Default pitching down in fast backwards flight....

Guys... today while flying the rappy, I was practicing some really tight circuits in Fast backwards flight. What would cause this thing to want to pitch down tail first when I realease some down pressure on the stick. Yet, in FFF the thing has no pitch tendancy at all. Could this be old dampers ?

Wow that could be a lot of things, how is your CG? What is your pitch range? I know that a lot of people have had problems with pitchy raptors in forward flight and backwards flight and it has been due to a number of different reasons.

Bet its less pitchy in backwords flight than say..... your airplanes!

This can be with all helis not just rappys... things affecting could be cg, tail fin, dampeners, ect....

if you are a bit tail heavy and have some trim to compensate in a hover, it forward flying it will pitch up some, but you dont notice it as bad, then backwords flight, it'll pitch down but be alot more noticeable.

Try taking the TT sticker off of it. That has sometimes been known to help. j/k

You're right, I didn't mean to imply it was raptor specific - in fact I had the same problem with my Evo, it turned out to be a cg problem.

Here is a random suggestion if the other ones don't fix it- check your paddle alignment. Make sure they are collinear to each other and parallel to the spindle.

It is also possible that you have the same pitchiness in FFF but you brain is correcting with no conscious input. Your backward flight might just not be up to that same level yet.

Try putting the heli in FFF with full throttle and actually let go of the right stick to see what happens. Try it again in FBF.

If you still have a horizontal fin at all, lose it.
It requires a bit of down trim to counter the Horizontal fin in FFF, now in FBF the trim is causing the tail to drop AND the horizontal fin is now also pushing the tail down, so you get a double whammy.

What everyone else said is also very likely a contributing factor, It could very well be a combination of all of the things mentioned so far, and a few we have not thought of yet.

Swartz, you know if Fassbinder is back from Taiwan yet ? I'm gonna get with him to get this thing dialed....

I wasnt serious about flying helis up until about a month ago, as I used it as a diversion, and novelty.... Now its all I think about.... I'm addicted.... In fact I might even think about trading a 35% for a fully set up 90 ship....

No, "Skittles" is a strippers name :9:

Carrera means race or more importantly is the nameplate of my fav car... the 911
