T-88 (8 oz. or 1/2 pint kits) costs:Rockler - $12.99A S & S - $12.70Wicks - $12.89Direct from System 3 - $14.00The costs per volume is not a linear relationship so the pint kit doesnot cost twice as much, only a little more, and the quart kit isagain, only a little more. I think if you bought empty bottles, itwould still cost you $10 (ha ha).Robert HainesMurphysboro, Illinois________________________________________________________________________________

Dear friends,I am building the steel tube fuselage Pietenpol Aircamper and plan to use the Continental engine.Does anyone have information that they could share with me that would allow me to calculate the C.G. so that I can know how much I may need to lengthen the steel tube fuselage? Also, any thoughts on the idea of adding X more inches of tubing between station 1&2, 14&13 of the supplemental steel tube drawings, in order to arrive at a proper C.G ( I am thinking 4 to 6 but I would like to do the math first )On the top of a drawing dated 3-8-65 D.P. there are a few C.G. calculations for a 1960 corvair engine Aircamper. It showed a calculated C.G. of 16.85 and said that the C.G should not be in excess of 20' aft of DATUM. What is the "optimum" C.G. measurement for such a craft?I fear that if I build according to plans and use the Continental engine, I may end up having to cast my own Lead spinner in order to balance out.Any thoughts?..........Allen Smith________________________________________________________________________________

One local builder who used a C-85 found it necessaryto move the wing about 4 inches, if my memory is working for once. Thismeant making up a new set of cabanes and front bracing, as the originalsdid not have enough adjustment capacity. Worked out well, though.Owen Davies________________________________________________________________________________
