engine

Hello All. I am new to 1/5 RC cars. I use to fly RC Planes and it was easy to determine the RPMs the engine is putting out. Just hold a tachometer up to prop and SHAZAM, RPMs. However, with cars, there is no easy way, or is there? I would like to tach the RPMs for my High speed, Low speed, and...

Hello, I am new to 1/5 scale. I have a question regarding the Redcat Racing RC Gas Engine Kill Switch. My question is how low does the voltage have to be before the kill switch activates? This question comes about as I was running my Dunerunner and noticed my steering was getting wider and...

I have a 30cc dune runner. And thinking I might get a bigger engine. Is their a block size or type to search. Or what is the biggest engine that will bolt in place. Thinking it might be better to get a bigger engine than to be trying to push a smaller to its limits.

dose anyone have any good info on getting more out of the stock 30cc engine. I tried to look around online for some tips to get more out of these engines but are quite vague. I used to be big on nitro but tired of all the tuning. but their was lots of little things you could do to get some...

Was ragging my Chimera around a field yesterday when I made the mistake of handing over the controls to my wife so I could get some actions shots with my iPhone. Anyway she decided to promptly roll it at 45mph with a hard turn. After that point I couldn't get it started again. I am assuming...

My XT has gotten to the point where after some run time, it starts to bog down and then dies. At which point it decides it doesn't want to start any longer. After letting it cool down some, it will fire up again an run for a short while longer. I am not getting thru a 1/3 of the tank before...

hi guys need some advice, im rebuilding my 30cc engine, it has 30mm crankshaft, i want to make it 27.2cc by a zenoah head 34mm and piston, what size of head gasket i will use? And what size squish clearance i must look? Thanks guys

Do you guys run dry at the end of the day or just empty the contents of the tank and let the fuel in the carb stay there? How'bout when preparing for winter? Also, if I want to work on the engine (change the carb for instance), how can I best empty it so I won't get gas everywhere when opening it?

Hi All, Firstly thanks in advance for any advice you could give on the matter. I have a Chimera which I have only had maybe 2 3 tanks of fuel on. Its been as good as gold started perfect every time. However I installed a JetPro pipe on it and now it wont start. They provided a crummy...

What engine is on MT V3 30cc? CY290 or GP290 or other?

Today my MT V3 crankshaft bearing failed, so need replacement. Going to replace all engine bearings. What brand you recommend? Also I need new head gasket. As I see on DDM, there is different width gasket, which one to get?

Good day friends, I received and engine from a friend that had a little issue, he said that while running the DR suddenly the engine idle shoot up and wont go idle. He switched off the engine to check for fuel quantity and had more than enough in it. He started the engine again and still...

Breaking my truck and things seem to be going pretty good but when it runs out of fuel it speeds and revs up really high. I'm sure it's an easy fix but I haven't been able to help the issue much. Sorry if this is the wrong place to post and if this is a really rudimentary question...newbie here...

I thought I had my XB all set up until I got past break-in (broke CY27 in according to DDM's suggested guidelines). Then, when I started running faster I noticed my brakes were pretty worthless at speed. I've been busy, but now I have some time over Christmas break to mess with it and would...

I have read and heard so many bad comments about the Dune Runner aka HSP Bajer. Recently I was at an rc track and started a conversation about the HSP Bajer or known to other market as the Redcat Dune Runner, so this one guy said that his friend had one and engine broke in less than 6months...

Halloo my new Redcat rally with a SCZ engine. :) morten

So I bought an MT non running as a project and then put it all together. Got it running but it ran like crap (hard to start, no power, won't increase in revs). So I put my finger over the spark plug hole and pulled and saw it had low compression. So I put a new piston and cylinder on it and then...

I'm looking at 29cc engines and have been thinking of getting one of the following: CY CY29RC $189 Zenoah G290RC $219 RCMK CR300F (4-bolt) $229 I've read about bad plating jobs on the CY cylinders on various forums, but most of those discussions are a few years old so I don't know if...
