LOL...

I'm in love with this thing. One control arm and a blown servo. Really need to learn to drive. At best the setup seems ok, felt way to soft and lacking steering. Prior to breaking the servo.. lol. I'm hooked. Busted up my DB-01 as well.

Let me guess, you broke it on that kink in the back straight? Run firmer springs, and put more weight in the front.

The actual broken arm happened right in front of the drivers stand. Same with the servo, then again repeated slams into the pipe will probably do that... Lol.

I thought I bought orange rears, and red fronts before I left. Turns out I bought orange AND red rear springs. I noobed. It's cool. I am gonna shift that battery further forward, had already thought about that. I ended up having the ESC set all sorts of wrong, friend of mine that came with helped me with that since my hotwire didn't want to connect..

​​​​​​I broke the Durga on the kink you mentioned, that's gonna be an eBay order.. ripped the front suspension mount right out of it. Hopefully I didn't trash the chassis.

I know it is expensive, but get a transponder so you can actually see if your driving is improving or if any tweaks will see a difference in the clock

Yes, get the two wire if you are ever going to go to different tracks because it is compatible with older decoders as well, not just the newest rc4.

Ron didn't have the system on while we where there. I'm a little more concerned with getting around efficiently without trying to break a pipe, the wall, or the driver stand with my car.

Do you mean the wire that goes directly to the phone?

He was talking about the transponder. You will want to get the hybrid so it is compatible with older timing systems. You do have the right idea. Practice on being consistent first. Speed and low lap times comes from consistency.

This is the two wire PT.

Oh ok. Kind of thought that's what he meant, was really unsure. Thank you for that.

I just don't want to show up there on a practice day and piss people off with my bad driving abilities. If it's my buddies it's a different story. They don't really care if I accidentally land on them, or bump them off, I know I don't. A complete stranger, however, may want to give me an earful. Not a chance I want to take.

Sorry about the unclearness. Transponders are very overpriced but still a must have. I would try to find the transponder on sale for 115. You can use amain coupons to buy it I belive.

People should not get angry at you on practice day unless you are the direct cause of their cars breaking. I know you have tunnel vision right now because you are new, but over time, your field of view will widen and you can see someone hauling ass behind you and you just let them pass in a open spot.

Tunnel vision hard... "Moved" my buddies B5M right off the track with the DB-01 at least once... Couldn't catch him with the RB6.6 unless it was mid turn.

For the guys that runs the 6.6 on turf how does this car compare to others? I currently have the losi 22 4.0 and am thinking about changing. Any tips or info would be appreciated.

I have never driven a 22. I have driven a b6 and b6.1, compared to the b6 the rb6.6 is alot reactive and fast response in direction change. The b6 is more planted in the corners and lazier. When I swapped to the rb7 gullwing arms, it lost it's edge in handling for more stability. The b6.1 is a different story. That thing has steering for days. It is stable and has a ridiculous amount of steering. Can do the entire track barely turning the steering wheel 1/4 way. The b6.1 definitely felt better. Compared to b6, the b6 feels easier to drive while the rb6.6 felt faster.
