Plane won't move forward after "I" key
 

Ok, take off really stumps me;

1. Open fuel ****
2. prop pitch 100%
3. magneto M1 (already set)
4. radiator open 50%
5. trim oil cooler
6. Flaps 20%
7. Throttle 10%

Hit "I" switch to start engine.

Trouble is I do that and once engine starts I push throtle forward but the plane doesn't move. Brakes engaged? What key is brakes?

Regards.

Prop Pitch
 

Check your Propellor Pitch - set to 100% - oops! you said you did that! That is the most common fault re your description, set it to zero just in case there is an issue. If aircraft shudders it could be because engine is not warm enough (brit - 30C). I'm presuming the engine revs higher when you push the throttle!
