|Hi Carl, Im considering one of these - what caused the interference problem ? How did you solve it? I have several Zenoah engines for a number of years and they have never missed a beat, I wouldnt want to buy into any trouble.... but the price is tempting...|

Yep - I was trying to decide between the RCGF and CRRC engines. The CRRC ones look (too)colourful - and perhaps a little tacky/over blinged, but one guy at our club just bought one. I havnt seen it run yet though. Both seem quite cheap... My two ZG20 from Toni Clarke have run faultlessly for over two years now (one has a lot of hours on it now) and I suspect that I'll invest the extra cash in another CDi Zenoah. Still be interested in peoples comments of the cheaper options though...

Hi Neal I run a 45cc crrc (the earlier version ) in a 80 something inch Eurobat and it runs and pulls superbly . Flown about 3hrs and gets better every flight. The ignition system supplied interfered badly with the radio so I replaced it with a Westons runtronic unit . Its now excellent and starts easily. I dont know how long it will last as it has some serios rock in the crank bearings although the newer version has been completly re-designed .I have recently fitted and flown a DL 50 in my sons Vision . That started second flick and also runs superbly .No problems with the ignition unit supplied. Had to have a couple of tanks through it on the ground then the compression really built up and the general feel of the motor became much smoother. It is a very powerful engine . Parts are easily available and not to expensive ,through the uk distributors . Cost around £240 in the uk inc postage My other petrol units are a McKay 30cc , thats a great engine very powerful ,light and easy to set up .Its more expensive but is built specifically for the model market . My last petrol engine is a Zenoah 45 which I bought second hand .Beware of second hand units that have built up cranks if you dont know or trust their history or if there is any evidence of a sudden landing /crashes! It was fully cowled in a model and felt fine but when the cowl was removed some broken fins were evidence of a crash The Zenoah 's crank was twisted out of alignment and it had been assembled previously by someone who obvoisly didnt under stand how to use shims to adjust end play . Its been rebuilt now and seems to run ok ! ll . My son recently paid nearly £500 for a 3w 55i .It was heavy and cumbersome although the quality was superb , you still had to supply your own mounting and muffler . It was replaced with the DL50 ,much lighter and smaller , this was supplied complete with a muffler (although to be fair this does need some more baffles as it is quite noisy) and a mounting system .All for under half the price of the 3W, good value ? The Cheap engines seem OK but only time will tell .

Thanks for all that info Doc. I have just gotten my DA50 running again after it started running like a dog. Turned out to be a faulty ignition module, so I will press it back into service and put off buying any more until the cheaper options prove themselves a bit more. Though I don't see why they shouldn't last, after all the basic mechanical technology is pretty well understood and lasts forever in garden machinery (which is real cheap) for example - just so long as they havnt put all the money int fancy light crankcases and cut corners in the basic mechanics quality.

I have a RCGF 26 cc petrol engine in a 72” span Spitfire, and it performs very well.
The only “niggle” I have with it is that it won’t draw fuel from the tank when flicking the prop by hand, even with full choke on. It has to be primed with an electric starter.
But other than that it is a sweet and reliable engine.
However, if you’re looking for pure power, there are more powerful engines on the market.

|An update on the CRRC 45cc engine.Fitted in a 84 inch Eurobat . The outing before last I put the model into a steep climb ,the motor sounded very laboured for a couple of seconds then stopped ! Landed it safely and noticed some oil on the c/case. Later stripped engine down as it had no crankase compression and so couldn't draw any fuel. At first I thought the front oil seal had blown but late found it had sucked in the cylinder base gasket . The remains of the gasket were still in place but had turned all sticky , soft and horrible . I made a new gasket and fitted it and all is normal again . They may be cheap but they are powerful easy to start and keep on going.|

How annoying - they obviously dont use good quality gaskets - just the kind of corner cutting I worry about on the cheaper engines. On the subject of updates I noticed last weekend that one of my beloved ZG20's has developed a bit of endfloat that it never used to have. Runs perfectly mind you - and makes no abnormal noises. Should I worry about it or is it normal with a "high milage" engine... Doc?
