Hi Andy I have been working on a barn find old Sea Queen kit in very poor condition. The restoration required fitting a 5mm prop shaft as the old shaft supplied was a little short, I ordered a new 5mm shaft 19inches long from Model Boat Bits uk and when I tried to fit it it would not fit. Not realising the old shaft was 3/16inch. I had to ream the bushes to take the new shaft of 5mm. this proved a little difficult as the shaft was already fitted. I finally did it and everything works as expected. Fitting the motor which is a 700 ?. The shaft was 1/4 inch diameter. Boring out the brass insert did not leave much meat and I am hoping it does does not let go under power. So far so good. I hope there is some info there that you can use. Regards Sid
Hi The Formula for charging any battery, Gel cell or NiCad is Divide the amps (milliamps) by 16. This gives the charge rate in Milliamps. The charging time is 14 to 16 hours. With this formula you cannot overcharge the battery. EG (1700 milliamps divided by 16 equals 106.25 milliamps. The approximate charge rate for 14 to 16 hours)😎
Thank You for your response. I have seen the gear set on line but I need the complete unit. The model I have built is designed to take the MinI Olympus unit and I have fitted an old one with problems. I did not realize that they were so hard to find. I may have to redesign the mounting to take another gearbox.
