hey steve....since you're looking for a backplate.."rear crankcase cover" that means you have a starter box...just leave the pullstart on it and forget about it...if you're really set on a backplate call nitrohouse...some weather eh?...

GTX · #**102** 02-10-2003, 10:45 PM

I have put my H7 on hold for a while since I want to wait and see how the PBS version is. For the meantime, I am using a new Dom I ordered.

Marciano1969 - you are here too, huh? SWEET! Where are you located at? I go to Toys 4 Big Boys also. Cool shop, huh? I think the track should be bigger though. What setup are you running? I would race ya

baneonrt · #**103** 02-11-2003, 11:34 AM

Thanks for the advice coyote. I guess he just wants it to have a clean look and since the pull start is broken it's gotta go.

I assume you're in the Sacramento area from your comment on the weather?

Nevermind, just looked at your profile. We're expecting rain tomorrow, how much longer of good weather are you guys down there expected to have?

Steve

Just thought I would post a pic of my H7 pro. Just put it together over the weekend.

I was able to run my car out at the track fianaly, i did move to the 5000f, 7000c, and 1000r, and the car is handling alot better. The front end push is the thing of the past, I did put on the heavy black sway bar on the back. I think I am going to go with the 20 degre hubs in the front and try that out a want more cornering speed, then i might try the silver sway bar out front.

ezequiel · #**109** 02-12-2003, 12:17 PM

towerhobbies has the wing set, but do not have the
pullstart for the hyper 21. Where do you buy your
hyper 7 parts online?

windellmc · #**110** 02-12-2003, 04:15 PM

Marciano1969 - Make a new front swaybar out of 2.0 mm piano wire. Just use an existing swaybar as a pattern. Run the heaviest swaybar you have in the rear. I think it is the black. Run some blue Kyosho or Ofna springs if you haven't. That will also quicken up the handling compared to the black springs.

soslo · #**111** 02-12-2003, 05:02 PM

It'll get better Kolor Kraft.
What is bad too, is having a new track to run at, and they can't even have a grand opening race because of the weather. This will be the 2nd weekend they have tried, and it don't look good.

So don't feel like the Lone Stranger when it comes to not being able to race this time of year. Just think of all the broken parts you are not having to buy!! hehe!

ezequiel
Call www.nitrohouse.com
They have the backplate and whatever parts you need. They also have a 1-800 number at the top of their website.

Glad you got it criusn' Marciano!

Time to get it dirty now Dustin! LOL!!

Ofna as a new, PERMANENT, ezboard up now.
"0" posts in the Hyper 7 forum..
It needs to be filled it up dudes! (and dudetts if we have any?)

redcarrot55 · #**112** 02-13-2003, 12:42 AM

Does anyone know if the stock Hyper 8 port engine can use 30% nitro fuel? The engine mannual says I need to add shim to get the right timing for the 25% nitro and up, but Ofna tech support says no shim is needed.

Also, I'm breaking in my engine with the factory needle setting and 1/16" carb gap. It idles ok, but as soon as I throttle it up, it stops immediately. I tried to lean it out a bit thinking it could be too rich but didn't help much. I don't want to lean it too much during early break-in. Aany idea what I should do?

Thanks!

What's the spring tensions for the following spring set from the weakest to the strongest?

hyper 7stock purple
hyper 7 stock black
ofna blue (9.5)
ofna white (9.5)
ofna green (9.5)
ofna yellow
ofna red

I just bought the white set but feel like the tension is similar to the blue or black.

Thanks!

[B]It should be 40 in the front, and 35 in the rear redcarrot. The holes in my son's are drilled to 55 in front, and 54 in the rear. But I agree... That setup is a little on the soft side.

You guys talk about drilling the piston in the shock to 55-54
What size is that you are refering to??

Does Ofna make differnt size pistions ??

Thanks

I think they have only one size for Hyper 7 Pro.

soslo · #**116** 02-14-2003, 01:56 AM

Whites ar supossed to be stiffer than the blue or black, I thought. Haven't looked at the green, yellow, or reds yet.
Post the head shim question on the Ofna board, and put "Head shims for Hyper 8 port??... Rob, Angel, Paul ???" in the subject line.
That should get their attention. Chris gets confused sometimes, and does not always have a good explanation.
Found it is simpler to post things like that. You usually get a better answer.

Sounds like it may be too lean also. What temp. are you breaking it in at?

