Hi Danny - I have a question. I have my LT-40 with JR 537 standard servos and the original 4.6 volt battery that came with the flight pack. This makes the battery two summers old. I happen to have a brand new 1100 Mah 6.0 volt setting on the shelf.

Can I use the 6 volt battery on these servos or will I just tear the threads off the gears?

I have a JR radio I can program the expo down so it slows the servo down a little due to the higher voltage.

What do you all think, just buy a new 4.6 or go ahead and use the 6?

Weight is not an issue. As a matter of fact I have a little bit of lead in the tail now I might be able to take off with the added weight of the 6 volt up front to off set it.

Thanks for any help

I don't know half of what Danny does, but I *think* he'll say something similar.

I have standard 537's on a Stinger .60 with a 6V 1100MAH battery and they do fine. The only problem I have had is that when the battery is fully charged, a few of the servos will get the jitters until the charge drops a little bit. I changed out three different recievers before I figured out it was just the 6v battery doing it lol. You can use a voltage regulator for about $20 to stop that, but I never have. I can't prove it, but I think I did strip a servo once from the jitters, but not from flying....

After that initial jitter charge wears off I don't have any problems with them at all and the 6v increases torque and speed a little. Just my .02

Thanks for info Rick, that's what I was looking for and hoping to hear. I have a note to Danny, but haven't heard from him yet.

Will probably swap out batteries tonight and do a new CG on the plane so it's ready for this weekend to knock the rust off of the thumbs from this long winters no fly weather

Thanks

A 6 volt pack will work fine, on a fresh charge it may cause some slight jittering, but should cause no serious issues.

Thanks Danny - pretty much what Rick said, so with that the old battery comes out the new 6 volt goes in.

Hi Guys - Well I swapped the battereries out last night and did a new CG on the plane It was about this time I kind of remembered saying something in my RCU post about "not worrying about the extra weight in the nose because I had some lead on the tail I could TAKE OFF if I needed"[X(]

No wonder you guys said Good Luck. That was a little backwards [X(]

Needless to say I left the lead as is, but was actually able to move the battery back a little even though the new battery is 1/2 again the size of the little 600 x 4.6V one I took out. I guess I've had it a little more nose heavy then I should have for some reason. Will have to do a little trim tomorrow to compensate for basically the new CG. The nose is now just slightly lower then the table on the CG machine.

Happy Flying

Have fun with your plane! Let us know if you have any further questions.

Unless for reasons you haven't mentioned, you might consider just moving your battery aft for balance. I have or have had 15 different planes at one time or other and have never added any dead weight to any of them (yet). At most, I might have added some additional strength or epoxy to make up a little weight that I might not have used otherwise.

I know in some cases there is no other option, but as of yet, I have always used the onboard equipment moved around to get balance. In the pic I attached, you can see where I placed the RX, the 3 servos and then put the battery in the rear to get the balance. It's not the greatest pic, but it was all I could find of a plane at that angle and in that stage of building... I guess it should be considered a Top View though it's a side pic. (it's a Stinger .60) The servos are pretty much where they had to be, but the battery was supposed to be next to or under the RX. In this case I used a servo extention and put it almost 8 inches from the RX. Your case might be different, I just hate to add dead weight. Just a thought, but always something to consider.
