Default RE: CMPro/Chief/GSP 72.5 Extra 300s Build thread

Did some higeing last night, Tossed out the CA hinges in favor of some heavy-duty Du-Bro nylons. Also picked upi 2 sets of Du-Bro heavy duty control horns for elevator halfs and ailerons, (part 866) and the heavy duty rudder control horn (part 800). I know everyones thinking "build light" but with the motor I finally settled on I should be more than ok as well as grateful for the added security.

I'm ordering the RCS 140 gasser for this bird. should give me all the power I need and then some. After considering the cost of glow fuel at 15.00 a gallon for a 1.80 4 stroke vs gas at 2.50 a gallon I was sold. Also with the more economic gas motor I should be able to get by with a smoke system fairly easily.

Saito FA-180 4-stroke 29.1cc 1.94lbs 2.80hp
RCS RCS 140 Gas 1.4 23cc 2 lbs 2.95hp
RCS RCS 180 Gas 1.8 29cc 3.25lbs 4.00hp


Looking at mounting the wings tonight, I wish they had predrilled the alignment pin holes. It's as if they started to on the wing halves then stopped, and No work on the stab.

Off to work.
