Here is a link to Jag engines that reviews a Ryobi on a Hanger 9 stick. http://www.jagengines.com/Ultra31.htm Also go to the SPAD website and look at the Giant SPADS and specifically a SPAD stick using the Ryobi 31 (http://spaceghost.freeservers.com/whats_new_1.html). Should be videos with those also. I have a as yet converted Ryobi that I may use on an ACE Big Bingo. I would like to hear what you decide to do and the results. Good luck

Here is a link to the original Ryobi 31 powered Ultra SPAD stick. Looks like 81" span. Also converting to electronic CDI is good, reducing weight and improving performance.

A Ryobi will fly it fine, but it won't have a lot of vertical. Some performance mods to the Ryobi would help. The weight won't be a problem. The Giant Stik has a really long tail, and if you need a bit of weight in the tail to counter what the engine weighs, it won't be much... Just using some heavy duty servos on the elevator and rudder might be enough extra weight to balance it.

I at first had a Poulan 42cc on mine that flew well. I smacked it into some power wires coming in dead stick one time and crunched the front of the fuselage badly. When I rebuilt it, I made the nose 1" shorter, and now it flies with my homemade 48cc twin cylinder Echo engine and a smoke system.

Ok, here ya go....

Do a search for "Echo twin" and you will come up with a bunch of hits. There was an Echo twin 61cc made by the factory, this one is a 48cc that some of us here in the forum made out of two 23.6cc Echo engines and a custom crankcase. The crankcases are sold out. This one I set up on Gas/Glow, but could easily be set up to run on regular spark ignition. It sure runs sweet and smooth...

Thanks! It's a lot of fun, and there's that extra satisfaction in saying "I built the engine myself!"

Hi Bob!!!!!! Just hanging in there.
was out for some time due to work, illness etc. but I'm back with lots of new strenght and hopes!!!!
I am starting a new R/C company BAJA HOBBIES www.bajahobbies.com
my dear old R/C buddy just passed away on "Dia de Muertos" and one of his dreams was for us to own our R/C plane factory, so I am starting it in his honor.
As a matter of fact the Ryan Rebel is been re-named to the "Charly Boy" due to the fact that himself was the one that purchased the plan and him and I modifieded to what you and your brother have purchased and flown or are still flying.
So I am starting this plane factory with the Charly Boy and 100" wingspan trainer for a 26CC engine which I am importing from china.
I'm also distributing the RCGF line of engines, and another friend is building the Phoenix 8 semi kit for us to sale.Well i'll keep you posted on this venture.
So are you still living in PeƱasco? how is the family??? does your brother istill howns the Charly boy?????
Well buddy I'll kee in touch
Saludos from your buddy down in Baja.
Bill Pomplun.

Nice looking plane Bill.

So tell us why the Charlie Boy in stead of a Ultra Stick?

What are the physical differences?

How do they differ in performance?

What kind of package deal can you put together?

This plane is totally different then the ultra stick, it has 80" wingspan, 72" long, wheigs aprox. 12lbs (ready to fly) it is sturdier, has 2 piece foam wing joined by a T6 aluminum tube, you can put a 33 to 45CC gas engine and do al 3D stuff or put a 26-31 cc engine and do basic aerobatics or fly like a trainer.
I am offering the plane alone ARF for $175.00 as an introductory price or have it available with different power packages 26CC RCGF engine+plane = $395.00; Plane + 31CC Ryobi/electronic ignition(RCEXL) = $350.00; Plane + 45CC RCGF = $450.00
I can also have ready to fly just include your receiver for $200.00 extra on each power combo, this includes the following items.
Two 2500 NiMH battery packs
one 16X8 APC prop (26CC engine) or one 18x6W APC prop (31CC engine) or one 20X8 wood prop (45CC engine)
Five metal gear Digital servos plus one std. servo (throtle).
Two "Y" connectors.
Three 12"-15" servo extensions.
One Power distribution Unit (helps manage your batteries so receiver allways recieves 5.5 volts regardles of servo current draw).
One heavy duty switch with charging jack.
Installation fee.
of course this not includes Shipping and Handling as this varies from area to area (usually arround $45.00 to $50.00 dollars)
