Indeed I had not thought about the prop. Maybe there is some room for building a higher pylon ... Regarding the engine, today's .90 sized engines are roughly the same weight as .60 sized engines, so there is no actual reason to use lower displacement. Aircraft is big, it needs power for thoese windy days.

I know you've extensively used glow engines on your designs, especially the seaplanes. I now see that you have moved on to electrics.What is the main reason that has driven this ? Cost ? Airframe better life span (less oily mess) ? Cost ? Simplicity ? Glow engine tuning hassle ? You seem to have turned the page

There are many reasons I moved to electrics. It started designing electric powered models sometime in late eighties as a challenge. I was approached by Easy Built Company to design electric powered models to compliment their line of rubber powered kits. They gave me everything needed to build electric powered models. I always dreamed to build multi engine planes. Now I could accomplish that with less hassle, using electrics. As a technology of electric propulsion advances, there is less and less reason to power the models with glow engines. At the moment, the initial cost of getting into serious electric stuff is higher then glow. Despite of that, I like no noise, clean model, easier installation of motors and no ugly muffler sticking out. At this time I have only one North Star powered by glow, rest is electric.
Laddie.

Status: offline 		Laddie,
You' re quite right about electrics. There still remains a problem with them though : charge duration... It takes more than one hour to recharge these LiPO packs, and they're sometimes not that cheap, so having paris or more is difficult. I believe they'll improve in that area quite soon.

Keep us posted with your maiden

Status: offline 		Here`s mine - scratchbuilt about two years ago. I wanted a model that would work as a trainer, landplane, floatplane, camera plane, and maybe candy bomber. I labelled it 'VersaFli'

It is 70" span and was initially powered with an RCV 58. I just couldn`t get that engine to run well at all and have since replaced it with an old OS 60 FP. It is now a delight to fly off both water and land.

Construction is conventional balsa and plywood - covering is Ultracoat. Floats are foam core, sheathed with 1/16" balsa and then clad with fibreglass.

Status: online 		the pics of my plane wit the cart were in the early stages...the plane now sits in a float cradle and is lashed to the cart...the boat is a small kayak (the kayak works great but honestly i have never had to use it to retreve a plane!(i know im gonna regret saying that!) it is also lashed to the cart... not show in the pic is a side rack that i made to hold the barn doors...eh er a the wings so that when i take the plane to lake other than my own i can make everything in one easy trip the cart really lets a plane of this size be practical i can get it to the lake and in most cases push the cart right in to the lake to launch the plane...we all know its more fun to fly with others but now i can do it myself if needed thanks for taking intrest in the cart it really is a fun set-up

ORIGINAL: LADISLAV

The scale model of New Zealand amphibious plane called SHEARWATER. The wingspan is 80”. Powered by AXI 4130/16. The flying weight is 9.5 Lbs. The wing is foam and rest is balsa. The model is ready to be flown. I will try to fly it from the snow first. Right now all the snow is melting.
Laddie.


Laddie that is another Beauty ................... congrats green with envy ................... have you flown her yet .................. re the cof g if it got desperate could you not use a short shaft to shift the motor forward?? It would negate the duct a little however.
