First kits can be scary but it is well worth it when you see it lift off the ground the first time.
I have not built the 4 Star but I am putting the final touches on a Sig Hog Bipe.
I found the the wood cutting and parts fit to be excellent. The kit is well designed and the pieces self align pretty well. The instruction book was well written and pretty complete. The plans and the parts matched each other pretty good too.
Making the huge assumption that the two kits are similar in the above mentioned categories I think you will be able to build the 4 Star as a first kit and have a rewarding experience.
There are several build threads on the 4 Star and there should be a lot of good support on the group if you need to ask questions.
Since this is your first kit build don't get carried away with making to many modifications, build it per print and it will fly great.
