Jim,

Will be better when the other big bore springs are released. I am still running my MI4LP, fitted with the Tamiya TRF shocks and HPI springs. I used silver springs front and rear.

The car works Ok to me, managed to win the 21.5 TC class at Kambah. Only thing when the grip came up was to add a 1mm spacer on the front hub, to stop the car from traction rolling, especially when using tyres that were used for a few runs. On new tyres it was not an issue.

I ran the LRP SXX SS V2 ESC with a LRP X11 21.5 motor. I had a FDR of approx 4 and a rollout of approx 50mm. Next time I would turn down the boost and increase the FDR and lower the rollout to approx 40mm.

I will have to get off my butt and build a CX and test the car out. From what I have read on this thread it is better than the LP. The only problem I ever had with the LP was breaking the hinge pin holders, which I changed to alloy and only run 2 degrees rear toe. That certainly asisted with settling down the rear end and making the car faster and having less push.

Later,

Calvin.

Some of the fit and finish on the plastics is to be desired but other than that im a happy camper with a big plus next to the Diff on the Cx as its freakin awesome compared to any other diff ive built. I will be updating to the alloy pivot blocks next as im sick to death of the plastic ones. This is one area where Xray wins hands down and makes changes at the track easier as ive found the Schuie plastics to bind up a lot. Although im still searching for the best set up on my CX and ive got near 2 years under my belt with My T3 they do near identical lap times. But i can drive the CX much more consistently over 5 minutes so im hoping i can get some more speed out of it and take it to the next level.

skypilot,

Yes. Boosted 21.5. We have to run two door bodies, so the NSX, 350Z, Porsche, etc and no protoform TC bodies.

I used the recommendations in the LRP Instructions for 17.5 and adjusted from there. Motor was 67C or 157F after six minutes of racing including two warm up laps on a largish track. Laptimes were 16 sec plus.

Regards,

Calvin

With the Smokem link paltes on you certainly get more adjustment

The dual steering seems of little difference to me, overall the car is quite pleasing...might keep it for a while

Hi Stefan,
as car was designed on tarmac I guess it should be good out of the box with just minor tuning to your needs.

Its been awhile since I have been on the forum. Ive been searching for the front a arms (standard med flex and graphite) for the mi4, it seems that they dont make them any more. All I see is the short ones or the extra flex standard arms. Which ones should I use and what is the difference between the short and long a arms, how does it change the cars handling and what are the pros and cons. Any help would thankful.

You can use the short arms, just add 1mm washer against the pivot block to retail the same overall width.

Thanks in advance.