Just picked up a P5 for son's Hyper. (b/day time)
He kept wanting more bottom end out of the v01b, and I couldn't give him any more, even with the gold clutch springs.
Hopefully this will give him what he desires! LOL!!

Haven't seen any piston options for the shocks. Need to check on that.

Go away rain!!

windellmc · #**117** 02-14-2003, 12:00 PM

If you want stupid bottom end try a Novarossi SBK 01(short stroke 5 port) with drilled out clutch shoes, gold springs, and an 086 pipe with Waller power adaptor. Mine is set up that way and will spin all 4 on damp, sticky clay. Top end isn't as good though. There is supposed to be a 48 tooth spur gear coming out too. The standard is 46.

glacierdust38 · #**118** 02-14-2003, 12:32 PM

Okay... one question I have... what's the difference between the Hyper 7 Pro and the Ultra LX Pro that was featured in the March '03 editon of RC Car Action magazine (which I read all about and that this forum was about until I cheched the names and realized it wasn't the same).

OldskoolGT · #**119** 02-14-2003, 04:14 PM

redcarrot55,

It sounds kinda like your engine is loaded up with fuel. While the engine is idling, pinch the fuel line until the engine revs up from being lean and then stop pinching the fuel line. That will get rid of the excess fuel.

glacierdust38,

The Ultra LX is an older buggy made by Hong Hor, It's not competitive with the current crop of high performance buggies. The Hyper 7 is the latest and greatest buggy by HoBao.

soslo,

Let us know how the P5 compares to the VO1B. I am not sure if the P5 is gonna give your son more bottom end than a V01B, but the top end is gonna be way better for that 175' straghtaway.

I am really begining to like my P5 now. It actually has too much low end torque for my track. I was getting too much wheelspin with even the smallest throttle inputs. Maybe a less grippy clutch would help out. And the top end is pretty sweet now that I have leaned it out a bit. I out motored a WS7 powered buggy on the straightaway at my local track the other day.

soslo · #**120** 02-14-2003, 08:03 PM

He should like it OldskoolGT. But he ain't getting it until his b/day!
Also got a Mugen for his GT.
We were considering the Collari or Wasp, but don't know how dependable they are. They are stupid fast though! hehe!!
Found a set of the Ofna ratchet metric allen drivers. Those things are neat!
He shoud have a good b/day, and be set for the Nats. too. Even if he finishes in the F main. LOL!! The main thing is to have fun.

Now if this rain would go away, we may be able to break a new track in this weekend.
(wishful thinking)

Marciano1969 · #**122** 02-15-2003, 06:12 PM

I love this car i have got it to hook up pretty good, I am going to crimefighters at all four corners on the car, the car has been out at the track about 7 seven times since built. Never broke anything on it lost the set screw on the center cva but no biggie had a spare, the car is nice out there hooks up in the turn, level flight in the jumps.

Have fun racing everyone!!

fab · #**123** 02-16-2003, 11:36 AM

Finally went out and bought me this damn car (and spend all my money :-( ) It's the french version though, distributed by T2M and called Pirate RS2 pro. 90% the same I guess but came with -front- torsen, new hardened suspension arms and such, 4mm carbon at the front, and a couple of others things I don't remember.

Haven't driven it yet (work work work :-( ) but I should get it on track next weekend :-))

Oh btw:

:-))))

(more pics at http://users.pandora.be/fab/RC/ if you want, some are pretty big, be warned)

Can't wait to try it :-)

LouisB · #**124** 02-16-2003, 03:49 PM

Nice car Fab

I was down at the track today for practice and my H7 was flying. I had a good race with a Novarossi equipped H7 and a 7.5 K2 with a RB S7, my Hyper 8 port could keep up easily, and had as much if not more punch.

Go here to see a couple of very short AVIs of my car (and the K2) the track is very small but it levels the playing field between people with sport and competition engines. Maybe I should get a P5 for some real punch?

fab · #**125** 02-17-2003, 06:28 AM

Thanks

I think once you get at the level of these engines (S7, RZ, ...) it's more how you drive the car then how powerfull your engine is ...

Anyway I'm quite happy with the OS RZ on my hyper 7 (ran it in another car before), I just need a competition pipe :-/

Looks like a fun track, I wish I had a track like that closer to my home. This is the track i go to :

But I have to drive 1 hour to get there so it's only good for the weekends :-(
