Default Water landing

Hi !

first post for me I'm french... so I'm going to try my best to write understandable english

I've made a little beginer aircraft like this one:



My idea is to make a system which can water land.
Do you know if water landing kit exist?
Or maybe a water landing plan helps me to make it myself ?

Thanks for your help

If it is a 40-size airplane, you can use these:

One question – since this is your first post in RCUniverse, do you have any flying experience? Many times people come here thinking a Cub is a trainer, but it’s not a good RC trainer.

And I do agree with Mr67Stang - your english is much better than not only a lot of teenagers over here, but many adults too.

Hi

it's not this exact model... I've tried to find a model which seems to be the same on google.. but mine is a Pilatus Porter like this one: (it's a beginner model sold by a pro)



1meter large for 80cm long.
I'm going to buy a float system to make my landing easier than on the ground.
Is the 40'' floats too large for my model dimension?

Thanks for congrats about my english
This community is awesome! Many many people over here!

If the fuselage is 80cm long, you probably want the 24" floats here:

Sounds like he wants to fly off grass with these, should he strengthen the bottom with something to take the abrasion? Seems to me the balsa would get torn up fairly quickly. Nice selection of floats.

I don't think so. By "Water land", I believe he means "To land on water"

yes, sorry

I want to land on water with floats

I'm now asking to the guy in south east michigan how can we process... and if it's better to take wood floats than plastic ones.

In fact, I don't know if the weight of these floats will be problematic for my actual motorisation...

Interesting little Turbo Porter. Chip it seems this may be your first airplane and you are using it for a trainer. It appears to be a small electric and I suspect that more conventional floats may be far to heavy for that airplane.

If this is you first and the idea of using a float plane just to make it easier to land is a poor idea and almost always gets very expensive especially if you are trying to teach yourself to fly.

Its always the best plan to start on wheels then later go to floats.

If you are having problems on wheels with that airplane its because the main gear is far too far forward for good ground handling. For any ground run of more than a few feet it will want to swap end severly. Also landings will be very bouncy with gear like that. That airplane is a poor trainer.

I have to 2nd what John Buckner said. The main landing gear LOOKS very "springy". For floats the landing gear/float supports definitely will need to be stiffened up.

If you are just learning to fly (especially if you are trying to teach yourself) learn to fly from land 1st, then go to floats.

The Porter is going to be marginal as a trainer. If your porter has flaps, I suggest setting them down about 10%. This will allow you to land at a slower speed. If this is an electric plane, you need to investigate light weight floats for the float flying. Also, if it is an electric, I strongly suggest putting an "outrunner" motor in it and using lipo batteries. MANY planes come with a brushed motor that is usually just marginal for power and the nimh battery packs are typically about twice the weight (or more) of an equivalent lipo.

I need to explain myself more.

I finally take some photos of the plane I've made. (yes, I was lazy).

This is not my first fly and I'm not teaching myself to fly The resseler of my materiel is teaching me.
I'm learning on a simulation system too.

I manage to land with normal wheel... there is no problem.

But I've no field to fly near my home... but a large water plake, that's why I have this idea to setup floats on my aircraft.

Is it very difficult to land on water?

I think it's more difficult to take off. You have to be very careful to keep the wings level!

Nice plane! It kind of looks like a Hobby-Lobby mini Telemaster... with some added graphics.

I don't think it is THAT much more difficult.. The consequences of not doing it right however are a bit steeper! Be carefull to make sure the plane balances properly with the floats on it.. wings level on takeoff, use the rudder gingerly on takeoff as too much will cause you to dip a wing into the water.. My Cub has the small eflite floats on it and flies pretty well...

Also noticed his is a 3 channel (No ailerons). It will be harder to keep wings level on take off.
