Full-fledged modification

Extended moving wing on the main wing of "Begin the Begin" , a famous Golden age free flight model does not take effect as the aileron enough to make rolling maneuver, so I made up mind to modify it regularly, cutting some adequate area and setting the aileron as normal one has.
Dihedral angle has remade as zero degree prior, it's possible to gain the datum about the designing of aileron area. Probably, normal effect would be obtained as a matter of fact. This is because the forward movement of lift center of gravity occurs.
After this trial experiment, this B&B model would be modified to change the vertical main wing position as the low wing model by penetrating 18 mm aluminum pipe for setting the main wing of  "Sky Leaf", to know the effect of the main wing thrusting position. Much datum I wanna know would be recorded after this trial.
The power source burdened for this model airplane is OS 40 FSR with nose 50 gr weight, I might consider about some replacement, into more heavier one such as OS 46 FX obtained by chance the other day or ENYA 45 CX also obtained in Yahoo Auction at very low price, both of them has stout crank case construction leading to stable and powerful operation.
If B&B model could accept the main wing displacement, the coating film design and the shape of the main wing chip would be changed and remade.
Let's see what will happen soon.
