I had some issues with the DasMicro Rx as well, my theory is that it's shock sensitive. Once it takes too many hits it will start going wonky. I reinforced the PCB by encasing it with hot glue and then mounted it using foam on all sides. So far no issues after that.

The pins on the Futaba were a pain, I struggled to unsolder then neatly.

The fully decased one I just soldered directly the the pin contacts on the board.

The cased one with the jst connections I just trimmed the pins and soldered the connections to the pins.

Unless I was on competitive racer I would just solder the JST connectors onto the pins and leave it cased or just replace the jst connectors with the typical Rx plugs as itís only 1.3g heavier plus on the GLR I prefer the wide upper deck so more available room for movement to get the balance right.

Also even when you decase the R334 itís still not small enough to go onto the chassis under the top deck.

All I can say is WOW.... Loving this car now! Just had to get used to the way it drives vs min z. Still trying tires on the rough side of the RCP track. We’ll be flipping it to the smooth side soon though. Right now the rear is loose on throttle, but very easy to drive still. May try loosening the ball diff a tad. Old track record was @ 4.287 with a stock mini z evo, now it’s a 4.014. And will be in the 3’s soon. Still don’t have the tires just right.

On another front, my dasmikro futaba receiver didn’t glitch once that I know of last night. Still going to convert a real futaba receiver anyway for my sanity.

We finally flipped the track to the smooth side and weíre definitely liking it. So far Iíve settled on ks type f ss for the rear and ks soft for the front. The rear seems pretty locked in on power and not as ďsquishyĒ feeling on power as the regular ks ss. Gonna try going from blue springs to purple springs in the front. Would love to use ks mediums in the front, but I traction roll with anything more firm than ks soft. Hoping stiffer springs up front will keep it from rolling. Super happy with the speed of this car. It was definitely a process getting it to this point. Last night ran a 3.8xx lap for a new track record. 😁 I appreciate all of the advice in this thread.

Seems like if Iím not pointed perfect down the straight any correction makes the car dart the way Iím turning the wheel. Iíve taken away close to all of the toe out in the front. Turned dual rate way down. Not sure about the servo saver. I built it carefully just like the manual says. Seems to function properly? Not really sure what to look for. Anyway, the car is a bullet with only a 3500kv Motor in it. Have the throttle epa at 75% and that makes it drivable on the small track I frequent. Waiting for KS super soft rear tires to come back in stock somewhere so I can try them. Running f type super softs on the rear now. Have -1* knuckles on the way also. More tuning on the way
I also feel super twichy too, I try to change the steering arm to be longer, please give it a try

I ended up cutting my end points way down, limiting the steering throw both directions. Night and day difference. Loving the car now. Itís so fast.

i think with the longer steering arm, will mechanicaly reduce the steering throw while add some resolution and precision

Worth a try. Hopefully it works out. I need to become a tire dealer. All these tires Iíve been buying lately.....

From your pictures, you have too much toe out. The car will be less twitchy with a little toe in. not much is needed

Default ESC

Having so much fun with my GLF I grabbed a GLR! Pretty simple build, and while much tuning still needed, Iím loving how it drives. Two questions here. The manual indicates taping the esc in place, yet the esc has mounting tabs and the chassis has countersunk holes to attach it with screws. I found some appropriate screws and attached it. Seems great, perfectly aligned with zero interference.
Second, anyone experimenting with 14mm rears and 11mm fronts?

Default Longer servo arm

Canít help chiming in on the longer arm topic. If you are all increasing the length of the arm on the servo itís going to do quite the opposite of what youíre expecting. It will increase, not decrease, mechanical throw requiring lower end point settings and ultimately reduce resolution. In a perfect world, at 100% epa you achieve, mechanically, the max throw you desire. Seldom achievable I know...

Well, maybe i was wrong in term of "long steering arm". What i mean is longer ball link connection on the steering crank.

Makes much more sense! My bad, didnít realize you were referring to the bell crank. Prolly should have looked closely at the pics.

Noticed the holes on the esc during my build, but with my off-road background I figured the tape would be flexible and not transfer as much force to the esc during crashes. Not that we are jumping them or anything, lol.

On another note, we just flipped our track to the smooth side a couple of weeks ago and have way to much traction. When the track starts taking rubber does it actually decrease traction some. I hope so. Friend is having a hard time with flipping at the end of the straight. My car rotates a lot and is easy to drive. We’ve changed front and side springs to red and that seemed to help. Would running -1* knuckles in the front help any? That’s really the only thing different on my car from where he started. He’s running the same tires as me also. My car is damn sweet to drive!
