A little windy for video but here are the results:

I haven't quite figured out YouTube so I haven't uploaded the HD Version successfully yet. The camera recorded the flight in 720P but I have to compress it slightly to get it to upload. Will keep trying to get the better version up.

SDP!!

Nice video!! I wish I could fly that well!! That looks like a great flying field, no huge trees, & the cacti look to be the tallest things around. (Except for that windsock)

If you get a plane in a tree here, it could be as high as 150+ ft.

BTW! Very nice craftsmanship on the electric conversion!!!!!!!!!!!!!!!!!!

Jimmy

Thanks for the comments. The windsocks are usually not a problem. I made a "Pitt Pass" at the request of my flying buddies who wanted to get in the video. You can seen them sitting in the shade as I flew over the awnings.

Nice flight with my Watt-BOT a couple days ago. Winds were less than 5 kts. and the thermals were in the trashmover range. Launched right into a boomer and nearly specked out after a 30 second motor run. Touched down 1 hour and 15 minutes later on the one motor run. Gotta love it!!!

Default aluminum firewall

Hello sundevilpilot, Thought you did the best job of all the elect conversions out there and i followed yours. Instead of making a wood firewall i wen't aluminum as wood will wear out and crack. Also i had a spare fusaloge that cracked last year and i fixed with fiberglass and want to tell everybody out there to fill the rear of the fuse with (hard foam)as this will reinforce it and not break into on a rough landing and does not add much weight to the overall .

Thanks for the compliment windyhill. Yours looks like it is coming along nicely. After I built mine I determined you don't need to attempt to save weight in the conversion process. The new motor, ESC, and battery will weigh less than the slug of lead removed from the fuselage so you will ultimately be putting it back via lead. The aluminum firewall looks like a great idea. Should be plenty strong.

When I made my firewall I glassed the outer facing side of the firewall with fiberglass and epoxy so hopefully I will never have a failure.

Be ready to answer a lot of questions when you take the plane to the field. People seem to gravitate towards the Bird of Time and want to know how it was converted to electric.

Only hurt for the 1/2 half.

Brings back memories of my two "Viking" 10 foot wingspan sail planes I built in the 1980's. Got tired of trying to find a field big enough for a winch, so one of them was converted to electric power with an Astroflight geared 40 motor and 18 2400 RC 2400 Nicads. That electric model wound up with a number of two hour plus flights over the 10 years I flew it.

I actually shot about 30 minutes of movies with it, using a super 8 MOVIE CAMERA! Those movies have since been converted to DVD, still got them.

It got sold to a club member, who after a year or two sold it by Ebay to some person in the East Coast of the USA.

Default kite launch

This will be the first time i have ever said anything online to anyone but you could launch a small sailplane from a kite. I also fly a 8ft delta coyone here at the ranch, the trick is the KITE! the delta is a tri kite with wings and is the most stable kite made and it takes a strong wind to get them up over 1500 to 2000 ft. A large rip strip (velcro) on the front of the nose and 15 ft of cord atached to the kite. I have a large reel to get all the line out and back. here is a telaphoto shot with an eagle around a 1000ft. I have been working on the idea for a while but not yet taken the plunge.

You probably could but if the wind was enough for the kite to take the glider up you could probably just hook the glider to the string as if it were the kite and leave the kite out of the picture. With enough up elevator the sailplane would act similar to a kite.

Smoked the HURC 3536-10 motor in the Watt-BOT last week on climbout. Not sure why,but this is the second motor of the same flavor that has gone wobbly on me. The other was in a totally different style of aircraft (read:non-sailplane) so the BOT installation is not the prime suspect in the motor smoking caper. So beings I have to repower I have decide to go up a step to a HURC 3542-11 motor spinning a Aeronaut 11 x 7 folder and a 60 amp ESC. The motor dimensions are similar and the weight is 30 grams more ,but I have lead in the nose that can be removed so it should work fine. The additional power will be very welcome as you can never have enough.

Question:
How much does that motor weigh? And how many watts are you running through it?

Just my personal opinion, but any motor that is running way over 100 Watts per ounce of motor weight, is running that motor pretty hard. Regardless of how the motor is rated by its mfg.


My Hacker motors run around 80-100 watts per ounce of motor weight, and they only get slightly warm after a flight.

Just read this thread. Very nice job on the conversion.

Have you ever weighed the plane? I believe that it is targeted at 60 ounces as a pure glider. Wondering what yours came to, all up, with battery and all.

Great build thread SDP. A friend of mine sent me pics of his BOT and now I am thinking about getting one myself.

Appreciate you taking the time to post your conversion process.

Thanks for the compliment Frank....

I fly my Bird of Time quite often and each and every flight brings a great amount of joy. There is just something about a large yet simple glider just floating around. Every time I fly it I get a large number of guys watching it and asking questions. Just pure and simple.

Everyone has their own theory as to what is a "Good Charger" so mine is only a recommendation of my experience. I have been using a Triton 2 charger for a little over two years now to charge all types of batteries. It has served me well over that time and seems very versatile.

Excellent answer. (even though I don't use that charger, I like the way you said that).

Default li polly charger ic6

got this charger from hobby lobby and am imprtssed, does it all and comes with all the atachments including temp sensor. Sky rc makes it and when you get it in the mail it has a holligram on it and you scratch it off to get the code and go online to varify it is genuine not a pirated copy from china.

This has got to be the best illustrated conversion, good job. Could you tell me what the measurement is from the canopy opening to the firewall is?

Thanks for the compliment!

I measured the length of the nose from the firewall for you. Measuring from the firewall to the beginning of the canopy (Where the fuselage drops down to allow the canopy to flush mount) is 2 inches exactly. I ended up at 2 inches because that was the point on the nose of the aircraft that allowed the motor to fit while removing the least amount of nose.

Hope this helps,

Phil
