Hi

My banzai has been under extensive work, been trying to perfect her as an all rounder.

Finally got her going for speed runs and got 71mph at half throttle!!

Running a max 6 esc and 3674 2200kv surpass motor.

Gotta go faster 😁

A complete custom rear diff drive output using an old ftx highrock axle. Based on @RC-Complex's design however allows using the stock Banzai middle drive shaft.

The alternative choice is like RCC has done and replace the whole center drive train and beef it up to take 6s power.
As im still only running 4s hopefully this experiment will work, or it will explode either way good fun 😄

Stripping the car back to fit the new driveshaft, good time to service and evaluate what high speed and power does to a car not designed for it.
Plenty of chipped teeth doesnt affect the gear meshing, good for some more runs.

Plastic spur looks good for more runs, as does the diff pinion.

Had to move and redesign the driveshaft support.

Lots of other changes, just gotta wrap up bench testing, before taking it out for a real test, space is getting pretty tight.

Great stuff @Redback . 
Progressing nicely and hopefully the extended range as well as the other mods will see you get to the next cap. 😏 

The tyres as someone else from ROSSA already told you will do much better when on the ground. If I revved my Typhon up to full rpm off the floor I'd blow my GRP's off the rims for sure, ...different when they're under load on the ground. Look forward to catching up in August and hopefully seeing some new PB's for everyone. :good:

First run of the year with the new gearing, motor, esc and 3d printed parts. A easy going shake down on 3s, did max it felt a bit weak on the power side, more road / time needed.
Main test was the gearing and it didnt explode so thats a good start.

ROSSA attempt 3 for the Banzai!


Was hoping for 125mp and got 0mph as it drove off by itself as i set the failsafe to 50% breaking.... but on the banzai its reverse rotation on the motor for some reason, thus 50% throttle right into the grass bank. RIP
Bent drive shaft, smashed shock tower, 3d printed parts vaporized, smoke poring out of something, new tires shot to bits.
Really gutted it didnt get to run, with so much effort put into prep, but thats how it works live and learn. Use the memory function in the remote to ensure your failsafe is failsafe for the car your running and not a safe FAIL....
Decided i wont run it again... i'll put the 108mph gearing back in  and its now handed down to little redback to send it and get his first hat as he did outstanding at the event.

I "liked" your post @Redback because although it didn't go well for you with the Banzai it'll be great seeing the little man having fun with it & hopefully getting his own cap. 
Best of luck to him.

Cheers chaps, it had a good run and its in safe hands, had a mess about with it before the crash and it wasn't working 100% over geared but still did some 60mph passes on 3s, awaiting the results.
Going to fix the issues, maybe pick up some carbon-fiber sheet to replace the 3d printed parts. Also no footage from the event as my phone has died...
There has to be some changes kept as the sensored system that was used prior, is going in the savage xs if i can find the right gearing for it.

She will run again perhaps in aug...

ROSSA attempt 3 results. Couple of test passes got about 60mph on 3s. Didnt manage to test 6s or 4s as crashed it on the waiting line lol.

Not sure how the shock tower got taken out, Shock bent the front driveshaft too. Going to upgrade the tower to carbon fiber.

Side skirts shattered, proto types none the less, thinking carbon fiber next time do it properly.

Front splitter vaporised, needs carbon fiber i think next time.
Overall very light damage and cheap to repair got off lucky really.
