Default My hunt for the right size inrunner motor

OK foamie glider drivers, I am looking for a 1200 kv inrunner motor for my Multiplex Easyglider. Tons of outrunners out there but so far I've had no luck finding what I want. 1000kv is a tad light but 1200 to 1300kv would be just right for max flight time for just leisurely flying or climbing up to thermal hunt. An outrunner won't fit unless I use an external mount and I want a clean profile so that's out. Any help pointing me in the right direction would be appreciated.

What are your diameter, length, weight limits? Lots of inrunners in that kV range, but sizes and especially weights are a big factor. Would a geared setup work? How much power do you need?

I think I need a signature.

This place is still having a sale on the Hyperion motor for sail planes the motors have a tapered front to fit into the tight nose of these planes. Might work and I have bought from them pretty quick shipping from Japan think it was 10 days.

Hear you go Lots of power when you need it, and it will make your Easyglider Fun to fly, you dont have to use all the extra power, but its there when you do need it This motor will turn your glider into a mild hot liner. use a 6x4 prop on 3 cells.

My EasyStar is a powered glider and uses a pusher motor mounted in an enclosed "pod" facing aft behind the wing. The motor must have a 28mm diameter and in the kv range I specified weight would not be much of a factor. I don't need or want a lot of power, any motor in the range of 1200kv up to 2000kv would work. My preference would be at the lower end of the scale. A geared setup would not work btw. I've searched dozens of retailers, large & small but so far no luck on the smaller kv ratings. I'd appreciate any finds you might come up with.

Just checked it out and they show no inrunner motors. Thanks anyway for your effort.

You're right about the hot liner part. Given the results I've turned up so far I may well have to go bigger than I want to just to get that thing in the air. Thanks for the url, I'll bookmark it in case nothing else suitable turns up.

All right in your first post you mentioned the Easy Glider this has the motor mounted in the nose. Why I posted the link for the motors. I just noticed in your other post that it is the Easy Star glider which is a pusher. Now I get ya.

look at the motor Jeff recommends for this plane you just need to make a plywood mount to fit into the pod. I bought one of his metal mounts for the HK Bixler and did a little foam carving to fit it into the pod. I am sure you might be able to do the same. By the way I swapped the motor out after the plane was assembled, so it can be done.

Here are the links for the motor mounts I used the second link for the HK Bixler. Hope this gives you some ideas.

If I go for the outrunner style that would be an excellent choice but the website shows out of stock. Will begin a search for a similar outrunner if no suitable inrunners pop up. Thanks Gramps, good find. Thank you all for your response to my plight.
