    Balance point on mono?

    A good starting point for the cg on a mono is 30% from the transom, around 7 1/4" on a 24" boat.

    Volantex Vector 70 RTR upgrades?

    You are better going to RC Groups Fast Electric Forum for these cheaper end boats as theirs a fair bit on them including various Volantex boats including the Vector 70. One guy has upgraded the Vector 70 with an sss3660-2070kv motor & Hobbywing 90a esc running 4s with X442 getting 46 mph.

    A/A 45 Titanium Rod

    Al on a different note, I understand that Axe Rossi made the A/A motors for you. Just out of interest Axe Rossi seem to have disappeared off the face of the earth. Do you know what has happened to them as a company, im not after any of their products but just curious after them being around for many years. Thanks Martin.

    Engineering's been busy!

    I used to have the forerunner to your Super 11 the Emco V10 P lathe ( great lathe ) for around 21 years ( 1994 - 2015 ) . This was a 1977 machine but had a gear in the headstock explode causing terminal damage inside the headstock ( simply not viable to repair on an old machine with parts so scarce & very expensive if you could find some ). Nowadays I only want something for making smaller parts ie drive dogs, flex stub shafts, couplings etc etc, I am still not sure if I want to chance going with one of the various Chinese made lathes though.

    When you say 0.025" cuts do you mean taking 0.025" off the diameter or radius, in the UK their are still lots of quality made accessories still available for the C5 still made in Austria but I understand these are made by another company for Emco Hobby machines . When I was in hospital in the UK I had 2 ct scans & 1 mri scan, what they found was a blood clot in some tiny blood vessels at the back of my brain that go to the affected eye. Once the clot had cleared both eyes were able to focus together rather than seeing the same object twice ( both eyes were looking at different areas to one another ). Now back to what seems normality im on Statins for life for cholesterol control & blood pressure tablets for life & aspirin a day, not sure if the aspirin will be for life yet.

    Terry I notice you have an Emco Compact 5 lathe along with the Emco Super 11, can I ask your opinion on the little Compact 5. Re its accuracy & general ability on smallish work, do you get much chatter generally from the machine considering that it also uses plain ballraces on the headstock spindle & not taper roller bearings. Its just that I have been offered a like new Compact 5 lathe that I was considering. I to like you had a TIA back in early June 2017 but only spent a week in hospital, mine only affected my vision ( terrible double vision ) & balance to which my vision returned to normal after about 3 weeks. Hope you are progressing with your recovery. Many thanks & regards Martin.

    ? about a two part flex shaft.

    To grease the solid stub shaft you must remove the strut, then remove the prop nut followed by the prop & drive dog. The solid shaft then slides out pushing it out of the front of the strut. As said drill a grease hole in the strut to grease this shaft, but you still have to remove the strut to get the flex out to clean & re grease. Most simply change out the stock 2 piece flex & stub for a 3/16"1 piece welded flex shaft, where you only have to undo the coupling & simply slide out the 1 piece shaft for greasing.

    scuffing or waxing which better faster

    Turn your polished hull upside & wet the hull, the water forms into beads clinging to the hull due to the waters surface tension. Do the same with a scuffed hull & the water runs completely of the hull leaving the hull dry.

    Solder prep?

    Go to Youtube & put in, How to shorten or repair hard motor wires. Dead easy & clean & done in minuets.

    Solder prep?

    Forget messing with any chemicals to remove the coating, many things have be tried before with little effect. Over at OSE forum KFXguy simply used his bench grinder with a wire wheel on, this removed all of the coating very quickly indeed & solder tinned easy. I seem to remember he posted a video of the whole job.
