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.

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.😢😢

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.

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

The esc are 4 max supplied ones.

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?

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.

That’s true Brian does seem odd.

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.

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.

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!

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.

No one at the club could fathom it , even our resident Futaba expert!

I should have said I fly Futaba and the tx is and 8 FG super with a genuine Futaba 8 channel rx.

I have an odd problem with my comet racer, it is set up how I always do twins, ie both esc signal wires into one channel one a y lead with the red wire disconnected on one esc. The throttles work fine but if I shut the throttles then use elevators or ailerons one motor will briefly run. The rudder does not seem to affect the throttle. If I go into the servo monitor function on my tx nothing shows on the throttle channel when using elevator or aileron! I have tried deleting the model completely then re setting it up to no avail. I am at a bit of a loss, any ideas anyone? thanks in advance. Cliff

No Frank it’s a Cloud Models Westland Whirlwind.
