||Update to my previous review. A no-hassle contact to the E-Flite customer service. I received my tail motor free of charge. After the facile installation, my Blade SR flies good as new. A 5 minute phone conversation and 15 minutes of wrenching. No harm, no foul... -//- I would characterize myself as an intermediate pilot with experience with Blade CXs, Blade mSR, and an Align 250. I picked one of these up a couple days ago as a docile outdoor companion.
I've been hovering the SR in my 20x12 foot basement due to rain and cold weather. It was stable in hover with minimal trim. Some tail wag was present and was planning on adjusting the gain.
5 flights in with about 25 minutes of airtime. The tail rotor began to go. I notice uncorrectable counter-clockwise tail spin and immediately landed the helicopter. Luckily, no crash. I read about other pilots with "tail motor burnout". Some with loss of control, crashes, and damage.
So, the SR's level of components are a good bang for the buck. However, the tail motor quality is suspect. If it wasn't for the ail motor failure or failures, I would rate the SR a 4/5 to 5/5.
But... My final rating is...
