Gotta love the BD.

Tough choice for me, LCG or BD?

Im thinking the LCG will be the better choice as im only racing stock at the moment, and perhaps some 19t in 6 months or so.. Any thoughts guys?

Either way you should be fast, but I think the performance of the BD will be better should you step up to more powerful motors.

Hi

If you race stock I would go for the LCG its the perfect choice!

I wonder if the cornering speed will be as good as the BD?

All the shaft cars Ive driven seem to lack in cornerspeed compared to belts, but they have more rip out of the corners to make up for it.

well, maybe the LCG will be a bit better because of its low center of gravity but you re right about belt cars though...

The LCG is still the best choice for stock I think

I agree with you about it being the best choice for stock, but I also know the BD drivetrain can be made super free, both can be contenders in stock.

But wouldnt you need ceramic bearings to free it ut? you will never make a BD drivtrain spin forever like a shaft car but I guess that doesnt mean its not efficient

Which one do you thinnk you will be getting?

Has anyone one notice how the MR4TC-BD makes Tamiyas look PALE

nice to hear... another satisfied racer...

i ran the car in 3 different tracks, on 3 different days, 23turn, modified and 19turn, didn't change a thing and the car won each time out... also the tracks were all different in nature, from a very big bumpy nitro track, to a very tight high traction track, to a meduim sized flowing slippery track...

definitely,this car is dialed !!!!!

you would be suprised how free the BD is i raced it in stock yesterday & it was ballistic on the straights & through the middle. i don't care wich car it is anything thats got a shaft in it has always had probs, you only have to look around at my local club & there always shiming the front bevel gear.

I agree but once you ve shimmed it properly it should be fine though

Do you think the BD has more free drivetrain than the other main belt chassis? like the 415, Fk 05 and RDX?

This could come from the design of the bulkheads and how the belts perform

Hi all,

Had my first meet with the BD yesterday and i was very impressed. I raced at a new track with only a 2 minute practice run to get the car bedded in and get a feel for her.
After 3 rounds i qualified 2nd (1 second off TQ) and in the 3 legged A finals (best 2 to count) i finished 1st, 2nd and 1st to take the win overall. Some very good racing in the last leg.
Anyway imprssions of the car....I was initially worried at the amount of flex the car had when holding the front and rear of the car and twisting it, but it seemed to give up plently of grip without any loss of feel or sharpness through corners. It was very stable and smooth, had alot of grip and was very easy to drive...thumbs up!
I used several options on the car...
Composite spool
Locked centre pully
Ti Screw kit
Yokomo composite shocks (from the old MR4 TC Range)
Yokomo SD Graphite suspension parts
Square Ti axles front and Rear
Yokomo Alu dogbones Front and Rear.
I had a bit of a shock when i put her on the scales as i had to add 125g

Chris

ps - Nice to meet you yesterday Dan!

Hi,

I was suprised to hear that the BD had some flex issues, at first you would think that yokomo would make a really stiff car as they already have the SDs with different stiffness for asphalt but I m sure the Yokomo engineers did not leave that amount of flex if they knew it could be harmful

Flex and especially torsion flex can help to get more grip, even on carpet and yokomo is trying to take advantage of that IMO

Sorry if I bored everyone!

See ya

I can make a very free BD drivetrain with the stock bearings, just tricks like soaking the belts and spraying out the bearings work wonders. It will never spin like a shaft, but that doesnt mean it's going to bog you down coming out of a corner.

I'll propably get a shaft car just to try it out, but I will be running the BD since all I race is mod.

They arent flex issues at all, if the car had a really stiff chassis it would be a bit harder to drive. This car has a perfect amount of flex for asphault racing IMO, and that is what makes it so easy to drive.

Thanks
