| This is a picture showing a flaw in the plan, the spar slots in the plan don't account for the displacement when they are cracked. Not a problem, but something to take into account. |

| Is that balsa or oak? Is this an older kit? When I get heavy C grain sheets I send them back to Guillow for better quality. So far good build. |

| Thanks - It's balsa, also brand new kit, and I have just started building flying models, what is "C" grain? any help will be very appreciated! |

| A/B/C grain refers to how the wood is cut relative to the log it was cut from. Check out this guide for a better description.
Incidentally, I just purchased a B-25 with half of the sheet wood soft and die crushed and the other half heavy/hard wood but with razor sharp die cut lines. I'm not going to build it to fly so I guess I'll try getting the die crushed wood replaced. If I was trying to fly it I would either need all new wood or to cut my own. |

| Thanks for the balsa info. I am using balsa left over from the Barrel for the Rat. Half of the width of 6 in x 36 x 1/16 sheets were so hard that I thought I might need a torch to cut it. Still the hard wood was better than the "pop corn" Balsa that Guillows sent with my Spirit! |

| Thanks for the info everybody! This kit was kind of like SteveM's B-25, in the fact that it had a very soft "A" grain balsa, and a hard "C" grain balsa, but I will make any parts that are too hard or too soft (I made the F2 ribs in the picture (they are the bent/cracked ones). |
