Yes, it's true....like you said......it just transfers the shock and energy through to the next more fragile part. I think on some larger race cars like 1/8 scale buggies and heavier short course trucks it might help to have alloy hub carriers sometimes. But when I see the aluminum A-arms.....I wouldn't go for that.

Mine does, I have a set of Top Cad +12MM(Volk TE37 knock offs) and a set of CML +6(Super Advan V2 knock offs)... now I only have 2 CML's that aren't trashed.

It's drifter bling...
I hate the term Bling... Lol. For me it was because they are beautiful rims and they are heavier which I like.

I have aluminum front and rear hubs, front and rear control arms, c blocks, mid brace... thingy, 2 sets of aluminum wheels, and a custom Monster can skid plate. A buddy of mine at the LHS gave me some 3mm aluminum plate so I am going to make a chassis for it. I am also in the process of making strut bars out of 1x1/8 plate. I want to find some aluminum bulk heads but I have searched to no avail and I do not have the dremel skills to make them...

Rear strut bar is done... functionally, visibly it needs a lot of work to not look like a chunk of aluminum with holes drilled in it and a few notches cut out... lol.

Soon, Soon. Just went to my first drift event at the Hobbytown races, was pretty fun but I have mixed feelings about the pavement.

HPI Sprint 2 Mods - Making a silk purse from a sow's ear.


Still in the UK...

Any chances of you tooling up to make these???

so basicly what i did was start by making a new post. the post now locates into the top plate to give it some proper support. the spacer in the middle of the second pic goes under the top bearing in the steering arm, by spacing the bearing up it makes the arm more rigid. the top tube then goes on top, this holds the steering arm in place instead of using an e-clip.

im going to make a new post for the right side that locates into the top plate. i was initially wanting to put bearings into the right side bellcrank, however after the mods ive done so far i dont think its needed.

If I can get my hands on Sharky's setup so I can measure and plot it I don't think it would be a hard design to replicate. The sprint one parts probably need to be stamped although if I could find a set I could definitely try... I am just not sure about the arms, I won't make/sell anything unless I am 100% confident and the tolerances are below .005". I am honestly disappointed in my rear strut bar because the outer mounting holes are .098 off... If I can ever steal my wifes phone from her ear I will take some pics of the unfinished beta rear strut bar.

No, they need to be machined.
OEM were injection molded... except for the aluminum posts.
Pity GPM, the one's that do the S2 parts in aluminum, doesn't make them.
Wish I had the $ for the machines - - - I've got the time, just no $
There's a company in British Columbia that I had hoped would pan out for some after market stuff = DUD
Owner wound up with eye trouble & last I heard they lost their part time machinist to a full time gig.
Hell, making better stuff just to replace the crap HPI sends out would probably be enough to keep food on the table and milk in the fridge.
Some people just ain't hungry enough to work these days I suppose...

Default ESC question

Will the stock ESC for the brushed motor sprint 2.....work with a 2 cell lipo battery without any modification or re-programming? I have never heard of a brushed ESC being programmable. I'm going to check on HPI website. I know they say sprint 2 brushed works with a 2 cell lipo. Perhaps there might be a micro size DIP switch on esc to change over to lipo? Maybe just ready to go with no changes?

NO -

You MUST reset the ESC for LiPo mode

+1 it is a series of beeps and flashes. Pretty easy to use once you get used to it.

HOBBICO BUYS HPI USA ASSETS

Pretty much explains the piss-poor customer service and the lack of customer service responses to emails...

OR

It could go the other way...
The new owners could (operative word) turn things around...

Yeah, right...

The re-released TC4's are startin' to look better...

I've been looking at these TC4 pre-built kits. With these you still need: motor, esc, servo, receiver, body, wheels, tires. Still seems a good deal at $149.

I hope HPI does well in the future. They offer more variety of cars and trucks than any other company. Maybe they tried to be TOO BIG. I hope the sprint 2 series also keeps going because it's a great RTR alternative to building kits....and can be endlessly upgraded.
