Thank you all very much! I hope to finish my Great Planes Viper 500 this winter. OS 55ax and one of those newfangled radios.

Sounds cool Rog! You gonna be ok with no antenna on that radio??

I'm going to miss forgetting to put the antenna up.

That viper will be a fun plane. I had a Q500 years ago with a nelson 40 quickie motor and it was really really fast with that motor but almost too fast to use as a sport plane, i put a super tiger 50 in it and it slowed it down to a much more manageable all around fun plane. The 55ax will be perfect. Some guys were runnin piped 32's on them and that was a good combo too. I been thinkin about gettin another one as i have a jettfire 46 sittin here :-)

Not much to the airplane. I may have to beef up the rear fuselage. Have read they break in half on rough landings. Did you use v tail or rudder configuration?

Hey Roger Happy Birthday- good to hear some of you young kids getting to enjoy the "Golden Years" ( or is that the "Brass Years" ?) Just kidding partner, every age is Golden.

Sounds like you are going to have a "Rocket", that AX 55 will be a hauler.

Look forward to seeing you and the new rocket.

Thanks Tom. May have to revise decision on OS 55. Too much torque-not enough rpm. Maybe I should put the 55 in the Kaos and the .46ax in the Viper?

Stick with the 55 Rog. It will turn a 10-10 as fast as the 46 will turn a 10-7 or 10-8 and still give ya great static thrust for quik take offs. Theres no prop/ ground clearance for an 11" prop anyway. The 55 will give it great take off power and be an honest 140-150 mph plane. After having a couple Q's i really think the 55 will be perfect for ya. My Nelson powered Q went in the mid 190's but take off performance sucked with the 8-10 1/2 plylon props. I did beef up the rear fuse by running long strips of 1/4" x .050 carbon fiber down all four sides of fuse tho you would have to pull the covering off to do it now. I wouldnt bother with a seperate rudder as you still get decent rudder action from the ruddervaters on the v tail. Awesome plane!!

Oh......and run the same 55ax 10-10 combo in the kaos, u will dig that as well :-)

14 Re: Happy Birthday on 11/17/2014, 10:38 am

Roger Beltmann

Thanks for the info Dave. From what I've read most q500 planes use 9-8 or smaller props. Too small for the 55. A 10-8 should be about right. HP rating the same for the 46 and 55. Weird

15 Re: Happy Birthday on 11/17/2014, 11:01 am


Yep, if you are gonna race and want every last mph the 9-8 work good but even droppin an inch in dia from a 10 to a 9 the static thrust ya lose is amazing. Trust me a 10-10 on that 55 will kick ass and on a 4lb airframe vertical will be very unlimited. Over the years ive found os hp figures to be worthless.

Thanks Steve; Since I got glasses my depth perception is much better too! Never knew what I was missing.
