Besides not being able to see the engine, you have to take the cowl off to work on the motor. I really like to keep a check on my motor as it can be important. Once I crashed a Giles with a OS46 because the muffler came loose in the air. If I hadn't had the cowl on I might have seen the loose muffler. If you do decide to run a cowl, make sure very thing is set up properly.

I have argued for years that streamlining R/C airplanes is a waste of time and can be detrimental. We fly close-in and are constantly turning to keep the model in sight. Other than racing, or other special applications, a draggy model is much more fun to fly as an R/C model than a really slippery rascal that goes too fast for the short distances in which we operate.

I too like my engines hanging out in the open. Besides, if it weren't for engines, I probably wouldn't be in R/C anyway.

Now to get my G2300 broken-in on the bench so I can switch it over to Diesel...

Status: offline 		After checking the temp of these engines by hand (don't have a temp gun) I have come to realize that they don't get very warn on the bottom of the engine. In fact if the bearing area is hot something might be wrong, too lean or bearing is going out. The head is about all that gets seriously hot esceciallyif you have it set rich. If there happens to be a lean run on the engien it makes sense that an uncowled engine would tollerate it more because of the extra cooling privided by the air. I run my 2300 on the Funtana 90 with a cowl and have just cut 1/4" slots in the head area that privides plently of cooling. I try and keep it rich because this large engine does generate much more heat than a small engine.

Status: offline 		Mosquitos have been flying here in MS this winter until just recently. I was out in January in short sleves and the mosquitos were flying. The mosquitos here can even cause a person to crash. You can easly crash if you are flying low and fast and trying to swat the pest and take you full attention off the plane. Once while flying the mosquitoes started biting and before I could land they had nearly drained all the blood out. Needles to say I didn't go back out to fly without mosquito repellant. I keep a can in the flight box at all times now.

Status: offline 		Ok, down to business. How does the Super Tiger line of engines handle crashes?? I have planted or crashed many OS engines and have lost only one due to crash damage. Well really I could never find an OS61 that I hit another airplane in midair. I looked for that engine for days but couldn't find it. Come to think of it I could not find several other items either (receiver, battery, servos, gas tank, and most of the plane). I hit a 120 size plane with a RCS head-on and the carnage was terriable. The other plane was totaled also and his engine had a bent crank. I was looking at my Super Tiger engines and thinking about that big muffler and wondered how it could handle a crash. I would not think the muffler would fair well in a crash.

I suppose the ST engines are about average with crash damage. The flimsy muffler arrangement on some ST engines might save the crankcase mounting flange from being damaged. Might.

I nailed a power transformer with a K&B .40 powered Kaos 40 in the early Eighties. Our field had no powerlines next to it for the previous decade of flying and then one day...

I did a split S to land (low altitude) and pulled out only to clobber the transformer. The transformer won the fight, needless to say, but the K&B survived because the 1/4x28 removable prop shaft stud sheared and took the brunt of the impact. The model looked pretty bad (outer half of left wing exploded), but I had it rebuilt and flying again in a month or so. The K&B .40 ran just fine after replacing the stud with a hunk of all-thread from the local Ace hardware store.

Status: offline 		Several of the crashed that I've had as resulted in bearig replacement. I trying to avoild buying new bearing, installed the crashed engines and continued to run them in other airplanes as soon as possible. Howerver it seem on most of these engines I later found that the front bearing had suffered some damage and it would begin to run hot. I believe as long as a person is very careful and watches the engine closely that it isn't a problem to do this. If you aren't careful though it could cost you by damaging the engine. Sometimes if I am testing a new airplane I always wait on rain to soften the ground. I have never damaged a bearing on rainsoaked ground. I have one plane I plan of flying before the summer heat dries the ground and makes it hard. Some soil (clay in particular) will get almost as hard as asphalt and will damage the engine more easily. Once I had to pry my 46FX out of the soil with a stick as it had imbeded itself into the soil deeply with no damage. I did however disasseble the engine to remove the soil.

Status: offline 		SigMan, I have seen that plane and it is a beauty for $99. The power from either engine would pull this plane. Really just depend on how much engine you need to balance out the airframe. I would think the 2300 would be a good choice but I don't know the weigh to your plane. I am impressed with several aspects of the 2300 like fuel economy, power 17X6=9000, and comes at a cheap price. Who knows you may be one of the one that don't even have to change the carb and even if you do it is only a few dollars more for a different carb. One thing for sure the Super Tigers don't have a liner to peel. Good luck and if you need assistance there are several on here with plenty of experience with the Super Tiger engies.

Status: offline 		Once I thought the Bruline airfilter would help keep dirt out of the engine if an engine did crash. Well it might help but if it is a headon crash the filter will be torn off so that idea only works if you have a glancing blow. I try to limit my crashing a no more than 3 a year. Once I have 2 crashes I will cut out all the foolish low level manouvers and fly more conservative.

Status: offline 		Another flight limiting factor I see from my personal experience that affects the way I fly is how many airplanes I have. If I have 5 or more I tend to fly lower to the ground. Once I got down to one airplane and boy did I give that bird a checking over before I took off and in the air I flew it around like a trainer. I am amazed at how much of an impact these little engines can take and come back and run.

Status: offline 		Once when I was flying at a club we used sand to level the field and I knew that could lead to trouble. Someone suggested that we use women's panty hose to filter the air. I used an o-ring to keep the hose over the carb barrel and it did stay on but I doubt that it did a very efficient job of filtering out the sand particles. Have any of you used panty hose to filter air?? Lets keep this to RC now, no wise cracks.

Status: offline 		I have seen panty hose used over the K&N type air filters to keep the large particles off the element and it works well. Fine dust will go right through the material though. Anything is better than nothing at all, so I would go for it.

Status: offline 		Most people seem to think their airplane engines aren't sucking in dust. I believe there is more dust entering the engine than most would believe. Recently when I noticed some small grass clippings in my throttle barrel is when I realized what was going on. The small particles of grass must have been thrown up on landing and drifted into the intake and stuck to the oily residue on the carb. I land on tall grass and the airplane stops rather quickly so if dust was kicked up it probally could be airborn and drift to the airplane. Also when you fire the engine up the prop could actually blow up dust that could be blown back tword the airplane. I read somewhere to never run an engine on grass or dirt. I guess that is why some fields have start-up stands. That way most of the start up would be away form most dust. Lets face it though in the summer months even in MS the dust can be pretty bad even in undisturbed air. Once when I was watching TV one summer morning the sun was beaming through my window and there was so much dust I had to close the window shade just to breath.
