Engine list

I’ve recently completed a move to electric for my entire fleet so I thought it was appropriate to tidy up the IC engine pages because they won’t be seeing much of an update in the future. You can see the full list, with links to details about each engine here.

New Shed

29-280-210-0-0-280-210I’m a bit behind in updating the blog, but I thought it was about time to have a bit of a spree. Last spring I took the sledge hammer to the old shed which we inherited when we bought this house.

There is a very useful (maybe 12′ wide) path down the side of the house, between us and the neighbours where the previous owner had a couple of sheds. One of these looked very recent and in good condition, the other looked, well somewhat worse for wear. I had hoped it would last a season or two, but after a couple of weeks of rain everything inside was either sodden or mouldy, so a plan was hatched to replace it come spring.

As luck would have it just before the new shed was due to arrive I had a guy come to replace the rear fence, he was happy to remove all the bits of the shed with the old fence, which left me a nice clear space.

$_57I bought a 10×5 Pent shed which is the biggest which would fit, managing to find one with doors in the long side, which meant I could use all the space available to me. A bit of wiring and a new bench later and it was starting to look like a proper shed.  This online guide suggested how to make a handy model rack, so I followed their guidance and a good chunk of the fleet are now happily hanging up. I was going to build a bench, but the one in the picture on the right was a kit on ebay for 30 quid, which I thought was reasonable, so that made a welcome addition.

Couple of new Lego sets

42028_Webfiles_SECIMG2Over the few months a couple of new Lego sets have come into the house. First the latest Lego Ideas set; the Birds, these are amazing creations, looking more like ornaments than Lego. We’ve built only two so far, only the Robin remains to be built.

Next up is the Lego Technic Bulldozer, I’ve always had a soft spot for the Technic building range and this was a nice edition. It is proving to be robust enough for the kids to play with constantly without bits falling off, so we all win :)



I’ve hauled the S-Pou out of the loft and intend to start flying it again at our clubs indoor evenings. Hence I’ve moved its page out of Historic and into the RC Aircraft section and updated it accordingly.

I’ve also added the following new kits to the Lego page:

Hopefully I’ll update the blog more often in 2015, I’ve written quite a lot of code recently, and done some cool things with my Raspberry Pi. I must also try and write up the renovation of the Sea Rover!

Mini Tyro electric conversion

Airframe finishedSo I’ve made some progress on my electrification of the Mini Tyro. After a bit of maths and some guess work I ordered a D2822/14 1450kv outrunner and a Turnigy 18A Plush. The plan is to try a APC 8×4 and a 7×45 prop on it to see what power it draws.

I made a start by removing the Mills from its mount and cutting a hatch into the wood above the tank. Then the tank was removed and the tank bay floor cut away. The next step was to remove the old firewall because it was too far back to mount the motor on, I could have used standoffs but that would have left a rather small bay behind it for the battery. A new firewall was cut and installed about 3/4″ further forward than the old one. This gives a sensible clearance between the front of the fuselage sides and the rear of the prop but also has some room for adjusting the right/down thrust

D2822-141450(1)As it happens the battery needs to live under the wing, but the space previously occupied by the tank is a perfect home for the ESC, with the Receiver living just behind it, slightly in front of the wing.

The battery has quite a lot of room to move around under the wing so it will need some sort of restraint, some velcro is likely.  The front end needs tidying somewhat, the covering is looking tatty and I’ve yet to make a cover for the tank, now ESC bay.

Having said that, I’ve weighed it and run it up and all seems fine.


Complete airframe minus battery is 259g

The 3S 500mAh battery is 47g

The 3S 850 mAh battery is 67g


Using a 3s and the 7×4.5 prop it pulled 5.9A /  57W WOT. Giving roughly 79.3 W/lb which is probably about right for the little Tyro. I expect the 8×4 might give a good bit more and maybe even too much. We’ll see!

I’ve yet to test the 8×4 because it needs reaming out to fit the prop adapter.


I’ll post some pictures when its finished, although the temptation to fly it as it is now is quite large!




PKZU1480-1-ultra-micro-pole-cat-bnfI bought this model just before we started packing to move house, so it never had many flights. I grabbed it mega cheap at Wings and Wheels thinking I would probably fly it a few times and then gut it for the electronics which would go into another of the excellent Stevens Aero kits. However life got in the way, and then we moved and now I have nowhere to fly indoors. So sadly it sits unused in the loft. I’ve yet to decide its fate! Although writing this I think maybe I ought to get it out and fly it in the field on the way to work on calm mornings :) Until then, I’ve moved its page into the historic section.

Beaver – adding some colour

After a bit of coding and a weekend away, I’ve got round to spending a bit of time with the Beaver. Next step is to add some colour, I didn’t take any snaps of it in its plain white state, but the shot below shows the wings masked up and the blue applied.

I have since removed the masking tape and left it to dry, tomorrow night hopefully I can get the blue onto the fuselage.
