Going well on 7s, but 6s with larger prop is the sweet spot, being lighter with the same thrust.
All prototypes are flying well in the lingering summer heat.
New batteries and more powerful designs coming in time for cool fall air.
Working to get 8s perfected.
Here is prop failure and motor shed after a couple short bursts...
8s test with blade failure (1 min 49 sec)

Here is a twin 1500w potential system.
I aim to be a leader in power to weight, with a full 3000w+ static @ only 22.5 ounces!
Only 7 flights so far with 1500w total max.
Update later with more pics, tests, and video.
Update.. needed caacitors to run well on 6s..
Stuffed all I could inside the nacell.

About as high power to weight I have seen in person..
Video is over 1500 watts static @24.5v and 13 oz with 870 mah pack. (Yes, tested to over 60a)
15-25mph cross wind.
Launch into loop at only 40% throttle...
5 minute flight was 700mah/870!
Fastest passes at 3:00.
1.2 second delay on throttle, now tuned to .5.
(Now faster)
Everthing runs reasonably cool..

Here is another 27.5" racer with over 1000w!

This one uses the mighty Tmotor F80 2500 kv and matching 45a esc.
Gemfan 5x4.5" carbon prop.
TP 860 mah 70c 6s.. (Two 11.1)
338 grams or 11.9 oz rtf.

UPDATE.. Make it 10.9 oz with Tatu 650

LIGHTEST 1000w+ plane?

These are the latest in an evolution of homemade micro pylon/hotliners spanning 24-27.5", and weighing 165-249 grams rtf.
They are foam core with balsa, using glass and carbon on the fastest version.

The goal is to achieve better than 1600w/lb by a good margin, as this appears to be the upper limit for high$$ hotliners.. all this UNDER the FAA regs or under 250 grams!
I am currently at 800w/249g with a 1000w++ setup coming..

"Quarter Pounder Racer"
All wood, foam core 22" wing.
120 grams auw with 300 mah 4s.

Could This Be The Lightest 100mph

More details and vids coming..

Edit.. Too small and light. Not enough power for 100 mph.
moving on. See above....

There is always the question of which colors are more visible..
In my case, I decided to add the entire neon palette!

This is the fourth 5s modified Baby Shark, with the last lacking in visibility.

Light weight brings over 100 mph on less than 10 amps, and up to 5 minutes flight from only 300 mah out of a $9, 370 pack!
I have spent thousands on thrills that did not equal the fun and attention this little plane brings.
This third prototype took 12 hours to cut, sand, and paint.
It uses a no pin Lemon rx that weighs 1.4g!
Everthing is direct soldered to the rx.
The most expensive component is the $33 esc, with everything
totaling about $100.
The Talon 25 esc is lightened to 9.8g.
I bought a new GREX airbrush so expect more artsy craft like this.
Look close and you can see the clear yellow top window with gear under..

Here is a slimmed down and lightened Nano planes Babyshark.. this time on a 370mah 5s!!
R415X rx with 3g digital servos.
HK 2211, 2300 kv 17g motor with Talon 25 esc.
Nanotech 370mah, 2 and 3s in series.
4x4" GWS

24" wing. 610mm.
5.5 oz , 156g with lipo.
5 minutes mixed throttle flight on only 370mah packs!

**Update.. "7" has retired after over 100 flights, still in flying condition.
Replaced with new stiffer and lighter frame with new packs!!

** This is the discontinued Nanoplanes kit, with free plans found here.. http://www.nanoplanes.net/bshark.html
Notice the video on the website.. this 5s is much lighter and as fast.
Very dynamic!!

I am currently offering my 30 years of r/c experience to help build and fly any project one may need help with.
I can answer questions related to flight, and perhaps, provide a little inspiration to dream up something special.
It is part of my master plan to continue to build my resume, and further sharpen my crafting and flight skills.

Everyone is welcome to message me for questions or ideas related to fixed wing craft.

Happy flying! Mike

Ok here is another $20 wonder kit.. yes for less than $100 for everything including rx, you can have a mini-pylon racer that has moves and a power to weight ratio that rivals much more expensive ships.

Mine, at a mere 5.5 oz auw with 4s battery, gets up to 5 minutes flight on only 360 mah of capacity! It is hard to comprehend how something goes so fast, for so long, for so little $!

This one has had a couple bad crashes, but repairs easily using a little c/a, sanding and paint.

Gear: Spektrum ar6310, HK 2.9g digital servos, HK 17g 2300kv motor, Plush 10a esc. Krylon white primer, matte black, and orange (curb) paint.
Easy stencil for checkers.

Modifications: 6mm depron horizontal stab for weight savings and balance.
2 servos on aileron set up for flaperon.
Front and rear spar deleted for weight savings, micro carbon added to tips to prevent breakage.
Magnet hatch.
Micro hinges on surfaces, no tape.
Lightest gear available chosen.
360 mah 4s homemade battery.

Another cool Nanoplanes.net kit.. 24", 13 oz. with 4s battery.
Power and tiny size makes it crazy fast.

These are some of the best kits from the USA and I am proud to represent them!

These are proving to be faster than my wings using the same power system and coming in at the same weight.

24" of dynamic 3mm foam pylon racer..

5.5 oz with 360mah FOUR cell!
HK 2300kv 17g.motor with 4x4" GWS drawing less than 10a. =3 min,wot.
3g digital servos with AR6310 set to 2048 resolution, and 11ms. speed on DX9.

This one has an internal digital servo for each aileron utilizing flaperons for killer turns.

Fast, precise, and FUN!

Here is # 9! These are all prototype 22" KF wings that are fully sanded 4 layer 6mm depron and 5mm Midwest Cellfoam. (All trailing edges are 1mm, etc.)
There seems to be an evolution of this series as each prototype seems to fly a little better based on a continual change of sweep and cord.

This one uses 1/2" more cord and lenth, 1/4" more elevon, 1" more nose width at the wing LE, and more dihedral.
Weight is up .4oz to 5.5 oz (156g.) with 450mah 3s, but wing loading is the same.

The term 3d wing has been mentioned alot becuase of the wing's ability to hang on post-stall in upright and inverted harrier..under control..without rudder or vectored thrust. I measured a peak of 16 oz thrust on 5.7 oz flying weight
Oh.. and it can go 70mph

These aircraft are getting alot of attention wherever I fly!
Everyone so far is a new prototype with design changes..
Green is #6 22", #7 (pink) is the new 24".
The latest being a sweep change, fins, and a wing increase to 24".
Every change so far seems to net some kind of positive result, although I have lost some inverted harrier control, while gaining upright harrier.
They are fast like a pop wing, but can stall into maneuvers that people consider 3D, and fly super-slow.
Huge elevons, huge thrust, and light weight add up to a very compelling package that I fly in the tightest of space.

I am also testing inexpensive gear including the new $8, 1.9g. Lemon RX recievers for JST plugs used on the $6 HK 3g. digital servos.

I will post a build and flight videos..

Now using 6mm depron, larger moments, and more focused airfoil for superior results.
This little home-foam wing is making other planes gather dust, including the very Inverza the motor/esc came from.
So simple, yet sooo dynamic.
Come fly with me!
