Try a secondary bellcrank, to transfer the push/pull. Be aware you will need a spring to pull the throttle shut, or open, as the more complicated system also has more slop in it, and slop is not good at tickover. If you are not familiar with secondary cranks, look at the throttle system in small outboards, same thing.

Erf, they know their tools, and temperatures. And xx hours a week, good quality control, piece rates. You get skilled, or leave.

We cover the odd model. They do years of output before mid morning tea.

So when do we see some engines back in stock?

Just to make sure you know you are back in work.

Actually, that looks like ladies feet.

Read the thread title, thought it was a thread on driverless cars. I reckon my current stead will last until they come along for my dotage. Wouldn't fancy building one though

Thread: BMFA subs increase.

KC, do I detect a little antipathy towards the BMFA.

A prop, and postage, less than a pound. Try making that prop, and eating. Not here please.

Thread: What is the cause of this?
14/09/2018 16:06:28

We are complicating this. In theory. As BEB says, do the flying tests. Establish the problem.

14/09/2018 15:17:12


The position of a balance point is not written in stone, the instructions generally give a safe position, not the best position. It's very likely PatMc is spot on, a too far forward, but safe manufacturers position, giving a climb under power. Move balance back, the climb disappears.

But bottom line is, try the tests given above, no point in debating it until you establish what is wrong.

Edit. A nose heavy plane does resist the nose coming up. That's why you need some up trim to keep it up. And the up trim gets more uppy when the power comes on, or it increases speed because of there is more wind, and force acting on the elevator

Thread: BMFA subs increase.
14/09/2018 12:41:12

I think the concept of worrying about a plane hitting a car parked behind the pits is strange. In my twisted logic if I am standing behind the pits, even by one centimetre, I don't have to worry about injury. That is someone else's task to keep me safe. Planes don't reach the pits.

If you can't fly to this standard, don't fly, unsupervised. If you plane does the mythical lost signal, sort out a failsafe to bring it down quicker.

If your insurance costs are up because cars and models are being hit in safe areas, you are on the waiting list to kill someone.

Isn't the "A" achievement scheme about demonstrating a robust theoretical and practical knowledge of safety on a standard club field..

Not tooo sure, I'm not a member of any organisation mentioned in this thread. And reading the thread I am not getting much sense of what you are talking about. What I get is a take on the old phrase, "don't let a fact get in the way of an opinion" Not educating or amusing.

Thread: Boddington Instructor Plan
10/09/2018 20:31:40

Thank you DeeBee. Answers a few questions, above. And, a trainer plan, and a Boddo job, for a 40 is more difficult to pin down that expected. A Boddo plan generally flies just fine.

Edit, having built it, that is.

Deebee1, what size is your plan?

Haven't watched the program. Enjoying the thread.

Geoff, there was a nice model of a Laser this week, full sail suit, no radio. I know this model is a popular one class design.

Well that's arguable Don. It's down to your perception of what constitutes relaxation or enjoyment. Some folk dangle little hooks in rivers to catch fish, others whack little white balls all over big mown areas, some breed budgies or collect stamps.......

It may not be interesting to you but...............

I agree, and while I don't do any of the above, have to confess an interest in the evolution of flatfish. Which is a minority interest you would agree. But my point was I think you will find it boring. Like swapping a motorbike for a pedal moped for a Sunday cruise to impress the young ladies.

Mate of mine used to be a solicitor specialising in conveyancing. He met a bloke, on a cruise, with a sharp sense of humour, a senior actuary, who observed that juniors, were advised, if death was too exiting, conveyancing was an option.

Perhaps, in our case a boat would do. A sailing boat would be exempted, but a little motor boat would bore you after one circuit. You would be praying for the battery to go flat. Trust me.
