    Green fluid from pull start?

    in General - Nitro

    Posted

    It isn't the flywheel that's getting stuck its the piston and sleeve and I'm guessing that your engine is still new if so the tolerances inside are still going to be very tight, even more so when it is cold.  Its always a good idea to pre-heat a nitro engine before trying to start it as this will expand all the metal surfaces and make starting much easier.

    I wouldn't right that engine off yet. The reason that it is stiff right at the top of its stroke is due to whats called 'pinch'. The sleeve has a slight taper towards the top which 'pinches' the piston at TDC to create a seal and compression in the combustion chamber. Without 'pinch' the engine would run like a bag of spanners if at all. So if yours is tight at the top that is fine, that is how it is supposed to be.

    See I was wondering if the piston was right at the top of its stroke when it was turned off. If it was, as the engine cooled the piston and liner would have become stuck together effectively locking the engine up. I'm sure I had this situation happen on an old TS4N and that's what the problem was.

    YOUR top five favorite RC cars.

    1. Tamiya Monster Beetle - for pure nostalgia. First proper RC i ever owned.

    2. Hyper 7 - fast, tough, cheap and bags of fun. Ive built two brushless ones and they both fantastic.

    3. KM Baja - brutal power and very loud. Has cost me loads but it has been worth it.

    4. Brushless Lunchbox - fun basher and fast enough to keep you on your toes.

    5. MTA4 S50 - big loud and very fast, killed by lack of parts availability. Real shame.

     

    I just want to throw in my least favorite RC which was a HSP nitro buggy. It was the biggest pile of junk I ever owned. I wasnt

    expecting miracles but this thing broke literally every single time i tried to run it. Actually no, I did manage to get one full tank out of it without

    anything breaking but every other time it was game over. Sold for parts in the end.

    Im running a Quicrun 150 esc, HPI Alphastar motor and a 17t pinion. It is fantastic fun on 3s and insanely quick on 4s. Id like to try more but there is a 4s limit on the motor. Id definitely recommend servicing and refilling the diffs, it made a night-and-day difference to mine.

    Tamco TAC330 2.4ghz TX - Spares or repairs

    in For RC Sales

    Posted

    Tamco TAC330 2.4ghz tx for spares or repairs ONLY. Aerial is damaged and has a logic board fault where you would move the sticks and the car would respond about

    3-4 seconds later and the range dropped to about 10 feet before signal was lost (fault wasnt caused by the broken aerial). The sticks, switches and screen are all working fine though

    so could be used for spares in another tx. £12 inc post. buyers pays fees.

    These are the only two Tamiyas I have left now. The one on the left is my idea of what a child of a Sand Scorcher and a Monster Beetle would look like, while the one on the right is a very very original 1986 vintage Monster Beetle that used to belong to a dear friend of mine. I have even got the little 'pay-weekly' book from the model shop it came from. Lives on my nice warm shelf now with an occasional run in the sunshine :)

    Hyper 7 nitro odds and sods

    in For RC Sales

    Posted

    Job lot of Hyper 7 nitro parts left over from my brushless conversion. The engine did run previously but has been taken apart and appears to have some bits missing so it is being sold

    as spares or repair only as i cant guarantee it. It turns over ok and the pullstart is fairly new as far as I remember. So what you see is what you get basically however there are some small bits that aren't pictured that I will throw in too. £30 inc postage for the lot.
