| hey i got 2 gallon now in my rap30 so today after 2 tank i decided to attempt doing my 1st looping hehe.
Iam a beginner and my setup is quite simple: raptor 30 ,os 32, GY240, GV1 ,eclipse 7
I run 1500 rpm in normal and 1700 in idle1 ,i was quite comfortable with the heli and decided to try the loop, i make the heli climb a little then go Forward flight , level then pull elevator almost to full with adding collective to climb and go into the loop, all went good and when the heli was inverted i tried adding some negative pitch to help it not loosing too much heigh, once i did that and when the heli started to go out of inverted to finish the loop it suddently loose all power and almost went idle ,it went straight down fast and i managed to close the loop and get the heli level really close to ground !!
this one first loop it didnt crashed but the sudden loss of power frightened me !
i was thinking my GV1 put the engine to idle or reduced throttle alot i had almost no power in all the second loop half after in went inverted .
i was running idle1 with like 1700rpm and all was goo, i tested the heli before trying the loop to make sure my GV1 was keeping the throttle high when i go negative pitch ,by doing fast up and down climb.
When i was going down vertically the engine was not throttling down,at the first loop attempt when i wasz going down the gv1 was almost idling my engine and i had very slow descent .
Now what i made wrong ? could m GV1 put the engine at idle at full negative ?
On the 2 nd loop when i crashed, the heli almost made it but it was like 1 meter short u know and it landed so hard on the gorund that both frame and landing stuff broke ; boom was a little bent and need new one , no other thing damaged , after crash heli was idling standing like ready to take off but with broken landing gear 
What could have made the heli loose all the power after the 1st half loop?
It was like doing a loop in normal mode but without having a curve set to keep moror high when pitch going negative, iam bad at explaining all that but iam sure you understand something 
Thanks for any help , |
