Can somebody please help me. I recently purchased a Hyper 7 PBS and am having problems with the set up. All the power goes to the front wheels and hardly any to the back. I understand that i need to change the diff oils but haven't got a clue how to get to them. Is it an easy job or a mission? What weight oil or grease should i use? What do i need to dismantle?

Any advice would be gratefully received.

Many thanksa

On my Hyper 8 changing diff oil is not a big problem. Do you have a manual for yours? If not you should be able to down load it off the internet.

Then why did you recommend the 5625MG?

"All the power" what do you mean by that? the rear wheels don't spin at all or the front gets most of the power, may have some rear drag brake on. also dissasemble the center diff, may have chewed up a conical gear. also check the rear dogbone, still there, also the two rear axle dogbones, still there. last check the rear bevel gear and crown and set screw for dogbone carrier.

the 1313 is awesome on a truggy, on buggy it is more than enough, and they work underwater (don't recommend it though). my 1313 has lasted 3 cars so far and about 6 gallons or more, hyper 7, hyper 8.5 and now hyper st. i'm getting a 1015 just for some overkill on the st though, i love those ace servos. metal gears, heat sink, water proof, fast, strong, low power draw, what more could you ask for for under $100?

I have the DS 1015 for my steering and the DS 1313 for my throttle and brake on my Hyper 8.5, which is just about ready to fire up.

Here is the link for the Ofna manuals if you still need it????? http://www.ofna.com/manuals.html

Hobao or Ofna?

Can someone provide some background and explain to me who currently "Owns" the Hyper 8.5 Pro Buggy?

Also, I've been to the Ofna site and looked for a manual, however I do not see a direct link for the Hyper 8.5 Pro, can someone forward?

Thanks!

HoBao makes it, ofna distributes it in the states.

Ofna doe not manufacture anything they are just an importer for HoBao and Hong Nor. Ofna is slow in doing anything so the manual might not be on there site for a while or even years. Did you check on HoBao site?

What is it you are looking for???? I have both of them the 8 and the 8.5 pro manuals and there is not much difference. Let me know what you are looking for and maybe I can send you a copy of that page. Eric

The old Hyper 8 Pro manual came with mine with an 8.5 insert/ part list. The newer ones might come with a revised one that actually says 8.5 on the front. No big deal the differences are minor and I think it is a pretty good manual.

I havn't been able to drive my 8.5 lately. I have some Advantage spoked wheels coming in with ofna yellow molded foams. I will let you know how the wheels hold up as they will be bashed with badlands on them.

One thing I find about this buggy is that it is very easy to drive and it is easy to be precise and consistent with. I like it alot! I should be able to post up pictures of it later tonight.

Hey ProcessRacing, I got to test the advantage wheels 2 race days and they have been holding up great, using them with Losi XBT tires, although, if the travel of your rear end is too low, it will rub with the wheel, something that doesn't do with ofna or proline wheels.

Hobao

I meant ofna, not hobao lol, ofna do have wheels u know , I preffer hobao wheels though, they look cooler.

giddyuperic:

I'm not looking for anything specific in the manual, just more information. I'm going to be buying a buggy soon and the Hyper 8.5 Pro is one of the three I'm looking at.

Well I'll try from the main page. this post can be deleted.[&o]

I'm not sure what you mean, it rubs the uprights?

ProcessRacing: it will rub the big rod end that is connected to the upright.

haasjj: the stock foams are garbage, change them if you can. The diamond tires are very good but they wear out super fast, even on dirt.

The other ? i had was deleted because I moved it.
Yeah thats kinda what i thought. The tires look nice but I can tell there a soft compound they would be great on a high bite track but wear out quick. Oh well I'll mount them up and use them for racing when I get a chance, I have some other tires that are good for bashing and some for racing for my Turmoil that I can use for now.

what reciever battery pack and charger for it do you guys recommend to use with the hyper 8??

I use a Team Helotes 2600mah battery pack on my 8.5 but if you are using the 8 you would need the updated box.

or you could get this battery:

alright i just put a futaba high torq servo in had to use a smaller horn "cause orginal one wouldnt fit" and im not getting enough turning radius as i wanted how would i fix this?

If it is what I ran in to on my Hyper 8.5 the steering ball on the servo horn hits the servo so I just put a longer servo arm on it.

I had the same problem, the plastic horn was hitting the servo but I used an aluminum futaba servo horn that came with the Hyper ST PRO kit of my dad and it's perfect now!

haha wuppps i figured it out its my first spektrum and the servo was caped and like 70 i bumped it up to 100 works fine now
