Lessons Learned from Bath Tub Run - Current Measurements
A few items that really bothered me during the Current Measurements while the model was in the Bath Tub. Ordinarily, one does not see the actual workings of the Power System while it is in water since the model is covered and moving away from you. Well, last night I had the opportunity to really watch and hear the power system and concluded the following:
1. The "No-Name" gearbox had to go since spare parts just could not be found and because the Gearbox Spur Gear was really worn and it vibrated the entire assembly at moderate speeds and including high RPMs.
2. I looked all over my hobby drawers and found a brand new Airplane Gearbox known as the Electrifly (Great Planes) GD-600 and I believe it is the 2.5:1 ratio.
3. The Rudder travel was fixed as reported earlier using a new Rudder Servo Arm and located the push rod assembly at a farther hole and that did the trick.
