Do you like fast planes? Then you will love the HobbyKing GL-Speedy Hotliner! Constructed from ultra smooth Fiberglass, laser cut plywood and balsa for a ridgid, slippery, high performace model. The HobbyKing GL-Speedy takes a variety of 28mm diameter motors for extreme prop driven airspeed, throttle down and prepare to get addicted to those high speed silent passes!
You will require a 28XX 2800~3300kvbrushless motor, three slimline wing servos, a 3~4S 2200mah lipoly battery, a 40~70amp ESC and your own transmitter and receiver (Tx/Rx) to complete this model.
Does anyone know if the new Glider motors from Turnigy will fit? They are 38mm but no wiring harness to bend around the side, no clearance needed for the rotating can!
You could actually stuff it in the front. If its tight, that tapered down area in the front of the new motor will help, but I don't know the diameter of it???
It is a balsa rib and fully sheeted wing. Look first at the build instructions and note how the servos are mounted to the thin plastic covers with double sided tape. This method will probably pull apart with the first speedy turn. Ply mounts screwed into ply doublers would secure the servos. There are other caveats so the innocent beware!
Am I mistaken that they changed to motor requirements to a 28mm dia motor? I thought it was a 36mm listed before......I was just going to order it to use an inrunner that I have laying around, but not not sure if it'll fit???
I would not use a 4800kv motor. I'd be extremely concerned about a folding prop failing at that rpm. BTDT on a 3300 kv motor. In fact, I'd probably go slower than the recommended 2800kv. I used an 810kv motor in my Siren, which is only a little bigger. I'd probably look for something in the 1200kv-2800kv range. The other consideration is CG and ballast. For example, the Siren needed several ounces of nose weight with D540L-810 (so you can find it). It might be good to build it up, figure out how much weight you need in the nose, and then sized the motor from there.
locklear I would not recommend going much faster than 100mph with this plane as the wing is only balsa sheet over light ply skeleton frame. You will taco the wing if you go much faster than that. You really need a carbon fiber composite wing and airframe to handle the speeds you mentioned.
Can anybody recommend a good folding prop for this glider? I am planning on using a Turnigy 2836, 3200kv, or the 2850kv. 3S 35C LIPO and 60A Plush ESC. They don't specify the diameter of the nose either?
ek-trician the plane takes a 38mm to 40mm spinner. With that High 3200kv motor you will have to go with a 4.75x4.75 prop or 5x5 prop. You will probably have to get a Graupner or Aeronaut folding prop as hobby king doesn't stock these size folding props yet. For the 2850kv motor you can go with one of the 6x4 or 6x6 folding props available in hobby kings folding prop section of the website.
I have watched the video, they go with a huge 3540 900kv and an 11x8 prop. They set it up on 4S I assume it's a 60A Plush. I would have to buy that set up, but based on the performance the speed looks fun, but I don't want it to be so heavy that it affects thermalling. Unless it will be tail heavy with the small set up?
Ek-trician with the 1200kv motor you could use either a 8x6 or 9x6 folding prop and still work fine with the 40A esc. If you like to climb out then glide around go with the 9x6. If you like to stay in the throttle the a lot the 8x6 would run cooler. As far as thermal flight goes you will need to keep the weight down but will need to put the electronics and battery as far forward as possible to keep cg from being tail heavy. The esc in the video was a Turnigy Plush 60A. If you watch the video on YouTube there are links to all the components in the info bar under the video.
This is not a Hotliner reguardless of what they say. This plane is a lightwieght sport glider. It is not strong enough to handle that kind of power. You can't glass a rib & spar wing, unless you sheet it first with Obeechy or balsa. Then only 6/10oz cloth or it will be too heavy. It's also way too expensive. There are several fast gliders that can handle the speed you want on this site. I suggest you pick one of those. Remember you want a sheeted or fiberglass wing.
