CRC Gen X 10, World GT, Petit Lemans Edition, 2sLiPo 10.5
Setup Outdoor aphalt 160 foot straight
I had a good long workout with the car today. The setup was really good at the end of the session. We had low traction today because of high winds that blew the dust back onto the track. We had also a Darkside I-force on hand so I can discuss his tires as well.
I went with CRC spec Rears, BSR purple fronts. From previous experience I knew these would work well and they did. We also tried on the I-Force Lilac rear and Lilac front from Jaco; too much front traction, considerable spins. We went to Lilac Rears and purple fronts. There was not much improvement; I was surprised, but I have not run the Lilac rears. Next pink rears purple fronts from Jaco. This was the best on his car, but I believe those CRC spec Rears would have helped him.
We were both experienced pan car racers. We both thought the tiny 45 mm chord wing would not suit the outdoor track. I tried one just for sport. It failed on the sweeper. I could not keep the rear end under the car. We had a sufficiently long straight and enough motor power to get up to about 45 mph. I put one of my favorite JConcepts Illusion
wings on and the car was good on the sweeper now. I am afraid roar GT pancar rules had it right here, especially outdoors and not World GT.
I tried three gears starting with a 23/72. This worked out well. I got good speed using my normal throttle roll on for pans. I put on a 25 pinion. I got wild wheel spin later in the straight. I put on a 24 which was OK. None of these gears generated significant motor temperatures but traction was low, this limits motor temperature as well. Final gear 24/72
I added lead to reach 42 ounces (our Petit Lemans mimimum). I am sure this helped with traction today.
Ride height was 6 mm front middle and back. The car sagged a little and made contact in the middle with use. I raised the center up with the center shock. The front support of the shock had some longitudinal play in the mount. I tightened the bolt up tighter on the washers. I had one especially bumpy section coming out of the sweeper. I had to trim body aft of the tires to clear here. You must get your body off the ground for the best performance. Rubber and foam grip better than LEXAN.
-1.5 degree front camber

There are always some durability problems with any car.
GFR Body posts
. Finally I have given these a good test. This is what happens. Eventually your screw head or washer is going to pop into the body. All is not lost here. Now take the plastic part off which has a nice formed (pointed) top. Mark it for two holes for body pins. Enlarge or smooth out the hole in the body for a pass through type of body post, the normal kind.
What you are left with is a nice looking standard body post with the awsome microadjusting feature of the 1 inch long red aluminum sleeves. You can set that body post height exactly where you want it with the body on on the setup board.
This is what I thought would happen, but I had to try them. So take your chassis and body photographs with them new, and then modify them one by one as they fail or all at once which is what I will do sometime. I will still buy more just for the adjustable feature and the fact you will only ever have to drill two 1/16 inch holes in each post. Mark with X-acto deep, then drill.
The GenX-10 front axle takes 4-40 nuts which differ from other makes use of 5-40 nuts on the Aluminum axles. I lost a wheel on the track because I had the wrong nut on the car.
The Gen X 10 worked great and had superior forward and cornering traction today in bad conditions. The car runs too long on one pack with this powerplant and low traction. Maybe 20 minutes. I never dumped a pack. The car was sweet! I did not break it.
Ok here is the funny story.
So we are standing on the track, we have moats on both sides from construction. I put a long board at the sweeper end to keep out of the mud moat at the building. The driver stand is locked. Now I took reverse out of the car by intention two days ago but it did not take. So we start gabbing about tire sauce. I brake and stop to gab; I can't do both. After quite a while my finger goes off brake for a moment and then back on brake. Normally this does nothing on a race car, but on a Novak Havok you rocket at full throttle backwards. I was in the middle lane. Chris still driving is watching all this with alarm. I finally see my car jumping the mud berm on the side of the track spewing mud to the side and landing in the ditch full of water. It is not pretty. An then I see Chris's car flying full speed in the other direction nose first and he ends up in a moat full of water as well. His attention had strayed from his moving car by mine. We had stayed out of the moats all damn day and then we started to gab.
