K&B 7.5cc DF on Whiplash ?'s
I have a K&B 7.5 with what Ithink is the newer carb. It is NOT the version with the cast in cooling heatsinks on the side of the carb. For balance,the motor will be mounted pretty far forward, but still need to gring alot of material out for the carb to clear. If i raise the engine by 1/4" i think it will alleviate much of the clearancing. Will this cause some odd flight problems since the thrust line will now be higher than designed.
Thanks
Jeff

Spacers under 7.5 on Whip
Hi Jeff,
I guess we missed this one today. You can make a pair of maple hardwood blocks 1/4x1/4 sq. and elevate the motor. It will not change the flight characteristics at all. We tried to allow for every type of motor on the Whiplash, but I guess we missed that one. I guess we had a different version of the 7.5 DF. Anyway, try the blocks, they should do the trick.
