Holy cow....I usually target just over 2lb AUW for that size warbird! I'm constantly amazed at the range of weights that these correx creations will fly at

A little video of the SPAD flying. Right around the 1 minute mark, I roll upright after a low inverted pass, and the SPAD Stik almost met its doom This plane is a hoot to fly! Coroplast and Adams Foam Board are two of my favorite building mediums. I like a nice balsa plane as much as the next guy, but the low financial consequence flying is always fun!!

Mitsubishi A6M Zero

Span: 1200mm (48")
AUW: 890g (~2lb)
CWL: 7.6
Power: HXT DT750 motor with 11x7 prop and 1300mAh LiPo

This one has provision for retracts and split flaps, but I've not got round to trying them yet.

Mugi Tea Racer

This one has been on and off my build list for a long time....I think the Mugi guys created a plane with very elegant lines. But the jury seemed to be out on whether it was a decent flyer or not. Anyway, I finally got round to trying it. Incidentally, I enlarged it by about 10% and made the fuselage lighter.

Specs:
Span: 900mm
AUW: 550g
CWL: 8.0
Power: 2826 2200Kv park jet motor with 1300mAh Lipo (3S) and 6x4 prop.

It certainly did not fly 'out of the box'. In fact I destroyed 2 fuselages before I got it to fly nicely. Though to be fair the first was my fault (taking my eyes off the plane to adjust the trim) and a dog attacked and mauled the second one. If you look carefully at the first picture, you can see the claw marks on the left wing

Once trimmed out it does fly pretty well. It is a bit twitchy in pitch (Mugi does warn that it is) and its not as fast as I expected. But it does have an unexpectedly good speed range and stall behaviour is not bad at all. In summary, its a simple build and nice size for a 'throw in the car' then 'throw around the sky' performance plane. May be worth experimenting with some hotter set ups in the future.

I kept it the original 100% size.

Increase the motor to an inrunner 2500KV and go up to a 5x5 prop.
THEN SHE SHUNTS.......

Plastic Polaris

The Polaris thread in the foamies scratch-build forum must be one of the most popular on RCG (http://www.rcgroups.com/forums/showthread.php?t=922465). Its been on my build list for a long time, but just as I was about to start cutting the foam, it occurred to me that I might be able to make one from correx.

I had to make a few changes to the design to suit correx construction and to mitigate the extra mass of correx, but the result is a fantastic park and lake flyer. Its certainly not a 'simple' SPAD, but using correx gives a much tougher plane that still flies incredibly well and is unusually versatile.

The most complex part of my build was ensuring that all correx joints would be 100% waterproof...but if you not planning to fly off water (or are not as worried about leaks as I was) , it could be quite a simple build....in essence its just a Mugi with a fuselage and tail.

Span: ~900mm (larger than the depron one)
AUW: ~750g (About 150g heavier than the depron version)
WCL: 5.9 (Same as the depron version)
Power: Turnigy 2826-2200KV with a 6x4 prop and 1300mAh Lipo (same as the depron version).

Here is some video of my having some fun with my 'Plastic Polaris' at my local park. I highly recommend this plane!!

Plans (for the foam version) are on the first page of the original thread (http://www.rcgroups.com/forums/showthread.php?t=922465 ). Discussion on my modifications and pictures of the correx build start at post 24848 (http://www.rcgroups.com/forums/showt...2465&page=1657). I think its best to keep all questions and discussion on the original thread as the average Polaris flyer is probably unaware that a SPAD forum even exists...and several of them have useful insights.

There appears to be some real hoodlums in that shot.... Particularly those fellows from Idaho Falls..... Rough crowd.

EDIT: that must be pre-race, all the planes appear to be in one piece
