Hobby King Radjet 800 with modification
After reading another thread and talking about the fact the Stryker is no longer available and wanting a good replacement, I let Dahawk talk me into buying one of these with some modifications to hopefully "speed it up" So if its a complete failure blame Dahawk. LOL just kidding Hawk...
So here goes:
First of all, I thought I had purchased the Kit version of this plane but I must of mistakenly bought the PNP, so if you plan to do mods to this plane I recommend the kit version so you don't have to carve it up like I had to.
My plan is to replace the ESC, motor, prop and a 3 axis flight stabalizer from hobby king with the following:
Motor: Hobby king 2200KV motor
ESC: Phoenix Edge Lite 50 Amp ESC (yes expensive but programmable and easy to convert to 4s or bigger if you choose)
Battery: 2100-2200 MAH battery
(again expensive but they are what I have)
Gyro: 3-axis stabilizer http://hobbyking.com/hobbyking/store..._Receiver.html
So first came the unboxing and I was pleasantly surprised at how well it was packed. I was also surprised that it to came with a manual (turns out is has a lot of pictures but lacked info)
Next I began the soldering process. What a pain, it always is but has to be done.
Then I began to replace the motor and ESC. To do this I had to cut two sections of the fuselage. One was right above the motor to access the motor mount and the second was right above the ESC. I kept the original motor mount and the motor lined up perfectly for the motor replacement . Glued motor back in and added the ESC.
Then the difficult part began, getting the stabilizer setup was a royal, time consuming pain in the azz, and I had to carve out some foam to get the stabilizer into the fuselage. Now I know you would think just switch the gyro switch to delta and activate the stabilizer switch to aux 1 and away you go. Yea not so much. I am not sure of the exact setup by the manual (I did not get one with the stabilizer) but after a lot of trial and error, this is what I did to get it all working:
1) set up radio for elevons and ensure ailerons are functioning properly
2) on the flaps setup ensure norm/Flap is 100% and all others is 0%
3) on the stabilizer keep all switches in the off position except for the last one closer to the pins is in the ON or up position
Finally I finished putting on the wings and glued hatches up.
Last but not least balancing the plane now the CG was never officially posted and their a lot of opinions are where it should be so I SWAGed it. I balanced mine just in front of the throw holes and after adding 28oz of weight in the tail I think I have it.
So there you have it the Radjet 800. I am hoping to maiden this weekend but weather here has been unpredictable her in the Ole Wyo so we shall see Hope to have a video to show
Edit: As mentioned in a lower post by Wildflyer, when setting up the 3-axis stabilizer be sure to leave the transmitter setting for wingtype as normal and on the stabilizer turn delta ON
Here is my Watt settings for this setup
Happy flying may your crashes be limited and if they are not limited let them be cool.
