So...after demolishing my HK Sbach the other week, I am in the market for a replacement plane. Due to customs fees on things over $US200, I have limited my options to the following:

Nitro Model Thunderbird http://www.nitroplanes.com/90a287b-t...white-kit.html . Just seems like a great price.

Goldwing Sbach http://www.generalhobby.com/goldwing...lue-p-357.html can't tell what version this is or type of hardware quality.

Skyline Edge http://www.generalhobby.com/skyline-...ane-p-471.html (I have the Skyline Sbach 70 and am happy with it).

Would love a 3dhs 72 Extra, but I know that it will end up costing well over $US700 - $US800 by the time it has cleared customs and air-freight.

Any opinions on the above? Sandy

Update on the engine for the Decathlon. Well it arrived quicker than I thought with an additional postage charge of $US205 as it was reeking of gasoline and the engine was not inside a plastic bag. Apparently the courier company were doing me a favor, as sea freight would normally have a minimum charge of 200LB @ $US1.95 per LB.

This is my first PTE and it was supposed to be 'NIB' factory tested. Can anyone tell me what version I have? Quite confused with the engine. The compression doesn't seem great and the mount area / prop hub seem quite scarred with usage, as does the IE unit. However, the stand-off’s, spark plug & muffler itself do not show any sign of usage. Got to say...the weld on the muffler is simply dreadful. Do they really come out of the factory like this?

After wrecking my Sbach last week, uncertain as to use the DLE30 that was on there or give this a go.

So, that was an interesting weekend. I had heard about an RC field in Santiago which is about a 90 minute drive south from where I am. Quite excited as it would be my first flight of ‘asphalt’. I use the word loosely. I had been told that the field gets quite busy, however as it was a bank holiday weekend, they all seemed to have been elsewhere. Shame, it would have been interesting to see what others are flying and talk to them about how they get there planes / parts into country economically.

Took with me the DLE30 RV8, DLE 30 HK Sbach & Saito 91 Skyline Sbach. First flight, new field and my first perfect touchdown on to the tarmac. This was going to be a good day. Anyway, the video tells the rest of the story. If anyone is interested in the take off space needed, climb rate on the RV8 with a DLE 30, it’s there. Also, the most juicy HK SBach 30cc faceplant at 2:49. Enjoy!

Santiago, Dominican Republic, RC Flying Field (9 min 30 sec)


Post accident analysis strongly indicates a complete failure of the ignition / radio. Using a opto kill, so suspect a radio brown out. First time ever experienced this using a Futaba F617FS rx. Survivors were the cowl, canopy, elevators and rudder.

By the way, progress on my Decathlon build is on hold. I purchased off the classifieds a PTE36R to replace the planned RCG50. However, my mail forwarder in Miami is being a git and insisting that it has been used and there is gasoline in the engine, so they are going to sea-freight it at an additional charge of $US205. Really annoyed about this. Have purchased 5 new engines this year & 4 used without any issues. Won’t be able to dispute anything with them until I get the engine in my hands. I spend about $US1200-$US1300 per month with this company shipping in items that simply cannot be purchased locally. Needless to say, I am looking for a new mail forwarder. Lots around to choose from, but it is going to be a PITA to tie up my paypal / US account to the new address. Fun & Games!

Making a little headway with the Decathlon. Went with option B and removed the front top section, dowels in the old holes. Waiting for the PTE36 to turn up. I

Wings are almost done, just need to figure out the wing tip ends (Wings are huge together).

Mounted the wing and put in the dowels / tapped holes in ply plates for the wing bolts.

Unless you have a large drill press with variable degrees which will take in the Decathlon or have the steady hands of a heart surgeon ignore the "HINT" on pt 10 pg. 23. I made a real pigs ear of it at first. 2nd time round, I went with a traditional tap set. Worked out much cleaner and holds the wing in place.

Finished sheeting the top.

So...yesterday I made the stupid mistake of putting on the front top deck on the Decathlon, thinking that the arriving pitts muffler would solve all my problems with regard to the narrow cowl.

Nice squirt of windex and the balsa almost forms itself in to the required shape.

Picked up the muffler this afternoon http://www.sdshobby.com/dle50dle55da...pe-p-1796.html ...it is still too wide for the cowl and worse... the muffler pipes will not clearly exit the area below the firewall.

Even worse, I have the top deck in place and glued down

Options?

All will require carefully taking off the top

A) Extend out the firewall by another 1/2" to allow the pipes to clear the bottom of the firewall. + cut a huge whole in the side of the cowl to allow the side part of the exhaust to extend out of the cowl. I will need to think of something to keep the rigidity in the cowl.

B) Got a line on a PTE36RA in the classified today. So...after taking off the top , fill in the old holes with some dowels and then place this engine in.

Not looking forward to taking off the top

So, finally got round to shaping / sanding down the leading edge of my Dynaflite Decathlon wing. A lot of dust, but quite satisfying in the end.

For the first time I can remember, I came back from the field with nothing to fix this week. I couldn’t test the guardian stabilizer as it was violently fluttering my servos on the RV8, so removed it. I will place it in to a more simple 4ch leccy plane, probably the Dynam Sbach or 3DHS 41 and see if it works normally on those, if not…send it back to get a replacement.

My buddy’s kid got a new toy! A nitroplanes Katana. Looks really nice and flew good until an unfortunate incident. The pilot is blaming a electronic malfunction. Here’s a couple of shots of the pre-post father and son moment.

The RV8 is incredible in the air on the DLE30. Really flies nice and scale once in the air. The take off’s are a bit violent as the tail comes up too quickly and you end up loosing the wheel control. So you just have to point it in the general direction and give it full throttle. I know my buddy took a vid, so will try to post that later.

As ever the Phoenix Edge is a real honey in the air. No bad behavior what so ever. On the OS 4T 70 and with the std. fuel tank, getting about 25 min flight times. This engine just sips fuel.

My Dynam Sbach does not have a landing gear. I had read that these were quite weak. Fortunately, my buddy’s 7 yr old sat on the plane on it’s maiden day at the field when I first got it, hence I do not have to worry about it breaking off anymore.

2 firsts today:
1) nothing broken
2) I hand started the DLE 30! I normally use an electric starter, but am getting braver in my old age.

Thought I would start this blog about where my interests in RC were founded and try to continue it on to what I am currently up to and then try to keep it going.

I remember when I was a kid, there was park near school called Scratchwoods, Mill Hill, NW London (England) and some beardie people used to fly their control line airplanes there.

Absolutely fascinated with it and used to beg my dad to take me to watch, but he wasn’t so keen on the smell and thought it all looked too dangerous. Asked for some rc type gear for my 9th birthday and ended up with a 3 ch red Lamborghini from Hamleys, London. Took it in to toy day at school and a friend turned up with a 4 channel van. My goodness, he could also turn left! I was out in the cold and none of the girls talked to me again.

FF 30 yrs, found myself with some time on my hands (living on the north shore of the Dominican Republic now) and access to a friend’s farm. Got in to RC flying. Not going to say self-taught, as I really haven't got a glue and no else I know in the area has either. So, we are all just 'fooling' around and having fun.

Got in to RC gas boats quite a bit, but that seems to have tailed off over the last 2 years since I got a hernia (bending over and cranking those pull starters is a killer).

Determined not to have an operation in this country, so will try to plan something when I visit the UK next.

About 7-8 months ago, I came across a couple of people that are interested in planes, so my...Continue Reading
