Raptor Roll Rate

I was a bit dissapointed in the roll rate of the stock Raptor paddles. I went to the KSJ paddles and the rolls and flip rates really improved.
(I sanded down the leading edges to blunt them slightly and run then in the front holes) Rolls were very tight afterwards and tracked well axially, not a barrel or corkscrew. Hover and FF were fine too, not twitchy at all. They were $7.00 a set. Also, if you run a higher headspeed your cyclic will be more responsive. I bet that 240 will hold with a higher headspeed to get more tail rotor response as well as the cyclic response improvement.

Those Raptor like a high headspeed for 3D. I run 1900 RPM in IdleUp2.

headspeed

furyflyer,

I am running a Raptor 46 at 8.5/1 ratio, so at 1900 I'm at 16,100 RPM. That is about the same as 1750 @ 9.5.6/1 stock ratio @ 16,730 RPM.

I have seen a few guys running 2000 plus on a Raptor 30 with 30% nitro and not have a heat problem if they run a cooling shoud over the head.

Rolls

Well I have flying my Kalt Baron for about 10 months (with two months off for repairs) ( NO SIM ) Anyway Two weeks ago I did my first loops, Looked like (e) but they were loops, Today I did the first rolls. And somewhere I read that rolls are easier I Agree. The Baron is so smooth and Big (relatively) and I flies like it is on rails, I make really nice rolls. I will keep working on the loops the make them more conscentric, But I just wanted to say thanks for the imput on this forum about aerobatics Looking forward to 3D in the future.

also

the 240 gyro is a good gyro....I have one in a raptor 30 and can tear the sky up with it.....also it holds well in moderate backwards flight..to answer your question about the rolls (and not the gyro)...make sure you are not inputting any elevator when moving your stick to the left or right in doing the rolls...also, you don't need to go but about 3/4 stick positive and negative when doing the roll. when inverted, if you have too much negative it will try to climb and will distort the roll...go a little easier on the collective..

I found that I could do better roll's when I was flying with no gyro at all. I now have 401 combo and find that it takes some finesse to get a good roll. Too much neg pitch or heli not level and a cork screw in the result. Don't think It's your gyro.

Put your 240 into piezo mode when you do rolls. It will track better, if your in HH mode and you enter the roll kinda crooked, the tail will hold its position and it will just mess things up( corkscrew, sideways at the end, etc.)


BTW, I run about 1950 headspeed on my Raptor 30, it likes a high headspeed.

Guys you need to stop filling this guy with crap he doesn't need. I am running a Telebee 701 with a Htiec 525. This thing will holds as well as the GY 240 and by setting the servo end points I can pyro faster than most can even see. I am not saying this to be ignorant or anything. But the stock Raptor tail blades a fine for the heli. I upgraded to bigger ones a while ago and all that caused was more slop into TR system and I had to cut my gyro gain in half just to get control of the tail.


You don't need to go and get a $300 + gyro and bigger tail blades to get control of the tail. The problem that I notice alot with mine is that I have the sticks on the Tx to loose. So that when I increase and decrease collective I am also pushing a little bit of TR at the same time. This is one thing to check.

The other to check is watch how fast you are going throught the loop. Normally no matter how good or bad of a gyro you have, if you go through fast enough the tail is going to follow the bird. If you are going fast enough throught the loop try doing some backward flight and see if the tail wants to swing around.

Don't go at this full stick though. I learned that the hard way. I can fly almost full back on non windy days. If the tail wants to swing around will doing some moderate backwards flight. Increase the gain a little. Also before going out check to see if the entire TR system has any slop in it. Normally the gyro will beat the heck out of the TR servo and you will have to replace the gear train every so often to keep that tight.. But also check you ball links. The one on the servo seems to always be the most problematic.

If you still can't figure this out. Try doing some fast forward flights. And see if the tail does the same thing. Then while in FFF increase and decrease the collective. Make sure you do this up high though. If the tail doesn't sway to one side in FFF but does when you do the FFF bounce, then you still have a problem with the tails electronic system OR you are moving the TR stick while changine collective.

Try overdriving the tail, to do this put the gyro in normal mode and set the ATV's so that you servo buzzes like crazy at the ends. The reason that you do this is because the gyro subtracts from this when making corrections and it eventually makes its own decision on where the end points should be. then throw it back into HH mode and push the stick a little bit. If the servo moves to the end faster then your done. Go test fly it.


If none of the above helps I am going to need some more info.

A good test to see the holding strength of a tail is to enter fast backwards flight and violently push forward collective and flip it. The other way is to do a tail slide and build up lots of speed and then violently push forward on cyclic and adding almost full collective. Then you'll see if you gyro and/or tail blades are holding well.

You are pushing VOLARE to his outer limits!

Make sure it is not pilot error control stick before go further in to gyro. On the bench turn on Tx,Rx do a flip, roll and looking at your swash plate not at your finger, do you see the swash move level with single axis. Now train your finger to do a straight roll , you 'll be happier!

........your gyro just drifted into the wrong subject, just like a bad roll!

Volare,
You sure got alot of info on this, glad you got your problem worked out. Tail slides are cool aren't they? I would like to add one final tip for you. Next time you do a roll try it going downwind and at a few degrees dive, you will come out smoother and either be still slightly diving or level. They look much nicer than the ones that lose all momentum due to a slight rise in nose through roll. That's the way that works best for me.

Fingers

Get someone to watch your fingers I am assuming you are using collective to hold a level line and without knowing it moving the rudder.
