Posted August 3, 201410 yr Hey all, I don't usually build much Technic, but this model slipped through the cracks. I wanted to make a simple RC car that was fun and easy to drive. This post is kind of one and a half MoCs... the Morgan is actually my second attempt at such; the first was a freelance car I called the .I used the RC motor because it was fast, and I had one. I used conventional RC equipment because I don't like the tradeoffs made on either of the PF controllers, and I wanted a bigger rechargeable battery. The GT1 drove well, but the unconventional suspension setup took up a ton of space, leaving the electronics hanging out and the trim hanging by just a couple studs... the exposed drive train also broke at least two old 16T gears. Thus, I built this car in response to those issues. The prototype is a 1935 Morgan Super Sports; I didn't try to model it exactly, rather, to save on parts and weight, I tried to outline it in the way that 80s and 90s Technic outlines vehicles, and I think it worked out pretty well. The hardest bit was probably suggesting that the body ends in a circle, which still doesn't quite come across. I'm using a 7.2v, 1600mAh NiMH battery hooked up to a cheapo "waterproof" ESC and an ancient Futaba two channel reciever. A chopped 9v cable is plugged onto the ESC to drive the RC motor. The three wheeled setup makes it easy to have indepedent suspension and enough space to not have the electronics floating around. It also eliminates the need for an exposed drivetrain. It's pretty entertaining to drive, mainly because you can drift on dirt or flip it if you aren't careful. That being said I'm happy that it's generally robust enough to survive flips without losing too many parts, but it's the fastest way to chew up your bricks.

August 3, 201410 yr Author WOW that thing moves, and I bet its super fun to drive, especially 3 wheels! Best part is it isn't even running at full power since the battery tops out at 7.5v, while 9v motor is rated for 9v o_o Thats awesome! You also used a custom battery? Yeah, it's a pretty typical RC car battery... about 1.5x the capacity of the PF rechargeable box, though NiMH means it's heavier as well. I would have liked to get one of those flat, 8-cell, 9v packs, but they didn't carry any at my local hobby shop. Edited August 3, 201410 yr by Commander Wolf
August 3, 201410 yr One of my favourite cars! That thing really goes, makes me feel like trying something similar myself.
August 4, 201410 yr Author Thanks for the comments, all. I think the the actual top speed is in the realm of 7mph, (about 100mph scaled), which is probably pretty accurate... not so sure about the acceleration, that's probably less so.
September 5, 201410 yr Morgan is one of my favorite brands and what you did here is splendid! I am impressed with it's speed, and you make it look very easy to maneuver. Really, really great!
