Status: offline 		I've been with my club for a couple of years & have to say it wasn't too bad to get through the wings program. I had my bronze wings within 6 weeks of starting up & gold wings inside 12 months, admittedly I was on the simulator at home for a couple of months before I went out there, & working on 1/1 scale Learjet 45 simulators probably helps a bit too.

Flip, we do seem to be the dumping ground for most electronic stuff that doesn't sell anywhere else. So I guess we might be on the end of the pecking order for models too.

Status: offline 		I think both of you are correct in the debate of mods to arfs, I have to agree that the quality of arfs has improved dramatically in the past ten years however there is still much room for improvement. I don't think many arfs are built to withstand the high output Jetts etc. that we stuff in them an example is a sonic that I own that the firewall came loose on, it turns out the whimpy 1/4 inch firewall was hot glued in and not very well at that. I modified my firewall on my viper due to numerous reports of the firewalls coming loose. It wasn't long ago somebody lost a magnum when the wing came off, I had already modified my wing attachment prior to flying and tossed most of the stock hardware and so far keep my fingers crossed as hard as I've tried mine has stayed in one piece keep in mind this is a plane designed and marketed for high output engines. From what I've seen most arfs are fine for sport flying even hard sport flying but not for extreme speed which is what we are talking about. Those of us that have built the flanker have had to make mods due to flutter weak points on the landing gear mounts etc. and this is not quality control problem since we are doing the building it's just a simple matter that the plane wasn't built around a jett 90

Status: offline 		Hey Crash or Blue, what prop are you/did you useon the F20? I tried a 11X6 for my maiden cause that's what I had, but it was to long and hit the snow easy when it sank in. I bought a 10X7 today at the LHS and will try this next. Now don't laugh at the engine I'm using, it's a OS LA .46. I wanted toput my Tower Hobbies .46 in it but long story short, Tower took it back after the problems I had and I just got the LA because I have had such good luck with them. I needed, I will put in my OS FX .46.

Status: offline 		currently on my OS50sx , I'm running a 10 x 6 .

1) cause its a good run in prop,

2) when I bolted on my 9 X 8 , I didn't notice that the blade was to wide (as in pitch) for the backplate, so when I took off the prop I noticed that by tightening it up it notched the blades of the prop..so of course I wont use it..

but now I have to find out if it's ok to sand small recesses into the root of the blade so that it will clear the backing plate.. but to answer your question ..I am intending to use something like a 9 X 8, but this will be open to experiment's once I get the ringed 50 satisfactorily run in, so a 10 x 6 or 10 x 7 will be on there for a little while yet, maybe 10 or so flights before I'll start mucking around with props

Gd day mate: Do we want to gamble a $3.00 prop against a complete airplane or serious injury. Nope! Charge it off to another lesson learned in the hobby and future. Its a cheep lesson at this point. If you will only use it on a say 40 LA, sand the rough spots of the notch and leave it alone. Murphy's law will eventually catch up to the thing and you, chuck it. My Alley Cat is coming along slowly. Tail feathers are on, servos in and connected, front end wood work epoxied, wing joined. A fiberglass center section is not called for, will do it anyway. want to keep this one for a while. Am going to try the stock landing gear, will only hold up to great landings which will be ok except following a race heat. I am one of those people who focus so strongly during a race, everything is blocked out except the race. In the past, I have been able to divert the adrenaline rush to raceing focus intensity with no after affects. Now I get shakey like the rest of the guys, unusual for me. Now part of my focus is keeping cool. The joy of winning is still there, the agony of defeat is more intense, it hapens more frequently these days. Its part life and getting older, but just not acceptable to my basic nature. I recall a 80 year old from the bay area in the 70's who was just flat the guy to beat when racing. His engine never failed to start and run correctly, he flew the course like he was on rails, never cut etc. So, I know it can be done, now I just need to find how and follow his footsteps. If someone else has done it, I (we) shoule be able to acomplish close to the same thing. Hope you guys are enjoying the hollidays down under, and have good weather on days off. ENJOY.

Status: offline 		G'day rmenke, I know your right, all the warnings on props tell you to chuck them if they are scratched dinged or chipped etc
its a pity because the damage looks so minor , but I know that "minor" could easily turn into major damage should a blade let go in the wrong place..something I never ever want to experience..

as for the Holidays , yes typical aussie weather , we getting a heat wave in the next few days of 40 degress celcius or in your lingo 100+ f..so no time to build planes, I have to get my mums air-conditioner installed(replacement larger system)

Status: offline 		The weather has been weird the last few years, but June /July arent that bad, sure on odd occassions we get like only about 10-15 degress cel.(about 50 - 60 F)during the day but its not unusual to get up to about 23 - 25 cel (70F +) , in fact this august we took the kids to local pool for a swim.. the thing with July is that is does get warm but only for a short period say like from 11:00 am to about 2:00pm ..outside of those hours its can be rather cool to cold..(cold by our standards).
ps at night in July it can drop down to 0 degress cel(32 f) but we can basically fly all year round.. ..September/ October can get a bit windy but thats the worst of it.

one point about summer though, some covering film doesnt hold up to the heat , they get rather wrinkly, I remember when I first finished my F4 Phantom( Vmar..and this isnt the best example due to VMAR quality film covering ) It was the middle of summer, I took the plane outside to take a photo, by the time I put the plane on the ground , ran in to get my camera..the covering wrinkled so bad it would have given a 100 year old granny a run for her money on a wrinkle count!!!

cheers

Status: offline 		Looks like our snow may be melted enough for me to put my wheels back on for our kRaZy SnOw FlY this Sat. Unfortunately, at our events they usually only want you to fly already flown planes and no maiden flights, but if not many people show, it may be possible for me to get a flight in. I'm still worried about my antenna that I ran inside the fuselage. it's totally in the plane and goes up to the firewall then down half way through the other side of the fuselage. Anyone ever have any issues when doing this?? Some club memeber advised me to NOT run it around servos and now it is pretty much going around the two front servos.

Status: offline 		wish I could help Flip, all I know is that the wire shouldn't be doubled back on it's self as your reducing your radio range, now I'm not sure if what you did qualifies as doubling the antenna and halving the range..but your fellow clubbers are right about the servo's etc... I would love to run my aerials internally..but from what I've heard about interference from internal components gets me to nervous to try a complete internal route.. I love my planes to much to wreck them over something stupid I may have done.. so I run mine as far internally as the model allows then let the rest hang out or use a piece of sticky tape and run along a wing or fuse depending on the model and usually underneath..

Status: offline 		Flip,

There are quite a few guys racing pylon that do exactly what you're talking about and have been doing it for years. As long as you get a good range check you should be fine. Actually, there are some guys that are just wrapping the antena around a straw and the sticking it to the inside of the fuse. There's a small "how to" article somewhere on how to do it... I just recently tried this on my beater winter plane and everything seemed fine. I'll probably start doing it on my racers... Just make sure and do the range check...

Status: offline 		Hey guy sorry I hadn't repiled, Xmas time & all that.

I had the antenna installed completely inside the aircraft, & it range checked fine. I used the antenna straws that the RC car guys use & cut them to get the antenna into a rectangle inside the aircraft without touching itself & effectively shortening the lenght of it. We run 36Mhz here so our antenna's are a bit longer than yours.


Where I live the weather is a bit different to where Roger is in Sydney, as I am about 1200 Km's north. Our average temp during winter (July) is 22deg C. It does get cold in the morning, but is back to 22 by 10 in the morning. I couldn't imagine having to wait for the snow to go away to get outside, I have never seen the stuff !!!

Tony.
