| r90 with JR Super Gracy FuseHello,
Just fitted the JR super gracy fuse to my r90. It fitted like a glove, lotsa room for everything (extended radio tray to move 'c of g' forward).
The quality is amazing and thanks go to Masa at rc-champ in Japan.
On the first flight it was near perfect, except for the engine temp. This seemed a bit high and actually stopped after an auto while trying to re spool.
I'm using- ys90r, 20%cp/nitro, 7.9-1 ratio, enya 3, remote mixture servo, handmade enclosed shroud for head and maybe 1600headspeed(lotsa smoke too). Local temps around 20degC, just above sea level.
Engines being running sweet without fuse ie, never hot and lotsa power(bearing done 10 flights ago).
I richened it up and was slightly cooler but needs more airtime.
Should i try enya 4? more holes in fuse? a seperate pc fan? more nitro? head shims? any more suggestions.....
regards,
David |
