This little heli looks a bit like an s107 but is physically smaller...and simpler in engineering I think. the tailboom is shorter, as are the main blades, and the canopy, although nearly identical to a 107 in side prifile, seems narrower... and lacks the rectangular opening above the 'windscreen'. I won't have a real 107 here for comparison till tomorrow.
The side frames consist of one metal peice on either side that is bent to form the neccessary shape required to house and connect it's 'innards', whereas the 107 uses two, connected by plastic bits and screws.
The little IR reciever thingy (technical term), is mounted in the centre of the belly pan, not hanging off the rear like a 107. No issues with reception flying in front of a big LED screen television either... although my daughter complained that while I was flying... the TV remote wouldn't work!! LOL
The BIGGEST difference is in the gear system, in that where the 107 has a series of gears to transmit power from the motors to the respective shafts, this 'copter has one very large gear connected to each shaft, stacked on top of each other, and are direct driven from the motors, which ae mounted similar to the 107-- one forward, and one aft of the main shaft. This is more along the lines of the bigger Syma, and other heli's.
I have noticed there is quite a bit more 'gear whine' than a 107...noticably louder, but not as bad as my bigger double horse with the same gear layout, but very similar.
Time will tell if this gear layout, in this size, is better for motor life!
My only concern at this time is the lack of spares beyond blades and balance bar for this heli. RED 5 shows no circuit boards, motors, gears, shafts... none of the things we would need to keep them flying!
Oh, Im getting eleven and a half minutes flight time on a 50 minute charge... and that's with two annoying red anfd blue flashing LED's in operation! (Time for some wire snipping!) You can turn off the forward white one from the controller.
Five flights so far, and the cats here, although interested, have not attempted to 'bring it down'!
This house is smaller than my 'flying space' (aka living room) in Canada, so haven't been able to 'stretch her legs' yet. Massive IKEA book case bisecting living and dining room is quite imposing and a hazard to aviation
Oh...The controller also has a spring loaded throttle...that was an easy fix!
Cheers
