The most funny thread about planes lacks
Hi friends
I informed [link]http://jet-hobbies.com[/link] of their plane "Fun Air 20" defects: 1 - I had to enlarge the firewall hole to push forward the tank and remove a lot of balsa to install it. 2 - I had to prolong very much the main landing gear legs to be able to install the propeller.
3 - I had to change bottom of the wings by another color to be able to distinguish it from the top.
I informed Jet-hobbies of all these defects. Their answer: "We sold a lot of these planes and nobody complained about them".
Perhaps it's true: we often are lazy. BUT THESE DEFECTS ARE VERY EVIDENT.
[:@]Manufacturers want always to be right. Let's try to inform them of their planes defects.
What do you think about?

RE: Let's inform manufacturers of plane defects
#1, I can see, but what size engine/prop are you using? if is it well above their recommended engine, making the stock gear too short and also requiring a larger tank? and #3, coloring isn't a defect, beauty is in the eye of the beholder! Lots of planes have identical top/bottom wing colors, especially ones that use clear covering.

RE: Let's inform manufacturers of plane defects
Hi friends
Dear rkramer
Are you in the pay of Jet-hobbies? I used the stock fuel tank, propeller 10x6 and this kind of plane requires a different color for top and bottom! When you are doing fast rolls or torque roll flying low, you must distinguish the top from the bottom fastly or you'll crash.
Don't say foolish things like Jet-hobbies.

RE: Great ideas for landing gears
You are right, Fly3d.
I also have "Fun Air 20" and what you said is all true: tank not to allowed to install the wings. I had to burn with a hot iron a lot of balsa. I had to enlarge the hole firewall to let the tank stopper go in. I had to lenghten landing gear legs cutting them and gluing two aluminum sticks. Before I tied them with copper wire. I also must change top color because last sunday I was going to crash the plane.
It cannot distinguish in full light.

RE: Let's inform manufacturers of planes defects
Thank you, Pilota-italiano
Finally somebody who tells the truth! You aren't surely in the pay of Jet-hobbies.
Another reflection: the most diffuse lack of planes is a weak landing gear (many planes are weak in the legs). Aluminum legs bend
easily. Connection system is the real weak point. Model racing cars have a lot of shock absorbers, landing gear no one.
Dear Manufacturers, you must invent shock absorbed landing gears, fixed in elastic way on rubber supports.

RE: Let's inform manufacturers of planes defects
For 3D models lighter is better, adding spring UC's make it heavy IMO.
Before you get shock absorbers, maybe you should practice your landings on sim??

There are shock absorbing legs, Oleos and such the like, you can pick them up easy but of course, you want to keep a 3D model light!

Dear friend Shahid
Fly 3d is right when says: "Connection system is the real weak point." To make the junction elastic, manufacturers should connect landing gears to the fuse by little rubber boxes with holes for the screws, like the junction of servos but bigger in proportion to landing gear size.
Has nobody else found other lacks in own planes? If lacks are written here, it's easier that manufacturers provide to remove deficiencies.

RE: Let's inform manufacturers of planes defects
Some of the improvements come from the pilot/builder. Like adding silicone rubber shock absorbing material between the landing gear and the fuselage of a UCD, or making a 5/32 wire gear for a profile fuselage. Improvements are part of the fun of the hobby.

RE: Let's inform manufacturers of planes defects
no-one got torque wire UC? simply use 8 guage wire and once at the plane bend 90 degrees to the legs, then after 3-4" bend inwards and hard mount, use clamps to hold the level part. the wire on this flat part will twist allowing the legs to spring. light and works great.
colours arn't the way for top/bottom vision, you'll recognize geometric shapes before colour and at a greater distance. large circles on the bottom normally do the trick. also make sure you're colours are opposite ends of the grey scale for better vision far out and in low light.

RE: Let's inform manufacturers of planes defects
Hello Flightwatch
Don't say foolish things like Jet-hobbies. You can add silicone between landing gears and fuselage but, as the screws are connected in rigid way, this system is no use.
I agree with Pilota-Italiano: "To make the junction elastic, manufacturers should connect landing gears to the fuse by little rubber boxes with holes for the screws". I disagree with him when he says: "like the junction of servos but bigger in proportion to landing gear size." No, in servo junction system the screws are connected in rigid way to the plywood.
In LANDING GEARS the screws should be connected only to "little rubber boxes". In this way the junction would be really elastic and would absorb the scocks.
Thanks to jroy for his evidence.

RE: Let's inform manufacturers of planes defects
Hi Fly3d
you are right and very intelligent. Manufacturers could fix under the fuselage two metal sticks to do this: \[=]/
= is the rubber box, section 3 cm x 1,5 cm - \[ ]/ are metal (brass? duralumin? ergal?) profiles that hold the rubber box with holes for screws. In this way the landing gear and the screws are free to rotate and can absorb shocks instead of breaking and damaging the fuse.
In profile planes I'd use a great solution. Instead of doing little holes for the screws of landing gear, I'd do two holes of 9 - 10 mm. I'd put into the holes two rubber "fisher" (I don't know if you call them in this way: they are used to fix brackets on a wall) and I'd use their
screws to fix the two legs of landing gear. It's a very good idea.
Ciao,

[8D][size=4]Hi people
[color=blue]I am still here. "Pilota-Italiano" is me, your old friend Italian Flyer.
[&:]And you write always too little. This thread is very important, try to say lacks of your planes.
Do you like my idea for profile and normal planes landing gears?

RE: Let's inform manufacturers of planes defects
Fly 3D and Italien Flyer, i think you are the same people. Stop wasting our time! The italian bloke has done it B4 and keeps on doing it.
I wonder if you really can fly a plane, bet you cant even fly a trainer, post pics if you can.
It must only be a "beautiful country" when ur not in it

everyone knows its the same demented person and if IT had any sense it would marvel at the simplicity of torque UC

RE: Let's inform manufacturers of planes defects
You want a shock absorbing undercarriage?
Try the ready available spring UC legs or tidy up your landings.
Alternativly try GRP for flexibility.
