I have done some work on getting a longer motor fitted to my GTe
I looked at the steering pivots and saw they were leaning backwards at an angle due to the steering rack mount (600167) being machined at an angle
I removed the Steering rack mount and turned it upside down and refitted the pivots , This caused the arms to sit 90' with the chassis I can now fit a motor with a 74mm length with about 3mm clearance still Some minor shaving of some plastic was needed. I also had to redrill the 2 holes on the top mount for the screws going into the top of the pivots

I use 2 x 3c packs. It can be hard to find ones that fit. I'm using some zippy packs and had to raise the battery doors with body mount extensions to make them work. I find 5000mah packs get me through a 7 min race. If your not racing and just playing they would last 15-20 min depending how you drive.

If your not thinking of racing I would look for something in the range of 7000 mah 2s. Don't worry to much about c rating as long as it's in the 40 range. They will give you about the same run time as above. Take a look at hobbyking. If your want to race my suggestion might be more specific and would point you to something higher price then hobby king packs.

If your new to racing the stock motor will work fine for you initially. You may want to get a sensored set up if you decide you like it.

If your racing look at what other folks have that work for them. We had a few stock setups come to our track and they were fine. The problem I've seen is with folks melting the small bullet connectors in the battery packs and then melting esc's (I think a weak bec might be the culprit?).

Thought I would bump the thread and give some info on our racing here in UT

We have had a pretty good group of Nitro GT racers here in Ut for several years. After I started taking over as race director I did not have the time to keep my Nitro GT running where I wanted and quit racing to run the race program.

This year another racer decided to go against the grain and built a Serpent GTe Kit to race....... I thought this was my chance to maybe get some race time again and decided grab one as well. He built a team kit and I bought a new RTR roller from a chop shop online.

Mine was the RTR chassis so I went thru the chassis and used lock-tite and just double checked the build which was pretty good for RTR standards. I installed the Hobbywing M5B combo with the Xerun 150a ESC and 4038SD 2250kv motor. I am running 2-2s 7200 SMC lipo's. I had a Savox servo laying around so I threw that in.

On the first race night my car was loose in the rear end, Ty one of our local Serpent Drivers came over and set my front droop and raised my roll center. The car felt better but still loose in the rear I was running sweep 50's and it was pretty cool nigh in the high 50 to low 60's F..... so Ty threw a set of his Sweep 45's on the back and the car was hooked up. I was running an 18t pinion and on our track the car was very very quick and quite a handful. I decided to step down to a 16t pinion until I get more familiar with the car then will work my way back up. Even at the 16t pinion I have no lack in top end and can still pace the faster modded nitro cars or slightly gain ground on the more standard powered nitro cars on the straight away.

My car is still running the box stock diff oil, shock oil and all the factory adjustment besides the droop and roll center and the car has felt very good. I know many people who put down RTR kits but mine has been great even Ty and the other GTe driver felt my car handled very well. Not bad for a RTR car that cost me under $500 to get on the track, I'm into the car $255 for the roller $210 for the Hobbywing Combo. I am curious to see how a full RTR Serpent GTe would handle since I have made so few changes to setup.

With 3 race nights under my belt so far my lack of drive time over the last 3 years as race director is really showing. Hopefully I can get enough drive time to do the car justice.

I am excited to see more guys looking at joining our GT racing program... I think historically many racers have been hesitant to grab a nitro GT and I am betting on some of these guys may feel more comfortable grabbing a GTe and with some luck our GT program will continue to grow.

Selling my Cobra GTe car. Had a lot of fun racing it last summer, but the track I ran it at, covered the asphalt track with dirt for oval/offroad, so there's nowhere around to run it anymore. FS Serpent Cobra GTe GT8 car

Does anybody have a good setup for running the Cobra GT-e on asphalt?

I checked on Petitrc.com Setup sheet database and couldn't find any Cobra GT-e setups.
