Heya, i just bought the extra 300s 140 arf'72.5" from jamara 2 weeks ago ( was 212 € in Belgium ) realy a good price/quality compared with other arf's of the same wingspan. Last weekend i flew with it & its a great plane.
I've got a Saito 180 ( 20% coolpower ) on it with a 16x8 apc prop, a little overpowered in that configuration. While flyin acro i noticed that with slow speed & pullin the elevator quickly the aircraft tends to roll to the right. But its rly great flyin with, on the first flight i did knife edge .4 rols snaprols inverted flight & it behaves well.
The only thing I changed is the rudder servo, I've put the dubro system with cables into the fuselage because i thought the point of gravity wouldn't be ok but after finishing the model the cg was way in front. So now my battery pack ( receiver ) is located half way back to the tail for compensation CG.
Quality of the airplane is ok, just the red line on the wing ( oracover ) came loose after the second flight a little ironing fixed it.
