I pinned the firewall and added epoxy to all of the joints. There was good use of triangle stock in the corners. I sealed all of the hinge gaps, I used CA hinges and they were very close anyway. I am thinking about adding some tail brace wires but haven't done it as of yet.

In my haste of assembling I forgot to use loctite on the motor mount. When I went for my second flight I noticed the motor was moving when I put my starter on the spinner. Good thing, 1 bolt was missing and another loose. It is all ready now, everything has been triple checked and will be flown on Monday after I get home from Vegas.

Hello Guys

I built a SS in 2007 and put a magnum 91 4s that balanced the plane perfectly. I love the way the plane handles specially compared to another bipes. Long story short I got caught too much with the 3D bug and only flew my profile. I took the engine off and put it in another plane (I might need counseling for doing this to a SS). The engine crankshaft broke and send it back to global and they fix for free but after two days of flying the crankshaft seems to have broken again (I haven't opened the engine yet but the crankshaft spins freely like an out runner motor).
I decided not to get a new magnum so I wanted to know what engine would be better, I was considering a saito 100, 115, 125 an O.S. 91 or 110, or a YS 110 also how you think a saito fg20 gas would I work (I'm kinda worried about the extra weight of the ignition pack, Horizon has it listed for 30.1 oz wich is 7.7 more oz than the magun 91).

I now have a YS 91FZ in mine and I like the extra powe, but if I were going to buy an engine for it today, I would get the new OS 110

I've got a Magnum .91 sitting right here... actually have 2 of them. The other one is in a GP Extra300.. I'm going to try and hold out, and save some chips for the OS 1.10... it only seems like the right thing to do.

Does that include the weight of the ignition battery? I'd be thinking about prop clearance, too.

I think it's really hard to buy a bad 4-stroke today. Well, ever since the OS 70 Ultimate and FL both disappeared... It's not a bad time to be a 4-stroke lover!

This is true. Although the Magnum does run perfectly, I do believe the OS would have the definate advantage though, with newer technology, and lightweight design to say the least.

At $399 for the OS vs. $189 for the Magnum, it is a tough bullet to swallow... but overall in the end the Skybolt/OS 1.10 has got to be an awesome combo.

I'm not knocking Magnum's at all, matter of fact, I think they're great. Mine are very reliable, easy to maintain, and have given years of service(with many more to come).. and a Magnum in the Skybolt is sure to give positive results...but this ARF is just too pretty for me ... and I'm just itchin to get a hold of one of the 110's.. I haven't had a new glow engine in about 8yrs either(which is about the last time I built a new glow-powered plane).... so it's about time. I just might even sell one of the Magnums to offset the cost a bit... dont' know.. I'll probably have to sell a few more things to offset it... here we go again...

Hey Dgrant,

Why don't you save fewer chips and get the YS110? It's cheaper than the OS and you will never have to worry about wanting more power....

David.. thanks much for that info.. do you happen to have a link to a YS dealer for some comparisons? Some of them might be interesting to note first-hand... IE..weight/prop recomendations/warranty/etc.. I'm not opposed at all to looking into other power-plants. I am seeing the OS 110 on several sites now. I might even look around for any reviews of it. I miss the reviews they did in the old days of RCM.. that was great info on new products.. and comparisons(although the internet is..well... you know)..

Mike.. how do you like your YS in your SS? Comparitively to the .91 OS you had in there.. is there an extreme noticeable difference?.. .. and if so where does it shine or lack compared to the previous powerplant?

How about the new saito 20cc gas, would it be too much power / torque, what prop would be best

Thanks

da Rock

Ask yourself a couple of questions and you have your own answer.

How much does your engine weigh compared to an average 60 2Cycle?

Will the prop that's going to suit your engine have enough clearance for the airplane to land with the prop turning? To help you answer, look at pictures of the Skybolt and note that it's already got about the shortest gear you're going to see on a 60size model.

hey maybe one of them folding props would be the ticket here eh Rock?[sm=bananahead.gif][sm=lol.gif]

Just love this plane [ or I should say both of them ] MM

Oh, its cheesy, all right. It also works. What I did on my Chapman Cap was fly the plane and BE sure I didn't have any elevator differential issues; then I JB Welded those pushrods together. It held up for quite a few flights, and is still flying AFAIK (I sold the model last year).

What I'm wrestling with right now is engine choice. I have a not-so-used 91 Surpass (an older one with the silver rocker cover), and a Laser 150. The Laser is too big/heavy for the Bolt, but I cannot help but think that the 91 Surpass isn't quite enough. No, I don't do 3F (Flip-Flop Flying). If I want to fly something like a helicopter, I'll get a helicopter...

It didn't used to be this difficult to decide on what new model to get after a lay-off. But many of the "tweeners" that are perfect for the Laser 150 have disappeared.....[&o]

A member in our club just put a zenoah 20 in his. He started with an echo 1.3 but switched. He uses a 16 x 8 prop now and he's got it up to just over 9000 rpm since it is broken in. He did these mods:
NECESSARY SKYBOLT MODS:

(1) Fiberglass the outer perimeter of the Skybolt firewall
(2) Move the elevator & rudder servos to the rear of the fuselage.
(3) Add flying wires to the tailfeathers.
(4) Add a stand-off box for the engine
(5) change the fuel tank stopper to GAS compatable stopper change to Tygon fuel line.
(6) Add an access hatch for the ignition.

. He has a thread on our Great Southwest Aeromodeler's club website. He seems to like it a lot. Here's a pic...

Ooooh, I like!

RPool,

I like that setup too but where is the exhaust exiting the cowl? Do you have a picture of the front of the plane showing the muffler and exhaust?

Thanks

RPool

Sure; it was hidden by the prop in the other photos...

DGrant

RPool... Nice little velocity stack sticking out the side. I love those things.. they look so racey.. and actually that engine doesn't seem to awfully bad in that.

Whats the flight report on it I wonder? Very curious.. not that I see myself doing something like that with my SS.. but it does seem to open up the envelope a bit on engine choice... hmm.

That Zenoah is pretty cool in the SS. I have a OS 91 FS in mine and it is perfect for this plane. (graupner 14-7 prop) I just finished putting a AR7000 rx in her and "tightening up" the covering after the first winter storage. I hope to get out later this week to put the first flight of the year on it. (If i can put my helis down long enough, LOL darn things are too much fun) To all you new skybolt owners, enjoy your new skybolts becuase they are a fun, relaxing, good lookin, just plain 'ol sweet flyin plane.

summerwind

hey guys,
there is one of these on the for sale boards right now with everything but a Rx, and it's defiantely a steal.

The Skybolt is a fantstic flyer. I installed a Saito 100 twin upfront, other than adding an extention engine mount it flew straight of the board no extra trim or balance wieght needed.
It looks and sounds great.

Check my pic gallery

C-eagle1 Do you have any video of your SS flying with that Saito twin????? I would be very interested to see it if you do.

Saturday maiden flight of my Skybolt.
Setup is all "standard" with and OS91 engine.
As I gave power, she tracked straight with no bad tendecies, and no right rudder correction. A touch of up elevator ad she was flying! Trimmed the model (elevator only) and flew around for a while to get a little confident. What a great flyer! She does exactly what you tell to do, nothing more, nothing less..
Time to land, reduced power to slow her down and , alligned on the runway.... that's all I did and she made the most beautiful 2 point landing I ever seen!!
What a grat machine... that's my new everyday flyer!
