Back in my second BAR in the 80's I flew a lot of FSI motors. I had a lot of trouble using the thermalite wicks in the 21mm engines. In 1984 I tried using Estes Solar ignitors in them and had no more trouble. The only FSI motors I really had CATO problems with were the E60's.

I missed the poopy clay Estes motors as I was out of the hobby then. Good thing.
