I got my DR-1 chassis today and it looks pretty good to me at this point. It has what feels like pretty solid poly motor magnets, 6ohm armature, 7t pinion, 25t crown, and rear tires .510. Neo traction magnets are enclosed in a plastic sleeve that is part of the chassis. The bottom could definitely opened up for more downforce if needed. We all know where this will be headed  ......the extra downforce will be needed. I'm not a big inline guy but that's only because I haven't spent a bunch of time on them. I am looking forward to playing with this one. I am not looking to compare this to the 4 gear chassis because that is like comparing apples to oranges. And I hope this does not turn into a 4 gear bashing party. I personally have had some pretty good luck with the 4 gear and am fond of them. They are another style of chassis that is different like the Tjet or the MT are. I will be comparing the DR-1 to the other stock inline chassis. |

Mine arrived today also with the DR version placed on back order. Looks like it has a lot of possibilities and will be a fine addition to the current lineup of inlines. It will make using a 4G size body easier to use but we have been using the other inlines with no problems with a 4G body. Just a little more work to add the front axle!  Alan |

My DR-1 chassis showed up today also. I did a little testing on it and like the way it runs. Right out of the package on my track (15'2" @ 13.8v) it ran 920's with the front end hopping just a little. The pickup shoes were just making contact on the leading edge so I tweaked them a little to get full contact. I added a little lead to the front of the chassis and dropped down to consistant .870's with a best pass of .862. All passes were run with an AW Prostock body. I believe it would be even quicker with different gearing. With the stock 7/25 gears, the car tops out well before the finish line. I really like this new chassis and I plan to buy more of them.

I am sure the performance of these chassis will be very similar to the TR3 chassis which I did a report on. If enough of us are interested we can set up a class for them along with the DRs. I like the chassis and think it has possibilities. I also saw that they topped out at about mid track so a different gear ratio is needed and I ran them at 20 volts. Braid was a huge boost for these chassis telling me that shoe contact can be improved.

I am excited about this chassis I am sure the folks that I sell custom 4-Gear type cars to would love to have an option for a faster chassis with their cars I have ordered more and will offer them on some of my customs.

Looks promising for new in liners, an new class(es) being thought of??

Got mine today. Overall looks pretty nice. One of the pick up shoes is deformed, like it got twisted when it was separated from the rest of the material. The pick up shoes don't look like they'll interchange with anything I have.
Somebody mentioned that the DR1 might benefit from some gearing changes. Its a pretty close fit. There doesn't look like enough room to go bigger on the crown gear. Of course a smaller crown and pinion changes are still an option.
Looks like it will clip into the newer AW bodies as well as screw mount in the Aurora bodies. Nice!

Sounds good. I am waiting for both chassis to be available so I can order both.

I got the opportunity to do a little tuning and make a few passes down the track with the DR-1 I got. Car was in pretty good shape as I received it. I did have to do some work on the pick ups. There is not a lot of contact patch and there were dents on both. I was able to get them flat again. I also did some cleaning on the brush tube end. I started testing at 20v on a clean track and running a stock AW Robert Height Mustang funny car body. Car does not have enough downforce in the stock configuration @ 20v. It would deslot every time. I wanted to see what the car would do at 20v so I stayed with it and added a set of wheelie bars from my Super Comp car. With that set up the car ran a best ET of .7296 (60ft .1110). Wheelspin off the line is pretty bad, but car stays in slot every run. I added a small traction magnet on the left side just to see what more downforce would do. The car almost made it into the .6's running a best ET .7032 (60FT .8590). Once the car has a good break in and more tuning it should make it into the .6's. Any of the modifications that I did would be outside of a Stock Class or run as Stock. Voltage might have to be considered to run chassis "as is". With that in mind I ran it at 18v and removed the extra traction magnet but I did not take the wheelie bars off. The ET went up (.7970) as expected and the 60ft was still lower than at 20v (.0990). So that definitely helps get the car get launched without as much problem, but when I pulled the wheelie bars off the car either stuttered very badly or deslotted. That's where I'm at with the chassis after preliminary testing. I look forward to seeing what some of you Inline Guru's can do. I want to get the car down the track at at least 18v without adding bars or magnets. I will try some weight next and maybe some work with the pick up springs?? Here's how I ran the car.   |

I am really surprised that the car did not 60' well. With the 2 TR chassis I tested the 60' time was excellent, hitting in the .05s. They also had no problem staying in the groove. Must have something to do with the larger rear tires. I found that the TRs flattened out about mid track until I added braid.
What kind of speeds did you get out of it Jeff. Mine both hit 14 mph dead stock.

Well did a little testing today on the DR1 chassis. From the box to the track 1.290, pretty darn slow for an inline. I ordered 3 so I ran another one and it ran an .832et, not bad. All runs were at 20volts. So I decided to work on the slow one. The pickups were a mess nasty edges and did not lay flat. So I filed off the edges and tweaked them for better contact. Best run was a .732et. Then I put a body on and it would not go down the track. So I glued one traction dot magnet to the chassis .703et with no body. Than a second traction dot magnet for a .692et. Then I added braid to the pickup shoes .603et. Next up 8 tooth pinion, bang .575et. I really like this chassis, lots of potential.

All sounds great. Any body try slamming bodies? What is the ohm rating of the motor and the overall length of the shaft? Based on the brush set up you can not run a Tomy AFX motor. All other types should work. Tyco,LL,Mega G, Super III, Wizzared,etc.

I'm really surprised the neo t-magnets don't have enough down fore to launch the car with out wheel spin. What diameter tire is on the car? Try a smaller tire for the heck of it. |

......the extra downforce will be needed. I'm not a big inline guy but that's only because I haven't spent a bunch of time on them. I am looking forward to playing with this one.
