I kind of like the lighter feel of the airplane with the 4400ís in it honestly.

It was a little on the breezy side today and no flap landings are a lot easier to nail in the wind than with flaps, especially full flaps. You can definitely get the wings rocking with full flaps in the wind which results in a less than spectacular landings. Without flaps you can get it to settle right in to a nice 3 point landing and it sticks. If you donít nail the landing with the flaps and in the wind it wants to get airborne again very easily.

I backed up multiple times with the reverse thrust in addition to using it on landing. Pretty cool indeed. I did run into a problem though on my 6th flight, I decided to back it off the runway. It went about 10 ft and the tail sat down. I put it back in forward thrust and I could see the tail was still down. Walked over to it and saw the tailwheel yoke snapped clean off. I guess it was something I did, but after seeing all the backing up in the videos, this is not what I expected. I was flying off grass. I am going to try to repair it by putting a self tapping screw up from the bottom with a little glue on the adjoining surfaces of the yoke. Tailwheels are in stock though so I will order one for good measure. Just a word of caution though for those of you flying off grass that maybe prolonged backing up isnít a good idea....
Just add a screw and nut through it

I added the screw from below, see above. That is another idea though, just putting a bolt through the entire assemble, yoke and arm, then a nut. Would be even stronger.

Oh God yes!!!! She will never come down like that lol. I typically have pretty aggressive landing flaps but Draco doesn't need them...especially with a decent head wind. I come in at half flaps and go full about 5 feet off the ground. With strong headwinds....just stay at half! Deacon's wings are about the lift. Huge amount of ground effect too. If you wanna use a lot of flaps you'll need to land nose high, on tail wheel like Mike Patey and basically stall about 6-8 inches off the ground. That's how the Draco do lol. I'm getting some Dubro 5.5" inflatable bush tires too. Coming in on tail wheel,and she'll bounce a fair amount. Don't have the Pratt and Whitney turbo prop up front. Just a 6s 6000. But...I can't imagine anyone breaking the gear unless the lawn dart it. It ain't Timber gear.

I have gone into the telemetry menu and inhibited warnings about all the RX items but I can't find the rssi specific menu item.


I think this is the relevant post you are referring to:

If it had 348 HOLDS ( H: ) there's pretty much no way it would have made it through the flight Even just a few HOLDS -- which result in a complete loss of control -- would not be good!

FADES ( F: ) on the other hand are a VERY different story The new Spektrum chipset works different than the previous set did, and it's not uncommon to see a few hundred fades on some flights in some places. But fortunately that's not an issue and is nothing to worry about

But again, if you are seeing HOLDS, then you may need to be concerned. And yes, you can add a remote/satellite receiver if you'd like (but it should not be necessary for this model). This is the one that's compatible with the AR637T/AR637TA:

I haven't moved any antenna wires or messed with the stock RX placement. I'm using one of the canned SPM files, just for 'fun'. I think I'm going to go from scratch like I should have done in the first place.

Make sure the light controller isn't sitting right on top of receiver. I have mine pushed back. Anything with electricity is going to have electromagnetic waves around it. Having that on top of reciever can cause issues. I used to have bad holds on my F16 70mm because battery connector was right next to reciever. Got a cable extension, swung batteries 180 degrees and no more holds.

Now, I have had a couple of random holds on Draco but they have been so short i didn't even notice until after landing. We also fly in a field with well known dead zones. Have a City of Phoenix relay tower close by that PD and fire uses. But, with Draco....if you have 10' in altitude you'll have about 8 seconds before you need it lol. She just floats.

Regardless, I did order an Remote reciever. Never can be to sure and $40 is worth insuring $600!

I have a Motion RC AL37 with a 637T and remote and still get the occasional hold. But again, it's so brief and typically when I have a lot of altitude that I never even notice, it's so brief!

Hate how the exhaust looks like cheap 1 dollar toy. Had to fix that. Along with other scale bits coming along.

How did you weather the exhausts like that? Looks really good.

Just curious about the Tech Bond. Which version did you use.

Thanks! Rustoleum gold chrome lightly misted on there to keep the reflection of the chrome plating then flat black inside the exhaust.

So I got a chance to really put my Draco through its paces this weekend. It's an absolute BLAST!!!
I was flying slow landings in the dirt and grass for hours with long 10min flight times on a 6000mah pack. So much fun!

The fun came to an end when doing cross-wind landings and on the pavement, the gear touched down with a little side load. It bucled the gear on one side, cracking the carbon at the lower bend. The prop then struck the ground and broke. No other damage thankfully, just the gear breaking here.

Has anyone else had problems during a slight side load? I was suprised because it handled pretty decent front drop loads in landing with no issues over and over, but side load and boom it snapped. Is there a fix here? or am I looking at a new carbon gear leg piece?
Thanks everyone.

Awesome! Thank you. How did you tape off the airframe so no overspray got on it without removing the paint when you pulled the tape?

Wow that is a surprise the gear failed like that. I feel the same way about my tail gear failing from driving backwards. I know what you mean through about it not liking crosswinds. I had a couple not so graceful landings where it would touch down on one wheel, grab and drop a wing, then flop over to the other side. Once it started that action you were along for the ride. Finally I just started landing at a 45 across the runway and all was good.

I donít know what to tell you about repairing the gear. I donít think I would trust a repair though. I would just replace it and the buckled piece as well. Unfortunately the props are backorder until sometime later this month.

It would be a lot easier to take them off the airframe, to paint.
The exhaust is held by a single screw, inside the battery compartment.

Ah, ok. I thought they were glued on.
