120 SR TBI

[lanny haff]

I have yet another question for some one who would like to help a kindly old gent! Anyhow the problem is this I have 2 MSRs + 2 120SRs I got both the MSRs + 1 120 SR used I fly them a ll with a D4Xe Tx They fly great. 1 120SR is brand new. I haven't done anything to it but it doesn't fly very well. It does what I guess is toilet bowling It flies in a circle clockwise. backwards right, forwad + left. It doesn't want respond to the trans mitter trims + it's not been crashed yet to speak of . Anyone got any ideas of what Icould look for? Lanny

If my memory serves me correctly your DX4e does not have a memory so all your heli's must use the same settings, while the others may like the settings your 120 sr does not. There is a proceedure for initial setup, centering trims, leveling swash etc.
Just because your radio flies one heli great does not mean all helis will work with the same settings. My best guess is the heli needs a complete initial setup yo your radio or you need another radio to go with the 120 SR. This is why the higher end radios have model memories so the radio is capable of storing different settings for different models.

Lanny I cant remember if we Activated or Deactivated your expo the other day, having the expo activated can give a toilette bowl effect on some hellis.

What happens is because the expo deadens the stick at center it can cause you to chase the heli while trying to hover, make sure your expo is Deactivated.

This may or may not be your problem but it's easy enough to try..

I rebound it + made sure all the trims were centered. Now itflys like my 107s. Almost hands off hover. It's almost as nice as my Madhawk 300. Thanks for the help Lanny
