| well not sure it will be ready for the week end but power system is on its way from brc. went with 2x20 amp esc and 2 2812 1500kv. iv proped it down to 5.5 as 6x5 was going to be well over 200 watts thats crazy on a plane that ways about 400 grams approx been trying to think as what the colour looks like and id say its British racing green so looks wrong. the pictures look more blue but its very green | |

| I'm running two standard motors with standard props 1550kv with possible 8x4 or 7x5 props either should be fine I dont see to many issues with torque roll on yours unless you apply to much throttle on take off. Its going to be a hairy maiden for us both m8 good luck on yours.

| i am getting a little worried, i think its going to glide like a brick. total flying weight will be approx 450g. the plan was for a plane with 48in wingspan with the flying weight of 460g. my wingspan is 38in | |

| well me and Pete made use of the weather yesterday afternoon. and my build got its maiden twice lol. first one i erm well....put it in a tree i was just going to see if the thing could take of from the ground and it left the ground and was all over the place. it was so tail heavy i was fighting to get to the trims and it went into the tree.lol. just a bit of foam missing from leading edge. so taped up and Pete did its proper maiden. needed a lot of trim to get it flying ok but as it was over weight it needed speed to keep it flying. so its being shelved and im on with the mk2 full size plan already. best viewed in hd[youtube]<iframe width="640" height="390" src="https://www.youtube.com/embed/xt8FirteayU?rel=0&hd=1" frameborder="0" allowfullscreen></iframe>[/youtube]
