You must use good epoxy then. I use crappy 5 min epoxy that does not stick to servo very well. I avoid the "popping out" by using several tight rounds of sewing thread around the servo. Best method if you ask me. The servo stays always and it's easy to remove if needed by cutting the threads and just pop it out

Chris,
I used the Plastic Padding that was similar to Goop/Liquisole for elevator servo, I made cross patterns in the casing with a very sharp knife. It's stuck like glue

I have used hot glue with good success. Fairly easy to get the servo out if need be.

I have used the same method as Stuntman for ages and never had a problem.
I only use the 5 min epoxy. No flex, you can peel the shrink off it with the servo out and as Shawn says it makes a bed in the right spot for the next servo if necessary. Must rough up the shrink wrap before the glue though. I use the clear hard shrink wrap used for small battery packs.

How's it going Chris ?

Had hoped you'd got it in the air by easter.

Updates please

I was hoping to be flying the Lanyu by Saturday, but I have hit a problem with the ailerons. I spent all last night trying to get differential on them but I'm not having any luck. The main reason is my radio, an old JR XF631 that I bought when I didn't know any better. I have managed to get by with it until now, but I'm thinking it's time to upgrade. Pity I'll have to wait a few weeks for that.

I have tried setting the servo arms forward to get differential, but because of the aileron construction their down movement is very limited. This would normally be ok, but my radio can't set the end point of both aileron servos in flaperon mode. No matter what I do I just can't make it so that the down servo end point is little enough to stop binding. I can only set one aileron end point, as setting the other (on the flap channel) is dedicated to flap movement. Because I am going to glue the servos in I want them properly set up before they're stuck. Anyone got any ideas?

My next question is what radio would you guy's recommend? I can't justify spending money on a top shelf unit unless I'm prepared to wait even longer, which I am if I find a radio I’ll never grow out of. Right now I am thinking along the lines of the Hitec Optic 6, but their are so many Tx's out there I'm not sure what else would serve my purposes. I would like a radio that would be able to handle hotliners (with a button I can use for throttle. Can you do this with the Optic 6?), flapped sailplanes (so I can use flaps and ailerons together, camber, crow etc), and electric scale and pattern type models.

2.4 Ghz would be great, but I'm not sure the DX7 has enough features to make it worthwhile when we will all be able to convert our radios with the XtremeLink or Spectra modules anyway.

What radio do you use and does it do everything you need it to?

The new JR 2720's look like nice versatile sets. My dad just bought one and its looks pretty good. No dedicated sailplane function, but plenty of mix's to do most things anyway - Rojs have them at a pretty good price.

9X VII is very good - the best and easiest radio to use I have had to date - does everything I want too (except for a timer that turns on and off on throttle but maybe I just need to sit down and work it out ). You wouldn't grow out of this set any time soon.

The 9X has a removable module so you can update later to 2.4Ghz when the these come out if you desire also.

cheers, Shawn

Chris,
If you are going to upgrade the radio, I would highly recommend those Spectrum Radios, DX7 or even DX6 over those conventional radio sets. I have been using DX-6 with the stock AR6000 rx in my CAT #1 for some time as soon as they were firstly landed in HK--AMAZING is only word in English to describe the satisfaction got from them. Then I bought another AR6000 to put in my Aquila xL , a simiple semi scale motor glider by FVK, perfect too.
I then bought a DX7 set and an extra Rx. One has already worked in my EXCITE, it is a very tight airframe, flown it more or less with lucks with those US brand ESC, THAT CRAPPY 80 ESC claimed my little Astroflight 05 when it landed on a bush and that infamous 'auto start' extra function 'properly' so fried my little 05- ...gone ...(worst is 05 has been discontinued.... With the AR7000 ,the routine glitches were cut down A LOT even with those Chinese made ESCs. being used in that same EXCITE, significant improvement in RF interference issue are easily feel especially when it flies towards myself and in low alt.,............ Another AR7000 is going to my RW Full carbon.

I think I will bite my CANNON,and replace ALL existing conventional ppm RXs in hotliners or high carbon content ships, with those AR7000 as soon as possible for the sake of my wallet.

