They have EXCELLENTcustomer service...Max always responds to pm's and emails very fast...he explains things in great detail , sells quality products at reasonable prices, and LISTENS to his customer requests and tries to fulfill them. EPP Buddy is another quality retailer, always avaible, responds to all msg's and emails, even answers the phone if called ( Big plus).
And speaking of customer service, Quantum Hobbies.com is another great supplier. I purchased my first ZTW speedo from him for this plane, and had some issues getting it programmed.( my fault as it turns out..sometimes " experience" bites you in the butt) Issue was I couldn't get the speedo out of soft start up.Long story short, I hadn't properly calibrated the throttle, so the speedo wouldn't take the programming info from the card. Seems the calibration is sensitive to when the throttle is moved back to zero. The procedure is, Tx on, throttle high, plug in flight pack, listen for 2 beeps, immediately move throttle to zero ( speedo will produce 4 double beeps, you have to drop the throttle before the second pair of beeps or it doesn't take it). Once that was done, programming card works fine. Let me tell you, this thing now has monster punch and full linear control. Punch outs are gonna be a blast with this speedo.
Just waiting for the weather to break to get this bird in the air...shooting for Sunday for now.
