Some years ago I built my first low winger, which was a Precedent Lo-Boy.
One unusual feature for the time was it's single mid wing section flap. It was a great aerobatic model, use of the flap in flight enabled some pretty hairy manouevres, and it also made landing a doddle.
I have seen adverts for the Precedent Hi-Boy and Precedent T2 around and am aware they are still avaliable, do any of you intrepid model aviators know if the Lo-Boy is still being produced, and where I could get my hands on one? even plans would be a help.

Hi Bill .As far as i'm aware the Lowboy is no longer available. Why not try a free add in RCM&E or even on this forum . You could also try a wanted add on the BMFA classified section ,its free and thousands of modeller look at the adds. Good luck.

Hi Bill, re: the Lo-Boy, yep it was a nice aeroplane, sadly no longer available but if you look at Black Horse Speed Air ( the green one) it is a lo-boy clone !
With mine i used the original torque rods soldered together and cut the ailerons in half and fitted a servo in to each wing panel so now i have flap( operated by the original aileron servo). I also fitted a cheap set of irvine mechanical retracts.
It does fly very similar to the original Lo-Boy, landings are nice and slow, and quite aerobatic when on full rate.
Hope this helps a bit.

A new member of our club purchased a Precedent Lo-Boy off eBay. Do any of you Lo-Boy experts have the following information to assist in setting it up.

1) position of the c.g.
2) total weight (model feels heavy)
3) approximate throws on control surfaces
4) recommended engine (OS40 2 stroke fitted)

Just reviving this thread.

 I have a Lo-Boy gathering dust under my desk at work (a colleague gave it to me), I haven't done anything with it as I fly electric and it is a heavy beast.  However, recently I've been giving some thought to getting it sorted with a large brushless and a nice big Li-po to use on the windier days (which, if you believe the Prophets of Doom, will be increasingly frequent in the future!).

 Anybody any experience of converting one?

A Lo-Boy that is, not a Prophet of Doom!

I have a Precedent Hi Boy kit, 59" wingspan, with a missing wing, it was given to me....Can't seem to locate anything to relace the wing...Any ideas..Maybe a foam core...Anyone know the airfoil shape..or will any flat bottom of the approximate size work....? Any help appreciated..

email is

Hoping to hear from someone.....joe in Texas

I don't know how many different versions were made of this Hi Boy, but this one is for a

.29-.40 size engine...When did they go out of business...Precedent Hi Boy...?

Thanks again...joe

I was going to say you could have my wing for free.............until I saw where you live!  I don't really do 'flying planes other people have built', it just doesn't seem right!

If you like I could take all the relevant dimensions for you and trace out the section.  Any use?

Yes..a tracing of the airfoil chord might be very helpful..maybe a could get a foam wing cut with the hot wire

with this. Didn't know the wing was missing out of the kit when I accepted it..I mean, Its all ribs.LE, TE,spars...nothing. Oh know what they say about gift horses..

If you can send the chord, I would be very can send to :

Will that work that way?..if not get back to me with whatever you need to send..

thanks again..joe

Sure thing Joe, no worries.  Probably won't get chance until early next week.  I'll take all the other critical measurements and some pics too.

One thing though, you mention ribs etc. but mine is a foam wing, as far as I'm aware that was standard (unless anyone knows different?)

Just realised Joe, you have a Hi Boy not a Lo Boy................ooops!  Guess mine is no use to you is it!

That'll teach me to read what you said (in my defence it is in a thread entitled 'Precedent Lo-Boy'!)

Yeah..I know its Lo Boy, but was closest I found with Precedent airplanes.`..This is a flat bottom wing, 59

wingspan...Is there any similarity?

Nope, this is 56" span semi-symmetrical.

anyone know the measurements for the CG for the hi-boy precedent? Also should the tank be fuel or not, wings on or off for measurement?

I don't know what the CG loction for the Hi Boy is, but i would expect it to be about 1/4 to 1/3 of the wing chord back from the leading edge, someone else may be able to confirm. The best thing is to find a club and ask someone there to check it. 

As for balancing the fuel tank should be empty as this means that the plane is slightly more stable when the tank is full and still stable as it starts to get used.
