I am a 402 pilot (Been out of it for a few years, ) I was practicing with my Excelsior and had a battery extension die on me and I piled it in and totaled it. I don't have the free cash this month to buy a new kit/arf/arc but I have a Goldburg Ultimate that I am building.
Now I know it isn't great for it but I recall a conversation with Dean Pappas at the 97 or 98 Glenn NY meet about stretching either an ultimate or a Sukoi. I was thinking of building the fuse with an extra 6 inches in it for better tracking and muddling along with this for the summer.
(better than nothing) till I can build a new 2 meter plane this fall/winter.

I will reuse my ST2300 in it, (with the carb mods and muffler pressure it runs great) so power will not be an issue.

Do you think 6inches will be enough or too much?

Again no funds for a new plane this month and I need to get back flying and the Ultimate is all paid for.

Thanks
