RE: 150 meter rule.
I havent tinkered with it in a few months and havent completly sorted it out but if memory serves using altitude from the pitot gave decent GPS 3D mapping with the Eagletree. I did have to move my pitot all the way out to the wing tip to rid what appeared to be false readings from pressure created by the propeller/fues??? using you smart phone for way points or verifying Google earth can also be a useful tool. FWIW coming from close in 3D type flying to pattern I have had a problem with 150m +. I feel comfortable at 100 but I fly intermediate so what do I know

RE: Batteries running-in and swollen batteries
I charge at 1c then discharge to 3.75v at 1amp 4-5 times. by then the cells are balancing well (like .000). then I fly the pack kinda easy for the first couple of flights using 1/2- 3/4 of my normal flight time then use them normally. this has worked well for me after 6 years of electrics with long service lifes on anything from TP's to cheapos. over discharging is the only definitive cell killer I have found so far or running a pack that doesnt have a high enough "c". the rule I use is my max current should not exceed the advertised continuous discharge rating and preferably 80% of that. If the cells arent real happy at the end of the initial bench cycling i dont expect them to last long

I have one of their A50 outrunners in a heli. the can temp goes to 190deg in 5min. I dont even want to know what the core temp is. I have had it apart and it looks brand new. They use some bad azz adhesives in their motors

RE: How hot is too hot to fly?
I have always used outside motor temp as an indicator but have found it can not tell the true story. here is 2 snapshot of a test flight showing amps, airspeed, and motor temp taken from a sensor embedded in the windings. the other pic is rpm and temp. the intersting thing is the full throttle upline followed by a downline at 330sec can build heat quick. outside can temp was less than 100deg after this flight. this data was in 80deg weather. I think I'll check it next time out in the 100deg heat we have know

Silva. I get 9 min on a 4200 8s pack discharging to around 70-75 using CC 100 and Xoar 18x10 prop but different motor (300kv) than you are considering. I think you can get atleast 12min on the 5800. obviously depends on throttle usage, etc though

RE: Repair stinger on carbon fiber muffler
The muf is probably made with bismaleimide (BMI) resin which would require steps that Wyo stated above. the only solution I can think of is to make some type of mechanical repair like a aluminum flange with screws or something. as a last ditch you might try a high temp silicone adhesive (like you get at the autoparts store), scuff the surfaces and make sure they are clean. this will provide a flexible joint that may help

RE: Sukhoi Su-26
Looking at your other topic does draw some concerns for the type of flying your interested in with this plane.I have experience with 2 planes in this size range,a QQ yak 72" and a 3Dhobbyshop 72" 330 SC extra. The Yak weighs 11.5lbs and the Extra- 9lbs 13oz with my lightest setup and 10 1/2 lbs with the heaviest.. The Yak has about the same sq" of wing as the Suk and the Extra is a little over 1000. the Yak has too heavy of a wing loading and wing rocks. It is alot of work to 3D too. The Extra is a great at 3D but is noticably less floaty at 10.5lbs and will snap out if you pull too hard with too much speed. If I was going for the Sukhoi I would make sure it wasnt over 10lbs. It will definetly be way different than a foamy. Gas will be lighter than electric usually so I think thats a good start.I learned some hard leasons letting some of my planes get too heavy. they just arent fun to fly. Also I have found that SFG's when designed correctly can add alot of stability to a wing rocker (like in harrier). I have come to belive that the best flying models are 42" or smaller foamies or a 100cc. Everything in between just isnt as much fun

RE: Servo Mounting Questions
My opinions on 1 and 4- 1- I have spent a great deal of time understanding and perfecting geometry on my setups (obssesive). on a set up like the elevator where the horn and servo arm swing in the same plane pushrod length has no effect on throw symmetry assuming the rest of the geometry is correct. on a perpindicular plane set up like the ailerons excessive angles from short pushrods should be avoided. a longer pushrod also affords less wasted force, less angle error and generally speaking is easier to setup for throw symmetry (if thats what youre after). an extra couple of inches of carbon tube pushrod length adds a negligable amount of weight too. There are more important factors to linkage setup than pushrod length and a lot of "rules of thumb" that are just not true. 4- the rudder may require most of the servos capacity but the typical twin servo elevator or ailerons having low friction, with the typical throws and proper ratios will likely never need more than 1/4 of the servos capacity.

RE: Prop questions for an electric noob....
the thicker airfoil for the gas prop kills the performance on an electric. being that they are heavy also produces a nasty amp spike on instant full throttle.I have hundreds of dollars in gas,glow, electric, apc xoar,master airscrew, bolly, etc etc that I have tested on several "e" setups like yours and the xoar "e" has always been the clear winner in static numbers and Ive never been dissapointed with them in the air.

RE: Ideas for an intro pattern class
If part of the objective (if not all) is to increase the popularity of pattern I have some thoughts. although not really geared towards the absollute beginer It is what I might find interesting. I started flying fixed wing about 4 years ago focusing completly on 3d type flying (dont stone me) after about 4 years of heli. All you have to do is frequent one of the 3d forums and see the popularity is exploding for that type of flying. After tons and tons of flights and learning most all the fancy moves I began to realize that an important part was missing and that was the precision control which also allows the flow of one manuever to the next. I think many pilots like myself realize what I have and many could be persuaded to. These types of pilots are a huge resource of potential pattern flyers. Problem is that the concensous is pattern lacks the excitement so there needs to be a way to introduce that excitement while at the same time blending the precision type manuevers in and generating interest for them. So I would say introduce a "freestyle" segment into the "club" routine. this way guys will be able to showcase some of the things they can do well and provide some motivation for the things they cant (pattern). I am struggling through the intermediate sequence and just trying to increase the accuracy of basic manuevers but I love to cut up and do rolling loops, snaps and alternating rolling circles and have a real tough time sticking to the sequence (discipline). for me, stick movements- no problem, accuracy and timing-problem. I'll bet this holds true for many of the 3d guys. I'm confident once I start to get a handle on the precision that I will excell quickly and am beggining to understand the fulfillment of pattern. To increase the popularity of pattern one just needs to make the stick bangers realize this too. stop being pissed off at the stick bangers and invite them over
