Ok. first question, I've broke in my engine (OS 46 LA) It made mess all over the plane spitting feul all over the place. I've now got it running at its top performence and I still have to wipe the plane down after every flight, not as bad but it still makes a mess.. Does this stop? or will it always make a little mess?
Yep, some 18-20% of your fuel is oil. That oil has to go somewhere, and that is somewhere outside the engine. Drats! [&o]
Second question. yesterday I went flying and on my second flight of the day the plane died and I had to land dead stick. (thought maybe just a stall) restarted plane and took off again, the plane got up about 15 feet and dead again.. I checked the gas and made sure it was flowing with no blocks in lines. I checked receiver to make sure all connections were good. It felt like the battery line was loose. Would that have caused my problem if the plug was loose and shorting out? Last question .. About how long do most receiver batterys last? how often do they need charged? thanks for any help you can give..............
The 2-stroke glow runs on fuel and air, not electrical. So the receiver will not kill your engine unless you have a receiver that goes to idle for fail safe with low battery. BTDT! First time I did not pay attention, just paid for new plane!
Full battery failure shortly after the second "idle."
You show to be in OK. There have been significant WX changes in the past few weeks. When it gets cold, the engine is sucking in more air molecules. It needs more fuel, so the NV has to be adjusted accordingly, especially if you were running, "top performence." Otherwise you go off lean and can lose the engine when you power up, or shortly thereafter.
Unless I have a larger battery, I quit after some 50 minutes time on batt. With a loaded check, I may do 1:20, depending on # and type of servos. Even on 40 size models, and especially larger, I mostly use 1300-2000 mah bats. or 2500 mah Lith. Ions. That provides all the time I need in a day's flying for any one model. I don't worry about a couple ounces added weight. It's always strange to me that some will place 3-6oz. in servos at the aft end of a machine and then have to add 12 to 24 oz. weight to the nose to compensate, [:-] but they won't add an oz. to structure even to keep the engine from breaking the firewall off. Weird!
Batteries should be well charged within the 14 hour period prior to any flying session. Unless you are using Lith. Ion, it is a good bet that within 2 days a lot of mah will dissapate on NiCads or NMHs. Yep, it takes a lot of both post-flight and pre-Flight to keep things working.
Good luck!
