RC car with chainsaw engine and custom build steering servo 

revamp it

Would love to see it man!!! That's awesome

Estou montando o meu

Well...? Did it work?

​@@matthewclark6239 Haha, unfortunately no. The Husqvarna had zero compression, and a piston kit to fix it cost as much as a used saw that ran.

@@K-Anator that’s sad

@@outdoorsadventures3722 Eh, figured there was a reason he left it behind. Not that I've been actively looking, but if I came across a used saw at the right time I'd definitely give it another go. Gonna need something soon actually, my brushless ESC caught on fire last week, so no more hucking the DT-02 around the neighbourhood, for a bit.

@@K-Anator you can get chainsaws at yard sales for really cheap I've gotten 4 at once for 20 bucks and only one did not run from a bad coil

So you have driving school?

Thanks! I would say it took me about six months to design and build the first iteration of the car. Back then the front suspension was different and it had different electric components. Plus there are many other updates made since then so I'm guessing the car will never be "finished". In my opinion this is the reasonable maximum size for an rc car because it becomes difficult to transport with a normal sized car. The only reason the steering is in front of the axle is that there was simply no room behind for the linkage. You are right that it could be easily damaged in an accident. Also the steering geometry would be better if it was behind the axle. I was eager to have a test drive with the new servo setup so this is the configuration I ended up with. At some point in the future I might modify the frame a little.

Dude that servo you built is fricking awesome man.

@@kravenkrawlhobby5438 Thanks!

Hi, and thanks! Here are the answers: 1) I have never measured the actual top speed but it may be calculated as follows: 2) The gear ratio is 9,63:1 3) According to Stihl the maximum power of the engine is 2,6 kW at 9500 rpm. The maximum torque is typically at lower rpm than maximum power, let's say it's at 6000 rpm. Because we don't have the exact power curve of the engine, we assume the power at 6000 rpm to be 2 kW (may be less than that). Now the max torque can be calculated and it is 3,18 Nm. Rear wheels are 11" in diameter and if we assume that the engine is running at 9500 rpm, the top speed of the car would be 52 km/h. In reality the engine should be running at even higher rpm (if it's tuned properly) and the speed should be around 60 km/h.

Thanks! Sure I will check it out!

Very true. To utilise the power band at all speeds it would need an automatic gearbox.

Thanks! It weights 41kgs / 90lbs.

@@willaa303 wow weighs a lot! Nice.
