I've cut away the broken sections of the wing on the belly and replaced with some more balsa.
I will be taking the model to an aeronautics engineer and Giant RC model builder for assessment on Sunday. He has agreed to install the crank shaft in the motor when it arrives.
This model WILL FLY again....sooner rather than later.

G'day all,
I have been pretty busy lately with work, and my various RC aeroplane projects.
About 6 weeks ago, I got my World Models 60"Zero back into the air. It is powered by a GWS 75 Nitro engine, which can be fickle, but no in flight engine failures yet.
I have been flying it as often as possible, and now have 14 flights on it.
5 of which were this past Sunday.

Not too long ago, I swapped a 90" Tiger Moth for a Ziroli 96"Zero.
The model was originally scratch built by Luke Cullen, a well known builder and pilot of large RC aeroplanes here on the Darling Downs. He sold it to my mate Ray Baines, who flew it for an unknown period, before he had to put his RC models away for 8 years while he concentrated on his farm.

Anyway, I have the Zero on my bench now and am working on the wing. On its last flight, Ray belly landed it and ripped the belly tank off it, which damaged the underside of the wing a bit. I have cut away the broken sections and am in the process of replacing those sections with some new balsa.

I purchased a new 5 cell, 6volt power pack to run the servos today, and the original futaba servos came to life instantly with nary a twitch. I had to adjust the flaps to make them even on deployment, and the ailerons are fine. I've cleaned up the wing surface, and lightly oiled the Robart air retracts with some singer sewing machine oil. Everything is going well so far.

I will be posting here as I make progress on this, my largest project to date. From what Ray tells me, the model flies beautifully, so I'm very keen to get her into the air.

To power her, I have been given a Zenoah G62 which needs a replacement crank shaft. I've ordered that from my LHS and will be getting a suitably qualified individual to complete the installation of that part for me.

For now, I have a picture of my daughter sitting next to the model at Ray's place prior to it becoming mine.

Should any of you have advice for me, please feel free to offer it here.

Finally had my second pilot arrive for this model.
I touched up the paint on him a little, and glued him in.
Also, When I glued the canopy on originally, I used a medium CA to secure the rear section of the canopy to the middle section. This caused a cloudy residue to form over the plastic panels.
When I had the canopy off for the installation of the second pilot, I used an aviation spray on plastic cleaner and polish which throroughly removed this residue. The results speak for themselves.

The Decals for my Hurricane arrived last week.
Once again, Callie has done an Excellent job. It never ceases to amaze me how accurately she can produce decals which fit perfectly where they're supposed to.
Case in point are the decals for the Tail of my Hurricane. RAF 601 SQN had a unique tail flash with their SQN crest in the white part. I sent Callie illustrations I'd found on the net, and only wingspan and ACFT length dimensions. She has produced the tail flash to fit PERFECTLY.

I had to remove the stock Squadron Code and aircraft registration numbers from the model. This was a bit of a dilemma in itself because the stock decals are water slide type and could be difficult to remove; plus, I'd read on the forum that other owners were having major difficulty colour matching paint. I had contacted Horizon Hobby for this info, but they said that it was a saleable part and were unable to provide the details (has anyone ever seen their paints for sale??)

Long story short...I discovered that by just rubbing my finger over the stock decals they would peel off with the friction.....but mainly only on the green paint, on the brown it also removed the paint. I took the cockpit to my local BMS Mitre 10 hardware store, and the guy there quickly matched the green perfectly, but then spent absolutely ages matching the brown. I was very impressed with his determination to match the colours perfectly for me .

I've now placed all the decals on the right hand side and removed /...Continue Reading

G'day all, well, I've been a little busy lately, and I've managed to more or less complete a couple of projects.
With the FMS Zero conversion to the A6M2-K 2 Seat Trainer Variant, all I was waiting on were the correct sized meatballs for the sides of the fuse. They have arrived from Callie and are perfect. I also completed the weathering and the effect is really quite pleasing.
Additionally, I finished assembly of the E Flight Hurricane and weathered it also.
I am waiting on some graphics to arrive from Callie so I can customise this model as the main mount of Australian Pilot Clive Mayers' during the BoB.

Here are the latest pics.

The attached pics show the dimensions of the under Carriage for this model.
Michael, will the WingSpan 100Degree electric Rotators go in here without too much trouble?
