June 25/16

Today was supposed to be a scheduled “A.L.E.S." contest. Well, that was the plan anyway, It was to be our first contest at our new field location. It was a perfect summer day for an r/c flying contest. Bright sunny skies, light winds from the northeast, temperatures in the 24-29 C range, couldn't ask for better conditions.

I arrived at the field at 8:15 am, already the club prez and the contest director were hard at work setting up shade canopies, laying out the pit area and setting up the flight line. I brought my canopy and table and set them up as well. By 8:45 am we were ready to let the games begin!

Only one problem……no contestants!! W.T.H.? In retrospect, there was so much going on this weekend, a large scale r/c event in nearby Stoney Creek, an r/c tow plane & glider event in Fergus, just to name a few. I guess we should have expected a poor turnout but to be honest, our club has always had good participation at previous events. By 10:00 am. there was only four pilots in attendance plus one other member & his wife who turned out just to see the new field. Also, yours truly with nothing to fly and only my camera in hand…..bummer!

At this point, the CD said “you know what?” “I think we shall just have a Fun Fly and enjoy ourselves!” What a great idea! So that is what we did.

We had such an enjoyable morning! The four pilots got to practice their landings and fine tune their aircraft while I got to practice my r/c...Continue Reading

Loaded up my repaired Hk Cumulus plus all my other flying gear and headed to our new flying field 3.9 miles south of the Hamilton Airport Tower. I stopped off at Walmart & grabbed a 10’ x 10’ portable canopy that was on sale for $98 Cdn. What a godsend that turned out to be as it was a real scorcher with a high of 33C!

Seven members also joined me, so we ended up with Gentle Ladies, High Risers & Supras running on the hi-starts, plus two full house 4 M Electrics, as well as my HK Cummulus and a Whippet DLG. Lots of room for everyone at the new field! : )

I like to come prepared, so along with the new sun shade canopy, I brought my folding 6’ work table, a cooler full of drinks and sandwiches, two folding chairs, my radio & charger metal briefcase, HK Cumulus mounted on top of my field box. It takes a while to set it all up but its worth it imo, having a comfortable environment to work in with all my tools close at hand.

I finalized the setup on the Cumulus, performed my radio check, ran through my preflight check then headed to the open field. The wind was picking up around 15- 20 Kms/hr. but steady from the south west. I had to add another 5 gms to the nose to compensate for the repairs to the boom. I managed a gentle throw and the Cumulus floated beautifully. I stayed out on the field tossing the plane for about an hour until my heel spur started screaming at me…..time to take a break! First time the plane has outlasted me! Lol!

As luck would have it, I woke to find the air absolutely calm! Hmmm…..time to go flying! However, the “Commander in Chief” intervened with the need to be driven to the grocery store first! By the time, I returned, loaded up the plane and drove to the nearby covered reservoir, it was 11 am. The temperatures had risen to 30 C and with it, the incessant wind, which was gusting from the east at 15-20 Kms. Dang not the best conditions to testing my HK Cumulus DLG!

Following the advice of some fellow chuckers on the Hand launch forums, I decided to add a thin ribbon of lead weighing at exactly 5 grams to the nose of the plane. I also rechecked the aileron differential setup again and sure enough….I had the settings reversed! Doh! Also, performed some more adjustment on the right aileron to line it up with the wing.

The good thing was the grass was getting on the long side at the reservoir which makes for softer landings. The bad thing was the wind speed had picked up and was gusting! Horrors! I don’t feel comfortable launching and testing a new bird in such conditions but I was here now…..so I decided….let’s go for it!

I was delighted to see the Cumulus actually fly like a DLG is suppose too! I wasn’t throwing very hard and so I wasn’t getting much more than 30 - 40’ of height. Non-the-less, it went up on the shelf quite well and penetrated the wind with ease! I actually had it hovering in the wind at one point.

I got in about 10 good chucks and was...Continue Reading

Due to the pressures of family life, I was not able to get a chance to assess the damage & come up with a rebuild plan. To be honest, I couldn’t look at the wreckage for a few days anyways, too upsetting, so it all worked out I guess.

HK Cumulus 1.5 DLG:
I had to re-install the rudder & re-enforce the joint with 3/4 oz cloth and used medium CA this time to glue it all down. I did both sides and it does seem stronger. I put an extra layer of packing tape on both sides of the bottom of the rudder to give it a little extra strength when contacting the good old Haldimand clay. I'm keeping my fingers crossed!

I noticed some play in the port side aileron connection so I removed both wires and installed heavier wire with adjustable Goldberg connections on the ends. That took out the play, so that should be good to go!

I then set up some aileron differential, and reduced the aileron movements by setting the D/R percentages to 70%. I then got the flaps to work off of the VR (variable rate control) on the transmitter. Next I set up the ailerons for adjustable braking using the left turn portion of the VR knob. I also set up the telemetry so that both the transmitter and receiver voltages are visible on the transmitter as well the audible and tactile warning systems for low voltages.

Lastly, I checked the CG and found the balance point to be just a few mms behind the recommended balance point. I plan to leave it there and just try some...Continue Reading

After experiencing some high winds the past few days, I was excited to wake up this morning to very calm skies! I packed the van with my new HK Cumulus 1.5M DLG & my retrofitted 2M Aspire Electric Sailplane. Next I picked up my r/c flying buddy Terry and headed out to the new field. The president of our club was already there when we arrived and reviewed the procedure for calling the Hamilton Airport Tower prior to commencement of any flying.

The pres was flying his old school Lanzo Bomber fitted with a small 100 watt electric motor. That plane is so light it just takes off like a rocket and floats around forever on the slightest thermal.

I dragged out the work table & chairs and proceeded to prepare the Cumulus for its maiden flight. The first thing I noticed was how much more awkward the 1.5m DLG is to launch compared to the 1M versions. Also, how much more energy is required to get any appreciable height!

I only managed four flights and with the use of the flaps was able to make some fairly slow landings. However, the soil at the field is the notorious Haldimand Clay and when its dry it can be like concrete. On my last chuck, I thought I made a reasonable landing but right away I noticed the tail feathers had broken loose from the boom! Thus ended the flying lessons for this bird! : (

Next I worked on my retrofitted Aspire. Over the winter, I had removed the old 550 brushed motor and heavy 3,300 Mah. battery. This was replaced...Continue Reading

Well, I’m back from my three week west coast adventure! For today’s blog I wanted to talk about my r/c club.

The Southern Ontario Glider Group ("SOGG") was formed in 1984, (making it 32 years old, if I did the math correctly!) and later was Incorporated as a not-for-profit organization in 1993 (becoming “SOGGI”). SOGGI currently runs about 35-40 members. We hold monthly meetings from September through to April, leaving the Spring & Summer months for flying! As you can imagine, some of the older long standing members have seen a lot of changes in the R/C Universe since the formation of the club! I joined the club in the fall of 2013 and have also witnessed some amazing changes.

We fly from sod farms because we need the short grass to land on, not having any landing gear. We fly free flight, hi-start/winch launch gliders from 2M to 4M, Electric gliders and DLG’s. For a number of years, we flew from a triad of fields all fairly close to one another just southeast of Hamilton. As sod was removed from one field we moved on to the next. Then development reared its ugly head and the unthinkable happened…..we lost the use of our fields!

I have to commend our executive committee that spent countless hours procuring a new site….another sod farm! The only downside was it was only 3.9 miles from Hamilton Airport and thus it fell within their control zone! With all the hoopla about wayward drones, the situation didn't look promising! Working...Continue Reading
