This is unusual - have had lots of ASP/SC engines (they are the same motor made by the same factory) Big ends do wear but only after two or three years use. Its a very very good idea to use fuel with at least 18% oil in these engines and if possible some of that 18% should be castor. I find it odd that the engine was difficult to turn over - even if the big end was "picking up" it would not cause a lot of resistance. I wonder if there were bore problems and the big end has been overloaded trying to cope with a very stiff motor. Spares are available, if Hobby King don't have them try Just Engines. Lastly, you could just buy another ASP. Put a few tanks of fuel through it and there won't be a mismatch with the older one, seeing as its only had 30 flights.
I have done 2 rods on one of my engines. Well thrashed, on a pipe APC 9x10 using 16% nitro.usualy at 17-20Krpm, lasted about 2 years flying every weekend until I fried a piston and rod, fitted a new rod and piston lasted about 8 months before the rod started to fail again. Now just a show piece. Its twin is still being used, but in a normal config its about 3-4 years old.
thanks for the replies.
Yes, the conrod holes are clean and clear. In fact the engine is pretty clean inside all round. The engines were run through a few tanks of fuel before 1st flight. You need to be careful and thorough with twins.
Fuel used was a commercial brand, 5 - 10% nitro with coolpower oil. Last thing you need in a twin is a lean mixture. If anything they were a little too rich usually. Generally the operation and reliability of the .61 ASP was fine up until the last flight, when the motor became difficult to turn over, indicating something had gone wrong with it. The other .61 motor is still ok as far as I can see.
2/3rd to 3/4 throttle was fine flying the P-38 lightning, although a single .61 was sufficient to fly and get the model home if an engine failed.
oh yes. If you remove the rear cover and hold the crankshaft still, you can easily see a lot of slop and movement of the conrod on the crankshaft pin.
There should be none.
The rest of the engine appears to be fine.
I'd also like to add that My P-38 Lightning has not suffered a crash, therefore none of the engines have suffered damage from a crash.
The P-38 is alive and well still, but now grounded with one engine had www.link
bought 2 of these engine for a P-38 model. After about 30 flights, the conrod bearing in one of the motors has worn out. No replacement parts is available apparently. Not sure that I would recommend this engine to anyone at my club.
My faith in ASP engines is wearing very thin.I am now in the situation of having to contemplate buying yet another 2 engines for my model. I have serious doubts now that I will choose an ASP engine.
Hi Brett. I would check to see if the hole feeding the con rod bearing oil is free and clear. It could be that it has only been able to pick up oil from around the con rod and none has been able to penetrate into the bearing itself. Also i would check the second engine for signs or wear. If this also is having issues then perhaps the fuel is not suited to the engines or the mixture was too lean. Please do not think that i am doubting your experience but these are things that have to be looked at. You can pick up spares from places such as (e b a y) as the ASP shares components with the SC engine range. Its just a bush on the con rod so its an easy fix.
Also, What mixture of fuel are you using? The ASP is recommended for 10% nitro and then a shot of wd40 to be passed through the carb before being put away. The Nitro can allow moisture ingression and cause rust build up. What brand of fuel are you using?
Mate i agree on the right stuff, must be your mixture, the reason you are damaging your engine is because i wouldnt run anymore that 5% nitro on these engines, and always run no less that 18% oil with some of this percentage been castor, say at least 4%, i have had one of these now for 3yrs and still running strong, havnt done a thing to it. and gets a run at least every weekend. Dont use wd40 get some proper after run oil , wd40 is dry
Also buying pre mixed fuels from your hobby shop is not good, in my past 10 yrs experience, these pre mixed fuels tend to be lacking in oil, and make your engine run way to lean, if you serious about flying start to mix your own fuels, its not that hard, and at least you no whats in them. Please dont degrade the ASP brand, they are a very good brand, reliable when looked after, and great for value for money, have been using them for yrs, with no problems.
No I'm not denigrating the ASP brand. I've used them for about 20years, and still have a few that I use each week. My comments express surprise at the habits of the 2 x .52's etc that I purchased.
That said, my P-38 lightning is still using the same 2 x .61 ASP's, no further problems so far. Probably quite a few flights on them by now too.
Motor muito bom,recomendo a todos essa marca, j meu segundo motor ASP, o primeiro foi um 4 tempos, Muito forte, perfeito! Obrigado HobbyKing!!!
