Rounded or squared whichever looks best to you. There's no aerodynamic benefit either way.

So far only HoLEP has been mentioned by the urologist but as far as I can see it's no more invasive than Urolift. My bedtime activities are limited to walking to the loo several times each night poking Mr Dribles in the eye with a plastic tube waiting 'till the tears stop then making the return journey back to bed. 😒 Good luck with whichever procedure you choose 👍

Thanks Ian, David & Martian for the info & good wishes. Martian, the HoLEP op involves passing a telescope (Not James Webb proportions I hope !!) through the urethra & using laser fibre to do the "re-bore" then chop up & remove some more bits of the prostate. So it's front door entry not back door like your neighbour. In the mean time I've received a 4 month action plan starting tomorrow with a review by telephone then some more tests etc finaly to be offered to be added to the waiting list for HoLEP. If the opportunity arises I'll ask to be put on the list before the 4 months is up. Any further info will be gratefully received, Pat.

Thanks for the reply BiB. I should have mentioned HoLEP isn't a cancer treatment it's basically a "rebore" of the urethra (pee pipe) using laser to clear obstructions . About 5 weeks ago Mr Dribbles elevated his prolonged industrial lethargy from go slow to all out strike, necessitating in a trip to A &E where I was fitted up with a semi permanent catheter with accessories. This has since been changed to a more discreet but in some respects less convenient DIY, disposable one shot catheters plus the return to nightly sleep walking comfort breaks routine. Before I commit to a HoLEP operation I would like to hear the pros & cons from anyone else's experience of the procedure or alternative procedures.

Has anyone any experience of Holmium Laser Enucleation of the Prostate (HoLEP) ? I am to be offered entry onto a waiting list for this procedure in the next month or so & would like to know as much about the pros & cons of the options available if I agree to go ahead with the operation. Also would like to know how much long term real life benefit & detriment (if any) experienced after the procedure. Thanks in advance for any info.

Nah, there's no "dog" collar. 😜

For the same reason that life-time diseases of the past aren't around anymore, infant mortality rates have dropped to a fraction of what they were & this post is being read by a much older demograph than would have ben possible in the good old days. 😉

Ditto.

We had to take tablets to get rid of the worms 'cause they were eating us. 😟

Must get lonely flying lonely your own, Phil ! 😁

I have a copy of the original Ben Buckle catalogue, it's definitely not a Southerner Major. As jeff2wings posted it seems to be an enlarged version of the KK Bandit. The wing root LE cut-away & tailplane position on the fuselage fuselage are identity give-aways.

Are you referring to the engine in the polyhedral winged vintage model ? There's a photo of an OS20FS in the post of 10.36 Monday.

Telemetry ?

That's because it goes with the Tiger Major as Sussex mentions. 🙄

The speed of series wound motors is roughly inversely proportional to the current, if they are run with little or no load they can reach dangerously high speeds. Typical damage would be the commutator disintegrating then the debris flying from it. These motors were (are ?) normally solidly connected to their load, never belt driven. Ref my 60 year old copy of Electrical Technology by Edward Hughes & my memory. If only I could as easily recall where I last left my specs. 🙄

OK, I missed the minimum prop size question but answered it anyway and addressed the follow on question by using an extreme example to point out the obvious impracticlity that could result

No they won't, the larger motor will run faster & take more current. See Mike Blandford's reply above. What point about minimum prop was made ? Where has a "motor's structural "burst" rpm" ever been specified ? As far as the motor's concerned there is no minimum size prop but you won't get far powering, for example, a Wot 4 with a 4" prop. All of our brushless motors can be safely run without a prop. We don't use series wound motors. Most of our brushless motors are "Delta" wound a few are "Star" (AKA "Y") wound. From the electrical POV there really isn't such a thing as specific voltage limitation but it wouldn't be practical to use a voltage that can only drive an impractical size prop within the current limit of the motor.

I've attached a couple of guides for beginners in pdf format that you may find helpful. There's more in each than you really need. If you have the "Quickstart" spring & finger mangler I'd advise not to fit them as they're more of a liability than help. Operating a First Diesel.pdf Quickstart_instructions.pdf

I forgot to mention in my previous pot to add a drop of washing up liquid to the water. This reduces the surface tension & allows the water to soak in deeper.

Sorry Matty, that's not correct. There is no absolute max power for a motor, however there is a max current it can take. Since power is the product of voltage & current the max power can only be stated with reference to the voltage that is being supplied. The max current that a motor can take is subject the length of time it's applied, how well it's cooled etc. The voltage will be limited to the practicality of the prop size at the motor's kv.

The motor is really only a power converter. The power it extracts from the battery is basically governed by the size of the magnets & the weight of copper in the windings. In practice you can estimate a motor's power output from any given battery by it's total weight. To a lesser extent there are some design features that effect the mechanical & electrical efficiency but these generally result in diminishing returns relative to cost.

One possible side effect of the Welsh 20mph restriction that hasn't been mentioned is that it may encourage more drivers to use "rat runs" through quiet residential areas. The speed limit will be the same as the "official" route, the distance will often be shorter, the only real disincentive might be traffic calming measures like speed bumps etc.

There are not many towns where a delivery vehicle can drive at 30mph the whole of the 30mph limited route, in fact they may not even be able to do 20mph for parts. In practice it's sometimes the case that a restriction on top permissible speed results in higher average speeds for the general traffic flow.

Prick the area with a thickish pin, squeeze a wet cloth on the dented area - the idea is to get the water into the pin holes. Now go over the area with a hot covering iron or household smoothing iron. The iron should be hot enough to turn the water to steam. The hot steam & pressure created will cause the crushed Elapor to expand from within.

Doesn't your second sentence example contradict the first example ? 🤔
