Thanks for the servo feedback. Just checking to see if what I have on hand would work.
I'll add those to the order too.

This is all new to me and I really appreciate everyones input!

Should be fun.

Guys, please read posts #55 and #56. I put that info into this thread you help you out, assuming the 3DHS version has the same construction as the Skywing versions. Until you get official word that it doesn't, I encourage you to assume it does.


For the time being, it would be good if tominator could add that info to the first post, by linking to it etc. as until 3DHS clarify that their version of the Skywing plane uses different construction materials to the Skywing ones, I will assume the materials are the same.

Some of us Aussies have been flying Skywing planes in general for about 2 years and these 48" ones for almost a year, so we have extensive experience with Skywing's construction methods and have repaired their assorted planes many times. There is lots of info on the Skywing threads that should help you out at times, so please search those threads for tips etc. Otherwise, contact 3DHS since they will support their product.

The Tower Pro MG90 servos are rated at the same torque as the HS-65MG servos...and are rated to be quicker. The MG90 servos have performed well on my two Kalteisen EPP Extra 260. The Kalteisen EPP Extra 260 is a 44" airplane, with an AUW of 32 oz.

Kalteisen EPP Extra 260 Yellow - August 7, 2010 (6 min 55 sec)


Kalteisen EPP Extra 260 - June 10, 2010 (5 min 3 sec)


After 300+ flights and a few hard crashes, the MG90s are still running strong. I have to beg to differ .

This is what I've been waiting for in a foamy. I'm going to see if the guys at the RC Today Show Podcast will let me do a review of it!

Of course, I'll see if 3D Hobby Shop is cool with it too.

Yeah he said 9G Tower Pro, and when I searched that this was the first thing I saw.



At any rate... not sure why they call the larger one the MG90 9G, as they weigh 14 grams. At any rate, I tried them in the ailerons of my Buck Huck, and the ones I got are significantly slower than the HS-65s in the tail. I was pretty disappointed too, as they were stated to be faster.

The MG90s would work in the 48" Extra I suppose... but from my experience I think it would be a real trade of performance.

I misunderstood as well and was thinking of the 9gram servos. My experience with the HK servos is that their specs don't really mean much as far as speed and torque ratings.

I've had some that had a faster speed rating than a similar Hitec servo but side by side comparisions show something completely different. I have not tested many of their servos and I have not seen the MG90's so I can't comment specifically on those but I think my general understanding of the quality, speed, and torque of hobby king servos is correct. Maybe one day I'll be proven wrong.

Is this the servo you are talking about?

I use the cheap servos in planes like foamy park jets. They are well suited for that. Fly, turn, straight, turn, straight, turn, roll, stop rolling, etc. The precision doesn't really affect me that much with that type of flying.

If I'm trying to fly knife edge down the runway and see how close to the ground I can get the wing tip I like better servos.

Pretty sure he was talking about these. I've got a few of them sitting in a box in my plane room closet... I was really stoked by the specs, and they seem strong enough, but the speed just isn't there.

I've tried the MG90. They suck. Never buy again even though they are much cheaper than HS65MG.

It's possible to get a used HS 65MG for less than $15 each that still work way better than a brand new MG 90 (~$7.00)

ben beyer,
the mg90s is worse than the mg90 (less torque). the mg90 has a ball bearing and metal gears but the metal is softer than the metal used in "65's" and "85's" and like ALL METAL GEARS (except maybe titanium gears) will develop slop over time. then the hunting and overshoots seem to be worse or at least more noticeable and with the tower pro mg90 (aka... hxt's, grayson hobby's, turnigy's and others all made by tower pro) it just happens sooner. now if you could find the tp-16r digital with "karbonite gears" instead of metal gears (37 oz-in torque @ 4.8v)...

just my experience with more than my share of tp-mg90 servos
