I came across these earlier this year at the AMA Expo East. They are made by the following company, E-aeromotive.com, run by Dennis Andreas. I grabbed a couple to bring back home to fool around with. A few weeks later I took them an indoor free flight event I was co-CD'ing and they were a big hit. I gave some to kids who came through, and a few to other modelers. They really do glide very nicely indoors, an easy 30-40 feet nice and level.

They come in foam sheets very similar to depron, but a little more flexible. The sheet is a about 11 by 14 and has 5 pieces laser cut into it. The pieces pop out and go together very easily. I've used Foam Tac and tape to put them together. I'm going to experiment with making them a bit lighter, not that it really needs it. Also, I think I'll make a notch to let these be launched with a rubber band/catapult.

I ended up buying 100 of these they were so much fun. We'll save some for give aways at events, perhaps for some classroom/Cub Scout demonstrations as well. They would be a great little fundraiser too at events for clubs, they are less than $2.00 and could easily be sold for $3-5 bucks. Id' rather have this than the small balsa planes that break almost immediately.

We had some fun painting a few up with some old paint and stickers we had laying around. We'll use these as our display models at events.


Once built, the plane is about 13.5 inches long, and has a 10 inch wingspan.

Dennis can be reached here. I have an order in for some more of these which I believe he makes to order. Shipping is pretty reasonable too depending on how many you buy.

*I paid for these items, I'm not affiliated with the company in any way other than buying from them and enjoying their products.

Make Your Own Inexpensive Centerburner

I have a dozen or so EDF models, most of which are of types that were/are equipped with afterburners. After buying some LED “centerburner” systems, I decided to see how hard it would be to make my own.

This project requires soldering skills, and access to a 3D printer and simple design software (such as the FREE https://www.tinkercad.com ), This article only describes the electronic part; fabricating the adapter to mount the LED unit to the EDF motor is not covered. Anyone familiar with 3D printer design software should have no difficulty in creating a suitable mount. Total cost of the electronic components for the system is less than $16. If you do NOT have these skills, I suggest you buy a ready made unit from one of the people who market them on rcgroups.com.

First, I found a suitable high output amber bulb that has it’s own inbuilt voltage regulator.
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

This is very bright, and runs on anything from 9 – 30 volts. It’s current consumption when full on is only 300mA, and the four brightest LEDs are behind a lens that directs their light along the bulb axis. With a little fiddling assisted by a razor saw I was able to remove the yellow plastic bulb base and expose the inbuilt regulator and its connections. These bulbs are $16 for two at Amazon.

To control it without making a custom controller I found a 10 Amp ESC for BRUSHED motors. $...Continue Reading

The DJI OSMO ACTION

In a rather leaked release that may surprise some and not so much others DJI, the worlds largest drone manufacturer have announced their latest product in the OSMO lineup, the OSMO Action.





The original OSMO launched in late 2015 and was DJI’s first move into ground based cameras with it being fitted with a version of the X3. Since then DJI have diversified the line with the OSMO Zoom as well as the Mobile versions for smartphones. In November 2018 DJI released the first major over hall of the line with the OSMO Pocket, this dramatically smaller version was entirely redesigned and improved in almost every way while still keeping the benefits of a stabilised gimbal camera system.






Today DJI have added an entirely new model to the OSMO line up. The OSMO Action is as much a side step as it is a step forward and takes them into the action camera market properly for the first time and in direct competition with GoPro, SJCam and Others.

Back from holiday and go some lovely weather for flying yesterday so went up to the park to give this R349 a go, a bit tentative flying because I'm not so used to this yet but once I do ....
Quick review, this is fast and fun and cheap, needed props changing from the 3028 to 3042 or 3052 and a bit of a tune up to fly how I like it, great on 3s or 4s, has good camera and is well under the 250g weight with batteries , flight time of 3 to 5 minutes depending on which battery I used.
More detailed review and pids to follow.

Things just don’t last… The original garage door in this ‘62 house started falling apart on me. (No, I didn’t acquire it when I was 10, we bought it in ‘91.) It was a traditional four panel design with glass at eye level. It was pretty heavy. The glass had been painted over before we got it but that just provided privacy, the infrared light came right through and it could be very hot but it worked well enough. Until the end of April.

I had just unloaded from a day at the field and went to shut the door. About 3/4 of the way down it jammed. When I pushed a little harder, the bottom ripped off. Time for a new garage door. Before that could be done, I had to clear out the back half of my shop. All airplanes were moved to the TV room or stored in my minivan. The building board were covered boxes and tools.

It took a while to coordinate time with my son-in-law but we ( and by “we” I mostly mean him) got a new door installed. I got an insulated four panel from Lowe’s. It’s much lighter than the old door and the insulation is a godsend. It may be spring but a west facing garage door gets hot pretty easy.

This is my busy travel season but I finally managed to get everything back in order and working on models again. Besides putting in a new door, I have also been doing some rearranging to get more useful space that had been lost to, essentially, inertia.

Its funny .. in every Forum there is often one that seems oblivious to world around them. With Jo - not only blind but paranoid !

Yet again - he attacks me for what he thinks is a post targeting him .... why would I target him ? It has no purpose - I long ago got tired of winding him up. I can go real fishing instead of baiting hooks for Jo !!

RCG is the last refuge he has after being booted of various other forums ... he denies it - but its common knowledge.

Hang in their Jo .... they haven't thrown you out of RCG yet !!

I turned 63 in January .... but in fact only when climbing stairs do I feel old !

But my flying standards are getting worse. I swear I am going backwards ... especially when it comes to landings and such. Major problem is 'depth perception' - I swear I am lined up with runway ... but find myself landing into the rough !

Maybe its my glasses ?? I wear varifocal glasses having got fed up carrying two pairs, one for normal and others for reading.

I must say though ..... my flying today is improving my repair skills !!

Gentlemen :

Those of us who use 3D printers for making model parts know that most of the plastic filaments we use pick up moisture from the air . (Agroscopic) Filament manufacturers go to great lengths in their packaging to combat this with the inclusion of a small bag of dessicant and vacuum sealing .

One of my mates was throwing out a small wine cooler fridge as it had a busted door bracket and would not seal properly . I rescued this unit from going off to the landfill and quickly repaired it . Plugged the cooler / fridge into the mains to see that it worked . This cooler uses a solid state PELTIER juction module as its cooling element and has a heatsink and fan to aid the heat transfer process . Knowing that the Peltier junction can transfer heat form its surfaces in either direction by reversing its power connection polarity , immediately suggested an obvious mod to make it either cool or heat the interior . A simple DPST relay of a 12 volt DC coil voltage was chosen for this quick mod . The relay was wired up using 2 sets of contacts and was placed into the circuit where the main power supply feeds the Peltier element . A toggle switch is used to energize this relay for the heating mode . I tested the cooler's operation with this mod in both modes to find that the interior temp reached over 40 degrees C after only an hour in the heating mode .

An overtemp safety problem occured to me which should be addressed . Not wanting to fool around with the existing...Continue Reading
