the sway bars look different. looks like they put a little bend in them to help clear the drive shafts. very cool idea

Seems like OFNA stepped up a few notches in the quality sector since then though.
The RTR's that Ofna puts out are less than desirable, but there Kits and their 80%'s have been really great since day one, at least in terms of quality. On the track is another thing as to me, all their cars were just too heavy to drive the way I wanted them to. I hear the new Hyper series are seriously lightened so I think the days of 9 pound Ofna Buggies are over

Well quality can be two different things. It can mean mechanicaly good quality, which means it doesnt break down as often. Or it can mean quality feel, which is more like how well made something feels.
To me the Hyper 7 felt very cheap but yea sure it never broke down. The later cars and especially the Hyper 9 and Hyper star have been a big step up in that department I think.

Yes, they are angled now so they are almost flat going through the uprights.

Damned jobs interfering with our fun!

I'm looking to pick up a Hyper Star so thank you for this build thread!

I understand the design reason for moving the rear brake to the diff end but am curious how well it will stay clear of dirt/debris.

It wasn't a problem on the Hyper 9, in fact it works very well. My experience was that I would get far more muck on the front brake than the rear...

Well I disagree - I haven't replaced mine in about a year! The minute traces of oil that do come out over time are not a concern to me as a club racer. I'd be surprised if any brand diff was completely leak free, considering the work they do. But anyhow, as the old saying goes - works for me....!

Starting to look like a buggy now! Another change is the front chassis brace now lives up to its name, and attachs to the chassis rather than the radio tray.




Revised radio tray (old tray on the right). Its now fully enclosed, and a new top plate gives it some strength. Assembling the linkage gave me my first "Grrr" moment - trying to get the front brake linkage to thread into to the ball joint! Had to take to the ball joint with a small rounded file to open it up ever so slightly so the threaded rod could get in there and bite.


The assembled radio tray and linkages. Servos are coming out of my 9, but have to fix a slightly frayed wire on the throttle servo first (which would explain some of the radio glitching I've been having lately). The pivot plate the linkages attach to is much stronger than on the 9, with 2 screws, a locating pin, and an overhang that makes it fit snugly on the radio tray top plate. No need for alloy upgrades here any more.


I was hoping to get this finished in time for racing tomorrow, but running out of time and still plenty to do. Don't want to rush it, so I will have to wait for the WACC for its debut!
More to come....

I can't tell from the pic but is the front brake ball using a captured screw or is there a thread for a capture? I don't foresee it being a big issue but I can imagine after some wear that at full brake there might be a possibility of the front brake linkage popping off the ball joint. Also depends on the clearance at full brake if the servo horn butts up against the linkage adding to the chances of popping off.

I need to order me one of these buggies

That thought had crossed my mind too - its not a captured ball, and no thread as it has a hex head to screw it into the pivot. Josh Pain (team driver) has been thrashing his Star for quite a few months here and this hasn't been a problem for him to date. BTW - He took out the West Australian State Titles with this buggy, in March.
