Status: offline 		Easton, what is the weight of your spitfire with the g26? I'm waiting for someone with the spe 26 to chime in. I wonder how much perfomance difference between them. Power and weight.

CG position is 4" from the leading edge.

Ailerons 3/4" up & down

Elevator 1" up & down

Ruder 1 1/2" each way

This is as they say in the instructions as a general guide.

Status: offline 		Specs:

Futaba radio gear

Laser 100

14/8 three blade prop

Uni-tract Air up & spring down retracts

As to the engine positioning I found and marked the Horizontal & Vertical line and then the engine mount six millimeters to the left giving me the correct amount of side thrust.

The paint was Flair or Spectrum http://www.flairmodels.co.uk/Finishing/Spectrum.htm

Status: online 		OPkay, I finaly got mine in the air, with the SPE 26 and a 18x6 prop...It flies like a dog, lumbering around, in a high Alpha attitude. I keep thinking she's gonna stall out on me.
Both times the engine ended up quitting on me and I've dead-stiched her safely back, but I can't imagine it's th eplane... It must be the engine.
I can't figure it out?
I started out w/ a 15x 7 3 bladed prop, and it was a slug so i changed her tio the 2, but I still am not getting the love I want.
CG is correct, but it flies like a .60 is pulling it around.
Anyone else w/ and SPE 26 on board ?
What is anyone turning RPM wise ?

I'm still hoping to hear from anyone with experience using this engine

Status: offline 		No way a 18-10 is too much prop for a 26. Try a 16-8 apc. I have one on mine with a g26 and it turns it 9200 rpm. Mine flies great. I like the way it flies so much I upgraded the retracts with robarts and struts and 3.5 robart wheels. Just try a 16-8 apc and you can compare the rpm and if it anywhere close it should fly great.
Good Luck
Nelson

Status: online 		I'll be trying a 16x10 3 blade this weekend, since I still have the bigger/ longer parabolic spinner and I don't like the factory version.
