Nice work Gary smiley

My build is coming along slowly..........

I covered the wing and ailerons with some left over white film I had laying around. I don't have enough to cover the rest of the model but I still need to add some finishing touches to it before covering anyway. I do have some chrome coloured film laying around so we'll see if I can make use of it.

I have a one piece undercarriage mounted up as I feel the two piece will not quite handle my rough landings!

I will be attempting to keep all the electrics hidden away under the front windscreen and 'cowling' as I cannot stand 'spaghetti' wires and batteries just hanging out.

Looks good Ross, I was tempted to do that with the u/c, that looks very neat.

In retrospect, a one piece undercarriage would have been the way to go with this model.

That said, it's pretty lightly loaded Gary so I've not had any problems so far.

I had one of those days today where I had a chance to work on the EB for a few hrs and I spent 2 1/2 hrs thinking and 1/2 hr making. I only ended up making the windscreen and cowling section. (sorry about the poor quality pic) The windscreen will be held in with some strong magnets and the cowling held on with covering eventually.

Merry Xmas to all

Here's a bit more on my EB.

I've sorted the tail linkages and now just need to get some more covering for it, hopefully next week sometime. The idea with the linkages is that they come through the framework to try and keep it neat. What is not in the pics is a section I glued infront of the horizontal stab that keeps the linkages neat, in align and partially concealed as they go under the tail surfaces. I will either leave the section of frame that they come through uncovered or put a slit in the covering to allow the linkage to freely move. tail linkages#3

Maiden flight of the Eager Beaver today.


It flew OK but was a bit twitchy (may have been my thumbs due to the cold weather) and severely underpowered for my liking . Also needed a fair bit of aileron trim sad.

Changed battery from 3 cell to 4 cell for the second flight. Added a bit of expo and set up the rate switches.

Made all the difference smiley


Flies quite well now. Took off much better than the first time at about half throttle. Flat turns with very little reverse aileron. Stall turns are pretty easy. Loops, rolls and inverted flight are no problem. Stall was a non-event, and the power-off glide was nice and gentle. Knife edges OK but needs quite a bit of aileron as expected, due to high wing. Keep the rates low and it's very forgiving - almost easy to fly! I forgot to set the timer and landed with 3% remaining, but (almost) dead still landing with a last minute bit of power wasn't a problem embarrassed. Motor and ESC were cool despite running on 4 cell, which takes the motor slightly beyond it's spec. Motor and ESC have very good cooling where I've mounted them, so this helps a lot.


Not sure how many minutes flight time I had as I lost all track of time due to the fun I was having - will check next time. You can see from the manoeuvres I've listed that I threw it around a fair bit.

I won't be buying any more 4 cell batteries, so if I need more flight time, I will fly with 2 x 4 cell 850mAh batteries in parallel - got loads of these, and I've just put a parallel adapter in my box in case I need it.


I've also sorted out the aileron trim mechanically, ready for next time.

Thanks for the plans for this unusual little model David thumbs up

Happy new year to all.

Phew laugh

With X-mas, new-years, family and work holding me back a little, I managed to get some covering to finish off my EB in there somehow smiley ................

I started with the tail sections and used the same hinge method for the elevators and rudder as the ailerons, that is, a strip of covering material to hinge top, and bottom for extra peace of mind.

Next, I started on the fuselage. What an effort that has turned out to be angry

It is OK but not the way I wished for it to turn out. Maybe it would have been easier to cover the sides before putting them together, although, it has turned out OK but not as neat as I had visualised.

Here it is so far, tail is not glued on yet and I still need to cover some spots........

Happy new year Ross, that looks smart thumbs up

Hi Steve, good stuff.

It's interesting to see all the different modifications folks are making. As I said in the write-up, it's the perfect model to do your own thing and I can see some eminently better solutions than mine! smile

Hi all,

Covering is 98% done. I thought I'd fly the Aussie colours and due to work commitments, I won't be doing anything else for a few weeks. Until then..........smiley

As you say Stephen thumbs up

Like the scheme Ross, very effective thumbs up

It'll be interesting to see how model flies Steve. I did contemplate a flat plate wing, much like the shockie that gave me the idea but I'm glad I didn't, I don't think it would have worked as well.
