Default yet another Capiche thread - mine

Here is my version of the Capiche built from the plans using balsa and my own construction methods rather than using the CNC pack. It was cheaper and lighter, and I had loads of balsa looking for a home. The main difference is the way I built the fuse - typical construction of 1/16 sheet sides with ply doublers from front back to the wing seat. Wings, talplane, fin are almost identical construction to plan.

The actually aerodynamics of the model are as per plan, same shape, same incidences, same right thrust etc etc etc. So essentially its just a slightly lighter Capiche.

Cowl, and canopy were from Nexus, and the carbon undercart is from Carbon Copy - looks superb and is very light.

Total weight came out at 3lb 15oz, around a 1/4 to 1/2 lb lighter than the cnc pack built ones according to the Capiche website.

Power is an Irvine 53 with an apc 12.25 X 3.75 prop, which gives it unlimited vertical.

First flight nearly ended as a disaster. The tailplane which was built exactly as per plan - ie 1/4 balsa sheet failed at the bottom of a high G loop where each half joins the fuse. Fortunately the elevator joiner held it together and I landed safely. I cyanoed it back together and braced it with closed loop wire. So far no more problems. Apparently the CNC packs use medium to hard balsa, I used soft stuff.

Flight performance :
Once I had the C-of-g back it became a really good 3D model, which is why I built it in the first place. Knife edge loops are easy, as are waterfalls, harriers, and parachutes. Flat spins are best done with a bit of power on to keep the tail down. Blenders are ok, not quite as good as a CAP232.

Hovering is fairly easy, I dont have the ability to do torque rolls yet, but with practice hopefully I'll get there.

Rolling circles are very good with this model, as you can do them quite slowly and have enough time to think about your control inputs.

This model has had a lot of publicity when it was launched and I was a bit sceptical of all the hype. However, hats off to the designer, its a really good 3D model, and will also do pattern style aeros too.

My colour scheme was copied off one of the models on the Capiche website, so appologies to whoever I stole it off !
