Frankster 2003 Posted July 11, 2022 Hi, On summer vacation seeing family for first time in 4 years. I was planning to look for my boomerang which should e in storage for last 25 years. So far no luck. But my brother gave me his old Madcap. Here are some photos before I start dissecting and refurbishing her. anyone know if these controllers have any value on the second hand market? Quite dusty i think I can find better solution to the pins old school manual speed controller with 2nd servo seperate battery pack for receiver minimal road rash in chassis not sure why there was a piece of paper inside The elastic turned black and brittle light scratches outside body. Overall dirty and dusty with some mold Stayed tuned. This will be a long and slow build thread 4 Share this post Link to post Share on other sites
acprc 1442 Posted July 11, 2022 Airtronics XL2P is the same as the original Sanwa Machine A. If in good condition and complete with the battery holder there is a market but condition is everything. Share this post Link to post Share on other sites
naturbo2000 1257 Posted July 11, 2022 Really good condition tub! No cracks/splits in the usual places. Share this post Link to post Share on other sites

Frankster 2003 Posted October 22, 2022 Restarting this project. Basement find Madcap from my Brothers home. Wheels cleaned and Aerospace 303 added. Decals, bearings, servo, RSC and paint ready. This will not be box art Interesting to see old style of hex hub. 4 Share this post Link to post Share on other sites
Frankster 2003 Posted October 22, 2022 @Kol__ I am not familiar with the 1680 bearing. Is this hard to find? Looks quite large and needs to be to upgraded 1 Share this post Link to post Share on other sites
Kol__ 3377 Posted October 22, 2022 Hi mate, yeah I've only seen that larger bearing used either side of the Madcap/Astute/King Cab diffs, as you have found. Easy enough to get hold of, I bought 4 rubber shielded ones from this eBay seller and they are decent - https://www.ebay.co.uk/itm/382406023964?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=y95qAWuXR5e&sssrc=2349624&ssuid=tZpl78SaSly&var=&widget_ver=artemis&media=EMAIL Just let me know if you have any trouble sourcing some on your side of the world. From memory, the gearbox also needs two 1150s and two 850s mate. 1 Share this post Link to post Share on other sites

Luckily I can just drop the diff later once the bearings arrive and finish reassembling the car now. The other bearing sizes are easy to get, 1680 is a new one for me Share this post Link to post Share on other sites
Frankster 2003 Posted October 23, 2022 @Kol__ looked up the alternative bearing size 8x16x5 and found the bearings locally. Traxxas uses this size as well. 1680 is a Tamiya code. I see options for metal shielded and rubber shielded ball bearings? What is better? Share this post Link to post Share on other sites
Kol__ 3377 Posted October 23, 2022 Yeah the Tamiya bearing codes denote the external and internal diameters, so 1680 is 16mm outer diameter and an 8mm inner hole. Not sure about the width, so maybe best to check the width of the brass ones you took out to make sure they're 5mm wide? I usually go for rubber shielded mate, as they're supposed to be better at keeping the moisture out. Particularly useful for say wheel bearings, but not really necessary in a closed environment like the gearbox. That said though, the vintage Tamiya Super Bearings have a dark blue rubber shield. I took some out of an original Astute gearbox recently (same gearbox as Madcap) and all 3 sizes of bearings in there where of that rubber shielded type, and also as far a bearings go they are pretty sexy, lol🤔😂. They just look so cool with the text embossed on the rubber shield.😳, see... Share this post Link to post Share on other sites

Blue looks nice and rubber shielded is pricier. 10 qty non-shielded is cheaper than 2 qty rubber sealed 🤷♂️ Would the rubber ever disintegrate and end up being a problem long long term?

Frankster 2003 Posted October 23, 2022 Fast Eddy on Amazon is where I got the bearing size info from. Info looks legit 1 Share this post Link to post Share on other sites

Nah mate, seems to be more of a plastic type material than a rubber tbh, it's a fairly stiff disc that seals each side of the bearing. Can't see it breaking down. I think I paid a little under £4 for 4x 1680 bearings including delivery from that eBay seller btw👍 Share this post Link to post Share on other sites

Frankster 2003 Posted October 23, 2022 Cleaned up the Madcap chassis. Unfinished items includes new 1680 ball bearings, new CVA dampers to replace the stock friction dampers, install ESC, receiver, paint and decals. Will also be looking for an Avante cockpit and new front tires. 3 Share this post Link to post Share on other sites

That and the lower suspension arms are about the only original bits left Maybe I'll do a clear coat to lock the patina in. 1 Share this post Link to post Share on other sites

Frankster 2003 Posted October 25, 2022 Swapped 4 qty rear yellow dampers from TT-02B with my DT-03 Nissan Titan Redbull truck. Yellow goes well with the Redbull livery. The DT-03 black dampers will replace friction shocks on the Madcap. Interesting the damper lengths for both vehicles are different (front and back). Share this post Link to post Share on other sites
