I need to purchase an engine
in the above range .... Any Recommendations???
Zenoah??
BME???
DA??
3W???

What are the cheers as well as jeers ???

Buy a DA I have two they are powerful and have a very linear throttle response.

DA 50
ZDZ 50
BME 55 (lightest) i believe

HOW ABOUT A FOX 3.2? IT WEIGHS 56 OZ. HAS A C&H AUTO ADVANCE ELECTRONIC IGNITION. SWINGS A 22" PROPELLER. HAS A SINGLE BOLT HUB, AND AT AROUND $550.00 ITS WORTH LOOKING INTO.

Stuka Barry

I am searching for an engine for my
Ju-87 B Stuka from Ziroli plans???
This would be my first gas engine in this
range, and I don't like troublesome ones!

The four engines you mentioned in your post are all good and troublesome engines.

The BME will be the lightest, Zenoah will, be the heaviest.
Zenoah has a magneto ignition so you do not need a separate ignition module and battery.

The others all come with the module, you supply the battery, these are easier to hand start also...

THE BEST, MOST TROUBLE FREE, AND CHEAPEST ENGINE, WILL BE THE ZENOAH G-62.I SAY THE BEST CHOICE BECAUSE, ALL OF NICK'S HEAVY METAL WARBIRDS ARE DESIGNED AROUND THE G-62.THEY WERE THE MOST POPULAR ENGINE AT THAT TIME.THEY WERE $275.00 AT THAT TIME TOO.LIKE JEMO SAID, THERE IS NO BATTERY OR IGNITION TO FOOL WITH. JUST A KILL SWITCH, AND THATS ALREADY WIRED UP IN THE MAGNETO. THE G-62 IS ALSO THE HEAVIEST SO CHANCES ARE, THAT NO DEAD WEIGHT WILL BE NEEDED. THE CHOICE IS UP TO THE MODELER AND HOW MUCH HE WANTS TO SPEND.

I am sure I will ruffle some feathers here, but i would stay far away from magneto engines if your budget will allow. Some people will say the magneto engines are the most trouble free, but my experience is anything but that.

Remember that a magneto engine is difficult to hand start at best. Most require either a really hard whack on the prop, a big spring on the engine, or a big electric starter. Because of the fixed timing of these engines they tend to kick back making them the least safe of the gas engines. Once they are running they run well at WOT, but because their timing is usually set in one position, runs rough at idle. Today, most magneto engines are considered "low performance" engines. If you have to get a G-62 have RCIGN convert it to a electronic ignition. You will have a better smoother idle and easy hand starts.

I am a proud BME fan, but I wanted to throw another name in the mix that is at the VERY LEAST comparable to all the others mentioned........TAURUS----the Taurus TS52 is a 52 cc engine that isn't the lightest in it's class, but is definitely the SMOOTHEST. Actual weight is similar to the other 50cc engines. I ran a SIDE-BY-SIDE comparison with this engine to my BME50 and they were both on the money with the same props.....tried about 6 different props including a 19x10 3 blade. Both engines were BRAND NEW.

I have a 3w50i with a 24 10...runs great!

Does the location of the carberator
affect the performance ???
Do I have to do special openings in the
cowling etc.... for best results.....
Guess side monuted are the best choice!

THE G-62 CARB DOES STICK OUT BUT I PAINTED IT O.D. TO MATCH THE COWL. NOT AS NOTICABLE. WHILE ITS TRUE THE G-62 DOES VIBRATE, A PROPERLY BALANCED PROP WILL HELP. THE G-62 HAS THE SMALLEST FLY WHEEL OF ALL ZENOAHS, HNSE MORE VIBRATION AND HARDER TO START. YOU DO HAVE TO "SMACK" A 62, BUT A PROPERLY PRIMED (WELL FLOODED) 62 CAN AND WILL START ON THE THIRD OR FOURTH FLIP. AS FAR AS AN ELECTRONIC IGNITION GOES, YOUR ADDING A SWITCH, AND A BATTERY. FOR THE PRICE OF ALL THAT MODIFICATION, YOU MIGHT AS WELL GET THE FOX 3.2 THE G-62 IS A FINE ENGINE AND WILL GIVE YOU YEARS OF RELIABILITY AND WILL BE ALL YOU NEED FOR THE "Z" STUKA. AS FAR AS A TAURUS FOR THE STUKA OR ANY "Z" WARBIRD, IF THEY ARE LIGHT THEN YOUR GOING TO HAVE TO ADD LOTS OF DEAD NOSE WEIGHT,SO WHATS THE SENSE? THE STUKA AND ANY OTHER INLINE WARBIRD ARE'NT THAT BAD FOR ADDING DEAD WEIGHT., BUT ANY OF THE RADIAL SHORT NOSED WARBIRDS, I'VE SEEN AS MUCH AS SIX POUNDS OF NOSE WEIGHT FOR BALANCE. EXAMPLE: MY STUKA WITH A 101" W/S WITH ALL FUNCTIONAL CONTROLS AND THE SIREN WEIGHS 28LBS. G-62 NO DEAD WEIGHT. THE "Z" HELLCAT 96" W/S WITH RETRACTS COMES IN FROM 38 TO 45LBS. BOTH AIRCRAFT ARE 1/5TH SCALE. THE "Z" CORSAIR COMES IN AT 31LBS WITH A G-62 AND DEAD NOSE WEIGHT.

need opinions about the Fuji 64cc BT-64A
engine??
Read an excellent review in R/C Report magazine??

Hisham, your going to get as many options as there are engines available in that size range.. there are few "Dogs"... in the entire bunch.. what you won't be able to find out is which one is "THE BEST".... cause there isnt one specific engine thats better that all the rest for all applications. Having said that..Take all the requirements you have for YOUR plane.. and weigh them against whats out there.. I worked in the Small engine industry for 10 years and its not rocket science!!.. Get something that workes well... fits your space. and you can afford.. chances are.. that it will be relatively trouble free. Unless you are planning to do 3 D type aerobatics, where every little ounce is sometimes a consideration.. I dont think you can go wrong with just about any engine. I have both types.. mag and ignition.. they both work fine.. the ignition engine is a little smoother.. and easier to start.. but. my G-45 works well too... Regards BobH.
