I've been reading about what everyone has said about the TB05 Pro. I ordered one and it should be here by the end of the month. I currently have a TB04 Pro II that I have been racing. I raced it in GT3, then GT2 at one of the regional Tamiya races (with a 21.5T motor) and for the past two seasons in VTA at the local track during outdoor on road season. It is a stable car that is easy to drive. I've not had any difficulties with stripping gears; however, I'm running 21.5T or 25.5 T motors with gear ratios between 3.75-4.00. I shimmed the diffs per the instructions and have not had problems with the car. In the rear diff, I use a light coating of Cow RC grease, and the front diff has 3Racing Ultra High Viscosity Gear Diff Oil. I've been able to hold my own racing VTA, and have been improving as I race more (and practice using the simulator).

The big problems that I have had with the TB04 are that it is heavy, there are just too many moving parts in the drive train that lead to excess drag, and that the gear mesh is a pain to get just right when using the gears I'm using (50T pinion, 81T spur, 64P. It is not possible to see the gear mesh through the removal of the pinion gear guard because the spur gear sits so far back behind what is visible). I'm hoping the new one will have these issues improved.

I was curious to see what was similar to my current car and the new one. I found a copy of the manual, and made a parts comparison based upon both manuals. I'm sure I probably missed something in my comparison, but it should give you the gist of what is similar. I needed something to do - raining too hard here!

The new Roar TC minimum weight will be 1320grams.... So I guess you'll have to shed 120grams off your car...

I have the same weight. I used alloy screws and a 310g battery. I think it's a bit heavy, but not excessively.

Might try motor to rear and 4 deg hubs next time
play with your roll center adjustments. That plays into a large balance of getting the car right. Try 2 mm spacers in the inner links and 1.5 degree camber front and back. Your droop might be wrong too. Reduce rear droop and add front. Your car will be more stable.

Run another pack through yesterday, roll centres ok for now that will come later need to get it driveable first! Found the rear diff was dragging so that was re shimmed and fitted a front spool. the car was much better but had to drive aggressively on the throttle to stop oversteer, the back was fairly loose at mid corner but using old tyres so that doesnt help but too much rear flex could be the issue too. I think rear motor will be best suited to the track I run on due to grip but I like the car for the front motor position so will persevere with it

Private stash. I originally bought them in a RC shop in Poland, when i saw them. I think, they are one of the last one's in Europe.

What's the point of buying a TB05 and an infinite quantity of options instead of buy an Evo7 directly?
