Si, Futaba specifically say not to do that (wrap in foam) - so I'll stick with their instructions! I generally mount on a block of foam and secure with a zip tie..Rich
-
thanks BEB, i will give it a try...Rich
-
Thanks BEB, that's very well explained. ok, so for newbies to expo, how do we setup for the first time? what is a good starting point. not wanting to get it wrong and have a model that is uncontrollable!! Rich
-
yes, i only went with those digi ones because they were cheaper than futaba analogue jobs, if possible i usually go for the servos recommended for the plane by the manufacturer....Rich Edited By Dickster on 25/04/2013 20:47:41 Edited By Dickster on 25/04/2013 20:48:07

Posted by Biggles' Elder Brother - Moderator on 25/04/2013 15:44:53: Erf - you have a very good memory! I did indeed. Actually I played around with that quite bit afterwards for both Futaba and Spectrum expo curves. I found that no matter what you did with an actual curve of the form: y= A*(e^(x-B)-1)-C (which is the form you'd expect it to have) you could never get a really good match. You could get close but it was never really "right". So I've come to the concusion that what is actually in your Tx is not truely (mathematically) an exponential function. Its a polynominal approximating an exponential. Since then I've discovered that others have come to similar conclusions - in fact one guy (not me!) has found that for JR Tx the function that seems to fit best is a cubic polynominal of the form: Y = (Exp/10)E-05X^3 + (1 - Exp/100)X where "Exp" is the percentage exponential used (0-100) and X is the stick movement (0-100) Its likely that actually implementation is via look up table derived from a function such as this. I did actually email a question to Futaba Tech Support asking them what the function was - I got a very polite reply declining to tell me! BEB what did he say?!! actually, i'm glad the op started this thread, as i have never used the function, and i do not like using rate switches (i can never find the right one). so i usually start with low rate throws and go from there. so if i have the high and low rate settings how should expo be set (instead)? if the low rate throws are 75% of the full rate, you need 25% expo? as per post above..Rich Edited By Dickster on 25/04/2013 20:28:22

Posted by Glyn R on 24/04/2013 16:42:33: I have used small digitals because they tolerate 6 volts better than analogue. the ubiquitous 9gramme servos are often not happy on 6 volts. I like to use 6 volts to give more headroom for the 2.4ghz Rx. O f course you dont have to pay. See here Edited By Glyn R on 24/04/2013 16:45:38 Edited By Steve Hargreaves - Moderator on 24/04/2013 17:05:16 Yes, those are the ones I have in my Pulse 125, I thought I would try them (they are cheap!!) as they have great reviews - so far so good....Rich Edited By Dickster on 25/04/2013 20:12:01

went for a cheeky fly last evening, took the minimum kit with me, got up to the field, unloaded, mmmmm, no wing bolts!! i didnt give up, packed the car back up, went home, and fetched the bolts - still a little windy last night though...Rich
-
The old version with the brushed motor is very sedate (that's what i have but i changed the motor after a while), however if you want to join a club (i dont!) then that would probably be the best way to learn (and avoid mishaps) - although you may get a lot more stick time going it alone...Rich
-
Granted, but the op doesn't have the budget for a decent radio yet...and mine only has three ch's, its fine for learning. Edited By Dickster on 25/04/2013 08:03:25

This one in the link has everything you need (its a great price btw, i've seen it for £200 in other places): **LINK** You will struggle to do it for under £100.. Rich Edited By Dickster on 25/04/2013 06:43:46

Great restoration work..Rich ps glad the maiden went well

Posted by Ed Kershaw on 12/04/2009 12:24:20: but also b) it requires an advanced level of control over the model that I would like to aquire. Exactly why it is my goal too - I want to be able to do it!! Rich

Tonight at work......Black Horse Pitts
Rich too replied to Turbycat's topic in Scale and Semi-Scale kits
Excellent, cracking looking model, and great that it fits in the car assembled. Rich -
Ah, in that case get back on the saddle. Losing a plane is a pretty rare event in my experience. Stick your name/number inside the plane in future - and in the old days you could buy a buzzer that went inside the plane to help locate it in corn fields etc - not sure they're available these days? I have the Orange RX's and they are fine by all accounts - I just wouldn't trust them in anything expensive or that means that much to me. Rich Edited By Dickster on 24/04/2013 06:49:59

I think one may be a "kit" version. There is also an Easy Star II with ailerons - it depends on your budget? You will have some one off set upo costs initially, a couple of batteries, charger, radio etc... here's some more options (ready to fly, and radio ready..) **LINK** **LINK** **LINK** If you can afford it i would recommend buying the radio separately. Rich
-
The Easy Star wouldn't be a bad choice, cheap and spares readily available - I bought one as I hadn't flown for a few years..Rich ps welcome.

I lost one similar to Peter, I sent my glider up the bungee and forgot to switch on the receiver - did a lovely freeflight though! I got it back because I always put contact details in gliders..I don't want to discourage you Danos but you have to be prepared for these things. I accept that all my models will end up in a black bag one day. And I had a friend that fancied getting into when I was a teenager and he spent days/weeks building a glider (made a great job of it) and the first flight ended in disaster - literally dived from a great height into tarmac - total write off and he never touch a model again, he was extremely angry about the whole thing. Horses for courses...Rich
-
That decision is usually out of my hands! Rich
-
I don't see how it can be nose heavy if you are having to input lots of "up" when inverted. However, having said that, with that big lump up front (bigger than the rec motors?) i would be surprised if it wan't nose heavy. One poster on HK said the his flew great with the cog in the middle of the wing tube. Rich ps whats the auw? Edited By Dickster on 23/04/2013 13:02:39

Which circuit direction do you fly the most?
Rich too replied to David Ashby - Moderator's topic in Model Flying Polls
Hi Martin, I don't fly at a club so can fly any which way I want - just watch the sheep! Rich -
Ah, thanks Simon. I'm a bit technophobe with all this - I just like stuff to work when I plug it in and turn it on!! Rich
-
i've got the 7C FASST system. Does that make a difference? Thanks, Rich
-
Yes, I read about that, and I thought later models were modified? Although a couple of elevator servos in the tail would add some much needed weight to mine! I may just do that in the future...
