Real or Fake? The performancelimitless 908 body

[Dan B.]

But hey, look at it this way. If you did crash on a 4000ft billiard table, you'd at least have rubber bumpers along the sides to soften the impact.

And I bet I’d still scratch! See what I did there?

this body 908 defintrelly exist I finishing my car - foto below

Left to finish
- antenna mount (dual antenna with diversity V shape
- 3d printed vertical 3cm stabiliser on end of wing
- distance spacer to move body out of back whell


I leave little longer body - and need design from scratch back wing - my choose

My back wing is adjustable - initial angle is about 5 degree and max is 16 degree (fixed by M3 screw)


Body will be tested on Limitless roller - this car already pass max 163 mph with old GT body.


Specially for test purporse i use last tested configuration with data log - 141 mph 8S XLX2 2028 800kv
only one changes will be NEW BODY to compare if really air drag is lower.

During ride I specially push car 5 scond longer on full to test battery - car need 10kW from battery to hold 225 km/h
(all data from ride on bottom of link)


work in progress

more detail to see on YT

I have in garage hobby CNC and I can design and create parts for my own use - this very help.


WORK IN PROGRESS

Nice work, can’t wait to see the difference in top speed!

 

[SP3SWJ]

In end of season 2022 i changed motor to 1100kv "need for speed" ;-) should go up to 300km, but attum and winter not allow for test. Now I specially back to slower 800kv specially for comparable results.

If I push full throttle and will be less ampers ;-) that will mean Cx parameter is better in 908 body. Max speed should be little hugheer too.

I'm excited too.

I really like your body mount system. Nicely done

 

[SP3SWJ]

In this car ALL is optimised for speedrun ;-)

serwo "gearing" change from 1:1 to 1:6

minimum turn back circl3 with EPA servo 120% give me about 3..4 meters circle ;-)

and I use own PerfectPass with some special features https://sites.google.com/view/smoothrottle-jerry-perfectpass

 

[SP3SWJ]

work in progress...
- wing stabiliser designed and printed
- side body distance ... and diffuser
- antenna pipe mount

tbc..

Any updates yet? The body mounting is great, as previously mentioned. Cool decals!

 

[SP3SWJ]

lack of time ;-( ... but in meantime SPRING changed to new 3x stronger. Ordered in local spring factory.

Photo show how to insert spacer made from 10mm pneumatic tube.

almost done... but stil something left todo

to all plastic parts need install spring thread for solid hold m3 screw

tbc


DECALC... hmm this is ordinary electeic tape ;-)

Glad to see it out there getting tested!

 

[SP3SWJ]

first conservative test done

less current draw than in old body

spring works super

I’ve got 15 of these bodies coming so I’m pretty excited to get them in my hands

Not sure how I’m going to paint them yet but I’m sure I’ll figure it out

 

[SP3SWJ]

Woow !!!!

In my opinion painting one color is optimum, syper complicated and beautiful painting mask shape of body.

I for example decide additionally have longer back and need design from scratch whole wing.

I'm very interested every new implementation ;-)

I'm currently discussing picking one up with you on facebook.
I bet Davide likes you right now!

I’m doing a bulk order of 15 to start with

Just want to see what the quality looks like before I go too far..I think they don’t come with any plastic on the outside which means I’ll be liquid masking the inside and outside to paint them
