This is my latest project I built over the weekend from a kit I had bought from FMK MODELS of Bulgaria. A 20cm span biplane that will weigh a tad less than 120 grams dry. Tossing it in the air unpowered already shows me it will be a quick lil plane that I will maiden next week weather permitting. The smallest RC plane I have ever built for my COX TEEDEE 010 stable.

About four ounces all up.

Built in a weekend? You must have been busy. Is the vertical stab ply? Single channel rudder only?

Neat little model - Bob

Thanks Bob. This a a simple kit made of not too many parts. All parts are balsa including the stab. So far  2 channels rudder and elevator but may add a throttle for the PET control of the late Roger Freiheit..

Still trying to improvise on the control horns though..Maybe I will heat and bend a small servo arm and fix it on the elevator and rudder..

I use a balloon tank that holds 1/3 oz fuel that must suffice for a 10 minutes flight with the 010

Looks tight Andras to add the battery and receiver up front with that balloon. Micro/nano servos?

Looking forward to your flight report. I still don't see how you guys control those little pocket rockets. Eye, hand, brain coordination a must.

Bob

The 400mAh battery just fits snugly in the nose.
Buzzbipe RC 010 20190919

The balloon tank is oblong rather than bulb-like so it layys over the battery and the bottom wing.
The receiver sits behind the bottom wing.
Buzzbipe RC 010 20190920

These these are nanoservos.

That is a neat build and at 4oz is very light. I built the Miss Tally some years ago and seeing this brought back a reminder of how me and fast little models don't get on with each other,

The reason though that I am resurrecting that build is that on models like this a plywood control horn works very well.

Buzzbipe RC 010 Miss_t10

The full build is her along with my pathetic realisation that it was too fast for me.

https://www.coxengineforum.com/t6373-miss-tally?highlight=Miss+Tally

I should have done a postscript. Through this I learned how to do mixing on the transmitter and could then make turns without the roller coaster effect but one day, it started off calm but being in a sheltered area I hadn't realised the wind had appeared. I went up over the tree line and suffered a blow away. I saw it lift high and fast, killed the motor and lost sight of it. Never found it!

Sorry to intrude on your build which is excellent (mine weighed 5oz and I used much, much lighter battery and receiver)

Thanks Ian a good reminder for me that this is the first biplane I will have ever flown..I am really looking forward to experimenting it. I am curious to see how the plane balances in flight with those short wings and reacts to the rudder. I also saw one of my micro planes with a 010 in its nose disappear due to a radio failure..a heartbreaking memory indeed.

250 mah batteries out of England are still over kill but way better than 400mah weight wise.
I use 80 to 150 mah for TD .010 projects. My last project gets 5 flights with 80 mah cells.
The cells peak out at 93 mah.

400mah will give you over 18 flights per charge way over kill.

Thanks Brad especially for the link on the batteries..the few I have seem to have died by now and only 1 stayed alive for this project..I will buy a few from the source you gave me.

LiFe batteries are the very best if your system can handle 6.6v
You can charge them up leave them for a month and they will
have retained their charge 98% very very low discharge when
not in use. Here are some weights!

One has a on / off switch high performance for small RC cars.
If you weight your switch and your 400mah battery is it 17g? Surprised

I use two cell lipo batteries with a lipo regulator.

Buzzbipe RC 010 Lipo_r10

The total set up including switch is 22g

Buzzbipe RC 010 Radian10

but I usually take the regulator out of the plastic case and neat shrink wrap it that saves another 1g. I do that though to save space and not weight.

Choice of batteries depends on your charger.

This is my go to switch for .020. For sport flying ok with the TD .010 / for speed I use a lower weight switch.
The wire gauge is the least all up weight is 3.7g
Buzzbipe RC 010 S-l16028

https://www.ebay.com/itm/RC-Switch-ESC-Control-Switch-for-FJ-HiTec-JR-1570-Plug-N-Play-Design-MPI/372652753658?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D1%26asc%3D20131231084308%26meid%3De065c6d57b754de6b063e8c97e2271a7%26pid%3D100010%26rk%3D7%26rkt%3D12%26sd%3D173595947515%26itm%3D372652753658%26pmt%3D0%26noa%3D1%26pg%3D2047675&_trksid=p2047675.c100010.m2109

Note the next step uses 3 wire system with a separate charging lead at 4.2g:
Buzzbipe RC 010 Imag6411

This was the system weight of my last TD .010 speed project less 1.3g switch and 80 mah lipo 5.1g
Makes the entire 2ch flight system 27.2g. The plane ended up at 2.1oz RTF.
Buzzbipe RC 010 Imag2811

Full range AR410 in shrink film at 4.4g / pin orientation is perfect.

beautiful model Andras !! ... I hope to see it in flight very soon !!
By the way, I have this kit, a few years ago I bought in a store here, always with the intention of doing it at radio control, modifying the wing (to place ailerons), also rudder and depth, also clear motor control. The idea was for Cox .010 / .020 ... what do you think?

Thanks Mauricio..

I am waiting for the winds and rain to subside by the weekend for the maiden flight..


That model kit is beautiful. But I am not sure if a stick and tissue fuselage is strong enough to absorb vibrations generated by an internal combustion engine for a long time..so for a 010 or 020 TeeDee my preference would be a full balsa sheeted fuselage with plywood formers.

The kit is certainly excellent for electric motor .

MPI Maxx with charge cable shown in a previous pic 4.2g product number 1470 that's 5.34g less.
Plus more room in the fuselage if need be.

Post  MiniatureAircraftFactory on Sat Oct 12, 2019 4:50 pm

I'm not sure I still own a switch..., I plug in the power to the receiver to turn on every time on every model, when I did I used the ones from 27mhz hitec ranger sets ( in the 1990s) as they were a bit smaller and lighter than the futaba at the time.

For the receiver power on this model and the other 010 ones I use a single cell 50mah or 100mah lipo and a tiny voltage booster that turns 1s lipo to 5v it was about 2 dollars from china, I used to use 50mag nicads but they died so changed to lipos.

My latest Buzz-Bipe i am fitting 2 of the 1.5g linear servos and a 0.8g receiver but it is to be on electric 5g brushless motor not a cox for power for a change, radio is so light now!

I have been silent on the maiden flight of the Buzzbipe and the reason is I so far have not been able to make this bird fly consistently.
First it was tail heavy and I moved the receiver right smack into the nose and now the CG is at the main spar with the nose tilting a bit down as the instructions say.

The plane still flies only a few meters after I hand launch it then goes into a horizonral spiral then stalls and runs nose down into - luckily forgiving - deep weed.

I checked if the wing has been torsioned when the oracover shrunk under heat but cannot see anything irregular.

One of the wings has a bit more dihedral than the other so my suspicion is on it..anyone could solve the puzzle?

Truth is I have been more often unsuccessful with short winged planes than with regular winged planes. (My Lil Stick with its short wing is another less successful 010 story...too bad I can now use my TeeDee 010 only in the Roaring 20 as before, but that plane got a TD020 in its nose now and even though the 010 drove it well, its right powerplant is the 020 that pulls it wonderfully...so I still miss a good 010 size plane from my hangar)

I think that you will probably need to offset the engine - usually a tad up and to the right.
