I gonna get a mojo 40 arf from BHRC but want to know what i need for a setup. I'm just starting. What type of Futaba servos should I get, digital or standard bb's. Do I need a mini or micro reciver, or would standard be all right. I'll get a micro servo for the throttle. Should I get an O.S. .55 AX, Saito .72, Saito .82, or O.S. .46 AX. I got a .46 AX on my Ultra Stick but still wan't to fly it. Should I get a new motor for the US or MOJO. If this is confusing please ask me to clarify.

Thanks a lot in advance

If you've already got some spare standard servos -- then use them. Avoid the temptation to use mini-servos for the flying surfaces -- you're going to have some prangs and mini-servos strip much easier than standards.

If you want to buy some new servos and like Futaba then lots of folks like the S3010 -- it's plenty strong (90oz/in on 6V) and also pretty fast. What you really ought to do (if you haven't already) is use a 5-cell pack for your receiver. It makes a lot of difference to the power and speed of your servos. I like the 1050-1400mAH 2/3A packs that you can get from a variety of sources. They're light (just over 4oz) and provide lots of flight time. They're also heavy-duty enough to use with digital servos on bigger planes if you decide to do this later.

As for receivers, a standard-sized receiver will be fine if that's what you've got -- otherwise you can save an ounce or so by going to a smaller (but FULL RANGE) unit such as an Electron 6 or LightFlightRC D6 which (at $27.95 plus crystal) are hard to beat -- value-wise.

Any of the engines you listed will be fine -- but if you're thinking 4-stroke I'd go for the 82 over the 72, there's not a great price difference but the 82 is a much stronger and more reliable motor than the 72. However, I'm in favour of learning 3D with a 2-stroke because they cost less so you won't be so worried about dorking it and therefore be a little more willing to fly "on the edge" :-)

But, when it comes to flying profiles, my motto is: "Use what you got and fly what you use -- until your thumbs start bleeding" :-)

I use std servos on my Mojo40 and don't feel the need for more. I have a Burrito and a Mojo 40 . I have flown them with a ys 63, OS 50 and OS 46. If I were buting a new engine for this type plane it would be the SAito 82. I have the Saito 91 on on my Mojo 60 and love it. I don't need more power. The 82 on the Mojo 40 is more than adequate. The OS 55 should have enough power and I like a smooth 2stroke but like Saito 4 strokes a little more.
