Bonesmalone Posted April 14, 2012 Share Posted April 14, 2012 Hi guys, could any of you kind folk supply me with a measurement from the firewall to the front of the prop driver please. This is on a kit built acro-wot not the new ARTF airframes. I only fly petrol now but really enjoyed my old acrowot and am wondering if I can fit one of the new ngh 9cc petrols in...... Thanks in advance Tong Bryan Quote Link to comment Share on other sites More sharing options...
Eamonn Fahey Posted April 14, 2012 Share Posted April 14, 2012 From instruction manual "...engine installation length of 4 1/4" (from back of spinner to bulkhead). Quote Link to comment Share on other sites More sharing options...

Eamonn Fahey Posted April 14, 2012 Share Posted April 14, 2012 Instructions also state "To accomodate extra length of many larger 4-strokes, bulkhead can be moved back 1", reducing cowl overlap to 1/4"." Let me know if you need any other info. Quote Link to comment Share on other sites More sharing options...
Bonesmalone Posted April 14, 2012 Author Share Posted April 14, 2012 Thanks once more Eamonn , with a maximum of 5.25 inches to play with I have more than enough room to fit the Ngh gt9 petrol in, I feel a build coming on Quote Link to comment Share on other sites More sharing options...
