Can't use high speed mode with analog servo's on my 4PKS-R.
4x grams is plenty light for me.

The savox 1250 I just put in is a mini servo not micro, and is just something I want to try since a few people on here said mini servos worked for them, originally I was using a savox 1251 and had no problems, also the servo horn is the same as the standard servos so I didn't have to change any thing there.
If this works I'll shave 30 grams, I'm trying to get to 1300.

I'm not sure what you are referring to here, Bert. A digital servo will operate with an analog radio with no problems-- there's no need to buy a new radio. Using an analog servo with a digital radio that has a fast frame rate can cause problems, but that's the opposite case from what you are describing.

The m03 RTR comes with an Am radio... To run it on the cheap, the FM radio + analog servo is the cheapest upgrade vs a 2.4ghz radio+ (digital or analog) servo.... The mini class should have stayed low cost....

Wait a minute here, were you telling me your RTR M03 is as light as my TA05 M-Four? If so, your scale is broken.

I do agree that you don't need to spend a whole lot to make your m-chassis fun to drive. But AM/FM radio, unless using PCM will glitch which is no fun. Radio is one thing I never go cheap on. Get the best you can afford with the proper receiver to match. Even back in the FM days I was using a JR R1 Pro with ZPCM receivers. Still not 100% reliable.

My m03 weighed 1086grams with heavy electronics and two huge capacitors... I could still lose another 30grams... It's all about thinking light... I added 218grams to my m03 to make 1300grams...
I also never had a glitch with my futaba 3pm FM radio.....

Wow, how did you achieve such low weight? Are you using aluminum bits because my electronics don't weigh much and still coming in at 1224g (includes body and battery). I suppose I can swap out the metal screws with aluminum or ti and swap the spur shaft with the hollow. Capacitors dont weight much of anything, no?

Your tamiya body is probably around 90grams, and your battery around 215grams. I run a blitz c30 body(0.5mm) 47grams, and a 2700mah TP lipo(168grams)... That's 90grams less on top of the 16grams servo weight difference... Add another 30grams for small electronics and no capacitors, and you could lose 146grams, and your car will weigh 1078grams.... No way to race tcs with such cheap upgrades...lol...

Bert, stop being silly. You can buy an M05 kit for under $150. If you paid $100 for an FM radio, you're a chump. Complete brushless setups can easily be had for less than $100 and you can pay anywhere from $16 to $40 for a set of S Grips.

Sometimes I think you're just being a troll. Might be you're just no good at shopping.

Cool, thanks for that.

I only run the Tamiya Rover Mini bodies so I guess I will never be super light. However, I should measure it with the lighter Lipo batteries, use tape to strap my battery instead of the battery tie down plastic and clips (M05 bits), and maybe do the screw swap to aluminum as well.

I did add 14g of weight on the front of my M03. It's a trick I've done since a long time ago, placing lead in the front bumper. I read Ivan does it too. This stabilizes the rear of the car while giving more bite up front.

Now I also put weight(14g)under my front bumper to make the 1300gram limit, but now my car is very bottom heavy, which is very good in corners...
I based my prices on top notch equipment prices... Sure , you can get everything cheaper with hobbywing, etc, but I have seen some super expensive minis out there competing, and they were on another level... I just don't try to catch them, and concentrate on having fun...
The TP pack does require some dremeling to fit though...

Personally I don't care about spending a few grand on my hobby if the investment has return and I am not wasting good money on something that is absolutely overkill for my application. Most of the stuff people use for racing, waaay overkill for my application.

So you dont see me bragging about misc bits, ESC or motor I run. I run kit ESC and only silver cans and just enjoy driving my cars.

I think some of these expensive mini drivers got their stuff through sponsorship deals etc... They are hard to match without sponsorship, and it's not a fair competition at all without handout equipment....I always run for fun... I know I have no chance under these conditions, and my mini is really a second car to double up the fun and kill time...

After trying practically everything, it has been (9551) for a while now the only servo I use in everything 10th scale. Never had one glitch or fail. Decent speed, light weight, low profile, durable, reliable, decent torque, reasonable price.

So much for TCS "rules", huh? Good to hear you're having fun though. That's what it's all about, this RC hobby.

Okay hprt- That's a lot of zero's you put on there. I shall try the S9551 on my M03 if my Savox dies. (I run S9452's on my modded-M05 and V2).
