Booma 1200MA MAXPACKS for 50cc?

[Alexander Cui]

Hi,all.I purchased a 29% Extra 260 (SD?) from a model manufacturer here China about 4 monthes ago.It's setup is:
1/Engine:3w55i with Zinger 22*10 prop(6700rpm,ground),
2/Servos:BLS352*2(aileron),9154*1(rudder),Hitec5645M G*2(elevator),HItec5625*1(throttle),Hetec125MG*1(c ab.choke),
3/In flight power system:smart fly's power expander pro and optic ignition cutoff system.battery packs:2 sets of 5s1600 ni-cd(sanyo rc4/5 sc),
My question:Would this plane become an aerobatic plane or a bomber with this set up for the plane's full weight is 8.3kg(18.4lb.),wing load is 92g/ sq dm (0.21oz/sq inch). Bbattery packs 's weight is about 480g(16.9oz), if I switch to Booma's 1200MA MAXPACKS the plane's full weight would be 8070g(17.8lb).I dont want to get rid rid of power extander and optic ignition cutoff switch for the reason of security,the total weight of them is only 80g(2.82oz).By the way,I place an order on Booma-rc's webshop on 11/23.I found that the shipping information was "Pending" yet this morning.I cant get Booma rc's any response about the order.Any help would be appreciated.I wrote this thread for a whole morning under the help of a dictionary for my English is poor,so be kind to me please.Cui

You may have a problem getting hold of Booma-rc today, and in fact for the next couple of days, Rick is at the ASAA championships for the weekend, first day of contest today. I am sure if he is able to check he will get back to you, if not I am sure he will be in touch within a few days.
