Default Kange F3D

I'm looking for a fast plan that I can get in the air in a short time. I have a 32fx around somewhere in my shop. Does anyone here have experience with the F3D? I have a Patriot in the building Q. But I'm a slooowww builder.

Airgar has one with a ST-45 (?) in it I think--- Flew awesome

pretty compact fuse area though... I would use HS-55's and a 1 cell RX batt to save room-

I just put mine together last month. I used the 32SX (with an Ultrathrust performance pipe) for power because it fits the pre-drilled motor mount holes exactly. I tried an 8x8 apc for the first few flights, but it goes alot faster with a 9x6 apc. It was nose-heavy at the CG called for in the plans, so I have been moving the battery aft little-by-little and it handles and lands alot easier now.

I had to bend out the landing gear a little to clear the Ultrathrust muffler, so now the prop-to-ground clearance is reduced and I end up chewing off the prop tips during landings. I suppose if I dead-stick it on landings I would save the props!

As for performance, it is rock-steady, fast and a pleasure to fly. I'm already getting bored with the 32SX however, but I do have a Nelson Q500 just waiting for a chance at the plane! It will require reworking and reinforcing the firewall, the fuse seams and the wing seams but hopefully it should be a decent poor-mans Q40 trainer when I'm done.

So is this thing a real F3D plane, or is it just called an F3D? A real F3D plane will take a RE motor with enclosed pipe.

MP,

Your 32 will fly it fine, however, don't expect it to be a rocketship. As Razor noted, I have a ST 45 in mine, and it hauls it around quite nicely. A quickie motor would really make it skoot.

Landing these is a crapshoot for the most part, as the gear is weak and it tends to bounce. I usually fly it more when the winds kick up, as it helps it bleed off speed, so you can land it without re-sizing your prop.

BTW, the maiden for this was the most uneventful of all the maidens I've ever had over the years, in that it took off and only needed 1 click on the ailerons to trim it.

A great kick around flyer.

It's not a true F3D plane. A bit too small, not tweeked out enough for speed. Just made to kinda look like one.

Careful on engine selection. It likes to go fast, but is not truely designed to go THAT fast. Be gentle in the turns.

Id say fly it with the OS32 to start with........ Its fairly quick with the correct prop selection and either Jett-stream or ultrathrust installed. As Darwin noted, the front end is designed for a 32 anyway.

A couple of people flying these with Jett BSE 30 engines are using APC 8.5x7 and 8.5x7.25 pylon props, and getting good performance. Should be similar with the OS32 using either muffler.

Thanks Guys-

How would this plane compare in speed to a Q500 wiht a 46 FX. I'm looking to use what I have on hand. This way I can save my pennies for the engine on my next project. I'll be starting on my first Patriot next week. But in the mean time I want something fast.

Put that 46 FX on the F3D......

Or, you could buy the "cheap" ($89) Sonic at Hobby People and strap it on that. Just beware of the covering....it's crap, but they fly great with the 45/46's!!

Hey... That Sonic looks pretty good.


And... a question. Would the F3D hold together with an OS 46 on it?

I'm really thinkin' on that Sonic though.

MB,

The Sonic flies great with standard 45/46's. It's the cheap covering I have a problem with. There are a few of us who have all agreed to buy (and have) the Sonics, and equip them all with the same motor (GMS 47) for some summer fun. (we have 5 in the air right now)

Pics below....F3D too

Sorry, I don't have a pic of my F3D. Also, my Sonic was not yet completed when the pic was taken (yellow/beige one), the other is my Son-N-Laws.

There are more, I just don't have pics of them..... All re-covered....

For over all performance, and some pretty good speed....... yeah........stick with the Q-500 planes. The Sonic is a 'scat cat' clone....... flys great. The Lanier Predator is only a few $$ more and is a formidable racing plane (well built, fiberglass in the right places).

Any Q-500 design with just about any 40-46 on the front will keep you happy

The Thunder Tiger .40 pro engines we use for sport racing haul the quickies quite well...definately not slow.

Remind me in a few weeks and I'll let you know. I have shoe horned the radically ported Jett F.I.R.E. .50 from my first Clipped D'Dust into one some time ago..... And I think I can clear my slate enough to finish a few other neccessary mods for this engine within the next month or so.

I am pretty confident that what I have in mind will hold together, and if it does I am positive that it will be 175-190 mph range once I get it dialed in.

This airframe has been just lying around my place mostly finished for a few years now[X(]... The thing is, that I have simply lost interest in sport flying the pylon planform airframes ever since I was exposed to the experience of flying the clipped wing D'Dust.

But I am still curious about exactly how fast it will go, (and whether it will stay in one piece or not) so I have kept it all this time.
I will toss it to the airplane gods fairly soon.

Best Regards, Chuck Roundy

I live and fly in Sacramento (Mather Aerospace modelers is my home club). I used to go to alot of fly-ins all around northern and central Cal. back when I was gainfully employed [sm=sunsmiley.gif]; But I got a self destructive urge to work full time for a few years being an ambassador to the sport recruiting new flyers, and doing my level best to help my hardcore local brethren to get what they need and work through their technical problems.

It seems kind of ironic to me that my decision to do a tour of duty helping the most people I possibly can in my sport, is exactly what keeps me from being able to afford the money or time it takes to travel much and get the chance to fly with anywhere near as many poeple as I used to [sm=rolleyes.gif].

Anyway, you can find me 8.5 hours every day at "RC Country Hobby shop here in Sac., except for Sundays when I'm at the Mather club field like clockwork!

Best Regards, Chuck Roundy

What kind of servos does this plane require? Does it need something like HS81 or HS85 or will a regular 425BB work?
