| Post subject: | violent tail wag |
hi so maidened my goblin black thunder 700 t line today , and allthough flight was good except for violent tail wag when in fast forward flight . so violent that the tensioner for belt ,spun round back to its set up position. my heli has the following t line 710mm blades hobbywing 160 v4 esc bk 7002 hv cyclic servos bk 7005 hv tail servo xnova 4530 /500kv motor optipower ultraguard spirit pro 2 no dsmx sats dx9 tx heli is built as manual when programming spirit pro i choose gob 700 pre set in wizard . the only alteration ive tried is lowering tail gain in tx from suggested 50% right down to 20 % with no luck. ive checked and double checked tail mechanics , they are perfect . ive re done rudder end points they seem fine. ive tried headspeeds from 1900 upto 2100. at the moment i have rescue set to switch f on my dx9 using gain as activation. im going to put my gain back on flight mode so switch f will be just on /off for rescue . i increased the rudder from default 8 to 11 |
