Had a great days racing today with the Photon. The car just gets better and better. Managed pole in the B final, a result for me and also a PB to boot.
My car is pretty much kit set up apart from HPI pro4 blues all round. I have plenty of grip in the corners but would just like more steering on the tighter slower sections of track. Does anyone have any ideas what I could change to achieve this ?

is steering travel limited by the steering block arm hitting the castor block, the bellcrank hitting the bulkhead or is it at the servo?

which akerman insert are you using and which slot on the bellcrank?

With running the gear diff up front is it recommended to run the steel dogbones or are alloy ok?

It's 31.5mm between outer edge of the bearings.

Im running alloy with no problems at all, with the gear diff in the front the cvd's will last alot longer than using a spool

He said felt like a front one-way.

I am using insert 10 on the centre position. Even if let it move all the way to the castor blocks it dosent seem to give me as good steering as my scythe at low speeds. And then also makes it to twitchy.

It actually makes it like a spool but, there is some give that takes away some of the wheel slip.

Running a one-way gives you no front brakes and this setup does not do that.

I got to the track on saturday and tested my gear diffs. Track is Jackson RC in NJ, Med grip unsealed sprayed asphalt. I had 2 cars running, the "slow" car is 17.5 no timing no boost, duo 1 middle hole 3.5FDR. The other car is 17.5 open, 208, etc.

So I stared with the slow car with a front gear diff and rear ball diff, I had put 50k in the front as it was all that I had. This car was a bit loose with a 13.5 in it, but now with the slower motor and diff it had amazing turn in, but had the expected on power push. I then put the other gear diff in the rear which had 5k in it. This setup was good, but I had a lot of trouble getting around the sweeper. With practice almost done, I put the spool back up front, got the sweeper back, but got a push on the slower speed corners. I went with this setup for the rest of the day. I am going to try the front again with some thicker fluid, I think with the small gears and only 2 spiders its going to be hard to really lock up this diff, there just isn't alot of surface area.

I had put the rear diff in the fast car to start, my car is generally loose at this track in the beginning of the day, and now it was 5x worse. I tried to plant it, and it was good most of the time, but I found myself every once in a while either getting a wheel up on a curb and looping the car, or powering too hard out of a corner and fishtailing, so I just put my ball diff back in for the day. I meant to test it after racing at night where the car was really planted, but I forgot.

I think I will be running it for sure on carpet, and it may end up being something I can run at night outdoors, we'll see, unfortunately its a long trip to the track to test too many variations and setups.
