Default setting up Lanier RC Mariner 40

Just picked this up at an RC Auction last weekend.
62" wingspan
.61 OSfx
7.5 lbs
Manual
Looks clean inside... thought I might see water stains???
Looks like some fiberglass repair down the center..
the "hull lifters" are covered with fiberglass...? maybe they were trying formore turbulance??
I've been flying a foam electric seawind EP at our float flys. cant wait to fly this one... looks like a similar layout to the seawind. straight wing, motor is more forward on the Mariner.
much heavier !! more speed when landing?
Looking for any cmments/advice on this one. Any problem areas I should check?
How bout the engine? just fuel it up and try it out?
What are the chances of flying this off the ground? off the snow?

thanks

Steve

Hi Steve,
I have the big 120 sized Mariner. It's a great flyer with no bad habits. I didn't like the way it turns so I coupled a little rudder with the ailerons. Watch the step area for leaks. I glassed the belly on mine with a very light glass cloth to make it tougher. Make sure the front hatch is very secure because, if it comes off, it's in the prop. Screws, not magnets. Compared to a foamy, it's going to land much faster and require more space. It's a fun flyer. Good luck.
Jim

Jim, I was thinking on grinding off what he put on the bottom and doing like you said, an overall coat of .75 glass and epoxy over the bottom. Not sure why he fiberglassed the hull lifters? I would leave those as is?

I fly my Seamaster off grass all the time. It is similar in design to your plane, so give it a try. I was pleasantly surprised with the Seamaster.

wow- I don't like the fiberglass work on the bottom of the hull. That looks like it would unravel and make little needles of the glass strands.

I'd be really tempted to remove that, or at least to sand it as smooth as possible and to re-cover the bottom. Stripping the bottom and glassing it would be good, with a reinforcing doubler strip down the keel. Also, use much lighter glass cloth(3/4 oz). That glass cloth looks like the stuff that comes with a can of bond-o.

I wish I understood hull-lifters. They just look like they would cause drag. Possibly they scoop bubbles into the step to ventilate it - to defeat the suction.
Treat any comments I make regarding hull lifters as uninformed speculation.

Flying from grass or snow is no problem with floats. Do make sure there is not a gravel base under the grass or snow, and land as gently as possible.

One last thing:Early Lanier Mariners were reported to have a weak joiner between the elevator halves. Check/reinforce/upgrade that as appropriate.

I wish Grate Pains had not dumped the Mariner when they bought Lanier. It's a sweet flying plane. The one I flew, flew just like a Stik.

These like to fly / land faster than your seawind. The glass looks like an attempt to repair damage from rocks or some such. If it's still water tight, I would just leave it alone untill after flying it. Be sure to seal up the lifted covering on the vert stab, mine came off during a hot landing after the wood got soft from water. Also be sure to remove wing and set up a little fan to dry out any water that may have gotten in. The glue and wood used in mine was not the greatest, eventually the wing lost integrity during flight.

I have one and it's made very well and flies nice. As stated . depending one the age I would check the tail as there was a problem there that was fixed on later models. Looks like the previous owner was trying to take measures to beef up the hull . I fly mine off of snow as well as water and the hull is stock and shows hardly any wear. If I was going to glass it I would use lite glass cloth instead of the medium/heavy.
Otherwise the plane flies great , does aerobatics well, it does have a high sink rate though so be aware.
This is one I wish they would bring back into production !
