Looks great Karl & Don. That new windscreen looks swanky, is it cracked?

3 months to go, yikes!

I'm not, but I guess it's just the rippling of a protective film. Shape looks better to my novice eye.



Here's greenie as of this weekend, hopefully start wiring the Motec soon.

Dean,
I REALLY like seeing bars ahead of the fork tubes on greenie, puts yr arms in a much better position.  When are you gonna run it?  where?

On Lexan cracking, i'm no expert but i gotta tell you it is a world better to play with than plexiglass.  It seems to have mechanical properties more like a soft metal than plastic.  It can be bent like crazy and drilled like aluminum,  although it apparently takes heat to bend it permanently. It doesn't seem to easily crack. (i'll probably eat those words).  As you note, the "cracks" are the protective film.

Thanks, more comfy than chicken-wing posture too. The plan is Speed Week, but I've got a lot to do. That's your plan with Don, right? Shakedown meet with modest engine?

Excellent, see you at Speedweek if all is settled down at Casa Sabatinelli.

Yup, you have our Plan exactly right. 
1. see if it goes straight
2. learn to consistently pull the HS parachute and not the engine bay fire bottle

If you've told us about your new bike project I missed it.  So - how 'bout telling us about your new bike project?  Thanks.

Great up date. I enjoyed this build the first time. It will be great to see the lakester run in its new configuration.

Thanks for the tweak diary

Sorry to divert the thread, I PMd Jon and Ransom about the bike.

Karl / Don, are the wheels, chassis lengthening and windscreen the major changes? Anything else planned before its debut? Will it be painted green? :)

just a postscipt here. 
Some may notice that no hp issues are addressed.

we have a 2014 plan as follows:
2014 Objectives:    
   1. Build/modify a good looking Lakester with no compromises on safety, handling, reliability, driver ergonomics, data monitoring.
   2. Don & Karl get solid experience in each personally driving a 200mph parachute car at Bonneville.
   3. TFA Racing Team develop & implement robust operational procedures & checklists
   4. Develop accurate predictions of #5448's "mph vs hp" potential      (chassis dyno + actual Bonneville speeds + wind tunnel)
   5. D&K make informed decision for 2015 season:
        - make our TFA Racing Lakester faster, or
        - make our TFA Racing Lakester slower, go for record
        - make "minor" improvements and run it for "cheap" fun
        - sell the car and take up fishing

Sounds like a great plan and a more realistic one than I often read  :-),
