Hobby King Skyfun - speed thread

Hello all....

I am starting a thread on the SKYFUN flying delta which is available from hobbycity to see what everyone has been doing with theirs.

I bought one a while back and just got around to putting it together.

I didn't bother with the supplied power system, I put a HET 3W motor driving a 4.75 by 4.75 prop on the back, a Pentium 40A speed controller, polyquest 4S 2250 lipo to see what would happen.

I have flown it a few times and todays flight is on the YOUTUBE link below.

My first impressions are:

The thrust angle is wrong, I need to add some upthrust. The change in trim from full power to no power is around 5 clicks.

The plane is nice and stable, very easy to fly.

The speed is okay but I want to know how to make it go much faster!

I lost the plane today when the clear canopy blew off. The battery and all electrics followed it out and so the plane just fluttered down like a leaf. No damage at all except the clear canopy separated and I lost one of the fins.

It's a bitter sweet crash... I know it was not pilot error but I have lost the receiver, fin and the battery. Everything else got found after a search.

I did actually find the battery but as you can imagine it was in no state to re use after a vertical drop from altitude....

As an aside can anyone doppler the video to check the speed for me?

The video is quite shaky and hard to watch but I had a new camera man today.

I am new to high speed foamies so be patient with me! I know there are some big stryker threads etc but there is almost too much information to wade through.
