RE: house of balsa p51 .20
Thank You for the positive input. It would appear that building to the original plans and using good modern lightweight components might be the key. I already have 2 nice OS .25 FPs so one is probably going under the hood but the new Thunder Tiger GP .28 looks tempting. If anyone has any experience withthis engine please let us know. I may try putting one of my light weight high output .15s in it if I can keep the weight to a minimum.
