Dido the excitement about using a Thunder Tiger Pro 40 in one of the Q-40 racers.

A fiberglass and foam Q-40 kit can be built for about the same cost as a 424 kit. I generally figure the kit with Jett motor mount can be delivered to your house for about $165. The wood, glass cloth, paint, and other materials run about $100 per airplane. This totals about $265 per airplane, which is the same as some 424 models.

I started a Proud Bird thread and I am currently going to build 2 models. One will be powered with a Thunder Tiger and the other with a conventional 422 motor (probably Jett).

Don - Keep up the work on the Stinger and other kits. They should be a lot of fun for not a lot of money.
