I've finaly finished my E7 that I bought from Paul I'm not going to pretend all went smotthly as it's given me nearly a week of issues but its now ready for its thrid maiden I think. IMG_0419[1].jpg
I had a whole host mate from a 1mm aileron interaction over full range of the pitch a couple of swash to servo rods that would slip on the rods without undoing that plastics super hard to thread.
Thats the heli issues mainly the other issues were down to shredding a set of tail blades whilst slowly spooling up the heli less main blades this was the esc soft start which is awful on the 130a commander & can only be fixed by an update of which the lead I had wouldnt work so ended up waitig for postman to deliver a new one.
The other issues were vbar related, whoever tells you vbar is easy to set up is lieing lol. I've done three now in three weeks & I cant get it right yet.
Thanks Rosco I may well need that help
I'm running 107mm swe tails on it & hoping to be able to get the head speed down to around 2k max whats my chances?

107's will be fine but if you are wanting to run a head speed at around 2000rpm max then you may wish to try longer tail blades to get the best performance.
Electric helicopters have much more torque than nitro helicopters which translates into a higher demand on the tail rotor system. Inadequate tail blade size or head speed can result in tail blade stalling. Once the tail blades are past the stalling point the belt will skip teeth and can potentially break the belt.
Here are some factors that can affect E7 tail performance.
1. Tail rotor performance is relative to your head speed.
2. When running slower head speeds 1900 - 2000 you should increase your tail blade size.
3. When running higher head speeds 2200-2250 you can easily run 106mm blades without issue
4. Heavy cyclic and pitch at the same time (ham hands) will blow out any tail. Adjust your cyclic and collective to meet your collective management skill level.
5. The heavier your helicopter, the higher the disk loading. The higher your disk loading is the harder your tail must work to counter act torque. Run appropriate size tail blades if you are running heavier batteries.
Here are my recommendations based on head speed.
Head Speed------Tail Blade Size
1900-2000* * * * 110-115mm
2150* * * * * * * * *110mm
2250* * * * * * * * *Rail 106mm (they have 30mm cord for nearly the entire length)
Do not let your tail belt slip! It will eventually break as it is too much trauma for any belt to handle.
