sure-I used the servos as called for, one 8411 and 9411's and a 9 ch JR PCM rx
Idid use a smaller throttle servo
pull pull using supplied cable and ferrules for rudder .
Saito 100 older one smaller muffler . no spinner
cut out entire bottom of cowl and trimmed wood floor back to ply edges on canopy - very little weight saved there but I want full access to engine and I like to see into the fuselage
The batt is extremely light exactly 4 ozs I just rechecked it with the APC 15x6 prop - 8 lbs 2 ozs -
No SFGs in this weight . balance may go further aft after flying -I will move batt from engine and shift as needed.
