When I first built this plane I was so excited because I love flitetest and I like park jets. I was stoked to fly and build a flitetest park jet. As per per all the other flitetest planes it when together perfectly and looks awesome.
but then I started to try to get the cg where it was marked. hmmmm did I do something wrong? No but I did have to shove the 1300 mah 3cell way back and up on the shelf in the rear of the fuse. I figured ok well that's not so bad. but I started thinking, I cant fly a bigger battery. I'm stuck using the 1300 which is fine I can get 7.5 minutes on a 1300 mah battery and my 2212-10 1400 kv rctimer motor on an 8x4 prop. but I only have 2 of those so now I'm limited on how many flights I can do.
So I went to do the maiden the first time I just had it nose heavy to see how it would fly. as soon as I tossed it I knew, I was super nose heavy. now I was kind of bummed. I had to fly with constant up elevator just to fly level. which made it fly slow and really unstable, making it stall in turns and falling out of the sky if you let off the throttle, It just would not glide. it also had a nose heavy feel on the throttle( prop above the wing)
so with my park jet knowledge I set out to fix the issues.
first to fix the cg problem and make it so I can put the battery more in the middle of the fuse so I can run bigger batteries if I wanted. so My plan of attack was to get more weight to the rear.
1. I added 1" to the rear of plane pushing the rudders elevons and the trailing edge of the main wing back.( this added a little more wing area as well).
2. I moved the motor and prop back 2". basically as close to the rudders as possible.
this also made me extend the turtle deck on the fuse.
3. I moved the motor to inline with the wing, and changed the motor mount to the regular flitetest fire wall.
4. I moved the servos back 3" shortening the control rods and moving more weight back
5. I moved the leading edge of the wing forward 1". this added more wing area with out changing the overall look and I also changed the wing tips slightly to add a bit more wing area.
the results?
WOW. this things fly's just amazing. no up trim for level flight, glides for days, doesn't go nose up in the turns resulting in a stall. it flies slow with lots of control. and no its fast with the same motor and battery. speaking of battery its now towards the front of the fuse which means I can now fly with a 1300 mah 1800 mah or a 2200 mah battery.
the cg is exactly where it was marked on the original plans. I actually increased the throws and reduced the expo.
let me explain why I could do that. on the original plane everything was stuffed in a length of about 12". Now the weight is spread out over 18 ". This slows do the movement of the plane making less twitchy and transition slower making it fly much smoother with much more control.
This is on just a 1400 kv motor and 8x4 prop. I cant wait to get my 2200 kv park jet motor on a 6x4 prop on here and an 1800 mah battery. This plane will be awesome
I hope Josh reads this and tries my ides and makes a v2 FT22. I think he would agree this is a very nice flying plane.
here you can see the extended under plate and the servos moved back
servos moved back compared to the original
this shows the extra length and the extended turtle deck and motor mount change and the new motor position and the slight changes made to the wing to add area.
here you can see how much farter forward the batter sits now
just a nice shot of the completed plane
I'll be posting videos of the before and after flying on my youtube once they get edited
if this helped or you liked it let me know I thought about making this an article but not sure. let me know what you think.
