So Kyosho America told me that they will not import the R4 SP into the states. I try to support Kyosho because I like their product but they are making difficult to do so.

I have not yet build my R4 car kit, I'm still looking for which engine I should pick up.....What do you you guys think about the OS Max 12 TZ T5 port turbo? I'm concern the flywheel come with the R4 kit will it fit the OS Max 12 engine? Thx!

5 port isn't illegal¿?....
I think that Nova PTS or Team Orion Alpha ABI is the best of the best...Orion fits perfectly in R4....a lot of power...excelent quality materials... easy to perform to the top!!....

Tomas, 5p engines are not legal on ROAR/IFMAR sanctioned events, for club racing or open events they are fine ...

I can't find any my LHS in Toronto carry Orion Alpha ABI, the one that carry Orion is .12 wasp..they have issue on this engine so forget about it.
What do you guys think about OS TZ 5 port on R4?

Last week Champion in lower final ( C main ) and i'm the only Kyosho R4 there Didn't manage to bump up due to driving mistake. The car is alot flatter and stable even it is too light. With 2 low profile servo the car was 1708g and i'm added 25g weight to pass the weight control.

Further i need more sensitive steering to catchup those A main lap time. They are crazy fast..

More sensitive steering.? Or just more steering?

Hey guys I have a question.
The Ackerman is connected to the servo saver.
I notice that the upper deck has two position noched in it.
My question is. By moving the servo saver front or Back.
What type of effect does this cause to the steering
Of the car?

nice question,i am also want to know anybody ?
thanks

Moving the Ackerman back , that is less Ackerman . With more or less Ackerman that affects how much more the inside wheel turns in relation to the outside wheel. So less Ackerman will make the inside and outside tire turn more evenly.

Why? Does the rear of the car like to come around and meet the front in on power situations on corner exit?

I notice there is No pump function on the gas tank? Can you guys tell me how to pump the gas in to the engine? Thanks!
