I've got a 4*120 kit coming in the mail right now.
Engine is going to be a Ryobi 31cc.
I have searched and done a lot of reading on this conversion. I just can't seem to find any really specific numbers.
One guy says he cut the firewall back and had to add lead to the tail---but he doesn't state if he used servos in the tail or not. Kinda useless to know how much he cut the firewall back when he doesn't indicate if he used servos in the tail or not.
Another guy will tell ya he used 2 hi-torque servos in the tail and had to add lead in the tail to balance. But he doesn't indicate if he cut the firewall back or not.
I need
specifics guys.
PLEASE
How much did you move the firewall?
Did you put servos in the tail or not?
How many servos in the tail?
2 elevator servos? 1 rudder servo? 1 elevator servo? 1 rudder servo? Rudder is pull-pull on the CG? What? What did you do?
Did you use a mount from wacker engines? 2" or 3" mount?
PLEEEEEASE post
specifics on this mod with the Ryobi 31cc engine.
PLEEEEASE.
Thanks very much.
LOL He couldnt stand it! My 2 posts got him thinking about that 120 and he just had to get one! Send the build pics!!!!!!!!!
I know it.
I've had the 4*120 before and it's a great flying bird and an easy builder. You got me thinking about it and I just couldn't take it. Had to get one.
I've got the Ryobi parts and a couple older Ryobi engines here--but I'm waiting on the new Ryobi from harbor freight.
I might put a C&H ignition on it--just to lighten the engine. Kinda defeats the purpose of a cheap engine--but I don't care. I'll build it and fly it with the magneto first--but if I think it flies heavy, then I'll order the C&H unit.
I am thinking about covering it in fabric. Haven't done that before, and it's TOUGH stuff. It really takes a beating much better than plastic covering.
I'd like to modify the wings--and make it a 2-piece setup with aluminum tubes. My truck bed is only 73" long. It's a lot of work, and I don't know if I'll do it. But, I am seriously thinking about it.
Thanks C Heath. Ya got me interested in one of my old favorites again.
My wife just shakes her head and smiles.[:-]