In fact, I had been upset much with those mystique and ghost like RF jams issue with my Profi 4000/ IPD,FUTABA double conversion rx combo, for quite a long time before the release of those magic like Spectrum tech,... For that matter, I bought a 9Xii and I am satisfied by the SPCM transmit mode by JRs, got 2 10ds, and few pcs of 790 , all of them has indeed paid me back much in RF interferences problems.
The greatest drawback of the JR stuffs to me is the shortage of timer fxs compared to Futabas, and MPXs. Also the programming is another problem for me after years usage of MPXs, it might NOT be due to any deficiency of JR or other popular brands.
Chris, regarding your 'doubts' if the stock DX6 or DX7 could fulfill the 'needs' in hotliners , I personally would say no problem at all. In my CAT#1 , I am using 5 of 6 ch and 1 of the 3 'FREE' mixers. And similar 'simple' programming is being used in the Excite, the Aquila xl. And the most 'complex' programming to my RW2carbon, is ..spoilerons, T.E. controlling in take off, thermal, landing...Be frankly, when I 'first' learn (I use a 9C and then mpx,then JR,now DX) to prog the DX 6/7, I do feel so easy and fresh!! no brain is needed......everything (MOST needs) is set , just input the numbers....
Again the only shortage I meet during these months of usage on DX6/7 is again NO USEFUL TIMER ...= JR's stuffs itself.

I also do not consider to buy the aftermarket RF modules for JR/ FUTABA txs because :
1- VOID the warranty
2- NO surprise in features,
3- skeptical mind about 'bugs'.
4- not cheap
And like many other things, ideal is yet to come, so is an ideal tx. Hope the XTREMME owner could work out those goodies as he 'promised' ,And more ideal radio set would be that NOMADIAN designed by the ex-mpx dealer,Kaltron.(right?) The 'FREE' mixers of MPX's Profi 4000 is still the most versatile / flexible when 10+ ch are to be programmed'.

Don't install Spectrum DX6 or 7 in composite fuselages. The signals are blocked by the carbon and you will have o range. The radios also don't have and sensible glider functions built into them. So for now, at least with this generation of 2.4Ghz radios steer clear, at least with the mouldies.

Not sure this is correct. See here and this thread

However, at the moment I would not buy a spectrum due to the programming limitations...but if Multiplex bring out a spectrum module, who knows?

I think your model has ailerons only? Personally, I would not bother with flapperons. The benefit during hotlining is minimal and you might even make it worse by inducing high speed tip stalls. Thermalling is only marginally improved with dropped ailerons and once again there is a real risk of tip stalling if you try a tight turn.
What you DO need is the ability to raise both ailerons the same amount as spoilerons for landing. I used to be able to do this quite easily in 1990 with a Futaba FF7, so I would imagine that most computer radios from the last 10 years can be programmed for this set up.
If you do need a new radio and you're on a budget and keen to get flying as soon as possible, I'd suggest you buy the cheapest radio that can do what you need. At the moment there are very few radios that you could buy and feel that you will still be using it in 10 years time. Exceptions would be the very top end radios from MPX, Futaba and JR.

Thanks guy's for all your replies, this is the friendliest forum I've experienced so far

The topic of radios is obviously a personal one and I am interested to hear what you all have to say. For someone like me who is a relative newcomer to the world of computer radios it's a daunting prospect to choose between the dazzling array available. The advertising doesn't usually tell you what you want to know, and after reading through a couple of manuals I realise that I'm not going to find out all the in's and out's until I have used one for a while. That only makes choosing one even more risky.

Mike,

Don't worry; I'll be using spoilerons. I said flaperons because that's what the manual refers for this function. I tried both with my warmliner and fully agree with you. I also tend to agree with your spin on getting a new radio. I see I have two options.


1/ Pay big money for something that will last me the next ten years. This will mean saving for the next few months first
2/ Get something for around $300 now that will last a couple of years, possibly more, and then get a fully optioned dedicated 2.4 Ghz radio when I will be able to afford it. Hopefully they will be available in a few years.

My question now is what are the best radios in the $300 AUD - 124 GBP - 245 USD price range and above? I can get the Optic 6 for $285 AUD and the JR 2720 for $369 AUD.

Also I would love to assign the throttle to a spring-loaded button, but the Optic 6 only allows it on a two-position switch. How do you guy's do it on your radios?

Hi Shawn,

I travel right across Melbourne to Roj's Hobbies. Best service and prices I have found in this City so far. I had a look at the manual for the JR 2720 too. It looks good. Now I'm getting confused though. Is anyone using the JR 2720, the Optic 6 or any other similarly priced radio?

Chris,

Have a look at the new Multiplex SX. The price is quite reasonable for a 12 memory computer radio and it has all the features you need. Multiplex offer a different programming setup and feel to most other radios. There was a write up in Sept'06 QEF&I.

I haven't had a chance to get my Lanyu in the air as yet due to the poor weather.

Hi Swift,

I can get he Multiplex SX for $435. It's getting a bit beyond what I can afford right now, but I have the Sept'06 QEF&I and will read it again straight away! I wasn't even thinking of a new radio the last time I read it so thanks for bringing it to my attention. Is this the radio you use?

Good luck with your Lanyu maiden. I look forward to a flight report.

Chris.
