ventura_kelley Posted June 16, 2010 Share Posted June 16, 2010 I picked up a Quickboost F4U-7 Corsair engine for the Hasegawa kit, and while the packaging says it's for this kit, it is drastically smaller in diameter than the kit engine. It's beautifully cast, but it's about 3/16 inches in diameter smaller than the Hasegawa engine, the crankcase is almost the same size as the prop hub, and it just looks funky in the cowl. Is the Quickboost engine underscale or is the Hasegawa F4U-5/AU-1/F4U-7 series overscale? Quote Link to post Share on other sites
ventura_kelley Posted June 16, 2010 Author Share Posted June 16, 2010 This is a "C" engine right? Is the Vector R-2800C better (size wise)? http://www.ultracast.ca/products/Vector/48...004/default.htm Or is there some other option? I'd been hoping for separate pushrods on the front row of cylinders if possible. Quote Link to post Share on other sites
Uncle Uncool Posted June 16, 2010 Share Posted June 16, 2010 Is the Quickboost engine underscale or is the Hasegawa F4U-5/AU-1/F4U-7 series overscale? Hmph... judging by the photos, me would tend to think it's more the latter, mate. Quote Link to post Share on other sites
ventura_kelley Posted June 16, 2010 Author Share Posted June 16, 2010 Hmph... judging by the photos, me would tend to think it's more the latter, mate. I'm not so sure now. Check this out: http://data3.primeportal.net/hangar/don_bu...5n_06_of_14.jpg It looks like that version of the R2800's crankcase should fill the cowl pretty well and should be considerably larger than the prop hub.

ventura_kelley Posted June 16, 2010 Author Share Posted June 16, 2010 http://www.primeportal.net/hangar/luc_colin3/f4u-5nl_122189/ Anybody know if the Vector engine is better? Quote Link to post Share on other sites
ventura_kelley Posted June 16, 2010 Author Share Posted June 16, 2010 Then again... This one makes the Quickboost engine look right. http://www.primeportal.net/hangar/domeric_...t/f4u_corsair_/ This is confusing. Quote Link to post Share on other sites
TF51GREGWISE Posted June 16, 2010 Share Posted June 16, 2010 (edited) This under-scale problem with quick-boost products seems to be serious. I did a review for IPMS on the Ar234 engine- severely under scaled and will not fit at all... I pointed this out in the review so I don't think it will be published. And I have the engine for the Me 262 and it is also under scaled. but not nearly as bad. Edited June 16, 2010 by TF51GREGWISE Quote Link to post Share on other sites

ventura_kelley Posted June 16, 2010 Author Share Posted June 16, 2010 Oh, and I've come to the conclusion that the Hasegawa Corsair prop hub is too squashed looking. Anybody know of a better regular Corsair (not the F2G) prop? Quote Link to post Share on other sites
