Would prefer a mix of both.
Would be --->

this is a long thread... and I'm sorry if I'm repeating a question...

But before I start the build on an R4, is there anything I should purchase and install right off the bat?

Thanks... when I build this thing, I would like to just get it done the first time.

Thank you

Like Nikoscar said. I would prefer a mix of both...... But if I had to get R4 I would wait for awhile!!

My choice would prob be
Cap
Xray
shimo with xray diff mod n a cap clutch!! Would b a killer!!
Mug
Serp
Shep
R4
G4!
Ntc3
hpi rs4 pro2! So the ntc3 wouldn't b last!!

The Ntc3 is last , come on man ..... it's a legend...lol...

Ofcourse I will choose V-one R4... I switch from Xray to Kyosho and my lap times improve a lot...(1.5 sec by lap!!!)...I won 2 stages from national championships, and make the TQ an de Best lap of all the tracks of the nats!!!...
But...If you are noob... choose a Shimo used...if you are more experienced...R4 rules!!!...

Step 1 - VZ403HB Hard diff cases.
Step 2 - Aluminum servo horn of your choice.
Step 3 - Assemble?????????
Step 4 - Run it!

Test

Wow.. congrats! Any setup to share?

I'm not callin you a liar, but I'm willing to bet that there was something def wrong with ur xray if u picked up 1.5sec a lap!!! Thts alot! Thts like D main to the A main! I haven't witnessed those type of gains at our track! Ive heard from X RRR drivers tht the car turns better but it hasn't showed yet in lap times..... But if thts wht the R4 has done for u I would def stick with it.....

Thanks for the help... I'll definitely pick-up those diff parts at the same time with kit.

I'm not a noob but I'm no expert, just getting back into the 1/10 scale game.

Or gaining 4/10th per lap right off the bat with the " Sauce " !!

Jajajjaa... With my NT1 I pick the first place...I swithed from Serpent 720 to NT1...but the Xray allways loose the middle belt teeths...I fixed it with alternative belts... those from zepping...And I started to win...Then a group of the better drivers that had been with Kyosho from a lot of time, RRR, FW05R, etc etc... the told me about the R4...So I told to my parents and they gave to my as a birthday present...I start to run and in the Nats I destroyed the lap record (that I had record with my NT1) and made the TQ and first place again...xD....
I`m very happy (crazy) with this car!!! and the results that I had reached!!!..and it's very sad for me that you had a lot of problems with R4...
So... they only objetive thing that I can say is that the cars is really fast...!!!...I was fast with Xray too (first time that I picked up I got the 1rst place in nats too, and the track lap record)...but R4 is faster....for sure...xD
Here are 3 R4, running... one of those had broke diffs two times...

Setup...Its similar to Shimo's Setup... some a little changes..
Consider that my track has medium-low grip, very dry and a little bit bumpy.
Front/Rear:
Shock oil: 400 kyosho/400 kyosho
Spring: Serpent Red New generation/Serpent Red New Generation
Shock Position: B/E
Caster: Spacer 1mm
Camber: 2º left-right/ 3º left-right
Toe: -1.5º / 3º
Width: 198mm/ 200mm
Downstop: -3 / 2 (measured with tool)
Antiroll: flat / Standar
Tire: Enneti sh37/ Enneti sh40
Tire Diameter: 62mm /63 mm
Chasis Height: 7 / 8
Front Diff Oil: 50% 300.000 Kyosho + 50% 500.000 Dynamite
Rear Diff Oil: 60% 50.000 Kyosho + 40% 125.000 Losi
Note: Not filled to the top...Rear diff feels like 90%... aprox...
Wheel Spacer: 0mm/ 1mm
Upper arm Position: B
Body: Protoform P56-N

Thats the important I think... the others setups are like the Shimo setup...
The car fill a little understeering in the middle and corner exit with gas... I will like to improve that...
Some recomendation¿?...
Regards...xD

does anyone have the weight of the r4 front and rear diffs?

Anyone know if there is an aftermarket alu servo horn for the steering?

Thanks.
