I am really debating if I will keep the RB6. It is hands down the best buggy I have owned. Good quality and best driving. The only things I dislike are the silly parts trees, tight electronics mounting and the ugly bodies. I talked to a few local hobby shops here and they dont carry or plan to carry rb6 parts. So I guess I will just run both buggies this weekend indoor and outdoors, and the looser gets sold.

yeah, my wife says I have RC ADD. I have changed my mind about which buggy to sell like 20 times this week. The RB6 was so much nicer to drive then my B4, but AE has been pretty good to me over the years. Its not like i will ever go pro or get sponsored. I am a weekend warrior and the rb6 is like driving a Ferrari as a daily driver, seems like a waist, lol. I will admit though that the RB6 is probably the best buggy on the market. As much as I like AE, I am not blind like others (Wild Cherry), lol.

I bought a B4.1 WC and added big bores, alum rack, vts, etc etc, and although nothing "broke" on it, it required parts constantly to keep the slop down, even the diff only lasted half as long as the K car. The FEW things that you need to keep as spares maybe a bit more, but its worth it. Would you show up to daytona with a camry because you're ferrari costs to much in gas to race??

A fellow racer tried to use proline B4 rims and they didn't work, the rears I believe were close, but the front hex depth was way too much and really bound up.

I have yet to race a rb6 as its not here yet, But the b4.1 out of the box IS the best car i have ever driven. The rb5 was really good but super fragile. the durango i could just never get to feel right. the losi jumped well,thats where it ends. I always fall back on the good old sloppy, clapped out b4.1. Hope the rb6 is different. my .02 cents

Yeah, I know Mike. Its loyalty vs performance. lol. I like the b4 but it lacks the stability and plushness of the rb6. And I just dont think i could ever tune that in. Its like the things wrong with the tlr22, you can adjust it a little, but you wont be able to drastically change the nature of the beast. The RB6 is just so freaking easy to drive. I sense my poor b4 may lose and be sent off to the for sale thread . Same thing happened in 88'. I had a rc10, but i traded my skate board for a Kyosho Ultima. I like so many things about the ultima. But eventually picked the RC10 for sentimental reasons.

I am not too worried about broken parts. mainly just the hangers and maybe the rear camber block. I figure I will need to drop another 75-100 into the buggy if i keep it. But I will keep the buggy that is the most "fun" to drive, lap times be damned.

If you're OCD, (like me) especially about wiring and electronics layout, NOTHING will satisfy your OCD like the RB6 can. You just can't do this with a B4. So to use that as an excuse is flat backwards.

I agree with everything you just said. After having driven the rb6, I didnt even feel the need to tune it. In that sense its just like the b4, out of the box it works great. It was noticalby better at high speed on a bumpier surface. The suspension really soaks up the bumps. And it still has pack on the jumps. The only real issue I ever had with the b4 is that I had to constantly make small corrections because it would start to feel unstable at higher speeds. I had to make dramatically less corrections with the RB6. People say the Kyosho springs are a lot more plush. I might put them on the b4 just to see. I would suggest a shorty though, as electronics are a bit tight and the buggy seems to really feel good with it. Like the b4, I was able to change track and simply swap tires. Didnt require any setup changes or chasing. It turns on a dime, while maintaining a good balance of front to rear traction.
