Simon described the physics well. As it is a converted model you may have put the undercarriage too far forward, try moving it back incrementally.

Multiplex FunCub wheels. Due in next month here: https://wheelspinmodels.co.uk/i/multiplex-ul-wheels-120mm-x-26mm-pr-733198-194414/ but you can shop around.

I’ve just realised that you are probably referring to the DC/Albion 0.15cc diesel. That I don’t know.

Assuming you mean the full size I think it was VW powered & can’t remember if it was a Turbulent or Taylor Monoplane. I’ll have a look next week when back from holiday if no one else responds.

The Futaba Corporation is pretty substantial with the latest results just published showing net assets of about 90 billion yen https://www.futaba.co.jp/en

There is a strong yaw/roll coupling with these models & I find I need a touch of opposite aileron to keep things tidy in the stall turn.

It is in CAP 658, Chapter 5 Paragraph 1. However the CAA withdrew CAP 658 following the introduction of their competency requirements. I’m not aware that the specific requirements were carried forward but they remain best practice.

The same thing happened with the Kyosho CAP 232 a few decades past & I never found a cure. Just had to accept it was a characteristic of the wing platform, live with it & fly around it.

This is an example of Apple translation in action. And a very useful phrase it is Shaun🤣

Likewise Apple devices have a built in translator

Well it might be. Let me give you an analogy. Someone planning to visit the UK poses this question on a forum: ‘What is a safe speed to drive in England?’ There follows 5 pages discussing limits, weather, age experience, training, traffic, light, road surfaces, caravans, lorries, schools, villages, motorways etc etc. The OP comes back with ‘Yes, yes but I just want a simple single speed to remember that I can drive at.’ To which there is a response of 42mph that is just as valid, useless & dangerous as any other number. Back to IR. You might not need to know ‘life universe & everything’ (another reference to the late Douglas Adams) but you do need the many variables discussed in this & the earlier thread to have a meaningful answer. These will include, but are not limited to: Size, shape & chemistry of the cells. Their internal & external temperature. Their voltage and state of charge. Whether they are being charged (and at what rate), discharged (ditto) or resting. The resistance of the leads & connectors. The method of measuring. The calibration of measuring equipment. The use the battery is to be put to. And your definition of ‘acceptable’. Once you have nailed down each and every one of these you might come up with a number, but until then both 14.9999 & 42 are equally as valid, and equally useless.

It's very simple. The answer is: 42

15% is what they need 😀

I'm with Nigel. I built a Magnatilla in 1983 - I can date it as it was my first build after moving house - and covered it in Solartex which had just come out. I never fuel proofed it as it said it was not needed and it flew for many years, in fact it got through 2 engines, without any problems. GlossTex was introduced a few years later and has a quite different & distinctive appearance. My last kit built Wot4 (I've built 4 over the decades) is covered in GlossTex and is now about 30 years old, albeit I retired it 12 years ago when I went all electric.
