 Not sure  we get don't much anymore but if you read the papers I think it's called 'seasonal disruption' ??

Beautiful build....and who doesn't like yellow!?  Hopefully some inflight videos?

 I managed to get out to day a try a few test glides with Piper.


 I couldn't get it go at all with the huge prop on and a small number of turns pulled it into the ground. I removed the prop and rebalanced the model and it has a nice glide. I think on that basis I'll reduce the downthrust and reduce the prop size a bit

[OZPAF]

That looks nice Chris. Great way to spend some time - it loooks calm and quiet and plenty of open area.

Thanks John


Back on the bench I rebalanced the model with the prop and motor added. It needed just a tiny bit of tail weight to achieve the 40% MAC CG that worked on the glide. The prop has been cut down from 15" to 12.5" so lets see how I get on with that 

Ofcourse it's raining again now

Today I finally maidened the Piper on Port Meadow.

In rather senior moment I discovered only when I got there that I hadn't actually made a fitting for my stooge to fit the bulky fuselage !!! I had to resort to hand turns only but it's looking good and like it's going to go well on full power after some thrust line adjustments.

There a video here though you have endure the FF Tomboy and Tom Thumb as well

[AndyB]

That looks as though it'll go quite well.

Easy syarting diesels and a successful maiden of a rubber model on a sunny day - what could be better.

Another entertaining early morning video - thanks Chris.

What a great combination - Tomboy and Mills and without much wind!

The Cruiser looks a very promising performer on it's new prop. incidentally how large was the initial prop - the cut down version looks close to 45% of the wing span. With enough rubber and turns that could be a very fast climbing model.

What a way to spend a morning!

Thanks Ron and John. In the wet and windy weather of today I can hardly believe that was only yesterday

 The cut down prop is 12.5" on a 36" model so more 35%. It still destroys the glide to some extent but it does glide now . It'll be interesting to wind it up a bit more and see what happens when it gets some height and goes into freewheel

[Pete Fardell]

What an uplifting video! The Piper looks pretty good even just on hand turns. Can't beat a blue sky and a YMHM!

[Squirrelnet]

Thanks Pete, it was glorious weather...not sure where that went

Here's the job I should have done before going flying yesterday

[Pete Fardell]

Sorry, by 'YMHM' I meant 'YHWM' obviously! (I don't know what a YMHM even is!))
