Review: Blade270 CFX Bind-N-Fly

The Blade series of helicopters exemplify simplicity and user friendliness. Due to increasing popularity and technological advancements, Blade has integrated flybarless systems into several of their helicopter models. The 270 CFX sits between Blade’s 180 CFX and the 300 CFX. The 270 provides a more optioned out model compared to the smaller 180, steps up to 6S power, utilizes a pro-level bailout enabled flybarless gyro with the AR7210BX and gives a bit more presence to handle the rigors of flying outside. The 300 CFX is less costly, but is actually a bit smaller, particularly in the main rotor diameter and runs on 3S and doesn’t have the bailout capable AR7210BX gyro. I feel the 270 CFX is blending the portability of the micro/sub-450 size with true “pro” level capabilities of a 450+ sized model.

 

WHAT’S IN THE BOX:

This model comes packaged in an attractive cardboard box that doubles as a carrying case. The model is nestled in Styrofoam and is easy to pull out for quick lunch break flights. You get the model, of course, and some basic tools. You need to purchase the flight batteries, charger and a DSMX compatible radio transmitter separately.

SETUP

The instructions for setup are meant to be very simple. However, due to the inherent complexities of a collective pitch FBL model and that the target consumer should already have some flight experience, I advise going through a more traditional setup process to verify the factory got it right. I had a Castle Link adapter on hand so I could run through the ESC’s programming top to bottom as per Castle’s instructions. The end points for my radio did wind up slightly different from the manual’s suggested settings, but not enough to have caused an issue had the manual been followed explicitly. I did have to do some digging around on the internet to figure out the main gear tooth size, but I did get it figured out and set up the SetRPM governor function accurately. I also dropped the Initial Spool Up rate down, along with the Motor Start Power. I personally prefer a slower start up so I have a few more seconds to get focused on the model just before lift-off.

Once the ESC was bench ready, I bound the model to the radio with my sticks in their fail-safe positions. This saves the new end- points to the fail-safe mode. Once that was complete I moved to the FBL gyro. The AR7210BX included with this model is at its core a fantastic, easy to use gyro. I use the precursor (AR7200BX) on several of my models and love the simplistic setup and reliable performance. The unique feature of the 7210 is that it now incorporates a SAFE bail-out function. Technically, this gyro has five modes of bail-out operation, but here is where a rather unfortunate factor crops up. Blade locked out several of the setup selection features of this gyro. One in particular is the only SAFE mode available is “Bail Out Rescue Mode with Collective Pitch Control” and you cannot adjust Setup J for the 6 degree pitch learning. If you’re inclined to adjust the FBL settings and unlock all of the features, you’ll need to purchase the BeastX USB interface cable/adapter (SPMA3030), download the StudioX software and pay an additional $105 for the unlocked firmware.

After getting over the bit of frustration about not being able to go into the gyro setup to verify it’s all correct, I bound the model again to insure my fail-safes were all properly set since I had changed the ESC EPAs. Before it went back into the box, I verified that all the controls worked in their correct directions, the flybarless gyro was compensat- ing in the correct directions and the digital trims worked properly. Everything checked out perfect. I charged the battery at 2C and it took 20 minutes to fully charge. Internal resistance ranged from 8.8mOhms to 11.1mOhms. It was time to drive to the field and throw the 270 into the air and see what happened!

 

Spektrum S6240RX digital servo & receiver unit

Coming soon from Spektrum is the S6240RX digital high-speed servo and receiver unit. The servo itself features the durability of metal gears and is capable of delivering down to 0.08s transit times along with 15.0kg-cm of torque. The built-in SR2010 2-channel receiver gives racers a sense of response that feels almost instantaneous, especially when used with a DSMR radio capable of 5.5ms transmission. Both the servo and receiver are housed in a 20mm case that measures 30mm in hight which is in-between a standard and a low-profile servo. The servo and receiver unit is best used for 2WD buggy applications but may also suit many other classes.
