Trex 550 / Gobin 570 bogging on rainbows

[chrisleematt21]

I tried my first rainbows tonight and they weren't too awful, but I did notice that the helis were bogging when changing direction. The goblin wasn't too bad but the trex was.

Is this just down to bad technique or are there things which I can change in the setup to help?

Too much pitch & not enough headspeed? I run +-13 degrees on the goblin with no issues and power in reserve. Try increasing the headspeed a little at a time if your pitch isn't overbearing. Rainbows are long and smoothe and a precursor to tic tocs you shouldn't be bogging the motor really. If it's not either of these look to your flight pack? What is your setup on the Goblin?

I think im already running the max HS according to the CC gov any way.

Im running
+-12
HS 2382rpm IU2 CC Gov @ 95.8%
CC Edge 120 HV
Xnova 4025 1120
VX1n (Heli Style 3d all defaults)
Haiyins 6s 5000mah 20 - 30c
23T pulley / pinion

CC Setup
Gov Gain 25 (Medium)
Spool up rate 8 (High)
Headspeed change rate 8 (High)
Motor Timing 3
PWM Rate 12khz

According to the CC log my average HS is 2608 and the max is 2644
Average amps are 51 max is 103

How low does the head speed go during the moves?

2550 ish I think. Looking at the graph from the log.

If my headspeed is set to 2382 how comes its averaging 2608?

[james_2k]

im not sure what qualifies as 'bogging' but i dont think 50 drop from average is too bad?

er, i have no idea why the rpm is over reading though!

Tbf at the time i was going by the sound it was making and the lack of power feeling. Probably should have looked at the log first!

i understand, there will always be a slight noise change on reversals etc especially on a reactive governor, maybe proactive ones handle it better im not sure.

either way go 12s

I already have the investment in the batteries for 6s maybe next season I will consider 12.

Its quite a big noise change on the trex

[chrisleematt21]

It could be, they definitely struggle to get back the other way, more so on the trex. I was wondering if it was me but as its a lot worse on one heli than the other im not too sure.
