@DragonAerotech I agree with the floating planes and water planes they are awesome
@fnaf1987 My friend wanted to know my thoughts on this recent build so I tested it out and gave him a full review of my experiences with this plane. I love floatplanes and seaplanes because they provide a unique challenge both to build and fly and this one was crazy fun! :-D
@DragonAerotech I can't believe I read that howl thing cuz I was randomly reading coments
@DragonAerotech Well the thing is that I fly my planes with a joy stich and have far more control than with a keyboard. And at the moment I figured there would have been a boom in civilian seaplanes since the islands have nothing but water so that would be a good way to get around. Ill be coming out with a few other seaplanes soon. Thank you for the advise.
@TheOwlAce You know me and seaplanes or floatplanes. XD Of course I tested her out to see how this one works out. I was surprised at it's appearance. The real Dornier Do-22 was quite different after all but that wasn't what really startled me it was that it is nearly identical to an idea I had to refurbish old planes as small seaplanes by adding just the sort of gondola and outriggers you did here. XD I was pleasantly surprised at how spritely she lept out of the water at 119-120 mph but once I released the elevator she immediately began to pitch forward. I couldn't stay in cockpit view for long, I don't normally anyway unless I'm gunning for a kill, but if I had I most assuredly would have become sea sick. With the bottom stabilizer having pitch controls of that size in addition to those on the tail the slightest application of upward pitch would cause her nose to shoot up to a 30 degree angle and bleed off quite a lot of speed, which with this aircraft especially, can be quite dangerous as I soon learned.
I began quickly jabbing at the key to flutter the elevators and that helped some and allowed me to gain some speed and altitude. I decided that I wanted to test her in landing and intentionally pitched down; Only to then begin tumbling end over end. On that flight I tried my control surfaces to recover but it was useless. On the second flight I put her through her paces again and this time got a good bit more altitude as I felt I was going to need it and once again pitched downward - it immediately began tumbling again. This time I throttled down and the tumble gradually stopped with a nose down attitude that allowed me to pick up speed and again turn on the engine. After that I landed her in my typical fashion, on a dead stick and she skimmed into the water perfectly. The bouyancy balance is great but I wonder if the lower hull could be reconfigured so you can omit the 600 Lbs of balast in the front? Anyway on my third flight I tested the tumble effect a couple more times but on the last she actually stalled out in a nose up position, backslid and slowly did a perfect (though uncontrolled) hammerhead down to the drink about 1200 feet below. Since the pitch is so powerful another idea is to create elevators that are only used when landing or taking off with some bodyless rotators and structural wings nudged in? AG 8 would be perfect for that since it starts out as active. Although it seems like I've done nothing but criticize this build I actually found this aircraft to be very fun to fly, it maneuvers and behaves like a civil aircraft, it's not built for aerobatics, it's a small civil seaplane - something you don't often see. I also like that she's a little quirky, once you're aware of it, you can avoid it or recover from it. Good fun for the adrenaline junkies! XD I also cannot stress how impressed I was with the bouyancy balance. I know the balast is there to counter the weight of the rear fuselage but I just wanted to suggest that there might be another way to balance her out with a "gondola" redesign. However its not an absolute necessity, she's fun the way she is. Good work on this bird, just add a lil note in the description to avoid sharp in flight forward pitches and if it begins to tumble, shut down the engine and she will recover, allow it to accelerate to 150 mph or higher, throttle up and voila - recovery.
@AKS001 Figure you would like this.
@General360 Where do I get the link from?
@DragonAerotech What do you think?
@Liquidfox Thank you!
@General360 Basically yeah. How do I make a post with a picture in it?
@General360 I was thinking about doing a story series on here about imaginary pilots that fought in the RP war I had. Would also show the different aircraft that they flew too. What do you think?
@General360 Can I ask you something
@General360 Thank you.
