Redback

That is so epic. Hope you make it to ROSSA Grogg and get your 100mph goal and hat 😄

Yes a bunch of youtubers run them, 140mph+ i think it the record for a wltoys, rossa wr holder is a @pieman5 175mph with his pancar.

The Hyper 7 hit one of the tires protecting the traps at ROSSA last weekend, big fail on my part, couldnt abort in time due to an unknown steering issue. Had just done its first 101mph pass 30 min before. Checked over the actual damage, looks really sad and bad, but in reality... Oone broken bell crank, shattered lower pin and front diff input housing tower mounts. Chassis is still straight... Motor mount is fine, all drive shafts straight, no screws pulled through, pretty speachless... They make these old hypers tough as nails.

17t & low kv as possible motor to stop stalling / cogging

Mines 99% stock. the only change is the rear drive shaft is custom made, the rest is all the stock plastics, nothing fancy. (red and green shell) The lads (yellow and orange) is mostly ftx carbon parts and upgrades, and honestly they made the car worse, it was uncontrollable at full speed, when my stock banzia was planted no issues. I dont use parts from other rcs, the challenge is to the get the stock cars as fast as possible, this means plastic hexes, unlocked diffs, etc. Obvoiusly i have removed the garbage motors and escs and put in semi decent race ones.

Thanks chaps, was up late upgrading the cutting board splitter with something decent. Ready to be sent...

I was all out of the high speed ginger nuts...

The fastest biscuit.

lol yeah, its only because its got a bangood esc (60amp) and motor (4300kv "540" more like 3652) in it... i recon it would be fine with a higher amp esc and sensored Can keep it in slow motion it wont stall out, i expect ill put a better setup in on the day 😅 its fine but i rather not smoke its nice to have for a basher or backup edf esc

Great start, a record is a record, the slower the first record the faster your next pb will be 🙂 Talking of speed runs. Geared the DR10 to the moon, using the hpi rs4 stock spur and highspeed pinion 😄 poor thing wont launch by itself its geared so high, saftey feature. It wont run away from you, just melt on the start line 😂

Theres always room on the ceiling, i know a guy that had 8 planes stuck to his ceiling, kept them out the way and looked awesome.

Yeah cutting the chassis is always a last resort as its not a reversable modification and the chassis on these contain the spur gear housing that means any cutting is a new chassis. Also i use the same gears for the other cars so a cut down one is good for them too. The hpi and wheels is a pain in the butt, the rears have a nub when cut off makes fitment better but still have to move the shocks way in etc. The fronts are worse with the long steering arms and top arm pivot not giving clearance. Found that contact drag foams fit front and back, backs wont clear the fronts and are quite a bit wider. Could run 2 sets of front drag foams, these are the only ones that fit as 26 - 30mm x 60mm foams will not fit the fronts. These also vastly improve the handeling and stop it being super twitchy on steering input. Even with dual rate all the way down with 26mm fronts it was all over the place. Now the body fitment is another thing, either i cut out lots of body or trim the wheel. Will probably get some fronts for the back and keep the back ones as backups. Did you book into rossa? Yes not seen stews gearing video but i also find running negative gearing eg 32t pinion 27t spur good as you can not get small spur gears like you can get pinions. Also not sure with the tamiya but for the ftx you need to make a custom drive shaft to accept pinions, for the hpi is a bit easier aslong as you have the right bearings to make up for the lost space.

So many spares i could open a shop.

Poor mans lathe, a dremel.

Cut a pinion in half.

No i wont chop the chassis, ill chop the pinion to clear the chassis 🙂 Poor mans lathe, run the motor and the dremel to get a balanced cut.

Thanks mate, its less about weight more about stopping the air getting up under the bumper foam and making the body parachute, they are pretty light maybe not stiff enough

Not to start with, was going to try the high speed gearing, skipping that, have to grind down a pinion to fit or chop the chassis somewhat, going to try grinding a pinion.

Not happy, spur gear melted doing a range check, was going 5mph at most. Really cheesed off, been nothing but a problem child, one run broke chub, 2nd run melted gear. 😞 Feeling a bit of regret getting this, had high hopes but so far nothing but dissapointment. Painted the body tho turned out ok for spare empty cans.

Splitters made and fitted, old cutting board does the job.

Parts arrived, still cant run 30mm foams on front as turnbuckles are to big, cut off the nub stopping the backs being fitted, have to run 26mm on front then as not enough axle stub for hub extender. Diffuser added and cut back to allow the foams to expand, recentered servo, need to shorten and update motorwire to 6mm bullets, body cut and paint to do.

Few parts inc, wider wheels, rear diffuser, will finish build this weekend 2 weeks till rossa first pass, no road shakedowns cant risk it. Have to also put on the other 0 caster c hub as running a '6 and the spares arnt spares and are 0 caster pulls either side even double trimmed. Want some spares for the event but mostly out of stock, fingers xd no crash maybe 150mph is a dream, now i see the chassis it seems long way off.

Getting Rossa ready. The old "typhoon" will be sent again after considering passing it on, we got a new friend, "hurricane" another banzai. Reused the body from the hyper10 that wont be sent, retrofitted and chopped back. Typhoon is also ready to rock, back to the old gearing 4s setup, no 3d printed parts, just need to fabricate a front splitter with some chopping board.
