Thought I'd update - as the new frame arrived
VERY Happy with it and it saves a load of weight over the CF one
Seems to handle some big crashes very nicely as the new frame is fairly flexible and just seems to absorb whatever you can throw at it
Only slight downside to it - the boot pins on the board are now hidden/obscured (I have soldered on a pair of jumper wires so flashing is less traumatic)
Also if changing the frames, just be cautious about the motors wires - if the motor drops too far down the tight fitting plastic is able to strip the insulation ...Had to do some minor repairs after being heavy handed replacing props
The frame is a good fit for the Chaoli motors - no slippage
The F3Evo brushed board I am using is a tight enough fit that I am not using any foam to hold it in place
The frame also has a nice flat top making a nice platform for my 3d printed cam/vtx mount with roll bar held in place with double sided tape
The battery tray is a really good protected fit for the Syma X5C 600 Mah cells I have been using - no more sketchy elastic bands!
The frame has built in little landing legs at the base of the motor mounts - and they work brilliantly at keeping the battery out of harms way (no more peg legs to shear off!)
With the lighter frame I have found it has become even more lively/punchy and is more than capable of indoor flips and being able to recover without fear hitting the ground
Glad I got the new frame to try out - can recommend it as an upgrade part for sure!
