Sorry for late reply.

On gliders we always want a large diameter propell and lower pitch, and not too much RPM. For sport the "middleway" is good, ie medium propeller and a pitch at 6-10". In the other end you find fans which require very high RPM and really small diameter and high pitch. Just look at the fan inside a ducted fan.
This is the reason why I asked for the propeller clearance

From the weight at appr 1 kilo I know you need at least 150 Watt to get a climb, gaining height but not fast climb.
The Nippy 1812/100 will give you 200Watt using an APC 8x6SF, and 180Watt using a Graupner CAM 8x6 folding propell. If you use a SF-propell the propell will brake a lot during flight of course. Here is a picture: http://www.mft.nu/es/product/product...207321#eximage This motor could be mounted at the front of your pod using the backmount included. It will require 17A at full gas. Or look for other motors able to run at 20A and kV-number close to 1000.

Since the Dynaflite is a bit heavier and I suppose you want to mount the motor in the nose? and you look for good climbing authority I think a brushless inrunner able to give you 300 Watt would be a choice. You don`t have to squeese all the 300 Watts out of the motor. One option which I have good experience from is the Jeti Phasor 15/4. Ran on 2S LiPo and using a 10x6 Aeronaut CAM folder it gives more than 1200 gram static and will draw appr 34A.

Only examples, there are a lot of motors out there. To get best climbs a geared setup and large diameter propell is better.
