Freewing Old Crow

And I just ordered a 3rd twin pack of the batteries. Super excited about this plane

[Grossman56]

Great to hear RM, may you have many long enjoyable flights. The 4500 idea is a great one, I just have dead weight but you have a bigger 'tank' good choice!

Yeah, I need to get a little longer strap though, the one in the plane is barely catching.

[Jorgcama]

Hi again RM, Sorry to bother you. May you please share a pic or measurement of your CG with the 4,500 pack?
any advice on mix programming for take off/landing?
Stay well

[rifleman_btx]

Mine is fingertip cg measured and it is right where the front side of the light blister meets the wing, exactly where it shows in the manual. And as far as mixing, I never used any so I wouldnt know what others would have used. But I dont recall any ballooning with the flaps full down on landing so I wasn't worried about it.

[Jorgcama]

Roger that sir! I have ordered the connector adapters for the 4,500 pack you suggested and ordering the packs tonight. Anxious to see her assembled and up and running👍🏼

[rifleman_btx]

Absolutely, you will love it. Also get a longer battery strap

[Jorgcama]

Will do, used to work as Supply Chain manager at Velcro USA and still have some leftover sample straps, maybe have the one I need😜

[rifleman_btx]

I have some flight video I will up load this evening

[Jorgcama]

I have some flight video I will up load this evening

I was going to suggest that. Thank you RM
my packs and adaptors are on its way.
Thanks again for your advice. Stay well!

Here she is in all her glory

[Jorgcama]

Awesome , steady, very stable flying looks like you are using a stabilizer?
RM, thanks for sharing. So, by the voice alerts I assume you are flying with a Spectrum TX/RX?

[rifleman_btx]

Nope I use frsky. Horus x10

Here she is in all her glory

Nice landing!

And I have to ask... is that your... nose?

[BluesDragon]

Hat brim... only Trump's nose could be that orange...

[rifleman_btx]

Brim of my Astros hat. Lmao

You guys have provided a lot of information in this thread. Thanks for the words of wisdom. I have had my Old Crow for a couple of years now and had nothing but issues. Mostly with the landing gear. I think I finally have it figured out though. The last couple of flights have gone flawlessly. If you refer to the diagram earlier in this thread my struts were coming loose at the D1 and D2 screws causing the struts to pivot forward when they had weight on them. That caused them to hang up on the walls of the wheel wells and not retract all the way. Loctite seems to have done the trick.

The other major issue I had was with the CG. Ended up needing 12.5 ounces of lead in the nose to get it to balance. Used automotive wheel weights from Harbor Freight. Now with the extra weight the performance is lacking with the 4 blade prop. Have not flown the 2 blade, which I understand will help tremendously. But I don't like the way it looks. Thinking of upgrading the motor, but need suggestions.

Currently have an Admiral 4S, 4000mAh battery installed. Not much room for anything bigger than that. I see that you have a 4500 installed. They must be smaller than the Admirals I use.

Here it is with the rest of my hangar....

I had a lot of problems with ground authority on takeoff and landing. It was a bear to take off without it all of a sudden taking a 90 degree turn, usually left. I tried everything from slowly throttling up and full up elevator but it didn't help much. This plane is very sensitive to cross winds especially taking off. I adjusted the landing gear to give her a slight toe in and that made all the difference on ground handling. Taking off is much easier.

I set my dual rate rudder throws to max on both high and low rate with about 10% expo it isn't so sensitive. Makes ground handling more responsive for me.

[Jet Fixer]

Here's the exploded view from the manual

The ones that gave me the most trouble were B1, B2 and R. B1 and B2, you have to remove the retract to get at, but worth it for piece of mind.
D1 and D2 are the ones that actually hold the gear to the retract so pay attention to those as well.

D1 and D2 are my issues. Also added a washer between the strut and servo to take up some of the slop. Loctite is your friend here. My strut would flex forward when there was weight on it causing the wheel to hang up on the well and not retract all the way.

[Jet Fixer]

I've heard that before somewhere. But yeah I was thinking this thing swinging a monster 16x10 prop might be alittle problem when getting the power up for takeoff.

Hold full up elevator to keep the tail wheel planted and ease into the throttle until you get some speed. You will also need a pretty good touch of right rudder until she gets rolling good. Then start letting up on the elevator before the nose jumps into the air. The tail will come up and she will float in to the air.
