RE: Ultra RC 87" Yak Build and Fly
Arvind, I have had this same set up in 2 other yaks so far and I have had no problems... I also talked to Da and you are right that is what they recommend. They also said if I am not experiencing any problems then go ahead fly that way. So I do not know, this is how my plane balanced out with the tuned pipe so I am living with it.
I do have the stock and large Jtech that I could switch to if I do not like how it flys. I figured that my set up is the same as Extreme Flights 87" in that they used the tuned pipe with everything up front???(no smoke in theres) I'll give it a go and report back.
