From what I can find out Daler Rowney mount board is relatively heavy compared to true foam boards.

I applaud you ingenuity but at 60" span it had better not weigh 6-10 lbs! More like 2-3lbs maximum and even then I am not sure a motor from a RC car would do.

Thanks for the info.
It may seem a bit odd that I have put the 2200mAh so far forward when the spec suggests a 1300mAh. The reason is that that Hobby King glue a chunk of lead, 0.83oz (24g) inside...

The problem with the HP115 is it is an unusually draggy airframe. Rising drag as you slow down and rising drag as you speed up so its effective speed range is quite limited. :concern:
