New Engine in RC Ford GT

[jj1987]

To give a little background info on the car. It's an HP Racing 18ss. I bought the car used because it was a pretty good deal, upgraded gears, racing clutch, bigger pads, extra foam tires (for carpet tracks), extra street tires (for parking lot bashing) and no radio (so I could get a digital one). Anyways, the only down side was the engine was VERY weak when I got it, and it was pretty much impossible to tune it right. It eventually blew up, and about every part in the engine leaked, ruining any hope of replacing the piston/sleeve and getting compression. So that lead to what I wanted an excuse for anyways, a new engine.

Finally got around to finishing putting the new engine in the RC car. It's an O.S. .18 engine with rotary carb. If memory serves correctly, it's around 1.5hpm and the car is MAYBE 5lbs + AWD. I'll pretty much have to run foam tires (or so I hear) because the car doesn't hvae enough weight to get the rubber tires to stick. I need a $2 throttle linkage that's been on backorder for 2 months :thumbsdow and thats what's holding things up at the moment.

Anyone else on here have the remote control GT's?

Nice! :thumbsup
I have about 10 different RC cars, and have not found a GT body yet, although I haven't really looked.
Rotary carbs suck. Get a slide carb for more power! :biggrin
I have been playing / racing RC cars for 20 years. Most of my cars now are offroad, only because I have nowhere to race a street car. :frown
If you have traction problems, then the Rotary is fine. I am just a power hog. :wink
You should try to find your linkage online. I have found many things online that I could not get locally.

is it even possible to convert my car to side carb? If so I would be willing to try it. I need a .12 engine anyways to be race legal.

The place that is backordered is Tower Hobbies, and I've already ordered the part from them and paid. I might just buy it locally, a new RC shop just opened 2 days ago, maybe they have it.

I'm moving to Orlando (Computer Science program @UCF) in < 2 months, and I know a total of 0 peolpe there, so I'll have plenty of spare time to tweak things as needed. :lol

I'm not 100% sure what to do about my traction issue. If it's cheap enough, I might just get one of those garden sprayers and ask the local track about purchasing VHT. The only track I ran the car at was a smoothe pavement and wasn't prepped like a drag strip with VHT (is this normal? :frown ), so my car slid all over the track, the stopping distance and drivability was what you would expect from an RC boat, not something with good tires and pavement.

You should be able to change the carbs. Unless you are good, most wont recommend them because they can make you crazy. The power delivery of a slide carb is explosive and instantaneous.

This is a pretty cool car.

My heatsink touches the lexan body, what do you suggest to use in order to cut a perfictly round hole in the top (or rather make the current one bigger)?

 

[ROCMAN]

Hmm. I dont remember what I used to do.
You can try a hole saw since you already have a hole.

well I ended up being impatient and just used sandpaper with lots of time. Worked out well. Finally I got the thing to run tonite, this breakin crap kills me, I want to go full throttle! Even at 1/4 throttle this thing blows away any other RC car I've owned away, but I've only owned "toy" ones.
