To Bob, Albert, Tony, ty and all you guys helping us with those great building threads,
Thanks and keep then coming, they really help us become better builders.
Questions:
a) Does the Dr. Pepper bottle develop leaks in the cap?
Do you seal it with?
Does it last as much as a regular tank?
Does it become brittle with time and vibration?
Any worries?
b) I noticed the round hole in the front of the cowl just in front of the carburator is open.
Does it create turbulence problems inside the cowl?
Should it be open or closed?
Does it matter?
Happy Flying
George

Yes I will seal the cap with De Soto PRC 890 B1/2 mill spec tank sealant, also this sealant will be used to scotch the tank to the balsa frames, this stuff cures as a fairly tough rubber that is used to seal leaks in full scale tanks for jet A fuel and gasoline. The tank is 33.8 fluid oz. tank so it will last just a little longer then normal. I don't like the way the hole looks plugged and painted so I am going to place a balsa deflector in the cowl blacked out after the cowl is painted.
