gp viper 500
 

So i decided to get another viper 500... first one crashed on maiden : (

need advice on engine... I wanted a jettsport but will the viper take it??

or an os 50sx or 32 sx

any advice??

thanks

Why not go with a TT Pro .40? It runs well, is favorably priced and you will be able to enter 424 rulebook events if you like.

not really interested in racing. don;t live in the us anymore... compared to the os 32 and 50, how is the tt40???
thanks

how bout a webra 55??

RE: gp viper 500
 

What's wrong with the engine you had on the first one? I know in Texas they're using 428 motors on Vipers.

RE: gp viper 500
 

If your not gonna race it really dosen't matter. I would choose the one that will make it balance easier.

Lessons learned, what happened in maiden, what caused the crash?

RE: gp viper 500
 

no idea... flew great but came in for landing, and about 20 ft above the runway it just pointed down... guess I came in too slow... don;t know.. lol

Hi!
Webra .40 GT is the strongest running standard .40 engine available using a standard silencer and 80/20 fuel (which it trives on).
It turns a 10x6 Graupner cam prop (or old gray model ) or RAM at 14000 rpm or more , this can no other .40 engine do except Jett or Nelson.
Do not use a big heavy .50 or .55 engine.
Balance is no problem. Move servos and reciever /battery as far rearward as possible ...if requiered.
Balance should be where Great Planes suggest. Think it is 3" from leading edge.
Why not compete?? It's the most fun you can do in R/C...

i would love to compete... but i live in brasil... no pylon racing here.. at least I don't know af any... im thinking the 32sx with jett pipe... maybe 120mph???

RE: gp viper 500
 

I was running the first one with 46ax and tuned muffler... not quite as fast as I want.. engine broke on the crash... : (

RE: gp viper 500
 

That plane is not easy to tip stall unless you pull elevator too heavily when landing, but still its very gentle move it does. Were you sure about CG was right? I wouldnt fly with new one before knowing what went wrong with old one. It is waste of time to repeat the error.

Get in touch with Darrol Cady. He went to Brazil and pylon raced out there. He has an article at his website.

Neither the 32 or 50sx will be faster than the OS .46 AX you had on there.

RE: gp viper 500
 

the 32 sx won't be faster than a 46ax??? why is that??

thanks nanu... I'll look for it over here... should be lots o fun..
