Must get on with the markings now.

Finally managed to get the maiden done on my Beaufighter today. Went really well, flies really nice and a peach of a landing!

[Ruler, metric/imperial]

As an engineer I come across both and can use either. I tend to use which one seems easier at the time. If I am doing a rough estimation of something I will use the one that it comes nearest to. Such as I need 20 meters of something or I need 3 feet of that!

There are some strange mixtures of things. For instance chain comes in imperial sizes but metric lengths.  So you order 5 Metres of 3/4 inch pitch.

[Ruler, metric/imperial]

A rule is for measuring a ruler is for drawing straight lines. If you look on a rule the measurements start at the end but on a ruler there is a space before the measurements start.

My old RAF instructor would have a fit if we called it a ruler,

So far we have done a 4 ship which was 4 small planes fixed together in a diamond shape, a space shuttle, a witch with a kite type cape and superman.

No a Foamboard wing and balsa fuselage.

We have a group at my club called the old farts club and we build odd things. Here is our XB90 Valkerie on test flight today.

I might have to change the props for different colour ones, the orange spoils the look a bit!

It was a bit windy at my club Saturday but I decided to maiden my B29 anyway! Went really well.

[Never mind the weather - who has been flying, then?]

I have definitely picked the right week to have time off work! 5 days flying on the trot! Bit warm a couple of days but still enjoyed it. Back to work next week.😢😢

[Old Warden 27th and 28th July - who's going?]

I will be there Sat weather permitting.

Thanks for that Paul,

do you have experience of them? If so do you know cg position and control throws at all? 
There are two marks under the wing which might indicate cg position but would be nice to be sure.

I also bought this recently at BMFA swap meet.

Picked this up last week. I think it’s a Tony Nijhus kit.

Summers here? Really! This is the view from my club hut today. You would not think it’s summer, cold, wet and blustery.

[Odd problem with my Comet Racer.]

Sorry Denis, I’m not sure of the significance of that?

[Odd problem with my Comet Racer.]

The esc are 4 max supplied ones.

[Odd problem with my Comet Racer.]

Bit of an update on this. It seems to be some sort of issue between the esc and the rx. The comet was fixed by fitting an orange rx. I tried the original Futaba rx in a different model which has the same make of esc, same problem so I thought must be rx. I then fitted another Futaba rx in the second model and low and behold same issue! Then fitted an frisky rx and problem went away. So it seems there is some issue using that make of esc with a Futaba rx. Any ideas anyone?

[Odd problem with my Comet Racer.]

I can confirm it is definitely the rx. Fitted a different one in this model and all ok. Fitted the suspect rx in a different model and bingo same problem, throttle briefly runs with aileron or elevator. Must be some sort of feedback or something? Strangely it’s fine with a servo plugged in throttle channel so might still be ok in an IC model.

[Odd problem with my Comet Racer.]

That’s true Brian does seem odd.

[Odd problem with my Comet Racer.]

Thanks everyone for your help. I have tried a different receiver and it seems fine so I guess there is something wrong with the other one, some sort of internal feedback or something?

The old one was a Futaba R617 FS so not a cheap one.

[Odd problem with my Comet Racer.]

I don’t think it’s my tx as I have tried two other models with no issues. I suspect it might be the rx . If I unplug the elevator and aileron servos the problem goes away. Then I plugged a spare servo outside the model into the elevator channel and the problem returns.

[Odd problem with my Comet Racer.]

Doing some more investigation, the elevator causes the motor that’s esc still has the red wire to run and the ailerons cause both motors to run. I have to admit I am baffled!

[Odd problem with my Comet Racer.]

I was thinking of trying a different rx. I don’t think it can be the tx or something would be seen on the servo monitors surely? The aileron leads and the esc signal leads run together through grooves under the wings so could be some interference there I suppose but that doesn’t explain the elevator as the lead for that runs the opposite way along the fuselage to the esc wires along the fuselage as the servo is rear mounted.
