Hi, im building one of these too, can anyone identify the Exaust pipe shown in the picture on the box or in the manual???

Ive put a YS 120fz in mine and re-inforced the undercariage area and front bulkhead with carbon, also done away with the elevator pushrod and got my self a MK dual elevator crank with a 6mm carbon pushrod with Dubro heavy duty ball links.

If you are going to use a pipe check the diameter first, as theres not a lot of room under the belly pan.

Thats why im trying to find out what pipe they used!! and ive tried mailing them with no luck?

Thanks
