Hi Foodstick. Never heard the term 'Dial a crash' with the Optic 6 😆. Although I didn't use it for long it never had an issue. Even with the bodged together battery system. The freq module was taken from the Eclipse 7 as it was inter changeable with the two units but works on 36Mhz. Can't beat a long wire transmitter 😁. However since the arrival of the Spektrum the only evidence from days of old is the hole in the tail there the Rx wire used to run.
Small progress with the Cub as this winter maintenance lark continues at the dairy plant. Only a couple of weeks 🤞to go, then I can get back to retirement. Which I miss dearly 😁. Have finished up the engine mounting setup.Hangs on with 4 screws up through the bottom which also clamps the inside and outside landing gear plate together....Also managed to get the front wing mount made and installed.Found a great source of 5-ply for nix. Cable rolls use it for the ends, Of course it's about the same quality as pallet wood, but fine for models 😊.Slow progress, but still progress none the less.
The last flight I had with the Dominator showed a resonance with the engine at idle. I'd heard it before in the past on other engines and something told me it was one of those 'Bad' noises 😳. After a flight I hit the engine cutoff switch and the engine stopped....Instantly. Turning the prop slowly by hand showed a jam up internally. Sure enough when I took the engine apart, the cause became obvious....Yep, one of the balls had broken. Fortunately the bearing still had the shield on so the broken bit was contained. It was a fairly new bearing as the original had done the same thing, only that time the broken bits went up through the cylinder causing all the usual carnage on the way. Including gouging a line up the side of the cylinder. But it still had compression...sort of...so I fitted new bearings to the old ASP46. Didn't notice the cylinder damage until the new ones were being fitted 🙄. But it ran well. Another new bearing has been fitted and it runs fine, but haven't had a chance to air test it due to work and weather. But not long now 🤞😁.
Cheers
