Using an electric plane makes this even easier as the preparation between flights is simple and while you are hooking up etc… you are burning very little “fuel” so more tows between “fuel stops”. I’m looking forward to more glider towing. It does make for some “exciting” flights for all concerned!! We are investigating but we are pretty sure either the wing or tail incidence is off or even variable due to damaged mounting hardware at the back of the wing. One of the two KA-8s I was towing had some pretty nasty habits when in tow. I was a bit concerned about whether it would hold up but based on this video it looks like we are in business.Īs you can see, no all glider tows go smoothly. It did necessitate notching into the trailing wing edge right at the root, but on this aircraft that is simple enough. It was easier to mount it just forward of the bulkhead near the trailing edge of the wing than to build out a bunch of new structure so that’s what I did. With a little radio magic, assigning a channel to a switch, setting endpoints etc… and you are all set.Īside from getting access to mount it, nothing really difficult about the process.

Once the release is mounted, install the servo “tray” and cut the rod to length. In my case I mounted this tray across the body with the servo shaft pointed toward the rear of the plane to give a nice straight up shot through the release. Mounting it requires getting a good grip on the nuts on the far side so forceps to the rescue!Īnd the construction of a tray for the servo to run the thing. To do that requires access to the other side so cut open the bottom… I want to install it just ahead of this bulkhead near the trailing edge of the wing This one is made by TopModel and is very stout but not extremely heavy. I found a nice release to use and with a little surgery it was firmly ensconced in my airplane. The Telemaster only weighs about 5.5 lbs ready to fly so pulling a couple pounds of glider is fairly effortless. This combo, powered by a 6S battery (usually a 4000 but now frequently a 4500mah) has a lot of pull to spare. 80 motor along with a Talon 90 speed controller. Partly I did this because I could and partly it was because I have a couple of fellow RC club members who own gliders that I have towed up before and I sold the old tow plane (the Carbon Cub) so felt like I needed to have a replacement. It is really just a circular collector, but at least the rotor is off center.I recently installed a glider tow release into my Telemaster 40. Is there a seal on the motor shaft? No - it relies on the bearing to keep water out of the motor.ĭoes it have a volute? I'm going to give it this one. A heck of a failure for a pump advertised as 'brushless'.Īre the brushes at least carbon? No - just copper It looks like there was an excess of grease on the brushes that caused poor commutation. I did an autopsy on the pump to see what went wrong.

The pumping was 0.43 gallons per minute, down from the 0.6 gallons measured with a less restrictive outlet. It ran reliably, drawing o.4 amps under load and around 0.15 Amps unloaded. It continued to be erratic and use a lot of current. Since I'm not one to give up without a little trouble shooting, I filled the ship with water and ran the pump for a while. I put a watt meter on it and it had very high no load current. The first time I hooked it up the speed was very erratic.
