A good rule-of-thumb is to choose a servo with about 1 ounce of torque to every ounce of foamie weight. Example- Your 48in Juka with a weight of 28 ounces will need approximately a 28 ounce torque servo.

so HXTs won't cut it. Go with 65MG or equivalent.


Bingo- thx.

Thx Army. I have HS55's all the way in my 40" Juka and they take a pounding & do great.

On this post I was looking at servo options for the 48" Juka I just bought.

The hxt900s certainly are cheap, but I'm not sure where you got 'junk' from. Many people have used them for a long time and they gave proven them selves to be excellent.

Hey Guys,
I tore the elevator off my Yak in some tall grass. I cut new parts and everything fits together fine.

But I'm wondering if the voids (holes) cut in the trailing edge of all the control surfaces does something aerodynamically for the plane. My new elevator has a solid trailing edge. Does anyone know if I'm going to detect different flight characteristics because of the new solid elevator?

The photo shows the original elevator that I removed and the new elevator (solid trailing edge) that I installed in its place.

Thanks,
Marc

i would imagine the holes are there to help increase drag on the surface thus increasing effectiveness at low speed?

just guessing but i doubt you feel a difference.

I agree. I doubt that you will feel anything. If you look at the new Yak 55M all of the control surfaces are solid.

The holes on the control serfaces are somthing Mike used to put on all his old foamies, and they are mainly for increased drag over the serface. It is hardly noticable, and infact I used to tape mine over because it flys a bit better precision. I would't worry about it.

Red- duly noted...and I retract saying 'cheap'. 'Extremely Inexpensive' may have been better.

I hear over and over again ad infinitum: "you get what you pay for". Regardless, Mike wouldn't sell Hextronic if he didn't endorse & support them.

It's just hard for my feeble brain to accept that a $3 servo performs as well, and presumably for as long, as a 'name brand' $25 servo.

Oh well.

I was pretty tentative about having $3 servos on my pride and joy foamie that took a long time to paint but I've had two 40" Juka's with HXT900's exclusively with not one issue. My dad also has them in the wings (4) flaps and ailerons and no troubles whatsoever.

I would make up some hitec stickers for you if it would make you feel better

I hear ya, bro!! I already made up some little Futaba stickers, since my brain can't handle exceptions to the "get what ya pay for" rule!!

In most things in this hobby its true, but IMO the cheap HXT900s can't be beat. I've tried cheap everything else, and have gone back to splurging for namebrand stuff as it's usually cheaper in the long run, except for these servos.

I've used maybe 20 or so, and I had one show up that didn't work right. But the ones that I got that worked, have stayed working for tons of hours of flying.

Yep, and I guess that proves there's an exception to every rule (I may have even used this saying a time or two!!).

Too bloody bad the 900's aren't recommended for the 48-incher I'm getting.

Drat!!
