I'm having engine trouble bill! I went put to fly yesterday (first time in 3 weeks) and my engine just in a hover kept bogging and when i tried to climb it bogged even more and the tail would blow out. What could be wrong?

Its probably rich Sam. Do you use your finger on the back plate to test for temp? If you can hold your finger there for 7 seconds its too rich. If you can't hold it there, its too lean. Its a good rule of thumb. When the weather changes season, you usually have to make a change in you needle settings. Give that a try and see if it helps. That's an easy way to tune your carb for flying conditions.

Time to learn engine tuning Sam! lol
I'm laid off this week and got allot of my chores done today. Hopefully tommorrow can be filled with some flying.

Engine tuning is as simple as putting your finger inside the back plate recess and adjusting your needle according to the engine temp. Just warm it up a bit and land, check it with your finger and adjust and fly a little more and repeat until its where you want it. You should be able to stand holding your finger there for 7 seconds without burning. You'll get a feel for where you like it and you are good to go. Remember if its too hot, its too lean, turn it out a couple of clicks. You won't burn up a motor doing it this way.

FWIW - I wouldn't claim to be a great expert on engine tuning, by any means, but the backplate thing has always seemed very subjective to me (depends on one's pain threshold, callouses on fingers, etc). I'm not even so sure about taking measurements on the backplate with a temp gage. Both of those seem to vary with engine size - i.e. the 30s seem to run hotter, for some reason (and are fine that way).
I prefer the approach where you drop into throttle hold, and do an auto - if the engine doesn't slow down quickly and smoothly, the low-speed needle is too lean (the only exception would be if the clutch is sticking). The difference in the sound is obvious, once you've heard it. The other sorta-test is a full-throttle climb-out (for the main needle setting).
Generally, you need to richen up as the temperature drops (and vice versa).
[Note also that for some engines (like a Thunder Tiger), the low-speed needle controls the mix up to about 3/4 throttle or so. On one of those, adjusting the main needle might not make any diference at hover throttle.]
That said, there are others on this thread with more experience than I, at engine adjustments.

Could be lean too. Colder temps will do that. Also look at throttle linkage and make sure everything is in good working order. But really Sam, nothing beats an experienced ear to help you out to teach you the proper way to do it.

Also check

Muffler on tight(fuel dripping of it?)?
Any raw fuel dripping of the heli near the engine/fuel lines/tank?
Fuel filter plugged?
If yes to any of these you have an air leak...fix it!

Too lean? Colder temps carry more O2. Oh he needs gas to deal with more oxygen. Could be the problem too.

Turn the high needle out 3 turns and see if it is better, if it is not and is worse go back in 3 clicks and go in 1 click at at time until it is better. Just keep track of how many you go in, but after need to check backplate with finger. Need to do climb outs to unload motor. If it gets better when you turn out the first 3 clicks then keep track of how many turns out you go. If you have to go alot tjen you may have a restriction somewhere. But before you do any of this put a new glow plug in.

Sam what Sonny, Paul, Brian and Jeff posted. Your stuff is tight and no fuel leaking, engine is warm to touch, start by opening the needle valve by 3 clicks.

Lol! I could really careless about the status thing. I don't watch but about 2hrs a week of TV. I would rather spend my time on the computer therfore I tend to rack up the post count really fast. I do like my AMA# though. It's 153764. No one ever questioned me at the funflys if I could fly when I signed in. LMAO
On another note, I got in a few hovers in the backyard today, not much room so hovering is about all that can be done. There were people at the park all day and for safty reasons I only fly there when it is empty. I could make it to the field but I did enjoy hover practice and getting used to FBL. Got my throttle curve back up to 85 now and a took my swash mix down to 45 from 50. It feels good. Can't wait to fly it(the 450) at the field. Plus I need a little more room to finish the mechanical set up on the tail.
Being my first FBL unit I have flown I think my gains may be a little low too, but I will wait to play around with that at the field as it is flyable right now.
Took the time today also to program the ESC on my sons 450 and go maidan it. Well it is a good thing I went FBL cause the elcheapo gyro is junk. The servos are junk too but work. I gave them a set of JR servos, one needs a gear set, but they haven't taken the time to repair and install them.
They meaning my wife and son, this is there heli together and I am only there to advise program and test fly for them.
I do have a backdoor though to get my son a well setup heli for him to learn on. My clone. Well you almost can't call it a clone anymore. The Align FB head went on it today. I have to go down to the LHS tommorrow and get bullet connectors for the Align ESC I got in the mail for it. Other than the tail, frame, bearing blocks and bearings it is pretty much an Align 450.
I'll set the controls up nice for him to learn flight on and let him fly that until their heli is flyable.
With all that said, Thank You guys and RR for all the teaching and tips. Without all the info here and the help and tips at the field there is no way I would have gotten off the ground.

PS. look I put all that in one post instead of 20 or 30
PSS. Thank You again!
PSSS. If RRmaster meant a free hat or the likes then I would care.
