Decent servos for a fair price

I've used many high end servos for indoor planes- hitec 5035/Jr 188/Futaba 3154/dymond d47, but they are at least $25+ a piece (I know that dymonds are for $20, but they are hard to get locally).
I have a lot of different projects for which I would like to get some cheaper servos and I have already tried a few and have been dissatisfied. What are your opinions for cheaper (up to 10-12usd a piece) digital (I know that d47 is not digital)servos? Max 7g of weight and preferably smaller (thinner) than HXT500.

Indoor servo DSMS309

Hi,

I use last year at the WC and IITOP the Topmodel DSMS309.
In 4.8volt, it's perfect. Very fast (As fast as JR188) and very light (3.25g and 2.55g without wire and bottom case ;-)



Regards,
Nicolas

Thanks,

FWIW, in Coburg the Japanese were using these, however they were not completely happy with the centering:

HK sells something that looks very similar:

I have a few of each, but ran out of time last indoor season to do anything with them.

The HK-5330 servos are great! I have only used them on minis. I would get a bunch of them, they get CA in them really easy when you glue them to the plane.

I am currently using them on my 32" pattern plane. They are working great!(on 2s)

I should have mentioned that I was rather thinking about something for freestyle, I already have a good setup for F3P. I have an indoor flying wing which I got for tests and it needs something stronger than the ones mentioned.

Nicolas I have two of those servos for rudder and elevator for my F3P plane
I have those HK-5330 in my micro radjet and had 4 of those in a 50g Extra, which I have made. I was very happy with them, but they are not strong enough for 140-150g aeromusical planes. In those you need at least a 2kg*cm servo for ailerons(I use futaba 3154/3157), something fast for elevator(strong enough is JR 188/319) and good for rudder (Hitec 5035 is ok for just the rudder, but if using vector thrust you need 2 or one larger Futaba).

The only reason I looked at the NIne Eagles/HK servo I mentioned was because of weight.
Otherwise I am willing to pay for good servos. For my Arrow V6 I put in JR DS290 all around, per Donatus' recommendation. All on 2S direct. If I was going to do vector he suggested running the rudder one on 5 volts.

Some pilots use the DSMS309 in 2s but my opinion that is not good for the reliability.
So in 4.8volt the DSMS309 is already very quick.

I have ordered some gening 4.7g servos and will test them soon. For 11 USD shipped for each they may be a good choice.
Those servos have been used by a friend from Czech Republic and he is pretty happy with them.

Have you considered the tailservo of the Blade 340 3D ? A little bit heavier (not stripped), but faster than a DS318/118 and nearly as much torque on 4.8V.

1 centering precision accordingly to the specs of E-flite.

But the price is 19USD and my goal was to find something much cheaper up to 10 USD.

FWIW, finally got a quote back from Topmodel for shipping three of the DSMS309 servos to Canada. (Took them a week and a half to get back to me)

Three servos - 37.80 euros
Shipping - 45 Euros

Ridiculous, just had a bigger box shipped from Germany for 15 euros. Small boxes from England are a few euros.
For 45 they should be shipping overnight fedex.

I guess they, or erhaps the French postal system, don't really want to do international shipping.

Same here. Something is wrong when we in effect are subsidizing our major industrial competition with these ridiculous low rates for incoming goods while hammering us here at home. Not that I want to pay more for shipping stuff from China/HK , but fair is fair.

FWIW, I confirmed that the 45 euros is shipping only, not the total for 3 servos plus shipping.(which is about what it should be). Package from Germany had 5.5 euros as postage.
Are French postage rates that much more expensive, or is Topmodel just not interested in sales to North America?

Thanks to a helpful PM I was able to buy some of the Topmodel servos from Aerobatics.be.

Much more reasonable shipping costs, and very prompt replies to my inquiries.
