Bergen R/C Helicopters > JR large servo wheels

I'm ready to test fly my gas-powered Berger Intrepid EB, but just find the original servo wheels that come with my JR4131 servos are not large enough for the service.
I know somebody sells larger servo wheels but had a crash in my computer and lost the name/website.

Can anyone help me on this?

Many thanks.

Actually the small JR wheels will work if you use these holes specified in the drawing for the Collective, aileron, and elevator, instead of the dimensions spelled out in the manual for Futaba servo wheels.

I'm having the same dilemma. Chris when you say small wheel, what are the actual dimensions you are talking about. Can you be more specific like you are in the manual for the Futaba. Can you give the set back and diameter dimensions for the JR? Thanks for the info.

The small servo wheel is appx 1" in diameter. It's the one that comes with the servos such as the 8311 or the analog servos.

I just received my first 8611 servo last week and it came with the LARGE servo wheel of appx 1 1/2" diameter.

If you look at the picture I posted, you will see 2 sets of "six pack" holes and 2 sets of 3 holes in a row. The highlighted hole are the ones you put the balls in.

On the LARGE wheels, you will only have 2 "five packs" and 2 sets of three in a row.

Here is an excerpt from the latest edition manual,


Quote 
At this point you need to have the servos plugged into the receiver and powered up. All servos need to be centered. This means trims are centered, all sub trims are zeroed, and any mixing is turned off. Using a straightedge of some kind, make a line from the center of the bellcrank to the center of the servo wheel, in this case we will use the elevator system. As you can see, we have turned the wheel so the straightedge travels through the 3 hole sides and the 6 packs are equally spaced on the side. Mark the rearmost, outermost two holes on the wheel. This is where you will install the servo balls.
Concerning JR wheels, you may notice a number on the backside of the wheel. There are at least 5 different wheels that we know of. If you can’t get a certain wheel to center properly, rotate it 180 degrees. If that doesn’t help try a different numbered wheel, available from Horizon.

Chris and Buddy,
I thank you for the info I needed, proven info is better than guessing and crashing. It's better to be close on spec rather than having to make other adjustments. You guys are the best.
My new setup is JR 8611a all the way except throttle.
Soon to be installed, I hope !!!!

Chris,
thank you and all the others for the prompt reply to my question.

I'm a little confused, now.
I notice for the pictures that are in the new manual, that the aileron servo is installed in the upside position.

Mine is installed in the upside down position, as per pages 51,52 and 53 of the Manual I have. Ist this correct or not?
Thanks.

Either way works.

With the original canopy, the servo had to be upside down so the pushrods would clear the front canopy mounts.

With the new style canopy, the mounts are now behind the mainshaft, so are clear of the pushrods.

Mount the aileron servo whichever way is better for you.

I guess I should have specified a little more, that excerpt came from the latest Turbine manual.

I have the Gas EB manuals completed with the needed changes for that bird, as well as adding in a parts listing with a picture of each part to make inventory and ordering replacements much easier.

The Observer EB has a completely new manual, and also includes the parts listing for that bird.

All manuals are on CD, in a Word document, with the viewer included, and a few videos of the heli in action.

If you have the new bird with an older manual, let me know and we'll get the latest version out to you.

My EB is almost a year old now (time to get that birthday cake ready). So I don't think that the manual I got is outdated.

The reason for my question is mainly that I hoped that I could find all those neat tricks posted here on RR in a bundled and easy to look up fashion.

BTW, I wish you had noted the trick about the JR servo wheels in that version of the manual that I got. Would have saved me some sets of servo wheels trying to get the push-pull just perfect. But then again, all that time, you were just a phone call away to give me that info. I should have called....

Kind Regards,

Jan Dewerchin.
