    JK Cheetah 21 F1 chassis

    Had a few hours spare today so I finally put a motor into a JK 21 Cheetah chassis I have had for a while to try it out and run in a new motor at the same time.
    It's much better stock standard than the Cheetah 7 F1, doesn't have the same desire to leap out of the slot. Like the X25 the pans hang down below the chassis so needed .5mm/.002" tape underneath the bite bar.



    Once I had done a few hundred laps on choke running in and heat cycling the motor I tried all lanes on full power, and was within a small margin across each.



    Now that the Cheetah 7 F1 chassis isn't being made anymore, it's likely most clubs will allow these to be introduced. I'm hoping so with our racing here in NZ as this is much nicer to drive....

    Couple of gripes though...
    1. hard to get the bite bar out without bending it
    2. very narrow distance between rear axle uprights - why!? gonna take a stack of spacers to run max width...

    Don't build your hopes up too much for a change in F1 chassis.

    As long as there are plenty of the JK F1 chassis around, we will not allow them to be "grandfathered"

    So defensive Zip, is evil technology threatening your dominance? ;-) what's wrong with introducing new and better? Much like the 4002 vs Falcon 7 ....

    Au contraire.

    That is a stupid comeback, Steve.

    I expected better from you.

    Not my series, but how are you going to get new racers if they can't get the old chassis?

    There are still sufficient chassis available, either new on the peg or used in other racers' pit boxes.

    If only we were flooded with new racers - chance would be a good thing

    Better handling chassis, so less popping out of the slot, but weak little waist in the centre section bends more easily.
    No faster lap times, but less time out of the slot per race.
    Narrower distance between rear axle bushing uprights (duh why!!??)
    That's my assessment

    What an idiot.

    That post of mine was made 200 days ago today.

    Can you remember what coloured underpants you were wearing on the 9th of December 2015, or what you ate for lunch that day??

    Didn't you ask me on Thursday to grab the last chassis centre section for you?
