E720 + Agusta A109 Power ?

[DenisFerrari]

Hi all, I'm at the point to start my next project that is the Thunder Tiger A109 Power scale helicopter.
I already have this beautiful fuselage new in the box and I would like to make it electric.
I know that fuselage has been projected around Raptor 90 mechanics (That I know very well since I use to fly a Raptor 90 3d I.c. That I love).
I'm looking for a Raptor e720 flybared kit ... D you think it would be the best choice ?
Also, my main doubt so far is about the length of the tail tube (from main rotor axis) compared to the Raptor 90 mechanic dimension ... Since I would not like to encounter big issues during the mech. Installation inside the A109 fuse.
I think that there should not be big differences since the E720 is a Raptor ... But I would like to have some more consistent information before to decide and buy such a kit.
What do you think?

Any kind of suggesting is Extremely well appreciated

Thank you all!

All the best,
Denis Ferrari
