Car built very nicely except for the 2 speed, should get the replacement screws tomorrow.
Very cool. Thats a good starting weight. I'm looking forward to hearing how the new layout runs on the track. Thanks for keeping us updated.

I've got my spektrum. No more interference! Too bad it's late, otherwise I'd go run some laps in the lot. If tomorrow or any other day is great I'd go for a run. Funny thing though my Futaba actually almost as fast as my hitec 625MG so I'm wondering why buy/have em? I'd probably get rid of the two I have and use the S3003s laying around. Sure the Hi have more torque, but the futaba's work just as great. Time to sell all the other stuff.

Hark: Yeah those 625's are baffling. Let us know what you think once you race with the s3003's. I thought my 625 was a bad unit it was so much slower than my s3003.

Also yeah spektrum is the best. I have a spot out in front of my house that sends my buggy I play with careening out of control. Without a doubt I drive it down there.....and I tense up and hope it can make it through without smacking a pole or something.

Now its nothing but sweetness. Allthough one time on the track I do believe I got a nasty glitch....not sure though could have been a funky servo or error on my part.

But yeah when you drive with an s3003 its pretty smooth and your not really worrying about killing a $60-70 dollar servo so I kinda drove with less worry and more just get out there and go.

There also so cheap if you ever have a doubt theyve been messed up you can easily just buy another without even a second remorseful thought. As well there some of the lightest & least power draining servos you can buy.

Worth a try for some of you....

Also forgot to add they probably are working faster , not sure of the response of the original unit you used. But the spektrum uses less power in the RX and TX generally.

I know with my TX I insert the spektrum vs the oem RF one and automatically my TX will display a higher voltage on tap. It also says this somewhere on spektrums website.

You can probably look up response and voltage use and check it versus your stock stuff to see if this is right.

Yeah the S3003 have always worked for me. When I lowered the throttle travel for my Hi, they seemed to run a lot slower. Why? I have NO idea, but I don't like it. They are both being removed from the R40 and maybe the GT. Both sold for a nice $50.

my fav servo for the price is the futaba s3305.. plenty of speed and torque, metal gears and only $35..


maybe I should trade my r40 in for a rc boat.. its rained 23 of the last 24 days here and they say its not going to break any time soon....
