This is great work! Like the way you have tired to keep the 3D printed parts to a mint to save cost! We have a lot of Grasshopper and Hornets in my family and always looking for cheap ways to improve them.

Yeah it looks so need. Not sure what he's used to mount the bearing after cutting off the fixed axels of the Grasshopper gearbox. Do you think is possible to replicate this on the cheap?

So what's so good about the Thunder Shot arms over the DT03 arms? Also why as no one made a 3D printed part that lets you just put cheap DT03 arms on the side of the Grasshopper gearbox? Wouldnt that be easier? I found someone that's done this but with perspex and carbon fibre. See link https://free73.tistory.com/m/107

That's brilliant! IV not got a Frog in my collection. Mostly because of the bad things I'd read about the gearbox issue. But have always liked the way it looks. Maybe I'll get one now and try this out!

Am I right in thinking that this mod locks the Diff? I would have thought that would be a bad thing for a racing buggy?

Here are some more pictures that show the new Tamiya Black Star Dish wheels off,

Here is a comparison of the rear end before and after. First using Tamiya Frog rear rear axles and Wild One Wheels And now with the Tamiya Axles from the DF03RA or TA04 kit and Tamiya Black Star Dish wheels. I think not only does this look better but its also more practical. As grass can not get suck so easily in the gap between the rotating wheel hubs and stationary rear uprights.

I have to say it now drives amazingly! I have a Tamiya Wild One and race my Girlfriend Hornet in the park occasionally. I started upgrading this Hornet as I felt bad that the stock Hornet handling and tendency to flip over made racing the Wild One against the Hornet unfair. But now I think the Hornet with all its 3D printed parts has surpassed it in performance! I have recently also removed the Wild One Wheels and longer Frog rear axle and all the spacing. Using Tamiya Star Dish wheels seems to work a lot better. New Pictures soon hopefully! As more of the axle and rear suspension arms are protected inside the wheel hub. So now grass and leaves do not get stick around the rear axle so much now. Next I think I need to try it with the rear Anti Roll bar as iv not connected this yet. And now that the rear wheel base is not as wide I think it could benefit from this more now. Also now that the hornet has proper independent rear suspension that actually works. Its removed all bounce from the rear when grossing grass at high speed. Iv noticed that the front shocks are not so great and the front is now bouncing. I like the look of these aluminium vintage look setup. But since I recently setup the modem Tamiya Dt-03 Cva Damper Set on a Grasshopper 2/Rising Fighter Frankenstein car for that I build for my Niece. Iv come to appreciate their performance and the fact they don’t leak oil! I set the new Tamiya plastic Oil Dampers on the front and rear, on a Grasshopper 2 chassis with a Rising Fighter body, using the new rear soft springs that come with the new re-release version of the Grasshopper 2. Only other modification I made was the fishing wire mod to stop the transmission moving up under acceleration. And its handling so much better than Hornet with the same fishing wire mod and stock vintage aluminium oil shocks. On a Grasshopper 2 with Tamiya Dt-03 Cva Damper set the rear bounce is still there. But its no way near as bad as a Hornet. And it can definitely go round corners faster than a Hornet without rolling. But this might be more to do with the wider front wheel base of the Grasshopper 2 than the newer oil shocks at the front. So im thinning maybe getting the white version of the plastic dampers. Maybe leave them white or maybe dyeing them in a pot of purple!

I made some more improvements to the Hornet a while ago not, But only had the free time to share them. Got it to work with re-release Wild One wheels and hubs and and mixture of Frog and 39mm Drive Shaft Set for the DF03. To work with the new 3D printed rear suspension deigned buy PintoPower or AMPro as he also go's buy. Had to space it out quite a bit to work. Also found that wheel hubs that come as an unused parts on the Rising Fighter are comparable with Wild One Re-release wheel! Modified some Fog re-release shocks, To limit there travel and added ball links to them to stop them rubbing on the underside of the started Hornet body. Cut some frog/wild One axle covers up to fit Does make the rear end a little wider but it works! I have recent run it like this and found that it does get a lot of grass stuck in between the axle and wheels. So I may change this to use the Tamiya Dish Wheels and more of the rear axle protected inside the wheel dish this way. And this is how I got the battery to stop falling out! Its basically frictions fits in there now. So even if you take the battery door off and shake the car around with the car right ways up the battery will still stay in there! And here is the finished results!

Sorry long time no post. But I got it working, Just needed to drill out the hole a little bigger. Also got it to work with re-release Wild One wheels and hubs and and mixture of Frog and 39mm Drive Shaft Set for the DF03. Had to space it out quite a bit to work. Also found that wheel hubs that come as an unused parts on the Rising Fighter are comparable with Wild One Re-release wheel! Modified some Fog re-release shocks, To limit there travel and added ball links to them to stop them rubbing on the underside of the started Hornet body. one Cut some frog/wild One axle covers up to fit Does make the rear end a little wider but it works! Found some cheap back spot stickers on Ebay and stuck them to a Frog rear wing. As this started out as a regular re-release Hornet with some Jun Watanabe stickers also got cheep from ebay. But the rear wing broke back when it has standard Hornet suspension. So this way i can early replace the wing if it brakes again. Used RC10 wire wing mounts painted white. Also manged to get a Tamiya High Torque servo saver to fit buy cutting of the arm from the started Hornet servo saver and bolting it to it. Also used Traxxas Turnbuckle set for the Sledgehammer TRA1841 Also modified some cheap front 1/16 shocks off ebay. Cut the eye plastic mounting part at the top. And then just but a flat head bolt thought the top.

I brought a new transmission on eBay so that if it did not work out I could put the old one back. But I believe it's a Hornet re-release as it did not have the little tap that the grasshopper has. And was new and did not have any scratches on it.

Here is the side view. I went for black parts. Also I didn't glue the bearing cups in as they seemed tight enough fit in the 9mm hole.

So far so good! Only problem IV had so far is that after cutting the old fixed axel parts off. I also had to drill out the hole to 9mm to get the 3d printed bearing holders in. After cutting the old axel off the hole was only 7.5 mm big. So I used a 8mm drill bit first. Then a 8.5mm and finally a 9mm drill bit to make it fit. Also you can just about see I used 2x tamiya 3mm washers on the two mounting points on the right side. (When viewed from the back) As there was a bit of a gap on mine between the right of the gearbox and the 3d printed parts. But this might have just been the way I cut it.

Do you mean shims inside the shocks? They is an article on this site about a similar mod for the Wild One to stop the rear shocks from over extending?
