Ouch, the cost of that turbine is way more than I expected. Its more than a bigger one. Oh well, she will have to stay electric.
Here is a lik to a build thread I did that will answer all your questions. I am using a Jetti 77, Medusa 36mm 1300 kv motor runnign direct drive, 6s 3700 batteries, 700mah mimh rx battery, 30 size retracts from Hobby lobby and mechanical nosegear from Robart(heavier one with 1/8 strut, not 3/32). Weight is around 5.5 lbs. Mounted the motor my modifying the existing mounting blocks slightly to raise them up a bit and then used a clamshell motor mount to hold it between the blocks. There are plenty of pics here.
TUMBLER, whoosh that was fast !!
a couple questions:
1. which ESC you got there ? whats the amp draw ?
2. which retracts ?
3. how did you mount the motor ?
