John M Oshust | AerodromeRC PT Crop Duster | Parked | 14-Jan-10 11:39 | | Views : 1642 | I remembered that polyspan will shink even afeter it is painted. A few minutes with the heat gun and the fuse and wings are tight again. Shrinking after paint makes the paint a tad glossier. Of course you must heat slowly so as not to damage the paint. Off to the cabin tomorrow!! |
John M Oshust | AerodromeRC PT Crop Duster | Parked | 14-Jan-10 11:36 | | Views : 1567 | Remember Schnazola the crop duster? It was in the shop for a pre transport dusting and inspection. It has been about 6 months since its completion. I noticed that the balsa must have dried and the entire plane has shunk a bit. The music wire rigging was bowed and the polyspan had sagged. I cut small sections from the wires and installed Al tubing ferrules, crimped on one end. The rigging is straight again and the ferrule should allow for linear change with temp. |
