The exhaust side of my Raptor 50 Titan keeps wearing the guide pulley after every flight it has worn the bottom flange off, has anyone had this happen to them?

Classic symptom of tightening the boom without loosening the fin clamp, it puts a downward bias on the boom when you pull on it and causes exactly what you descibe.

Also a classic symptom of having a bent boom.

I did this twice, destroying 2 side pulleys before figuring this out. I almost made the same mistake again last weekend while adjusting my boom in the cold weather

How come it is only wearing the one side? I guess because the way the belt is twisted, this side is further down than the other. Thanks for the help everyone, is it necessary to replace those pulleys with the aluminum ones?

I think it has something to do with how far the belt is from the pulley. On the right side, it is pretty close to the drive gear so there isn't much room to move up or down. On the left side, the belt is coming from the rear pulley in the tail case so if the boom is slightly bent, it is pretty easy to rub the bottom of the guide pulley.

After destroying my second pulley I switched to the metal pulleys.

Speaking of cold weather, as you can see I am from up here in Canada so our season is pretty short for the summer time, I do fly outside in Minus 5-8 degrees Celsius so how tight should the belt be before I go out side or should I tighten it up outside before flying. I have only been flying for three months and can not get enough air time. I am inverted and working on Tic Tocs as we speak so I want to make sure the heli is set up properly, any info is appreciated.

Tighten it after you go outside and the heli is in the cold weather for a bit. My tail had somewhat tight tension at home but it became extremely loose when I took it outside this past weekend in 28 degree weather. The belt became so loose it was skipping teeth.

I will keep that in mind, thanks what blades are you using on your 50 and have you put any upgrades on it like a new head and such.

I fly the G-Force head. I have a few sets of blades I switch between. They all work pretty well, but I have had problems with the Vs woofing. I have heard switching to leading edge control can fix that problem though.

You can get metal pullys, quick uk makes them but that wont "fix" the problem. The stock ones are fine, heck they may be the only original parts left on my first V2 raptor.

Once I realized what I was doing wrong, I haven't had the pulley problem again. I still run the plastic pulleys on my Raptor 30 and they have been fine for a few gallons.

Sounds good, I will test it out once more and make sure to loosen the tail clamp, and see what happens, the reason I ask about upgrades is I just ordered an Quick UK head for the Titan so I will see how well it works.
