Winter Project : R/C Air Car

Post  NEW222 on Sun Jan 14, 2018 5:04 pm

So, this winter I was wanting a new project. So, I stumbled across the RCM R/C Air Car. My dad had some scrap wood laying around that I took borrowed to make this. I wanted it as close to original as possible. I somehow even had a set of the 90 degree bellcranks! 72mHz radio, the only upgrade to modern is the use of a 7.4V lipo battery for power. As for engine, I had a tempermental MDS 40 laying around with throttling issues. But, as long as I can get it running and even have a little bit of throttle, I will be happy. I had a couple of very knowledgable people look at it and it was a poor throttling engine, and is why I pulled it from my airboat and replaced it. After buying it, I found the poor reviews on it, but when it ran, it did run very strong and well, just the throttling sucked! Anyways, I painted it with latex interior, 2 coats of polycrylic clear followed by a final coat of rattle can Minwax Polyurethane Oil Based clear. Without further ado.....

Plans are available online, but if anyone wants a copy, I am also willing to send them to you.

A nice project to entertain yourself! If you have a video it would be great!

About 30 years ago I made this car on air, I had material available, so I started working and I managed to stay for a long time.
He had steering on the two front wheels.
It was equipped with a potor OS .25 FP and servos futaba.

Wow MauricioB. That looks awesome. At least yours looked like an actual car, unlike mine. Unfortunately due to weather, I will not be running it anytime soon. But once I get it going, if I get it going, I will get some video of it if someone is around. Have a great day my friend.

Thumbs Up Thanks buddy, that auto - air was very fast, it made it work in cement and almost "flew", I miss a brake system, but if today I decided a new project, it would be similar to this one, just that I would place a cage for the bumps and protection of the propeller, in addition to a rear brake. If I think I was about 14 or 15 years old when I did it, you can say "I achieve the objectives" Thumbs Up

Thanks roddie for the compliments. I really would like to do that, but with the engine running the way it did last, I will require quite a bit of bench running before setting this thing free. If I had a better reliable engine, I would do it, but I do not have anything reliable at the moment. The only other rc engine I got at the moment is parked for the winter at the cottage on my airboat. But, next year should be different. As well, I do not have much time running nitro rc engines (except Cox) and am not sure of running and tuning in extreme temperatures.

Google search of MDS problems points to the carb. It’s possible a Perry replacement carb could fix the issue.
