Funtana X100 Electric Conversion

Well, after few months of waiting for all the parts etc to arrive and after unsuccessfull maiden (long story of stupidity) , I was able to test fly the Funtana this weekend for the first time, all I can say is.. WOW.. totally over powered but SOOOO much fun ;-).

Current setup:

Motor: NNB A5330-9 260kv, 

Prop: XYH/EMP 17x8 E

Battery: 9s Revo 3300mah.

ESC: 100A HV Hobbywing version 3.1.

Servo's: Ino-lab D761MG all round except on rudder which is a D751MG

Receiver pack: A123 1100mah 2s.

Receiver, AR7000 Spektrum

Current power: 1800-1600W, depending on battery charge. Peak amp about 55A. Eagle tree flight at bottom of page.

Flying time: 7 min, using about 2500mah, so should be able to get 8-9 min. 

 

Hope to test the A123 batteries next time around, have 10s pack here which should give same power and about 5 min flying time. but much faster recharge times.

 

Rest of aircraft is standard, only modified firewall to allow more air movement between fusalage and cowl area. Also need to decide still where to cut cooling holes. I'm flying with no cooling air exit holes at the moment and air temp seemed to have increased by 2 Degree's C, which is not to bad, but there is definetly a high presure forming in the cowl (measured with altimeter)so need to find nice place to cut few small exit holes.

 

Pictures below of engine mount and engine with extra back bearing to help the normal X mount cope with 3D Gyro forces. Maybe not needed, but you can never have enough support ;-)

Picture before first maiden. Still have test wooden prop on, which gave to much power (2500W). HYX 17x8 now produce about 1800W and still to much.
