<span style="font-size: medium;">Hi Guys,

Test flew my flash last sunday with the new wren 160 engine. CG was at 365 mm from the rear of the tip tanks. T/O flap was at 15 mm and landing flap was 50 mm. After rotation the plane took about 2-3 mm of up elevator to fly level and felt a bit nose heavy, after trimming, i had a great 5 min flight in clean configuration. After selecting gear down the plane again got her nose down which is normal. I selected flap 1 and the plane dived some more towards the ground, selected landing flap and the nice flight so far got pretty hairy with the PIOs. I was really struggling to fly the plane in landing config.
My question is if the plane is tail heavy, </span><span style="font-size: medium;">why did she take a fair bit of up trim to fly level.And if she is nose heavy, why did she go into the PIOs.</span><span style="font-size: medium;">
I am a bit confused now if i should add a little nose weight and get the CG to 370mm or remove some weight and get the CG to 360 mm, or leave the CG alone and just decrease the flap throws.
I was using flight modes on the 12x, and had trimmed the plane in clean config, so when i selected flaps i must have lost all the up trim i gave in clean config which must have added to the PIOs.

Thanks for any inputs
Chaitanya.
