Well, I dont know what to say, really , it seems like bad news on the build front.
Would I be right in summing up this helicopter as a really good design, poorly executed, with poor materials and second rate electronics?
I certainly dont want a heli that breaks down all the time, and falls apart all on its own. Goodness knows it will get enough thrashing when it hits the ground time and time again as it inevitably will.
Reading the threads of some of the other helis, eg the black angel, these models have their supporters who continually swear how great they are. This one does not seem to have this fan base.
Pity. It looks fantastic.
I have got both 4F200 and Trex 250. The 4F200 is easier to fly than the stock Trex 250, in fact the Trex is a very nasty demon. However, a Trex 250 fitted with a 3G FBL is much easier to fly than a 4F200. I really still cannot quite believe how stable it has become, but you are talking nearly $600 worth of equipment there.
I have only been able to have 14 flights with my 4F200, but in a shorter period of time, I have flown 125 flights with my Trex 250. Not only that, I have only replaced a pair of skids, a tail boom, a servo gear set, a pinion gear on the Trex 250. Whereas with the 4F200, I have replaced 5 servos already and a set of main blades. You should also bear in mind that spare parts from Align and clone makers are cheaper and more readily than those available than Walkera. For example, if you strip a servo, you have to buy a pack of 3 servos from Walkera. Wheras with Align, you only have to buy a pack of servo gears. Therefore, the long term cost are stacking heavily in favour of the Trex.
I have finally got some spare parts and I am determined to get the 4F200 right this time. At least, I have got a good idea about which parts is likely to fly off.
