Hi Tom... Thanx for the reply.. My motor mount for my pod design is adjustable , and I think since it will be flown off a runway, my first thoughts are to set the thrust angle about neutral , or maybe a half degree up.. I will see how it powers down the runway for balance and lift, and go from there.. I wonder if some of the set ups I have seen here, that are angled way back, are having troubles because of to much air getting over the tail, and not enough under it. ?? .. Ian

Hi Ian- sounds interesting. Let us know what you learn. The paved runway will help get airspeed fast. You may want to add a small nose skid to take some of the shark sniffin abuse.

Regarding your question- I think it's a few things...
A pusher engine is probally less efficient and the inexpensive setups have marginal output power. Also, most of us come to this with expectations of 3d-like power plane liftoff- which ain't gonna happen.
I've had the best continual success, on a grass field, with a 30' bunge assist. It simple and gets her in the air fast.

Also Tom,, In your pic,, your prop blades look smaller, for a higher KV motor?, Am I correct??.. My set up is configured for a 1200 kv motor, with a thrust to weight ratio of around .8 - 1.. I'am definitely putting some road rash protection under the front also , and it will have wing tip skids.............. Your plane plane looks pretty cool.

Hi Ian-
I'm on my third motor now. The stock didn't last long. I'm currently using an NTM 3548-1100kv rated for 640w@4S. The prop is a 10.5x6. It motor cost $25 or so. Also, a great $3 espritmodel(fr top model) fiberglass piece keeps the prop aligned. My bungee hook will take some of the fuse abuse (if I try a liftoff without the bungee).
Good Luck!
