Hi All     Got a HOR App/Cat 32in  Specs  2770kv xl motor , Suppo 125amp e.s.c ,  38mm prop. Been useing 14cells 3300 NiMH G.Ps .  Not bad at all   Tryed  Lipos  4s 35c- 3s 35c both 3000mah. Programmed  the e.s.c  (To the Letter !)    Total C*ap  not even 50% compared to the 14cells    Been useing B/L lipos on & off for about 2yrs now so know a little bit The Lipos were fully up & balanced 4.10v per cell  Any Ideas? Heres a link to the program sheet if it helps

Hi
Just a quick thought answer may help stir the experts on here, but I may be missing something here but the voltage on the 14 cells is approx   14x1.3=18.2v and the 4S Lipo = 4x4.2= 16.8v
Hope some experts can come in on this.
Regards

Sorted now  Prop set to low   Just of interest 14cells = 966 grams   6s=330grams  4s=210grams  Little bit of a difference  So needed to adjust the strut/C of G ect to sort it.

[John Mk2]

[Drkomen86]

well Im having a poblem with a model of mine, wonder if you can help.
Im running a flexi-shaft with a brushless motor and one of thos red plastic UV joints, problem is that the joint vibrates and after a while it will just fly appart 

Also for no reason it flipped over 

any ideas people?

[John Mk2]

Easy A small  length (2cm ish) of garden hose soften in hot water then slip i )t over the U.J  A cheap fix. But do try to go for a solid coupling if you can MUCH Better  

[Drkomen86]

I hav put a little nitro exhaust hose over it so I can test it but it still seems to vibrate a little.
What type of coupling do you recomend and do you have any links?

[John Mk2]

Have a look on here  A solid for flexys / A u.j for solid shafts.

Oh & make sure motor/flexy shafts are lined up (& lubed) well or you will wear things out VERY Quickly
