Hello,
I recently picked up at a swap meet a u-can-do 3d .46. Plane looks awesome and well built.

My question is about servos. I am thinking of using JR 537 servos in this plane, or maybe the DS537 servos, but in reading the specs on web sites it says it needs 50oz servos everywhere and 90 oz servos on the rudder.

Are the 537 servos enough? Are the DS537's noticably better (even in less demanding planes)?. Or do I need better servos all around?

Finally, well a .46fx run this pretty good. I'm going to order the tower hobbies muffler that seems to get good comments.

Thanks for any assistance!

the JR 537 work fine on my UCD .46 but what you should get is a servo that has the 90 .oz for the rudder...and if i were you i would get a engine that will pull you out of a hover fairly easy...i have a saito .82 on mine and it pulls out with no problem but i guess it depends if you wanna spend the money.

Thanks for your reply. I keep thinking I can go ahead and put in the 537's and, I guess, if I don't feel there enough then maybe upgrade later. But I have been thinking that rudder needs the extra boost, so thanks for that input. The seller of the plane to me told me he had a 46fx on it and it flew ok, and I have one laying around so I thought I'd try that first and then, again, upgrade if I'm really liking the plane after that.

If anybody has any comments on the 537 servos versus the DS537's (Or knows if JR is planning any new robust flight packs in the near future) I'd like to hear input on that?

Thanks!

I have the standard HITEC flight pack with 4- 425'sbb, and I have a HItec 5475 digital on the rudder, havent' flown it yet but should be great...
