I use vinyl tape to help hold the wings on.
That is quite neat in the white vinyl. I just put it on so will give it a try on top and bottom of the wing.

I might see if I can get some wider vinyl tape for the bigger planes but this might be all right for them also.

Good stuff.

So what is the consensus on props for this bird? The stock is 5x5, but I've heard that 6x4 is better. What prop sizes are better for desired results?

1. Thrust
2. Top Speed
3. Battery life
4. Sound (quieter)

Also, what size collet adapter should I use as an alternative to the rubber band prop saver? Seems like at this high RPM and with the prop being out of the way it's just not necessary to have a prop saver.

Keep the prop saver if you like having problems like maybe the prop falling off when the band gets a bit old etc.

Prop savers do not help with the balancing of the prop on the motor. It is good to keep the vibration down to help keep the magnets in on the motors.

With the prop saver and a balanced prop I got vibration in my camera and with a 3mm collet and a balanced prop the vibration in the camera disappeared.

I'll leave the size of the prop to someone else to comment that knows all about them.

Great flight at lunch today, but it seems a bit nose heavy with my 2200mah battery. It flies under power perfectly, but when gliding it wants to nose dive. I can't move the battery back any more unless I trim the ends of the control rods or move the servos...which seems like a lot of work.

I grabbed some DuBro EZ Connectors for the ends of the push rods at the elevator and rudder connections. I plan to clip off the Z bend like others have suggested, and opt instead for an easier connection that I can adjust without messing with the servo attachment point. I also picked up a 3mm collet-type prop adapter and an APC 6x4E propeller. The rubber band/prop saver deal worked fine today, but I would rather have a firm connection than a flexy rubber band.

Most of these items are nitpicks, but I'll list my gripes thus far:
1. Prop saver is prone to vibration and noise. (Change to 3mm collet-type adapter)
2. Battery compartment has no "hold down" mechanism. (Use strapping tape or velcro belly strap)
3. Z-bend type connections at the control horns are difficult to adjust and remove. (Clip off z-bends and use EZ Connectors)
4. Control surfaces are very stiff and need to be scored or cut to move freely.

To be fair, here are the great things about this plane:
1. Dual purpose: pretty speedy on WOT, glides nicely with power off.
2. Flying time on 2200mah under moderate throttle usage is 20-30 minutes.
3. Prop location makes it simple to land on grass without worry of breaking props or bending shafts.
4. Easy to fly for beginners, still fun for more advanced pilots.
5. Simple assembly takes < 1 hour.

Thank you!

Thanks to everyone who made a suggestion on how to keep my wings attached during flight. I found some packing tape that holds well and peels off well. It comes with its own dispenser and cutting tool for ease of use.

Hmmm, I've read a zillion times that a 2200 mAh battery was needed for proper balance. I just ordered two this morning , and will do a maiden when they get here. Did I get the right thing? What might account for his nose heavy issue?


And thanks for all that other info, TwoHeads.

Well, it's better to have a nose heavy plane than a tail heavy plane, much easier to fly. And under power it flies straight and level, which is also a good thing. I'm just noticing that it's necessary to use some up elevator when gliding, which tends to just slow the plane down. It still flies great, don't get me wrong! The 2200mah batteries are great for the long flight times.

What I'm going to try is moving the battery all the way back towards the servos, as close as possible without having the arms hit the battery pack. This "should" make it a bit more balanced and help with being able to glide. If that fails, I'll be making a battery lead extension from the ESC and moving that all the way back by the propeller.

A few pics of changes tonight: 3mm collet prop adapter with APC 6x4E prop. Relocated ESC to behind servos and cleaned up the wiring.

Hello all, if you buy this, or already have one, you may want to run tape to "permanently" affix the wings, don't rely on the puzzle peices on the inside of the wings to hold them in, they wont. Already had it split into 3 pieces on me..

3 blades rule!

I put a HK HD Wing cam on the canopy (see earlier picures 450 heli). I'm quite happy, though the big clouds cast a lot of shadow. It shows almost no vibration even at WOT, so the cut back 3 blade I use for cruising is balanced ok.

1 - find where it glides well and remember that amount of elevator on the plane
2 - find where it flies well at full throttle and remember that amount of elevator on the plane
3 - go into your mixing and mix some down elevator into full throttle / up elevator into low throttle
4 - verify that at low throttle you have #1 elevator trim and high throttle you have #2 trim, adjust mixing and elevator trim till it is right
5 - fly it to fine tune it

I cut my extra servo wire off and run 2200's as far back as I can without hitting the servo arms. A friend runs his 2200's in the middle. They both fly fine.

I am surprised: I fly mine with the Turnigy 2200mah all the way in the nose.
But it doesn't feel nose heavy whatsoever.

Where do you guys have CG?
