RE: HET F18 700mm span any good?
It is a good start edf. I prefer balsa over foam.
If you are looking for a super fast edf this is not the arf plane.
Have a build uder het f18 personalization.
The good things uses 3s 3200-3600 mha wich are cheap now days, a 500-700watt motor is more than enough.
Need some previus experience to build since it is not an arf as descibed.
Cheers
Juan
