to be doing is basic Aerobatic..No hoovering off Runway...No no...not for me just yet...but i will be doing Loops,,Rolling Harriers...you know,,,your basic Maneuvers.
so is it possible to use a 10s setup and be comfortable?

2. i have Hitec 7954Sh in both Elevator Stabs which are over 300oz of Torque but my Rudder is only a Hitec 5625Mg and my Wings are only a Futaba S9204,,,
So i know the Elevator servos are good but can i trust S9204 in my Wings? and can i trust the 5625mg for the Rudder?
i don't have a lot of money to spend on Electronics but i have decent electrics i believe..just want to get a 2nd opinion...
All this is for basic Flying...Loops, Rolling Harriers..Nothing really special..i may give it a Snap of 3d every now and then...
so please give me your advice please...i would like to hear..

Did she fly yet? Do you know how much she weighs with the 5s packs in? Slipstream builds a very light airframe. I would be very surprised if 10s couldn't pull it around the pattern as long as the motor can deal with 10s. What does the motor specs say about lipo cell # range?

I'm just about done..as far as weight..i haven't weight it but i imagine i'm in between 16 to 18lbs.
I'm using 10s 6000mah packs...when i spooled it up with that Large 24x12,,it seems like it had decent pull. on 10s it will probably fly like a pattern Ship....Slow 3d but on 12s i think it will Rip thru the skies..Motor calls for 12s...i think i'm going to change the 2 Ail Servos and Rud and put Power HD 9150 in all 3....those servos have over 200oz of Torque....that seems more safe to fly....
