I have not really had any time recently to write anything. However have been busy learning new things, I have bought a couple of new cars, have been trying out different speedo/motor combinations and have been regularly racing at my local track. All of those things would have been very beneficial for readers here.. so will be sure to post some progress reports soon!

Just have not had enough time to write here lately, however have been working on a bunch of new things. I have temporarily retired the Ta05 , due to transitioning to a new car. The Ta05 is well and alive, just recently installed a front spool in the car, however waiting on a new SPX controller and 17.5 motor combo to get it going again.
In the mean time I have continued to race a used XRAY T2R-PRO that I picked up from a friend at my home track in Gaithersburg, MD. The car has been performing very very well, and I have been learning a lot about setting up cars and most importantly how to drive them on a track in race conditions.
I will be posting pictures and setup details and more information very soon! hope everyone enjoyed thanks giving break 
I have no real pictures to post, only that few of the top racers here in the area saw the actual car at the nationals in frederick, md.
Hope fully will post pictures as soon as I get my hands on either the car or the pictures.

So the effort continues to tame the Ta05 to be able to race competitively in the 17.5 class with experiended drivers and along side high end cars such as the xray, hot bodies etc. I have made several changes since I last wrote, but a summary of them are as follows
- Changed speed control from LRP SXX TC to LRP SPX Competition (better programming for stock motors)
- Changed to 64p gearing so it is possible to gear more accurately
- Added 3Racing trun buckles throughout the car replaced the stock as they are hard to work with
- Changed the suspension oil to 60 wt for front to add more steering, rear is still 45 and using TC5 blue 17lb springs all around
- Gearing is currently at 64p 88 Spur and 47 Pinion with FDR at 4.2
The car has been running very well and it is truely a pleasure to run this plastic chassis, the additional hop-ups have definitly made improvements and I am only focusing on minimizing additions of hop-ups unless I really need them so not much visual changes.
I will be posting more details of setup and pictures soon so stay tuned, as last weekend the front differential arm broke due to added pressure of increase drag brake that I needed. I am currently looking into using a solid front axel instead of a differantial to increase lap times and overall performance for a medium to small size technical track.
Speed Passion 17.5 motor
Something to note about speed passion motors, they are outstanding quality and very high performance. However something to note is that they usually need to be geared very differenlty than other motors to take full advantage of them.
For example Novak 17.5 motor is recommended to be used with 3.5 FDR, speed passion is similar in the sense that the v2 motor like the novak does not have physical timing. So in order to get most of the speed passion motor, i will be testing it with higher FDR in the range of 4.6 -> 5.5 plus with increased timing on the LRP SPX profile 8 to gain maximum torque and top end speed.
More to come….

I am currently working on fine tuning the Tamiya TA05 chassis to prepare for racing in the 17.5 class at the www.rctrack.com The Track in Gaithersburg MD.
Currently the following are the specs for the car
- LRP SXX TC Speed Control, Power Profile 8
- Speed Passion 17.5 Brushless Motor
- 48p 78/38 Spur and Pinion
- Optional Tamiya drive belts
- Integy drive shafts
- HPI tires (Pro Compound)
- Ferrari F430 Body
- Spektrum RX/TX
- Trakpower 4900 mah 25C lipo
- TRF shocks and TC5 17lbs springs
The car so far handles really well on asphalt track in gaithursburg md, my fastest laptime on the track is 16.5 seconds. The average for most drivers seems to be around 17-20 seconds, I intend to further tune the car and post results if I am able to further reduce lap times

It has been a while since I have written but have been busy with work and other projects including setting up HD for video production and setting up and building the Tamiya F104 pro (stay tuned).
I have to say the HPI Sprint 2 RTR is an amazing RTR package, the car is well built and handles well on the track. For a RTR it is hard to find kits that are so competitively priced and can run as well as this chassis, I have really enjoyed doing the brushless conversion and testing the car.
The mamba max system was chosen and used the 5700kv motor for now, the only thing other than the brushless system I used is a Robinson Racing 48p 22t pinion, everything else is bone stock on the car and it runs very well.
I am using Trakpower 2s lipo so had to make some small modifications on the battery tray, such as adding double sided tape to the bottom of the tray without taking the other sticker off. This is to ensure that the thinnner lighter lipo battery stays on the battery tray along with using dremel on the top of the battery mount so I can pass the two positive and negative power cables through.

So finally got around to building my next rc car. This time around I was looking for a good RTR chassis that was 4wd and economically priced. The HPI Sprint 2 seems to have fit the bill for being under 200.00 for a complete RTR package. I did however replace the radio equipment and used my spektrum dx3r system, everything else is bone stock.
The car handles well with it’s stock x-pattern d compund tires, I would guestimate the top speed to be around 20-25mph with the 15t firebolt brushed motor. The steering seems a little loose and I would suspect that the chassis would probably not handle a faster motor than a 5700kv type without upgrading some key components.
I plan to do a video on performance of the stock setup followed by a brushless conversion and then another look at how the chassis handles more power.
Also note that since this is brushed, the power is not used efficiently so run-times are low.. around 5 minutes or so.
