I tried posting this in the Radio - Engines - Servos forum, but it seems no one cares to answer, so I thought I would try here. [:@]

I am ready to choose my servos for the SE kit I have just finished. I have 3 JR537 servo's from another plane that bit the dust. Yep, I have tested the 3 and they are fine. I am debating on whether to finish out with 2 more 537's or maybe a couple of Hitec 605BB's. However, I see that these are discontinued when I look at the Tower Site. So I guess I have two questions: 1. Are the 537's enough for the SE? (I think they are, so I am just verifying.) and 2. What Hitec Servo has replaced the 605BB?

BTW: My SE is pretty standard: engine is a OS46FX, and will be using a 12X5 or 12x6 prop

I run just standard servos in my SE and fly the heck out of it. You won't have a problem with them. I don't know the hitec servos, but any standard servo will do. It is a pretty small airframe. You will like it. I run a 46 fx and an 11 X 4 prop. It is a blast.

Have fun

Thanks FLYBOY
I thought the 537's would be fine, just wanted confirmation from someone that had one. I also had time to find the chart that shows prop sizes compared to engine size. I will probably back mine off to the 11X4 as well. The chart indicates that the 12x5 and 12x6 are too large for the 46fx. I still am looking for a comparable servo by Hitec so I can substute the new one for the 605BB's. I have another plane in the wings that will probably need a step above the JR537's. (Choosing Hitec mostly due to the cost.

I used Hitec 425BB on mine, and they were plenty. I think they have somthing like 44 or 48 in-oz of torque if I recall.

Just noticed your prop question, which depends on the type of flying you want to do. I had an OS 50SX on mine and used an APC 11x6. Flew it nicely. Many are opting for the APC 12.25x3.75 on that same engine to get better aero/hovering abilities. I bought the prop, but put the plane in before trying it out, so I can't comment on it.

Thanks P-51B,
I did put on a larger landing gear just for this purpose. I do have some 12X6's sitting around and after the engine is broken in (it's NIB) I may move up. Thanks also for the 425 information. I thought they might be the ones, but I can't remember the torque on the 605bb's in order to make a comarison.

I tried a 12 inch prop on mine last weekend for the first time. It sucked. Had no power, no vert, no speed. You could hear that the engine wasn't turning. I put the 11 x 4 back on and had fun. 12 seemed to be too much. I used to run 10 x 6 props on the 45s. 11s are good but 12 slows it down way too much.

46 fx go with a 11x6

That's pretty much what the Chart says as well. The 12" ones are out of the recommended area for use.

12x6 is ok for a K&B 48, but the OS 46 won't like it much.

Thanks all, I stopped at my LHS on the way home, bought the 2 537's, an 1100mah battery (this is my standard for now) and will use the 11X4 prop...for now.

I appreciate all the input.

I realize that you already bougt servos. But here is a suggestion anyway. I have some Hitec HS-475HB's that I am going to try. They have 60 some inches of torque. The new carbonite gear sets. But unfortunately only 1 BB. But the price is right I payed 24 bucks at my local hobbie shop. I have seen them listed at 19 mail order. Got some heavy duty Dubro servo arms and ball links. With Robart control horns and clevises. Should make a real tight set-up. good luck with your somethin extra.

Phread59 has a similar set-up to 605's... The 605 I believe had about 70 oz. @4.8V, For the price I like 645MG's but they are slow (.20?)
You DO NOT need anything other than STD servos on the SE- Yes it will fly better with digital servos but...$

I love the SE

I also just finished My Something extra Kit (what a piece of cake ) However I Bought the kit on ebay and it came with the os 46 la so thats what im using for now please tell me that will be ok and what prop to use with it Thanks, Mike

Mike- I see that you are hooked! Welcome aboard...

The 46LA will be fine, I always say "run what you got"- I would try an 11x4 or 11x5 APC if you want lower speed, more torque- 10x6 if you want to be quicker (not common with the SE)

Cheers!

APC 11x4, only way to go with the .46 engines, I am using JR 811 digital servos with mine, lots of torque and I had them left over from my 8103 Heli package, you can pick them up for 30-35 bucks sometimes from the heli guys because they buy higher torque servos, and they are perfect for sport 40-60 planes!

hi just love my SE !!!!! she has a Irvine .46 red case and a APC 11x5 prop and all standard radio equipment servos are Hitec 425BB 1100 ma nmhi !! Oh man I just love that SE
If yours flys like mine your sure to love it too
