UH 15P vs rqriley Tri-Flier

[CDN HoverNut]

hey all!!
can anyone out there tell me the differences between the 15P and the
tri-flier (http://rqriley.com/tri-fly.htm).
I have the plans here for the Triflier, but was wondering which set of
plans would give me a better idea of how to build this craft (I'm assuming
they are the same thing somehow!). If anyone out there has built one of
these puppies, and has put together a web page showing construction
details....a link or 2 would be greatly appreciated. while I'm here....what
are your opinions of the 10F as a first trainer type craft for a 6 year old?

tia,
Tim

tim,

the rqriley tri-flyer is a uh-15p being sold under license from universal
hovercraft, with permission. the uh-15p is the basic design, rqriley provided
more detail for the rich and unimaginative, down to the padded seats and all the
nitty gritty.

if you want plans to tell you how to build the thing down to where you should
put the fire extinguisher, get the rqriley plans. if you want something that
tells you how to build what's important and not much else, then get the
universal plans.

by the way, i've driven this craft. it was extremely fast. holds two adult men
side by side. i didn't take it up to truly high speeds, but got it to around 65
or so with plenty left. i've ridden in it with the then-owner driving, maybe a
bit faster than that. he wasn't pushing it all the way either.

sorry, didn't read your whole post.

a 10f is a good starter craft. they can be fun even for a 240 lbs man (me) to
drive, though in my case it would never get far from the boat ramp, and only
upstream of the car.

build this one before you build your 15p, you'll make fewer mistakes on the one
that is sickeningly fast.

by the way. don't build heavier because you don't think the structure is strong
enough. the most common mistake is to build heavier because of disbelief in
the structural abilities. during construction the craft will be wiggly and
flimsy, but when you get the whole thing together it's quite rigid. follow the
plans, you'll get a very fast, very fun craft.

Hey Tim, I got a question for you. I have the 15p planset and was told by a
holder of the triflyer set that the stringers that form the top of the
cockpit walls and the top of the lift duct area are not shown as being
doubled up for the lift engine mounts. They are shown on my planset as
doubled up for about 50 some odd inches, something like R-1 through R-3
can't really remember but I think R-1 is the front, it is on my T4, so the
doubler stops at the cockpit spanning three ribs or two open areas. True?

The 10f will get you hovering faster because of the short build time but the
learnig curve is not there due to the foam construction, I say get building
the big'un.

Ken, up to 240 now huh? better get that 18 sp finished up! hehehe

gee thanks, david!

more importantly on the 10f is learning to drive a hovercraft on something that
won't kill him if he messes up. the 15p is a righteously fast machine. i can't
remember exactly what john had on his when i drove it, it was either 60 or 80 hp
if i remember correctly. acceleration was pretty good even with both john and
me in it.

by the way, my 12r did well enough with both me and a guy that weighed 280 or
so. that's technically over the max even before you count gas and tools and
whatever else was in the cockpit. ben was so nervous i couldn't really get it
moving (he had just wrecked his craft) so it was a bit sluggish running slow
like that.

just got a compressor up and going this weekend, and borrowed a heater for a
while. maybe i can get the garage cleaned up and then start working on that 18.

me in it.

I guess I can understand that point, I built using just the 10hp thrust for
that reason. I will have to add that there have been times in my hover
learning curve that I really wished I had more power to use for avoiding
various things. There is the wind factor too where power is a must. To me
more power is more options, sharper turning and to an arguable degree much
safer if used wisely.
To do it over I would go for the horse power and try to keep my finger off
the throttle for awhile. ya right! Hey! you started with a 98hp craft and
your still alive after all. I'm quite sure I'm preaching to the quire here.

Cleaned up? I thought you just bought that place!. Here I had you pictured
the young single guy, (maybe a little skinnier) with a new house, garage
with hovers handy, maybe some rudders and props hap hazardly stored about
the living and dining room, prop hub candle holders, quick sammitch for
dinner then off to the hover shop/garage to work with no nagging
wife,,,,,,,,,,,,,,,,,,,,,,,,I will have to find some one else to live
vicariously through. :-(
