Can also suggest, if you have a spare Rx to substitute that for the one in the Citabria and see how that performs.

Take a good servo and check it on another model set up with the transmitter. Then plug the servo into one of the sockets of the two affected ones. Does it droop as per those. If not then cancels out servo problem. If it droops then Rx or TX.

If it was a range issue then wouldn't the servos return to normal when back in range ?

Coming a bit late to this but have you tried a different RX ? I was going to suggest the same a Dickw and see if the servos returned to their "normal" mid position when trying one of the other Rx outputs. I can't see it being a problem with the servos as both have moved the same amount. That is unless there was a mechanical issue due the crash impact. i.e. - Both servo arms jumped the splines ? If none of the above then I would suspect some change in the TX.

Is this what you need :- https://www.justengines.co.uk/shop/engine-spares/two-stroke-spares/a-s-p-two-stroke-spares/a-s-p-s25-spares/?v=79cba1185463 Shows one gasket on the back plate and two on the head.

Not built this but you could draw up your own plan. Use the rib length to work out the comparative fuselage dimensions. Or, with the BB plan, you can always make a built up tail. I did my own similar many years ago (1990) and still going strong. Originally with a clapped out Enya.15, although now with a clapped out OS.20. From 40 seconds.

You don't need telemetry to fine tune. The LED light on the receiver will go out (or change colour) when it looses the Tx' signal. So adjust "fine-tune" one way until the LED goes out. Do the opposite way and then set the midpoint.

A couple of YouTube videos: In comments of the second video it mentions being in D16 mode. EDIT - There is also V1 and V2 firmware besides EU / FCC firmware.

For a pusher prop (although could it be used as a tractor one ?) how about a "Pushy Cat" - Outerzone :- https://outerzone.co.uk/plan_details.asp?ID=7091 Not sure about your motor/amps/battery size. ?

Are you getting the flashing of the green LED after setting the failsafe ? This same thing happened to me a couple of days ago. Switching the kill switch set the motor going. - I hadn't ticked one of the boxes to "enable" the setting in the "special functions". Double check that everything is set exactly the same on both planes.

Start again - Rebind the receiver. This will cancel any failsafe that has been set. Set the the Tx sticks to the failsafe position (Usually throttle low/off.) Press the failsafe button on the Rx for less than 1 second and the green light should flash. Test to see if it works. NB. To calibrate the ESC you do not need to turn the receiver off. Yes it will be off because the battery to the ESC will not be connected. Disconnect the ESC, move the TX stick to the high. Connect the ESC and it will beep. Move stick to low position and ESC will beep. That should be it.

Not used SLEC but have used Balsa Cabin a few times. Problem is when I only need a sheet or two the P&P costs are more than the balsa. I have seen something at Wickes which caught my interest (polystyrene sheet) but can't find it again atm.🥴 I don't do a lot of building these days - have too many models and not enough time or talent to fly them. But I get the urge now and again to add another one to the fleet. ( don't tell the wife about my urges. ) I really need something that will withstand finger pressure on the wing leading edge box section and I don't know if Depron/polystyrene will do that.? Not sure if anything will beat the properties of balsa. Thanks guys. John

Many years ago I built a couple of Pete Russel's 362 deltas. https://outerzone.co.uk/plan_details.asp?ID=10014 The first as per plan but the second I used corrugated cardboard ribs. The tubes of the corrugations were vertical with cap strips for longitudinal strength. Still using balsa for the sheeting etc', and it's this that would need substitution. I recently saw an electric 363 delta (362's big brother) and it has got me thinking. 🤔

As a returning modeller, Is there any thing that is a replacement these days instead of balsa sheet for wings etc ? It not so much the cost but poor access to shops that sell it. Perusing the pages of the forum etc', a lot of modellers are using some form of "plastic" block/sheeting. If I wanted to build a wing obviously there would be ribs and balsa sheeted sections. Would the only alternative be something like polystyrene (Depron) but the building technique would have to be different. As say a solid & sanded aerofoil section ? But then what sort of weight would it turn out to be ?

Durafly "Slow Poke", and thankfully it does fly slow. I'm returning after a good many years of not flying so I need something to hone back the skills. Maidened yesterday but initially very twitchy on both ailerons and elevator and had to dial in loads of rates down to 30%. The model initially comes with the linkage connections in outer holes on the servo arms and control horns. I have now altered the servo linkage connections a lot nearer the servo centre. There is no guidance in the instructions as to the amount of control surface movement. Plenty of videos on YouTube showing its capabilities and something to aim for.
