Is there any autopilot capable of performing auto take off and landing of
fixed wing large RC plane ?

I would like to hear from anyone who has a Kavan Variable Pitch Propeller. I
don't necessarily want to buy one (though if they want to sell it then I
might) I just would like to get a general description and find out about the
operation of it.

I have spent a fruitless hour or more searching for 1/4 scale plans or kits
for a Cub or Super Cub.  I thought that Great Planes and SIG or even Hangar
9 did a 1/4 scale kit but though i can find some of these on U.S. sites the
size prevents them from being sent to the UK.  Does ...

I am building a 1/5 scale model of a Piper Colt.  I am planning to cover
using Dacron material and paint with dope to match my father's full-scale
plane.  I am looking for some pinking shears that will be at least
semi-scale for doing the covering... Any sources for scale pinking ...

Let me know if I'm smoking dope here.

I've got a hotliner sailplane I'm getting ready to put in the air.
Another club member had one like this and said it was hard to get it
on the ground.  So, I thought to myself - I'll use the flaperon mix
available in my XF421 TX to help with that problem.

Don't even have the maker of it but it's called a Doubler. Has no rudder
but two fins on each end of the stab. Does anyone have the correct CG
location. thanx

Following up information derived here and having contacted Pegasus Models,
they do what sounds like a very nice Balsa USA kit for £169.  They say that
this kit outsells other brands that they do.  Has anyone built this and if
so, which 4 stroke motor did you use?  Has anyone ...

Can anyone recommend a good (working) link that shows how to port a Homelite
25cc engine for more power. This will be going into an aircraft and I
believe the porting will make a significant difference to power output.

A fellow modeler in my club has the 48" version and is looking for a LiPo or
NiMh pack to replace the stock 7-cell 2100 mAh pack.  He's not interested in
burning up the sky but just wants something that will give him pretty good
duration and a modest improvement in performance.  ...

Anyone know of a R/C model of the ME 163 WWII German rocket powered
fighter.
