No Mark, It's the Rear induction. The engine runs very well, very smoth transition, but it's early day's yet. I've only made 4 flight's But am very impressed.
As for prop hub to firewall, I was also concerned about this as it doesn't seem to mention it in the online specs, It's 5 1/2 inches I think I'll double check if you like?
But works out just right on the Hanger 9 Spitfire, comes out 3mm in front of the cowling. Would some pics be useful?
The only problems I encountered. Were:
Engine mounts were quite a bit wider than the predrilled holes, so new holes drilled and strenghening added as one of the holes was way too close to the edge!
Fuel tank bung and clunk had to be replaced for Gas friendly versions.
I needed two breathers also as filling the tank through the felt clunk kept pushing it off the tubing.
New hole drilled in firewall for HT lead.
The cowling also needed extensive surgery as the exaust sticks out quite a bit, no bad thing I suppose as I know it'll run nice and cool.
A bit more work than fitting a standard nitro but i think it was worth it.
Hopefuly I'll get some more flight time next weekend after sorting out some nigaly problems found on the maiden.
