Hi Maurice, sorry for the late reply, but as EarlyBird has posted, the plan is on OZ.

Although my version does differ from the original in some areas, it is basically a Fizza.

Two other examples are flying at our club, they are quick at full chat, particularly the 4s version and they can be flown safely at very low speed.

Nigel Hawes also designed a larger version called Wizza, plan not on OZ but as a free plan in RCM&E would still be available.

My Fizza uses a 2830 1900 kv motor  8x6 prop  30A sc drawing 24A from a 3s 2200 lipo.

Thanks Ron, I will look out the plan.

Finished my first foamboard build. a Ki45.

60" span, 2 x 3536 1200kv motors contra-rotating 9x4 3-bladers from a little 2200 3S pack. Duration may be a bit short, but I have a few of them, so get more flights!

 

It would have been a quick build, but for time lost rubbing my chin as I got my head around foamboard construction, and 72 hours lost this weekend as Storm Eunice, or whatever we call her killed our power... It is, however, very low cost. 3 sheets of makerboard is about £13. 1 sheet of 1/4" balsa, and around 10 glue sticks. 

 

Covering is brown paper and PVA. No dope, paint is emulsion sprayed on. Matchpots from Homebase, and a bit of mixing, sprayed on with a small automotive gun with a 0.8mm nozzle, and edges softened with my airbrush. Panel lines are a sharpie and a white gel pen, weathering is a mix of dark grey, black and rust acrylic paint, well thinned and airbrushed. Some weathering down to aluminium is via a silver sharpie. The canopy frame is lined with aluminium tape and painted over. Natural handling wear will show the aluminium through it. Looks good from 6ft!

 

It's a 'fling and flop' job, hence the finger grips under the wing.

 

Weight ready to fly is a staggering (if you are used to conventional builds) 3lb 6Oz...

 

One day, we may get to fly it...

Why not? Reduces the P effect/swing to the left on the takeoff roll (if you are a bit fast with throttle stick or a bit slow with the rudder!), probably helps with spin recovery and should one motor quit (yes it does happen with electric!) helps with the wash off the prop along the fuselage to the fin/rudder.

 

Could have a discussion as to which prop should be on which side, but we could discuss that somewhere else.

 

PS -  Super nice model there Graham....fancy selling the plans ?

Thanks Chris.

 

Regarding contra props, what Chris said!

 

Regarding plans, er....

 

I printed an A4 3-view and took loads of measurements and then transferred the wing shape directly to the foamboard. Much of the rest was designed on the fly as i got the hang of how to work with the material. It's surprisingly easy though. @Eric Robson manages to produce far neater curved fuselages than my starved horse, but it is still reasonably easy to work and results are quick. It's also quick to see where something isn't working and try again.

 

I'd be more than happy to chat you through what I did if you take the plunge and have a go. Drop me a PM.

 

Take a look at some of the FliteTest videos, they really show loads of useful techniques and make it all nicely accessible.

My first ever power model but mine was Mills75 powered..........back in 1954

Mine as well. My first successful model aeroplane! Without it I wouldn't be here today.

 

I have always been a faddy type and I wanted to paint the fuselage purple but you couldn't buy purple dope so I mixed red and blue dope and it came out brown! It still flew well. ?
