Gas RC was a mistake !!!!
Is it really bad to store fully charged li-po's? If so, what is the best way to discharge them? I have 3 that way.
You could also discharge the packs by flying and then charge to 50%.
You can use the Hyperion EOS sentry for measuring the cells. I use the Hyperion for all of my planes because it shows the % of charge left in the pack. One of my buddies crashed last week because his receiver battery was dead. $25 meter would have saved it.

Will a Thunder AC680 work?

This was listed on hobbyparz website for the charger:
Lithium battery Fast and Storage mode[/b]
The smart charger offers additional Lithium programming. Fast charge reduces the charging time of the Lithium battery and the Storage mode controls the final voltage of the battery to be suit for long time storage.
Your frustration and experience are very good examples of why you SHOULD join a club. Many of the discussions and points being made on this forum over the past several days would be cleared up in 15 minutes or less with a good day at the club. You'd find people that will help teach you how to tune the engine (just reading about doesn't cut it), help you check over the plane, help you operate trims on maiden if you need it, extra parts in flight boxes to make quick repairs, and who knows what else.
The TT Pro 46 will run fine on the Cool Power 15. I have been flying these engines for several years, and they are absolutely my favorite engine in the 46 class. Once tuned, they're easy to start, reliable, and rugged. They're also easy to find parts for should you ever need to. I use the Omega 15 rather than the Cool Power, but that's a personal choice. Just make sure they're plenty of oil in the exhaust stream, and its not burned (should be clear).

All the guys at my club cant believe that I had not ever fly a plane before that... :
Trained on the sim extensively. Feel confident.
Started with parkflyers. No issues.
Decided to get a gas trainer, look at clubs and an instructor.
Instructor tells me...no rudder.....you wont even touch the rudder when you fly with me. Most guys and instructors dont use the rudder out here.
Want to buy a gas trainer and radio?
Park is where it is at for me.
Anyhow, Yearning, you are doing OK! What others here failed to see is the Parkzone T-28 is not a tiny plane, nor is it a trainer. It is a low wing tri gear plane with little dihedral. If you were flying the 3 channel cub, different story altogether. It is more difficult to fly than a high wing trainer, more prone to stalls, and not as self correcting. If you can fly one of those, take off, land, etc. then a popper trainer will be easy.
Sounds like you just need help on how to use the motor. I learned to fly with a sim, then a UM t-28. I then went up to an Apprentice and flew it out of my back yard with a nice take off, a few circles around my place and a safe landing. I also have an Eflite T-34 that is a 6 pound electric low wing PTS. I had my friend maiden it and trim it out for me, and I have flown it a few times before the weather turned.
As far as rudder control, sounds like you already have it, and flying in any cross wind, is NEEDED, especially in the Apprentice. On take off and landing a cross wind will spin that plane 90*, I put it in a tree the last time I flew it due to a strong cross wind. Of course the fin was cracked and not very stiff, so my rudder wasn't as effective as it should be, which is why I tree'd it. Where I fly there are obstructions on the flight line, like pieces of an A-26 and a navy jet fighter, but the biggest one is the barn. The week before it flew into the tree, I flew it into the barn while trying to learn the controls from right to left as opposed to left to right, and my left and its left were backwards. I was practicing approaches and was going slow, but it still broke things, and while test flying it after repairs I found the rudder was not working correctly. However Before my planes introduction to the barn, I had flown it on windy days with 15-20 MPH gusts and it's lack of weight shows, but using rudder kept it under control. I really didnt use rudder in turns, but used it in take offs and landings from the start. I also used it to do some crazy maneuvers in the air. At full throw it will tumble the plane wildly, and is quite fun.
You should have NO problems flying a popper powered plane, you just need to know how to setup and adjust the engine. If the club you join requires a solo, use your T-28, study how others fly then ask one of them to assist in getting the popper in the air.
Definately see if you can find someone you can develop a student / instructor relationship, that is definately the way to go. If not, be safe, find a deserted field, and take it slow.
Good luck! Let us know how you make out!
One of our clubs had a super instructor. Really a great dude and he could teach this sport to almost anyone. Then one year at our CHRISTMAS/election meeting he announced he was done. No More instruction. Was he mad? Was he burned out? No one knows for sure. It did cause a problem that was not considered. Each person that tries to instruct is compared to this super instructor. The old instructor was out this week. Yes he can fly and I mean fly anything with skill. It looks like he made up his mind to enjoy the hobby for himself.
Still it is hard on the new guys that are out there teaching when this man is on the line. The most important part is the other instructors don't bother the old dude. They just watch him as he goes about his own business. A good instructor is a true treasure to a club.
This forum is a true treasure to the sport. Everything from how much oil to club rules. Yes, there is a lot of instructing on this and other forums. When each of you take your time to share your knowledge it is like that old instructor. A true treasure!
kid at hobby store sold me 15% synthetic cool power............no castor
found manual for motor it says do not run in with synthetic you need castor
argh where are my golf clubs
and cool power is fine. .. and really on that motor on that plane.. break ins are great.. but ususally not needed. the motor will still far out last the plane..
so far:
the rudder thing.....when my knowledge of full scale flight contradicts this
and no castor needed....when the owners manual and my knowledge of breaking in race motors is no sytnthetics during breakin as it is too efficient and doesnt let the metal parts wear in....
The TT-Pro 46 isn't a racing motor. It doesn't need to wear to be broken in. Its an ABN engine (no rings), so as it heats up, the cylinder expands. More friction means more heat, means more expansion. Experience shows that these engines are best broken in while flying. Start it, tune it, launch it. It will last years. Run it on cool power, omega, or just about anything else.
For what its worth, I've had one on a pontoon plane. The engine has been completely submerged on many occasions. It still starts with one flip and runs reliably.
And if you're worried about the fuel, get a gallon of Omega 15 and run that. When its gone, use the cool power. These will hardly be the last gallons of fuel that you ever buy. When I was flying glow, I was using about a gallon a month.
Nothing beats stick time for gaining experience, and in a few months you'll be forming your own opinions and not worrying about what everyone else recommends.

I think I know who you, you refused to use a buddybox. You had no control of the model, I saw you try to qualify 3 times in order to qualify for a solo certoficate, each time you did not qualify, amd Isaw you crash twice. For the record, it is not an instructor issue, but that of the pilot.
