Cheers sos,
A bit of common sense seeping from your words into my mind sack. After waiting so long for it, Ithink I will use the acoms till they die, there are 2 of them in the set after all! I can keep looking at the longterm replacement whilst enjoying the car, which I think will be this aft instead of going to antics (if I go I KNOW I will spend money!!!)

Cheers

Hi, I had an S3003 in my B4 as it was all I had when I built it. Its now been retired to my tourer and I've got an S3050, digital, metal geared and ballraced. Paid $45 for it plus postage from the US but if I were you I'd wait till the Acoms are dead, the ones I have are still not dead after years, they just keep getting downgraded! One for the Hotshot, one for the Hornet at the moment.

Anyone have any idea what pinion gear should i use for checkpoint 19t money motor? thx:D

try a 19 or 20 for starters

Agreed, was running these at my first race meeting with the car. 19 would be my choice, 20 is on the edge of being overgeared.

Hitec and Bluebird are two servo brands that I definitely would NOT recommend as I have seen problems with both first hand in terms of quality, fit and performance.

Also Tamiya do not supply servo horns for Hitec so that may cause hassle, you might have to bodge something together with Hitecs own part.


I just wanted to correct you on the Hitec brand servo not fitting with the supplied servo saver. This is not true, i own the hs 625mg and have no problems with this servo due to quality or performance and as i said the servo saver fits just fine.
A little off the subject of servos now, but i just wanted to thank you for your recommendation of using the remaining shims for the slipper clutch. I did so just after reading your post, and i am very happy i did. It would have been nice for Tamiya to mention something, but i guess thats why we have great forums like this and people with knowledge that can inform others. Thanks again.

Interesting regarding the pinions, I'm running a 20 on my 8.5 BL, I have been meaning to re-read Jimmy's review, Do I remember correctly that he said he used a 21t pinion on a 16 turn motor?

it's on page 4 of the review

"I chose to use a 21t pinion on the Peak 14x2"

Had a bash around last night and have to say that now the acoms have 'bedded in' it is performing quite well. Good enough to last for a bit anyroad.
So I was browsing the net and found the 631Mg on Rc Mart. Shipped (albeit via air not ems) for £15. At that price I just had to say yes!
Thanks for the help all

There is nothing wrong with Hitec servos!!!!!!!!!!!!!!!!!!!

I have used nothing but Hitec for the last decade after having too many expensive failures wi KO. I've not had any problems with them other than the occassional gear which is cheap and easy to fix. I have them in everything from micro to 1/8th scale and in all of my planes too.

WOOT! my DB01 slipper and titanium arrived! thank you mr.postman!:D

Does any have any idea any good and cheap servo for my Durga?

you need something ith a bit of torque as well as speed, try a google searh for a bluebird (some have slated, but there has been great improvements of late and I use them in all my cars.... 10th buggy and tc also in 8th truggy)

Proper mods tend to be a bit easier to gear than a stock or spec motor. They have a bit more torque as they usually run less advance, also they don't usually run laydown brushes so they run cooler.

I've swiched to a 12x1 Orion V2 in the Durga now and have an 18 pinion on it, only one tooth less than I would run on the 19x1 motor!

well i got a towerpro mg955 metal gear servo installed in my DB01 but i find it quite slow but torque is quiet good, you have any suggestion of which model of blue bird servo? cheers

in the TRF 501X review I used a bluebird 617. I'd reccomend that or the latest ones which numbers escape me. I only took it out of the 501X when I got a low profile KO so I could mount the ESC further forward.

I've been running Hitec for years and never had a failure.:cool:
The HS625MG is a very good servo for sensible money.

Shock Measurements
 

If anybody is interested in using them, my mate has built up his B44 shocks and the dimensions are as follows (measured from the top of the alloy Factory Team cap eyelet to the bottom of the shock rod eyelet):

Front compressed / extended = 63mm / 83mm

Rear compressed / extended = 72mm / 98mm

Not sure how these compare with B4 shocks though (sorry can't be arsed to take mine off to measure them at the moment), heck I haven't even checked the part numbers. For all I know B4 and B44 shocks might be the same parts.

Any chance you could re-take the measurements from mounting centre to mounting centre? I think the B44 shocks are the same size bodies as the B4 so compressed will be the same but the B44 has longer front shafts for more extension.

For the kit Tamiya shocks you subtract 7mm from the total length to get the centre-centre length.

which model is that Jimmy ...the KO PROPO PDS-2413 ICS ? ...it sounds like a good servo
If there is enough room I'm going to put my esc between the motor and servo and my rx in the transponder bay so no wires over the motor can(want a fast&torquey low profile digital Metal/Ti geared coreless servo)
