Convert Hornet Front Suspensions

[TA-Mark]

I just hate the weird camber the CRP kit gives you with the drastic difference in upper and lower link length.

That's because the kit is not for a Tamiya. It's designed for the Futaba FX-10 buggy. Some of the parts can be adapted to use on a Tamiya Grasshopper/Hornet. Obviously the top links are one of the parts that don't work on the Tamiya, so you need to make up adjustable upper links with some threaded rod and ball cups.

I meant with a custom upper link, but during the suspension cycle. You can set it to have whatever camber you like at ride height with a custom upper link, but with it being so short compared to the length of the lower link, it gives bad camber during compression and droop. Granted it's just a grasshopper and not something like a short course truck, but still bugs me a bit.

Revise your geometry then, because mine doesn't do that. Mine stays at the same camber angle through the entire suspension travel on both the Grasshopper and the Lunchbox.

It does have the slightest bumpsteer due to the unequal length steering links, but then again, this is no where near as much as it was standard. I centred the servo on the Lunchbox and it has no bumpsteer at all. There's not enough room in the Grasshopper to centre the servo.

Hmm, I'll take a better look at it and see what I can do. I want to wrap up this project so I can move on to other things on the list.

Amazing Fox you have there btw!

My Super Hornet.

Has very little Bump steer ,No camber gain. Modern Shocks used !!

[kontemax]

Please, someone can tell me if this conversion is larger than original set up or equal? Is it like the Hornet/Grasshopper 1 or like Super Hornet/Grasshopper 2?

And in millimeters what's the front width?

Many thanks

UP!

Max .

My front end is 21cm in track. I don't have my standard Hornet here as it's my hobby house, I don't think it's any shorter in track.

Front shocks i used are Yeah Racing 70mm. Team CRP Futaba FX10 ( Same as the Tamiya Striker ) twin arm conversion. I used different front hub carriers to get a better roll center.

Hope this helps.

This is a good starting point. The original GH2 front width is 20 cm axle to axle without thread. With the tread is 21 cm. At the end larger than GH1 and Hornet.

Ski Patrol is almost ready to hit the slopes- (just in time for summer )

A little more tweaking and it'll be all set!

Sorry for the phone pics. I'll get better photos when its complete.

[MAD RACER]

What a great set up.

Very nicely done.

Love it!!!

This is $%&*£% unreal! Thats the spirit of RC, turning something so so up a couple notch. Look forward to your winter photos.

[Tamiya1/10]

opps double post.

[Flat_Out]

Thanks guys. I've got a couple details to wrap up on the chassis and body before it's all done. I'll start a thread for it this week and go into detail.

The front suspension parts are either from the CRP kit or aluminum pieces I drafted and then cut out on the hydrajet at work. I wanted to move the upper arm's inside pivot point to correct camber issues in the suspension cycle, and cantilever the shocks inboard to be able to mount the body lower without cutting holes for a shock tower. Though ol' Bessy ain't cuttin to great these days, so i drilled the holes in the parts by hand. Plus I wanted a snug press fit for the bearings in the rockers. We've got to get the machine tuned up and cutting properly/precisely...

Now that's original. Flat_out how did you mount the double wheels on the rear axle?

[Flat_Out]

how did you mount the double wheels on the rear axle?

It was actually a complete vintage kit (front ski's and dual rear wheel adapters) from "ST Accessories". They are a little different than the vintage Parma dual rear adapters. Honestly I like the Parma style better, and will hopefully pick up a set for this car soon.

I've got the packaging and part number for the complete winter set up pictured-

[mr crispy]

Thanks for that, didnt know a kit was available. Im quite tempted by the double rear set up... not too sure about the fronts though

Cheers

That "YETI" Hornet sure looks powerful!

Have you got any videos of it running?

Would be great to see it in action!

Yeah I agree.

I used the Team CRP FX10 conversion for my Super Hornet which is available still for little money.

I used DT02 front hub carries & axle blocks which gives a lot better front roll centre placement then the stock CRP items. Custom camber links were then made up along with DT02 steering links & servo saver were used in replace of the cheese straw links.

I used modern front shocks which required further modifications to the new CRP lower A arms. No bump steer and better damning which gives a lot better steering .

That mod really looks awesome! Where do you find the black part you're using on that Super Hornet?

[MAD RACER]

The black plastic part you talking about is it the shock tower you mean?

If so its the stock shock tower in the CRP FX10 conversion.

[Baja500]

The only performance shocks I know for the hornet period correct are parma or panda, or the crp hornet conversion kit or other 3rd party performance products back year's ago, which i own, best bet go the crp version.

I recently saw this one and I'm curios about it.

Is this some aftermarket piece or it's a custom aluminum part?

[BadWagon]

So much win in this thread... trying to keep my head from exploding....

[kontemax]

It seems handmade...
