Progress is coming along now on the Golden Arrow. I started out with three of them and planned to make two but discovered that I have only one usable chassis. I made a custom rear suspension shaft out of an m5x140mm long (5mm diameter) hex screw. The same will be done for the front suspension shaft as well. I also used m3 (3mm) hex screws and nylon insert locknuts to secure the round metal plates that attach to the differential spur gear so now the Golden Arrow can be disassembled much easier for servicing. I decided to utilize my trinity epic 27 turn stock motor (brushed, ball bearing) as the motor case is black and matches the Golden Arrow quite nicely. The gearbox is now rebuilt with all ball bearings and new axle shafts (traxxas #1246) were also installed. I will be using an hpi sc-15 esc. And, a hitec mighty mini servo for the steering. Titanium turnbuckles are planned. As always, progress has been somewhat slow but now it is finally starting to come along. I welcome questions, comments, and any suggestions. Thanks for watching.
Effort to completely penetrate a 1/4″ thick piece of welding steel with the 62 gr NATO “green tip” round in 5.56 mm. This is NOT armor plating….far from it. Distance to target was 80 yards. Footage includes slow-motion of the hit.
I would like to try this again at a longer distance, such as 150 or 200 yards.
