I would like to hear from some of you on this subject. I have a Great Planes Super Skybolt on the bench. It is rated for a 60-91 2 stroke. I plan on using a Magnum 1.08 in it. Has anyone done this? What is your opinion? Thanks

I dont see any problem with it if you can manage your throttle. No power on dives, power on snaps etc. For guys who use the throttle as toggle switch ( on or off ) I'd say no. One drawback to using a larger engine is more weight and more wing loading. Something to consider.....

Thanks for your views. I am not quite ready for 3D yet. What I am looking for is unlimited vertical performance. I am beefing up the stucture where I can. Right now the fusalage is completely built up. I am very excited about this airplane. Again, Thank you for your opinion.

It won't be too much power, I have a Magnum 1.08 in a Global Freestyle 46. The plane is rated for a .46 2-stroke or .61 4-stroke but it was pathetic with a Magnum .61 4-stroke, ok with a YS .63 4-stroke, and is nicely overpowered with the 1.08. I haven't gotten the motor broken in yet, it seems to be taking a bit, I have about 1/3 gallon through it yet and it still 4-cycles even set lean. Anyone run a Magnum 1.08? It's a true ABC piston/sleeve so it should take a little longer than a nickle plated liner. My weight went from 6lbs 1oz up to 6lbs 10oz. It's not light but it IS fun! The thick wing seems to produce enough lift that I haven't noticed the difference in weight very much. In this pic it still had the YS .63FZ engine. -Tom

I have two of the Super Skybolts. With a two stroke I needed to add weight to the nose. So, I removed the 2 stroke and installed YS 120 on them. Unlimited vert. with a 16X6 prop. One of the best inverted flatspinning planes I have. Loads of fun to fly. A little heavy with those 4 strokes.

THanks for all the info. You have really helped me out. When it is finished I will post a picture on here and let you know how it went. Thanks for voting too.
a 1.20 is a must if you want to put smoke on er it will need the extra power to haul everything around a friend has one with a 1.20 and smoke and it flys real scale like and with the smoke it just adds to the effect
I have one with a 15 year old OS 120 on it. I fiberglassed and painted the plane and the kit's already fairly heavy. Not quite enough power to hover in this configuration swinging an APC 15x8.
The plane's incredibly overbuilt. I wouldn't worry at all about the 108 overpowering it, although I'd heed the above warning about prop clearance. This plane ain't got much.

Barryb,
I am considering F/G and paint the skybolt. Or fabric or film. What do you think? I would love to glass it but my glassing skills are'nt up to par. I can't do 3D yet. How did yours fly straight aerobatics being fiberglassed?

I bought one when they first came out - I like the way it looked on the box and built it to match. I powered it with an OS 120. I had a few problems with an early kit - the biggest problem - and I don't know if they fixed it - was that the landing gear flexed way too much. With a 15x8 prop, I kept chewing up the gound and prop whenever it flexed. I built the plane real light and with the 120 I considered it overpowered. As far as 3D, the plane is too small to do what my 35% Extras or Laser can - it just isn't the same. Because it is small and quick, I pulled the engine and gave to my buddy for his Cub, the Skybolt is in the basement for sale.

I consider my skybolt powered correctly with the saito 120 and the 108 would probably work just as nicely. They come out on the heavy side and have lots of roll coupling when rudder is applied. I dont consider this a 3d plane. The wing attachments are fairly solid but would never hold up to lots of blenders. Hovering for mine is difficult because of torque pullover and rudder coupling. snaps and spins nicely. If you want smoke you have to plan on moving the servos back into the tail as much as possible. There is not much room left at all when set up per plans.
