Also, any body know or can place a picture of home made engine cowling that I might make? Well appreciative if you could. Thanks in advance.
Anybody else scratch building tonight?

I don't see anything usable for a specific cowling for the BB. But if you have a 3d printer you might be able to fairly easily modify this to fit. It's a swappable series so the size might be pretty close with minor mods on the baron.

Do they come with specs on the box when you buy the ESC brushless motor? I need 2000-2400 kv and that can guarantee and engine thrust of 1000 gram of trust or 9.81 N. Assuming final weight of my airplane weighs in 2.2 ibs or 1 kg. I meant this Kendin Yap’s model revised at the cockpit area. This airplane weighs in at 530 gram now. Just about 1 kg after everything is on it. 1:1 weight to thrust and take off ratio. I am using a propeller that has a 6 x 3 dimensions. So 6 inch diameter and a ”3” punch or pitch factor. I also saw that Kendin Yap makes his own transmitter using Arduino programming. But I’ll be using a Spektrum 6 channel model radio or RC. Final specs then, 1000 mah LIPO batteries, ESC 30 A brushless electric with brushless Motor (2000-2400 kv), 2 front 40 mm foam wheels and 2 mm or 1.5 pushrods under the wing area. 5.5 cm to the Croot making the center of gravity just at the front area of the wing. And a trailing end. And hopefully this flies. Well I’m not new to math, I have college math calculus, but if this flies, 1-3 batting average as Captain Mouser. One info it will have 4 9 gr Micro servo. Two at each side of the wing area, one on the elevator, one at the rudder, and the channel belonging to the thruster will have it’s own slot for the receiver connected to the ESC 30 A electric. Making it complete.

Some motors come with the specifications In the box. Alot of times you can look it up on the internet before you buy it. There is alot of motors to choose from out there. But your 6x3 propeller will greatly lower your choices. A 2208 1800kv might get you there with that propeller size depending on the battery you use. But you will really have to push that motor hard all the time. You might be better off with a bigger motor with lower kv and bigger propeller with a plane of that weight. I fly the flite test mustang with a 2826 2200kv motor and 7x4 propeller with a 3s lipo battery. But that comes in around 750grams total weight.

you can blow it up in adobe, then tape together all the pages at the cut lines, or you can go to places like staples, who can blow it up on one piece of paper.

Acrobat allows you to print at almost any size by scaling up to the desired amount and the printing onto multiple pieces of paper that you assemble and overlay the foam board or whatever material you are using.

Yup, I used that for my 200% A-10👍

Is there an A-10 scaled down for Mighty Mini Power Pods tho?

I don't think so...I was getting ready to start on one, but never did😂 (When I made mine, I just scaled it down in adobe)

I got the correct specs now for my airplane. 253.87 grams. 8.955 oz = 253.87 grams. 1 0z. = 28.34952 grams. Metric unit conversion. 8.955 oz to 16 oz. Which is equal to ibs. I know I missed the calculations to just checking for the final specs for the AI google tech guys to give me the confirmation on the specs on weight and other flight numbers to go on. Battery and buying it. 1 kg =2.205 lb. Thank you if any of you caught it. I got to make it as Perfect so as not to waste my money or time making it.
Tape it in vinyl Tape. Yellow and blue color. And keep it under 1 ibs on the bare weight of the airplane. Make it nicer looking model. AI is pretty cool, they gave me the final engine and ESC and battery to buy for this Kendin Yap’s airplane and RC Race Wing I made for free. I think they’re cool. I think also the math guys are psychotic. They don’t miss a thing. But cool.
I went to UH for college many years ago. I’ve got nothing to do but the interest i was into at 17. I am actually a business major but due to the math guys in school i turned into a computer programmer over the years and know Java programming.

That will give you alot more options on motors. I would use a motor in the 2200 range (2205,2207) just in case your weight increases with battery and tape by the time your done. I would go with 2205 size with your 6x3 propeller. Assuming your using a 3s lipo battery and minimum 30amp esc.

ok so i did this for a couple of my builds, if you have a projector or an overhead projector. you can transfer the image to th wall using you phone or pc, it is kind of tricky you are going to use the wings to get the correct wingspan. if you are going to do 73 wingspan you measure the wing until you get the right wingspan. you do this by backing up the projector away from the wall. are are also going to make a line in the middle of your score cuts and make a new score cut because the old one expanded when you exploded the image. u are also going to use the image printed on the image to align the wing making sure it measures the same all the way through. like it might measure 1 1/2 on one side and on the other it might be 1" you got to make sure all the squares on the printed ruler are the same size. once align do not move the projector. use the same distance to trace ur plane. if the wing needs two pieces of foamboard hot glue them and add packing tape. warning tracing the wing on the wall i8s like doing yoga every bone pops nerves scream. well, this is only a suggestion. Remember Its all about having fun. I got to see if my plane garden is sprouting i have planted few over the years.

I made this LEGO tool to make some rivets and rivet lines. Not perfect but not too bad.

Mr Man, you might get happy that I'm actually going to build an RC SR-71, and it SHOULD be succesful this time
