I can't get a tail configuration for my SAB Mini Comet, when it works with 90% motor power. With lower gain the tail is stable at high speed, and only occasionally starts to resonate badly especially after a long dive into the wind, but I can't fly a negative backward turn, the SpiritPro cannot hold the tail heading and all hell breaks lose! Rescue function is pointless, since the tail gain is to low, the tail cannot be held in position. I can increase the gain on the transmitter, and the negative backward turn is just fine, but now the tail resonates wildly even in horizontal flight without a dive. Either I fly fast or I have reliable heading lock, but I didn't find a configuration to get both.
Servors: MKS
Tx/Rec: Jeti
FBL: SpiritPro
Configuration: Common Gain = 1 - Gain Modifier in the Tx = 7% for high speed and 20% for reliable Head Lock (Controller Output Level tested from 85% up to 90% in 1% steps - result is marginal better at 85%)
The SpiritPro FBL is working as intended at lower Controller Output Levels, but it's not exciting to build a hot rod MiniComet with high quality components only to limit the power output to avoid problems with the tail or the heading lock.
Any suggestions?
