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.

The count of 25 does not include the unbuilt kits stored in the loft.

25 at the last count! The Blenheim is a nice flier but can be a bit tricky to get away and needs a good launch.

This post is slightly tongue in cheek as my wife is very understanding about my hobby and lets me do what I want within reason.

I keep telling her there is a difference between need and want!

Yes it’s a Balsacraft Blenheim.

Yes I don’t mind, many electrics nowadays won’t arm until the throttle is opened fully and then shut of again. My injury was my fault because I did not restrain it properly whilst running and the model slipped out of the restraint.

Broke the prop that’s all thank goodness!

Just a reminder that electric models can bite , this was my little comet racer which slipped its restraints and bit me!

I picked this up for free from my local club. Any ideas what it is please? It has a 31 inch wingspan and looks like it might have been a kit built but can’t be sure. Many thanks Cliff.

Blimey I thought mine was well used but it’s a spring chicken compared to some of these models!

I did some maths last night and worked out that my Durafly Spitfire mk24 has spent 21 hours in the air on a conservative estimate of flights and am average of 5 mins per flight! This got me wondering what other high usage models might be out there?
