Thread: Warning X8R RX - do not use with CDI on IC powered 'planes
12/06/2019 07:12:26

It’s not just the cap to plug fitting, as that can be easily seen on a CM6 type plug, it’s the HT inner wire / resistor / cap connections inside the cap that can form a gap and cause arching.

@TOC - my advice would be to swap both X8Rs for the R Pro RXs, or, like me go for the R9 module.

Thread: Slowing down (a sports-aero) on landings - flaperons or spoilerons?
06/06/2019 13:50:56

@JonathanM - I have a grossly overpowered (5s - 6s) WOT4 that I use spoilerons on and these are very effective much better than flappers that I first used.

Easy enough to take the end caps off!

Thanks Tim. Despite having flown some of my electric ‘planes since the demise of Sbach 342 (2) I took to the air with the new one with more than a bit of trepidation! I shouldn’t have worried as it flew really well. Before the flight I did a long range signal test by driving about ¾ mile away with the TX then spoke via mobile to my mate in the pits to make sure controls were working! Fortunately there were no low signal messages from the telemetry. So I’ve no replumbed the tank all ready for next flight.

To replace the Sbach 342 I lost a few weeks back, a new (to me) Sbach but this time a 300. Once again power by the Laser GA30 which has been rebuilt by Jon at Laser, having to fit a new crank, bearings and a new carb as all were damaged in the crash. I first took the 300 up to the field last week but had a problem trying to start the engine which was eventually traced to a broken hal sensor magnet in the prop driver. Replaced and back again today but had a problem with the engine cutting out, forcing me into dead stick landings but no damage. Back at home I found that the tank's plumbing wasn't quite right for the GA30 (plus a stupid oversize on my part) which was allowing air to get into the system. Now all fixed. However I am very pleased with the performance (despite the dead sticks), with plenty of power from the GA30 giving it a sprightly performance despite it being a bit heavier than the previous Sbach. I also tried Aspen fuel for the first time, not cheap but as Jon has mentioned, much cleaner than standard petrol oil mix.

Yes, simply unplug one from the RB10 or switch off on the TX. I plan to leave the TX with a mate then take the ‘plane  in my van, 1 mile away then check if it’s receiving.

The trims can be ignored when setting up the various stages. Here are some brilliant documents to help understand the process:

Inputs

Mixes

Outputs

And here is the original post from the guy that did them:

Thread: ARTF tail feathers - what glue do you use
28/05/2019 20:36:38

Having previously used epoxy on several ARTF I have now changed to Super Aliphatic where there is a good fit. But I've also experimented with Gorilla glue where the fit wasn't that good and that was / is fine. The only issues I have with cyano is that it isn't waterproof (shouldn't be an issue!) and its not fuel (petrol) proof.

@Alan - I use the R9M module in the external bay of the Horus and both this and the internal module seem to be fine running together. I've only done garden testing with it at the moment but will do a full range check plus failure checking when I'm up at the field on Friday. I've looked on line to see if there are any potential problems but haven't found anything, so I'm going to give it a go.

@Andy - thanks. I still intend flying my electric powered 'planes with the X series RXs, including my 2m F3a, fingers crossed but I work on the basis that if I haven't had a problem over the past 4 years with maybe 30 different 'planes then.....................

@Peter - thanks for all your help and I'm disappointed that the capacitor approach didn't produce a solution. Like you I do believe that it's a problem with the components but I do still need to test one last thing, that is to instal an old version of the firmware, if I can get one that is!

Looks like they’re rebuilding the site but they do provide both tel number and email addy in order to contact them.

Thanks Barry. TBH that was the way that I used to set all my 'planes up, rates and expo in the mixes, it's only recently that I've changed to putting in the Inputs as it's far less work to do when changing them if not using GVs.

Thanks to PeteC I have now carried out further testing but with different sized capacitors on the power lines, unfortunately the X RXs still locked out. So having now replaced the Sbach 342 with another Sbach, this time a 300 I have installed the following:

R9 RX running 868 Mhz

RX8R Pro RX running 2.4Ghz

Redundancy Bus 10

2 x 3000MaH 2s LiFe batteries for RX

1 x 2500MaH NiMh battery for ignition.

Great news Jon! On another note, GA30 running sweetly in Sbach Nr2 having replaced the magnet. Hope to ‘maiden’ it on Friday.

It’s on YouTube, Essential RC put it up a while ago. Looks really good.

Thread: Petrol engine cutting out on take-off
24/05/2019 16:59:43

I’m not a fan of the nose up test, but in this case it could eliminate some possible problems. I would suggest only holding the model at 45 degrees, not vertical, and see what happens then. I had a similar issue with one of my engines which, on closer inspection, was a small split on the fuel feed, when level it was fine but as soon as the nose was raised air got in and the engine cut. New fuel line cured the problem.

Like Cuban, been there with mother in law over the last year or so, time with mum is so much more important than work, go with it Jon, my thoughts are with you matey.
