Angle valve engines will not fit inside any of the standard F1 or HR2 cowlings without a LOT of surgery. Heck, it's hard enough to get the parallel valve engines stuffed inside them.I’m curious if the extra HP of the angle valve motors counteracts the extra forward CG as compared to the parallel valve engines in the Rocket? debating whether to look for an angle valve rocket to purchase.
That's what I was wondering, was if it even drops in easily enough with cowling headache and maybe cooling challenges.Angle valve engines will not fit inside any of the standard F1 or HR2 cowlings without a LOT of surgery.
