Model Forum / Radio Controlled / Land Models / January 2006Savage Servo's
Can I have some suggestion for which servos to put into my HPI Savage? My steering servo has stoped working and I don't know anything about servo's. Thanks for the help. > Can I have some suggestion for which servos to put into my HPI Savage? > My steering servo has stoped working and I don't know anything about > servo's. Thanks for the help. For steering: Hobbico CS-70MG/Hitech 645MG or equivalent (metal geared, 100oz/in or better @ 4.8V/6.0V) For throttle/brake: Hobbico CS-64/Hitec 635 or equivalent (70oz/in or better @ 4.8V) You want a meaty servo on steering and a slightly less meaty but high speed servo on throttle/brake. On steering, I'm running a Hobbico CS-70MG (metal geared) @ 6.0V which gives me 133.3oz/in @ .20 seconds. I'm running a Hobbico CS-64 servo on throttle/brake @ 6.0V which gives me 83oz/in @ 0.15 seconds. With this setup, steering response is quick and powerful and throttle/brake are just as good. Instant throttle response and great braking power. I'm a huge fan of Hobbico servos as I haven't had one break on me yet. Doc Thanks for the advice - Not a bad price either. >> Can I have some suggestion for which servos to put into my HPI Savage? >> My steering servo has stoped working and I don't know anything about [quoted text clipped - 14 lines] > > I'm a huge fan of Hobbico servos as I haven't had one break on me yet. Never tried a Hobbico - I use Hitec 645 on the steering, and 625 on the throttle. I've bust a few Hitecs before though - next time I'll be getting something better I think. Good servos when they work, and it's probably just that I bash too hard for them :D  SignatureDan I had the 645MG on my savage and it couldnt turn my big joe tires so i up graded to the hitec HSC5998TG the cost is a little pricy but well worth it. my steering is right on the money now. good luck..... http://photobucket.com/albums/c170/Marks324/ > >> Can I have some suggestion for which servos to put into my HPI Savage? > >> My steering servo has stoped working and I don't know anything about [quoted text clipped - 19 lines] > something better I think.

I've heard very good things about Sanwa servos.

Looks like someone has purple fever ;) How you finding that OS .30? Also is that a Robinson Racing spur and bell combo? SignatureDan i am only about 7 tanks into the break in on the OS it is still very very rich so it is no powerhouse yet but i can see where this truck is going to be crazy fast. and yes it is a Robinson Racing Spur & Bell 14/52 i am going to change when it get this engine broke in. too a 17/49 or something like that >i am only about 7 tanks into the break in on the OS it is still very > very rich so it is no [quoted text clipped - 3 lines] > when it get this > engine broke in. too a 17/49 or something like that I have the 16/48 and it works great with the K4.6. 14/52 with an OS 30 will be uncontrollable for wheelies :D SignatureDan >>i am only about 7 tanks into the break in on the OS it is still very >> very rich so it is no [quoted text clipped - 6 lines] > I have the 16/48 and it works great with the K4.6. 14/52 with an OS 30 > will be uncontrollable for wheelies :D Ya know, I just read RCCA's dyno review of the OS .30 and it's really not all that great spec-wise. It peaked at 2.72HP and 35,000 RPM. Hell, my $129.99 (HALF the price of the new OS) Sportwerks .26 puts out more HP (2.75) and almost as many RPM (33,000) as the new OS motor. With all the 3.5HP+ .30's and .32's out there, why the hell did OS make such a wimpy motor? If you read the results of all the national races, both on-road and off, very few if any of the folks making it to the A-Mains are running OS motors. I know they have a great reputation, but they're comparitively overpriced, underpowered compared to their competitors and are rarely seen in the competitive environment. Doc Hmmm...... Didn't catch that link before.. OS.30?....Nah... How you finding that (is it a?) Thunder Tiger .70?? > >I had the 645MG on my savage and it couldnt turn my big joe tires so i > > up graded to [quoted text clipped - 4 lines] > Nice truck and buggy!

Details :D SignatureDan I did have the Thunder Tiger Pro.70BX in my savage and man let tell you what a Peice of sh.t engine that was i blew that engine 2 times in 3 tanks of fuel. and if you goto midmad.com and look at the EK4 thred everyone that has had that truck has blown there engine it is the same TTP.70 so i pulled that and put in the OS.30 kinda wish i would have bought RB or the calari.32 >I did have the Thunder Tiger Pro.70BX in my savage and man let tell you > what a Peice of sh.t [quoted text clipped - 3 lines] > that and put in the OS.30 kinda wish i would have bought RB or the > calari.32 The Collari is next on my wish list. 3.7HP @ 36,5000 RPM! Look out! Doc Hmmm.... Thunder Tiger usually makes stuff pretty damn tuff, but ofcourse I guess that is what can happen when a company tries to pass off a helicopter motor as a monster truck motor. > I did have the Thunder Tiger Pro.70BX in my savage and man let tell you > what a Peice of sh.t [quoted text clipped - 3 lines] > that and put in the OS.30 kinda wish i would have bought RB or the > calari.32 |
