scrumpy jack Posted March 13, 2014 Author Share Posted March 13, 2014 Are pinion grub screws m4 size? I need to get some as the ones I have the hex slots are pretty rounded Quote Link to comment Share on other sites More sharing options...

tomr Posted March 16, 2014 Share Posted March 16, 2014 Looks great man ! Have the shocks made a big difference to the handling? Should have mine delivered on Tuesday :-) Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 16, 2014 Author Share Posted March 16, 2014 (edited) Handeling...er whats that?! I think I need to put in some softer springs as its pretty firm...but the shocks are much nicer than the stock ones. The truck worked pretty well at the bash saturday, apart from a loose grub drive shaft grub screw that stopped play. The thing is an absolute beast though! Im also going to try some different wheels and tyres next week to see if I can get it to handle slightly better..it seemed to handle better in nitro form, I think the brushless power is making it super twitchy..I may actually try to slow it down a bit!

scrumpy jack Posted March 18, 2014 Author Share Posted March 18, 2014 Excellent! I would suggest ordering some standard savage axles cups for the front..as the kyosho ones will break! I would highly recommend putting small bits of fuel tubeing in the front diff cups..so the axles are pushed tight into the knuckles...otherwise the first time you drive the thing and make a turn the axle will pop out the cup and smash it! Let me know how you get on with it...you will love it though, there a hoot to drive :-) Quote Link to comment Share on other sites More sharing options...
tomr Posted March 18, 2014 Share Posted March 18, 2014 Thanks bud I'll order some Sav axles soon as I can . I've took your advice and added some fuel tube to the diff cups Hope it's decent weather tomorrow evening :-) Quote Link to comment Share on other sites More sharing options...
yoodoo Posted March 24, 2014 Share Posted March 24, 2014 Excellent read that was..any vids on the both of them yet? Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 24, 2014 Author Share Posted March 24, 2014 Will have another up date this week, have splashed some cash on the madforce- got a new shell, which i've already sprayed...but Im not going to show you it until I get the new wheels I won off ebay theough the mail. Its going to look pretty darn saucy. Will hopefully get some decent video of it as well. 1 Quote Link to comment Share on other sites More sharing options...
tomr Posted March 25, 2014 Share Posted March 25, 2014 New body and wheels mmmm looking forward to seeing this . Still haven't run mine yet intact almost sold it but decided to keep it 1 Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 25, 2014 Author Share Posted March 25, 2014 Glad your keeping it. I saw it in the for sales and was very tempted to buy it of you! I got a new servo today and programming box for my esc..just waiting for the wheels now..should turn up tomorrow hopefully :-) Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 27, 2014 Author Share Posted March 27, 2014 (edited) New shell, also fitted an Altern steering servo, just waiting on new wheels...here's how were looking. Photo's don't really do the paint justice. Its Tamiya PS23 gunmetal. Edited March 27, 2014 by scrumpy jack Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 28, 2014 Author Share Posted March 28, 2014 So this morning while testing the truck I discovered the front shocks were hitting the inside of the tyres at full left or right lock...not good, the hyper shocks mounting points sit a little further away than the stock shocks, so I decided to offset them slightly and also at the same time toughen the lower shock mounting points (a well documented mad force weak area) so I grabbed some aluminium and my hacksaw and dremmel and made these up.. I then used lots of nuts and stainless bolts and mounted it all up like this: did the same on both sides: I'm rather pleased with the results...the shocks are now slightly further in-board and the mounting points should be far stronger Quote Link to comment Share on other sites More sharing options...
tomr Posted March 28, 2014 Share Posted March 28, 2014 Looks the biz Scrumpy I like the dark moody paint gives it a mean look and must say nice job on the shock mounts extra alloy always looks good in my book . Are the wheels the same size hex or can you fit different hex's on the madforce? Quote Link to comment Share on other sites More sharing options...

Are the wheels the same size hex or can you fit different hex's on the madforce? many thanks you can fit pretty much any size hex on the axles -14mm or 17mm the standard wheels are actually 19mm - some very strange thinking by Kyosho 'lets make a wheel that has a completely different size hex than every one else' !! the standard hex's you get are actually 14mm, but they have a little plastic adapter on them to make them 19mm to fit the wheels...most bizarre.

