I woke up this morning and started working on the HK450GT that @Paulster2 sent to me along with my very first helicopter, the Razor 450. I already had the plan on taking all of the electronics out of it and putting in it what I had in my SE V2.
In the HK were a full set (4) of the tried and true MG90S servos which in their day were about the best servo you could get and still save some money. At my request he installed the Dynam Razor ESC and motor to save some money in this very expensive hobby. Those two are going back into the Razor. But not before I replace that extremely soft pinion which is about wore completely out. Paul also purchased a Turnigy Tx and in the heli was the HK-TR6A V2 receiver which I will be replacing with a receiver that I need to do a review on lol. Also taken off the HK and is being put back on the Razor is the craptastic Detrum GY192 gyro. It did work, but being piezoelectric it has its issues.
So once I stripped it down and split the frame in half (you have to in order to remove or install the servos lol) I decided this was a great time to not only install the Tarot Main Shaft block which is one solid piece and provides a wall to keep from chafing wires on the main shaft, but I also decided to install the Tarot V3 aluminum tail block. The stock SE V2 or HK450GT has a very small tail block and a separate block that holds the tail drive gear. The V3 block (which I had in my old Align SE V2, but was the plastic Align version. Still great, but I wanted the bling lol) takes those two pieces and makes them one. Must stronger with this solid aluminum tail and main shaft block.
I had modified my old helicopter where I could lower the battery and use a Pro canopy on it. I have decided to not do this on this helicopter. I'm going to stick with the plastic canopy that came with it. This is the white one, not that craptastic red one they like to send...
So with it stripped down went ahead and installed my Emax ES09MD servos in the cyclic, and I put an Align DS520 tail servo on it along with the GP780 tail gyro. I also installed a black Align Helical main gear, but kept the black HK auto gear so that it was all black lol. So the only white gear is the tail drive gear.
The head is the Align flybar head with solid links and I replaced the tail boom with Align as well just like my old heli. I still need to find my old 450MX Align motor (I think that is the number of the one I have) so that I can get it installed and running. The motor is going to be paired with the Align 35 amp ESC as well.
Blades I'm up in the air with but I think I'm just going to put the white with black stripe fiberglass blades on it. I have proven that you can't toss thing thing around in the air otherwise you will spin the flybar paddles. Video below of what happens when you do that lmao.
I am very excited to get this helicopter back in the air. I thought about firing up a live stream to do all of this, but those long streams just don't do very well lol. I have been working on this helicopter for about 4 hours, but for a complete ground up, touch every bolt rebuild, that's about right. Pair that with having to find parts that I have had stashed for quite a while and yea, it takes some time lol.
I am now just waiting for the wife to get home with some double sided tape that @Geena suggested and uses on her helicopters and I will get all of this stuff mounted. Maiden flight??? Yea, when it warms up lmao. It was like 5ºF this morning and it's not warming up that much. For you metric guys that is negative a metric crap ton. Cold, nuff said lmao.
Here is the video of the flybar paddle issue that I have had with this helicopter for years. I just face the fact that you can't go high rates with this heli unless you want to put locking carbon fiber paddles on it...
