| In this hobby, you get what you pay for, well for the most part. The 537 and 539 are cheap, low cost servos! That why Jr will pack them up with a radio. If you look, you will find Jr and Futaba will offer the same radio with different servos pre packed. Both have the cheap version and a more costly version.
Take Jr's new 9303, it can be bought with 811's or 8311's. The 811 equipped set is $599.00 and the 8311 set is $799.00. Why do they do that you ask? Well IMHO it's for the people who buy based on cost only and not looking to see if something is up to cut the mustard of their needs.
There are alot of people who will look at the $599 and say, "there ya go, I don't want to spend $799, it's a heli radio, those 811's will work in my heli". But what does that heli require? They don't seem to care, it's like there is $200 dollars saved that can be spent on bling. Next thing you know, it a nice looking, blinged out heli with the most important parts, the base of all control, being the "cheaper ones".
Heck, look at the specs:
DS-811,
Torque: 54.0 oz/in
Speed: .18 sec/60°
Dimensions: 0.75 x 1.49 x 1.52 in
Weight: 1.44 oz
Bearing: single
Motor Type: cored
If you thought digital servos were the exclusive domain of giant scale aerobatics airplanes and high-end helicopters, you'll be thrilled to know that JR has a digital servo for sport pilots. Benefiting from much of the same technology that goes into JR's premium digital servos, the DS811 Advanced Sport Digital Servo sets the standard in sport servos.
It is an excellent choice for sport applications, like 40- to .60-size pattern airplanes or .30-size CCPM trainer helis like the Venture™ 30CP. Matching it with a 4.8V battery pack yields an impressive 54 ounce inch of torque. Transit speeds are impressive too. With a 4.8V pack, the DS811 executes a 60-degree sweep in a brisk .18 seconds. Perhaps most impressive is that the DS811 offers all this extra performance for just a few bucks more than a standard non-digital sport servo, allowing anyone to enjoy the precise feel and unmatched accuracy of JR digital technology.
DS-8311,
Torque: 130 oz/in
Speed: .18 sec/60°
Dimensions: 0.75 x 1.54 x 1.36 in
Weight: 1.87 oz
Bearing: dual wide spaced
Motor Type: coreless
Created specifically for the demands of high-performance helis, the DS8311 provides a 125 oz/in of torque and a speedy .18 sec transit time. Its this strength and speed combined with JR's unrivaled digital technology that provides a feeling of precision in 3D flight that's more like thought control than radio control.
In short, you can't blame a product, good or bad run of them, if they are not up to the job to begin with. This isn't just the buyers fault either, I've seen too many times where LHS's will tell the purchaser, "heck ya, it's perfect for your needs". This usually is done just to get the sale and they figure if I stock the $799 radio then John Doe will just buy the $599 radio from my competition so why bother.
Don't come off the throttle untill you see your GOD! |
