It's amazing how far you can get on $170. Early adopters paid $750 for a Makerbot Cupcake in 2009.
You'd never guess the greasyality worked as well as it did from assembling it.


Out popped a pinion gear with very little fussing after the bed leveling. A part like this was impossible for a lion to make with paw tools, even if it's as fragile as paper in the lamination direction. It might be able to print smaller gears. The mane limitation is the size of magnets used for encoding position & the need for the magnets to clear the motor diameter.

Ive added a direct main drive motor to my MasterCP with cc3d FC. Its had the cc3d for several years to date and the dmd brought new life to it. Its been flying nice on 2s and better on 3s. I will be replacing the two blades setup to my 4f200 three blades setup using MCP rotors. Much more quieter without the gears. Also, I need to shorten the power cable.

This is another item of lockdown distraction. Good brain exercise.

One way of controlling an indoor model is to use differential thrust and no control surfaces. This is most often done using brushed motors. Purpose built controllers for this form of control are relatively rare but there is an easier way.

Rifle around in your junk box for a "retired" quad with brushed motors. Mount the control board flat on the aircraft pointing forward. Then take the left hand motors and mount them pointing forward a little way out on the left wing but as close together as possible. Ditto for the left hand side motors.

Magically every thing except roll control will cancel out it seems.

If you use one motor from each side then you will get throttle up when you pitch down and vice versa when you pitch up. Sort of a rudimentary height hold.

As you see below the idea works with a retired Hubsan X4 controller.

You can see and hear the effect of corrections on the pitch axis where the planks are very sensitive. If you use a "Tiny Whoop" class brushed motor flight controller, running say Betaflight or iNav, you can tune the control gains easily while using only two motors.

Not too hard really .

Great Jet easy to fly and easy to land. It has one flaw, the canopy will warp in the sun. I have sent three messages to FMS tech support with no response. I also sent pictures as requested. The canopy warped does not affect it flying but FMS should respond and make good on a bad part.

◄► Nils is a Scandinavian given name, chiefly Norwegian ..

In the linguistic context, "Nils" recall to mind (النول or النوال) , and (المنال) .. verb (نَوَّلَ : أَعْطَى) is to give something willingly, as a (gift العطية) .. (donate graciously to / العطية التي تجود بها) ~ (geben, donner, bestow جادَ , schenken ) ..

(the obtaining /attainments) = (المنال ), derive from verb (نال) = (obtain, attain) semantically related to (نول = donate) antonym of (الظفر = succeed to win) ..

This word: (الظفر) refer originally to the CLAWS of PREDATORS, and hence presupposes (something difficult to attain) = (صعب المنال) = (schwer zu erreichen) ..

Needless to say, that (الظفر) as (something difficult to attain), presuppose intelligence, or imply worthiness (جدارة Wert), or it is due to, zurckzufhren auf, favorable chances ..

Hello again,

Well, my buddy Gerry has his very rare and super hard to get Grand Wing Servo (GWS) pico Tiger Moth in his hands.

Here is what I did to my buddy's new GWS pico Tiger Moth:
https://www.rcgroups.com/forums/show...h-with-Mods%21

It is my thoughts that this RC park flyer model gets it's true appeal from the scale flight manners of the de Havilland Tiger Moth produced by the de Havilland Aircraft Company - Canada.

The RC model comes with under-cambered wing airfoil and the typical Aerodynamic properties to this type of airfoil produces lots of lift at the cost of airspeed, however, this particular RC model sure does penetrate the wind when commanded. It's under-cambered properties of it's airfoil is perhaps not that dramatic yet provides an excellent Slow Flight abilities.

Another appeal, is the very light wing loading (~ 10 ounces fully flight ready) and allows for very good use of small and super efficient Electric Power Systems (both Brushed and Brushless) using small capacity 2-Cell, (7.4 Volt) Lithium Polymer Battery setups.

It is just too bad that GWS is pretty much gone and this model has been discontinued for several years now.

** Enjoy Gerry!! **

I bought an Eflite su-30 twin 70mm, and fly from grass. I couldn't get it to take off after 10 attempts. Our airfield is smooth and is with short grass. 80 meters long.
I tried everything, move cg, extend the front wheel, flapron, in little wind, and in much wind.

Is there anyone other than me, who has trouble taking off from grass? With the beautiful plane!
If so, what have you done to be successful?

Sanded everything while still in the sheets.
Pile of parts ready to go.

Getting it squared and glued to the template.

Medium CA set super fast on sanded wood! Almost screwed up the keel it set so fast.
I used Titebond III for the engine rails to laminate them together, and 30 min epoxy to glue them to the hull pieces.

So far so good.

This one looked like it had promise....until I checked the nacelles......not gonna waste material

Well SNUFF !......I've hit a snag,,a big snag....In its current configuration, there's not enough area at the nacelle inlets to satisfy the fan sweep area.....one thing I've learned about these fans.....I need to provide 100-125% inlet area, so the fan doesn't waste any energy just trying to get air to the rotor blades..in this case, I'm only providing about 70% of inlet area....long story short, the fans will starve at the inlet....

If you limit the amount of air going in, you reduce the amount of air going out......now you see why all my jets have nacelles that are external of the fuselage...e.g. the S-3, the SU-25, the A-9, and the modified CF-105
