Servo question

[GreaTOne_65]

I was wondering if anyone has run into this before:

I was checking the operation of the ailerons on my R&R Snapper (changed transmitters) when I noticed one aileron was not centering properly, it would waggle before it centered. Always before I figured it was a dirty pot in the servo, and would change servos. This time I switched the servos side to side and it stopped waggeling.

When it comes to radios I'm dumb as a rock!!lol!

Sorry, I failed to state the Snapper has an 86" wing span, I'm using one 12" extention on each side plus the Y connector, with another 8" extention to the reciever, all Futaba.

So there you have it any ideas

I have had this problem with numerous Hitec Hs-605's. I have had both new and used do the exact same bounce when you center them. I contacted Hitec and they say that it was normal and was only exagerated by the use of larger control arms and surfaces. Never had a minutes trouble with any of my JR's though...

Thanks, for your reply, for me it came as a revlation!!LOL!!

I had had a number of servos act that way and always pulled them out and changed them. Usually I would tear them down and spray tuner cleaner at the pot, sometimes it helped, sometimes not.

The two servos that I changed were both brand new 3004 Futaba's so I was cussing out Futaba and their losey servos!LOL! I cannot explain my suprise when, by changing them around, they worked perfectly.

Thanks again for the reply, Fly safe, only perfect landings,

I've also had centering problems when using a reversing Y on elevator halfs. A change in temp will change the resistance in the pot and make the reversed half change center. It really gets tricky when you don't catch it on your preflight and have to scramble for aileron trim when you did not need it the day before.

Hi, again, Arron,

Thanks for the warning about reversing Y's, amazing because it just so happens I have one of those on a Lanier Cap 232! Maybe I'll take it out. I have had about all the problems I care to have with that plane.

Totaled one because it was tail heavy, had to add 1.5# to the nose to make it balance. By the time I added that much to it the thing flew like a streamlined rock! Well on the second one I put the servos up in fuse, with old fashioned push rods, wal-la no more nose weight! I haven't weighted it but I can tell you, it feels much lighter than the 1.5# of lead I had in the nose.

I have a FOX 3.2 in the Cap, what a beautiful engine the workmanship on that motor is superb(SP), it's almost a shame to cover it up with a cowl! I also have an early A&M Sachs 3.2 they both turn the same prop, 22X6-10 6800 rpms.

Later,

Dale

This summer I moved up to a JR 8103 and it will mix elevator halves with out the reversing Y. I could have done this with my lesser radio but when you added trim to the elevator only one half would move. I can now mix them and trim as if I had the Y.

At 1.5lbs lighter it should fly totally different. And sounds like the engine combo is going to be pretty exciting.

Hi, Arron,

Exciting? You bet! Relaxing? Hell No!LOL!!

I never have had an airplane that I had to throttle back on downlines or loops. Always flew with throttle stick bent forward! This airplane flies more like full scale, the flying surfaces on the Cap are quite large and with the Fox at full cry, this thing really moves! It is the most capable plane I've ever had, and after 24 yrs. I've had quite a few. I wish I was as good at flying it as it is at flying!LOL!

What are you flying? Do you belong to the IMAA?

Time to go, fly safe,

Dale

The only scale aerobat I have right now is a H9 Edge with a Saito 180. I also love my Aeroworks giant profile with a RCS 180. I've been recently shopping for alittle larger plane. And I think I have found it. The Wild Hare Edge 540T. http://wildharerc.com/Products/Edge/edge.html

Hello Arron,

I have seen the Wildhare, adds, looks like a nice aircraft. What are you planning to power it with? Gas?

A friend in the club has a new Lanier 300, with a G-62, the hottest 62 you ever saw. He is an engine guru, he built an expansion chamber out of an aluminium soft ball bat. He told me last Sunday he had been trying to get it to 8000 rpm's, I think he's using a 22X10 Zinger, any way he said Sunday he's made it now he's ready to fly it.

Another member has a different kind of 300 with a stock G-62 that flies really well. Last Sunday it was going fast enough the ailierons trembled when it went by, so landed it and haven't got a clue why they did, linkages are all slop free and he's using digital servos.

I have owned one G-62 and I'm not a real big fan, but these two are quite impressive.

Happy Landings,

Dale

Well I have a Brison 4.2 but I think it maybe alittle too much. I've given thought to the new DA50 and Brison has a new Revolution 50. Anyway it would have to be gas. Nitro makes power, but costs so much for a thirsty engine.

[GreaTOne_65]

The Brison 4.2 is a brute of an engine, what's the wing span on the Edge?

It looks to me that 80" wings will handle up to 3.2 over that it's "run what cha brung"! LOL

We've had some really bright, nice days this week, but I unfortunately I haven't got only a Gremlin that's flyable, and I've had other things on my mind to do, like a combine that needs my undivided attention before harvest starts, and 3 tractors.

My modeling days are numbered!

[Aaron Modlin]

Here is a link to the Wild Hare site. The Edge is 84" and weighs around 17 lbs. I also looked at an Aeroworks 31% that is 91" and weighs around 18-19 lbs. But it is twice the money and has the same wing area and loading.

Thanks, Arron, I put both websites on my favorites list!

2They are both beautiful aircraft. The Aero-works, is spectacular, and I would love to have one, but I think they have over-priced it a little. Your 4.2 would not be to much for the Aero, but you would surely have to much with the Wildhare.

Be careful when mounting servos in the tail, like I said before, when I put the servos in the rear of my 232, it was a disaster.

I noted, in the Aero Ad they promote the G-62. My experience with the G-62, has not been pleasant. I feel the Brison 3.2 or the FOX 3.2 are much more rugged and nearly as powerful.

Which ever way you go gas is by far the best way to go, MHO!