Nitroholic Posted March 28, 2014 Share Posted March 28, 2014 Loving the new shell Scrumpy These trucks need to stick with an 'old skool' look, and that one really works for me.I had the same issue with shock clearance on mine. The 40 series wheels I fitted do just rub a bit on the shocks. As the truck is light, though, you don;t want to go too firm on the springs...and the more upright you have the shocks, the firms ther shocks will seem. It's down to the angles the suspension forces act on. Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 28, 2014 Author Share Posted March 28, 2014 Indeed, I initially had the shocks mounted on the front tabs where the Axle arm joins the axle, which is a decent place strength wise, but the shocks were really upright and it sat the truck so high- I know the mad force isn't exactly sure footed, but the thing was undrivable. I so need to get some softer springs though, as the hyper ones are very firm. Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 29, 2014 Author Share Posted March 29, 2014 My wheels arrived this morning they were a bit of a nightmare to fit as I had some cheap buggy hex's and nuts and the machining on them was shocking....so spent an hour filling them and drilling out the pin holes slightly bigger to fit on the axles About half hour later I met the Colchester chaps at our bash spot..here's a few poor videos! oh yes and I broke it..again http://youtu.be/FHOJruVPhZA http://youtu.be/r0_v8c6aj2Q Quote Link to comment Share on other sites More sharing options...
tomr Posted March 29, 2014 Share Posted March 29, 2014 Looks like it goes well mate What did you brake ? Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 29, 2014 Author Share Posted March 29, 2014 not so much of a break, more of an annoyance- the screws that hold the ends of the axle tubes together pulled through the plastic, so the axle tube kept moving about, causing the dogbones to fall out and the steering to go very wonky! just needs some more screws in it and should be okay- the rest of the truck held up pretty well..my nice new shell is defiantly not so new looking now Quote Link to comment Share on other sites More sharing options...
jbar3260 Posted March 31, 2014 Share Posted March 31, 2014 love the new look scrumpy...gutted i missed saturday but went to a wedding on friday so was a bit behind on saturday lol for the vids though Quote Link to comment Share on other sites More sharing options...
scrumpy jack Posted March 31, 2014 Author Share Posted March 31, 2014 Yeah was a good morning..I actually managed to get through a battery and a half before the truck fell apart this time! Quote Link to comment Share on other sites More sharing options...
Taeonas Posted October 15, 2023 Share Posted October 15, 2023 Recently dug out my old and bashed Kyosho Mad Armour, and considering an electric conversion, stumbled over this forum. Now I'm waiting for the motor mount and diff. 🙂 Will have to go over this again once I have everything else. Two questions if anyone still follows this, to save a bit of time: What size pinion did you use in the end on the motor, and where is the best place to get one? Thank you.

Nitroholic Posted October 15, 2023 Share Posted October 15, 2023 (edited) I will have to check what pinion I have. I made my own centre chassis plate, used a Hyper 7 motor mount and centre diff, but mounted UNDER the chassis, with a bashplate to protect it. Gets rid of the chain drive and the awkward 3 speed setup. You don;t need it for brushless. It sits where the lower half of hte chain run is, and is tucked into the chassis in the same way. No ground clearance issues. I used a 1950Kv 4 pole motor. I didn;t gear it that high, and find it's a lot of fun on 4S. Run higher voltage and the handling is poor, as is reliability. I seem to recall fitting Hyper 7 diffs and pinion with straight cut gears. Was going to uses Savage ones, but they are fractionally longer and bind up as soon as you screw the cases fully together. Worked fine with the driveshafts I had. Not sure exaclty which ones I used. Might be a mix of Hyper7 and Kyosho. I also replaced the axles with HPI Savage ones, and fitted proper sized wheel hexes. The Kyosho ones are just poor for sizing. If you want....I can grab some pics of the setup I ended up with.

wolfie1 Posted October 15, 2023 Share Posted October 15, 2023 Interesting, i have 1 of these in the loft that has seen much better days, had never thought of brushless converting it! 2 Quote Link to comment Share on other sites More sharing options...
