the question is where do the Ho Bao mesh in with xray springs? I was told that silver was stiffer than gray and this weekend I ran the gray/blue and I can't tell if they are stiffer than the Ho Bao grays?

1800kv that motor is huge have you try it yet? I had it now for a long time brand new in the box but I thought it was for a truggy.

i think they are close hobao grays to xray gray blues that is...dont know for sure ...but i do know less coils eqauls faster/smoother response in 2 identical rated springs

now if ghea would make some pistons for the 9 ...nothing wrong with stockers just like to tinker on set-ups

This has nothing to do with acceleration. If Ofna was smart, they would have gone to a 4.3:1 ratio in the 9E and they would have fixed some of the gearing issues.

With the same equipment onboard, my 9E and RC8E weigh the same. My Losi is a tank.

Not a fair comparison. Your RC8E has composite shocks and other stuff that the Losi doesnt.

Default carbon fiber shaft just broke.

I have already tried it and works awesome,Smoother than my 2200kv and get longer runtime by 2-4 minutes determining how you drive.Runs around 143-151 but never climbs above that because i have the car geared 16,40.Here are some pics of the shaft.

My RC8 is a converted Team car so it has metal shocks.

what gearing issues ?
In order to correctly gear my Tekin 2050 I had to grind a divot in the side of the motor for the diff cup. Had the internal ratio been 4.3 or had the spur been bigger, I could have used a bigger pinion. I have since corrected the problem by retrofitting a Losi 43t plastic spur. I should mention that we run 15 minute mains so I probably need to gear slower than most people for run time and temperature reasons.

Default same here

I had to grind 2 fins off the motor to run a 16t pinion on the stock 40t spur.

To get the correct gearing, I needed to run a 13 pinion on the stock 40 spur. Works fine with 36mm motors, not so good with 42mm motors. Now I can run 43/14 and there is more clearance for the same ratio.

not trying to me a smartarse but thats a clearance issue not a gearing issue .....car was designed for a 36mm motor not a 42mm ...i also run a tekin 1900 combo 14t pinion is tight but 15t works great dont need all that timing anyway temps 150 12min main

2050 should be fine with stock gearing 14t pinion and timing not cranked all the way up ?

Well ordered a 1400kv Tekin. So going 6s + 1400kv + MMM for now. Next on the list is a MMP.

Could not stand the wait of 8-10weeks for a motor from Neu.

Does the Elite-RC mount eliminate the issues people are having with fitting spurs and pinons?

All i did was flare out wide enough the electrical eyelet where you crimp wire into it so you can crimp with pliers the wire rod in it, then i soldered the wire rod to the eyelet so it wont come out and then added heatshrink to the wire rod so nothing shorts. Then all you need to do after is find a location to place the rod with eyelet on it undo the screw and screw the rod to the chassi and bend the rod to what ever shape and etc as desired.

Here are some pics
Nice detail shano. your Hyper 9e looks sweet. I'm glad your carbon fiber chassis has improved the performance of your buggy. and it looks awesome.
I was just talking to a Pro sponsored racer today and showing him my buggy. I told him my carbon fiber chassis was almost half the weight of the stock aluminum chassis, and also has more flex than the aluminum chassis. His Jaw dropped and he grabbed my buggy from me and said, " Lighter and More Flex". It was awesome to see that kind of response from a pro racer. Unfortunately for the Pro's that have full sponsorships, They can only run the equipment they're sponsores say they can run. At least that's my understanding of how it works. It's what I've been told in the past about being fully sponsored.

This Matrix Chassis is awesome kman. You're going to love it :-)

I can't believe you broke the custom made carbon fiber shaft. Erik will want to know this broke. you should email or call him as soon as you can. This means Erik will have to design these carbon fiber shafts even stronger. I see it broke where the Stock Aluminum Shaft(donor part)connects to the carbon fiber cylinder. I understand Erik to use Epoxy and a Pin driven through both, binding them together. It's incredible you broke this shaft. I believe snrscion's is still going strong. But snrscion didn't pin his. only JB Weld and a Screw connecting the two parts(Universal to Carbon fiber Cyliner), If I recal the pictures correctly.
