hello John, is it ok if i ask a question on your thread?
I am posting a question for a friend. He has a DLE 55 R, and he purchased the motor brand new, this past summer. He has it in a aeroworks extra, and does mostly sport and IMAC flying. HE has over 100 flights on it.
He has recently done some changes.
bear with me, and i will get to the question.,....
the original muffler has cracked three times. he has re-welded it, and even the OHS has sent him two replacement mufflers as well!!
forgot who it is, but i suspect the person from VVRC.
all of them have cracked.
ok, he just recently purchased a JTEC muffler, during the winter.
and
we have been practicing IMAC, and on long down lines
the motor would
hiccup!!!
so, past 3 weeks, we replaced the clunk with a felt clunk from Home Depot lawn and garden department.
ok, what happened today, and please forgive me for being so long winded http://www.GiantScaleNews.com/forums/images/smilies/wink.gif
today, he got a dead stick!!!
bad news
but no damage to the airplane, besides a cracked propeller.
this is what we happened.
while we were practicing, (he has a high idle, turned on immediately upon take off), everytime he came out of Immelmann, and lowered throttle all the way to make the spin, the motor, once the airplane broke, would sound like it was about to turn off. on the way down,he would be bursting the throttle.
eventually, it died on him.
ok, we changed out the prop,
and on the ground:
1. transition from idle to WOT, great, no problem.
2. idle is ok. (hold a minute here)
3. ok, if WOT, and drop throttle immediately down, then with stick all the way down, it still has a high idle, like over 2000 rpm, then over a 20 second period, the idling comes down slowly, then to a rough idle.
4. if at this point, he punches it, it will transition great to WOT.
anyone have any ideas of what it could be.
he has a CM6 spark plug, he just changed out as well. ??
also, i checked his throttle servo, and when he brought the stick down, the servo did the same.
