Hahahahaha! Oh wait, your serious. (Sorry, I just had to say it.)

Holes in front and back to force air in and out or mount your ESC on the outside.

You are as bad at overbuilding (and underflying) as I am at overexplaining.

2.3mm collet style prop adapter from eBay because HobbyKing is probably out of stock. There are several posts about this in this thread.

The stock prop adapter is difficult to get off without bending the motor shaft. Use a needle nose pliers on the 2.3mm part of the shaft and seated against the 3mm part of the shaft. Use two flat screwdrivers to pry between the needle nose pliers and the prop adapter at the same time to keep from bending the shaft.

Run the motor as slowly as possible without the adapter afterward and carefully straighten the shaft if you can see that it is bent at all. You will see the bent shaft and which way to bend it just as the motor stops.

The stock motor flies the plane very well with a 6x4 prop. It will go almost straight up. I would say you don't need to buy a new motor till you have tried the stock motor.

The ESC burnt up very quickly -- but that might be an isolated situation.

No other changes were noticed.

EDIT Ya know.. strike that. I thing the Surfer I got from readymade is actually a V1 so the other might be a v2.
I think I ASSumed.

How's yours stack up?

Mine is a porker compared to that. It is a Sky Surfer kit and weighs 623 grams without the battery. I think their RFW is a total fantasy.

47 grams of washers removed (50 grams with the glue).

6 grams of finishing nails in the right wing to balance it.
8 grams - .188 ID CF tube to strengthen the spar.
? grams - 3mm x 344mm CF tube to stiffen the horizontal stab.
? grams - 2 inch wide Scotch 'Tough' clear duct tape (bidirectional fibers) the full length of the bottom of the fuse and back to the canopy on the top.
30 grams ??? - A six inch by about 1.5 inch plywood floor from near the nose to the hole in the bottom under the canopy. It's doubled for two inches near the middle to bring it near the curved floor of the SS. The plywood would be about 17 grams plus Lots of glue to hold it to the floor of the SS. This was done to have a flat surface to velcro the batteries to.

Note the XYH B2835 KV2200 inrunner from Value Hobby that I put in it is advertised at 95 grams for the motor alone and I added about 11 grams of heavy silicone wire to extend the motor wires. Don't know what the Bixler's motor weighs.

Flys great at about 812 grams flying weight with a 2200mah battery. No problem with vertical using the 6x4 prop. It's first flight was about half an hour with only about 2:38 of actual motor use. It thermals quite well! And I fell back to the Command hooks and rubber bands in the end. The Velcro I tried was useless.

Regards,
Gord

2 - Take off at 50% power.
3 - Fly at 33%-50% power but remember that you can't climb steeply so you must keep the nose from pointing up. Stay away from full power.
4 - Don't over control (easier said than done!). Force yourself to use the minimum amount of stick to get something done.
5 - Immediately after take off and adjusting the throttle for flight power, trim ailerons and elevator for level flight. If you cahnge the power, you may have to re-trim.

Cliff
6 - Decrease throw of control surfaces by attaching pushrods in outermost control horn holes.
7 - If already there, move one hole inwards on servo arms.

I just realized I don't quite understand something about your post Skyhopper. At the top you say it weighs more than 650 grams without the battery but at the bottom it says 512. What am I missing?

(Hmmmm....bendy straws. Yeah....that's da ticket! Where's my glue bottle!)

*LOL* Yeaaahh...I'm a dreamer. And Tinkerer. I find solutions where none is needed. Can't help it - it's in m' blood. I can't hardly look at anything without thinking "There's gotta be a better way."

And things hangin' outside.....awww...that's just ugliness, & I'm one who appreciates a clean line. 'Sides, I'm uglier'n a sail possum, & I don't want nothin' hornin' in on my share! That way, everything around me just looks that much prettier.

Anyways...gotta run. I think I know how I can get them farads back in that tiny li'l tomato can.

One question I have is related to the ESC. Even though the FY21 is not that big, it did add some weight (under the wing, right on the CG).

After 20 min flying, the ESC got very hot as the sticky part of the velcro melted.

This is the ESC I'm using:

What is the recommendation? Wire the ESC outside the plane for better cooling?

Another question I have is related to the CG. Beside the battery, I can't put anything in the front canopy because it makes the plane nose heavy. I have to stuff the Rx and ESC on the left of the servos to make my plane level on 60mm CG. My plane is a V2. Am I the only one with this problem? At the moment, it is fine but for instance I couldn't put a Go Pro HD on the canopy, it will have to be on the wing (causing a lot of drag) if I want to keep my plane level...
What size prop are you using?

Oops -- found the bug -- bad formula on my Excel sheet. I was one cell off; my weight posted was WITH a 2200mAh, putting AUW at 707g, or 57g over recommendation.
So....subtracting the 195g of the LiPo....correct ZFW is 512g! Thanks for catching that Gordo! Now it don't sound like such a lead sled!

(Guys...remember, only individual things of more than 3-5 grams each....not 'belly tape' (unless it's very heavy belly tape), small CF pieces used in tail (very light), etc. Will help keep the posts shorter.) Plywood floor was a good inclusion! I've just got a glued-in velcro loop floorstrip - weight negligible so didn't mention that. Like that.

Almost wish I could ask this w/o doing it 'out loud' here....but weren't some people reporting problems with those Plush's? I placed an order for a UBEC just while ago; wanted to add a 25A Red Brick but I'm beginning to think there ain't a <$20 25A ESC for sale on the face of this earth - everybody's backordered!
