When Futaba firmware updated started to come with the LBT mod I stopped updating my 14SG so it would retain compatibility with all my FRSky receivers as some of them didn't have the option to be updated. Now I wouldn't know which were bought before FRSky made them work with the latest Futaba FASST TXs. If there are identifying marks which show they are the latest build it would be worth knowing about it.

Ronos, Spray the plan with WD40, this will make it transparent so you can turn it over and get the mirror version.

Also as an owner of a 14FG there is still the option to use FASSTest or FHSS. If original FASST receivers are no longer available from Futaba, I would imagine FRSky will be producing compatibles for a while yet.

Rustins plastikote works on acrylic car type aerosol and cellulose paint. Any paint that is oil based won't fair well as plastikote contains solvents which will attack it.

Rocker, I suggest any ARTF model designated as a 30cc should suit.

Charlie, Before you modify anything try flying the stall-turn by putting on a short burst of throttle just as you apply the rudder, this will give it more authority.

Brian, I have been looking for plans of Matt's Superstar, may I ask, where did you get them from. Thanks, Andy

I can't imagine the average plod having any idea what the rules are. It will be interesting to see what encounters with the law happen from now on. They may be a bit shy of making a deal out of imagined incursions after the, oh so public and expensive, pig's ear the Sussex Police made of the Gatwick affair.

John, It's curious that the engine will run on a 2 stroke plug and not on an OS F. I suspect the fuel because when I have had fuel go bad it would first fail to run 4 stroke engines but seemed OK in 2 strokes. I wonder if this is why your engine will run only with a 2 stroke plug.

To follow up on my post above, see this article from the BBC on phone number spoofing... https://www.bbc.co.uk/news/business-56934517 The rule is never give any personal details to anyone who phones you even if you are convinced they are genuine.

John, Given a few months to harden, enamel paint is reasonably fuel resistant but there's nothing like a 2 part fuel proofer.

John, Why not just use acrylic type car paint or cellulose paint for the colour coat then Rustins can be put directly on top with no appreciable delay and no chance of wrinkling.

Nigel, Rustins Plastic coating isn't available in aerosol form due to the two part mix required. I use Rustins with added thinners and sprayed using a spray gun although I take appropriate precautions due to it's toxicity when airborne.

John, I would think Rustins will react the polyurethane so definitely try a test piece first. I have heard there are blocking coats you can use to allow hot paints over cooler ones but these aren't the stain block type.

John, Rustins contains thinner that is not compatible with enamel paint. The rule is to put the "hottest" coat on first which means the one with the most powerful solvent. This is because you don't want subsequent coats to dissolve the ones on underneath. I have heard of hot coats sprayed over cooler ones but it has to be done very carefully by dusting on the first layers so the solvent almost dried by the time it hits the paint underneath.

Nigel, I have had it fitted for a while but I haven't run it yet. I will have to take it up to the flying field as running it at home may be one run too many for the neighbours. 6 x 1 minute runs at full throttle with absolutely no tick-over, this is what Brian has prescribed for running-in. I'm not sure what prop to use but probably a fairly light load like a 12 x 8. These liners are made to the Hanno spec rather than the original RF spec which means the exhaust timing is slightly different. I understand that this will mean more torque at a lower RPM on my RF.

Don, I've been rereading your post and it seems to me that if the pipe comes on tune when revs drop wouldn't it have been too long at higher revs and not too short. Shorter pipe for higher revs, longer pipe for lower revs.

I don't speak Spektrum but other radios have the option to feed through the trim mix through from the master function or not as required, could this have been deselected somehow.

Mike, Hard Glaze is one of the newer water based varnishes that come from Dulux and Ronseal, It's like Deluxe Materials Eze Kote but much cheaper although you have to buy a minimum of 1 litre. It can be used instead of epoxy for finishing a glass covering etc.

I have used 1000 grade lining paper on EPS foam with good results but I have always filmed it afterwards. Next time I may try attaching it with hard glaze as the PVA I have been using tends to shrink too much. I suppose it depends on the water content of the of what you are using.

There's a thread on RC Groups where you can put you're name down for a replacement piston and liner set for the Hanno/RF as many of them had problems with the original liners stripping their plating. The guy who makes these operates from Australia and he makes a superb job of them, I had a set he made in the first run. Ian, it's best to take the head off and inspect the liner before you use it. See this thread... https://www.rcgroups.com/forums/showthread.php?3380853-Making-ABC-piston-liner-rod-pin-sets-for-O-S-61SF-RF-engines-(tally-in-OP). Brian is taking names for a second run so if you need to recondition your engine now is the time to get on the list.

Things that cause aileron flutter are... 1. Ailerons that go all the way to the wing tip without some sort of aft wing tip protrusion 2. Ailerons that are rounded off at the trailing edge or are too sharp, these should be left square 3. A central servo with torque rods that are too thin and twisty. If you hear a sudden loud noise like a rubber band being twanged, this is the sound of flutter, throttle back immediately, otherwise it will destroy something. Of course it's not just the ailerons that can flutter tail surfaces can also do this if not rigid enough.

Some years ago I took my B test with an Acrowot it didn't recover from spins consistently because I had the CG a long way back so it was just luck it came out OK on the day. There are better models, when I first flew my Sebart Angel and went through the B test manoeuvres it almost seemed like cheating it was so easy.

It would be useful to have someone on here that does IC cars as they always use air filters. I have looked through what is available but they are always designated to particular engines so it's difficult to know what would fit an aero engine without a lot of buying and error.

Scam callers spoof a different number each call they make so it's very unlikely they will use this number again. This trick renders websites like whocallsme.com useless for tracking these scammers.
