Yes, I had the D & B Kit and was it an engineering challange to get this ready to go. Upgrades consisted of inlet and exhaust ducting, gear placement, tail rigging and some strengthening. My T2-J (single engine Navy prototype) was powered by the Dynamax/OS .91/JMP II package, used the Spring air retracts with robart struts and contained all usable control surfaces. The jet can be seen on the SKS Florida Jets 2000 VHS tape. OH yes I used a 3 X 3 inch cheater whole
