TOPIC: Hyperloc 835

Hyperloc 835 8 years 5 months ago #511

I was thinking of converting this kit to have three 29mm motor tubes or three 24mm surrounding one 38mm. ( I haven't checked size there yet. ) Also, adding the public missiles CPR3K. Anyone know if these company's parts are compatible? Does anyone know where I can get custom centering rings? Usually I have to make my own.

Doing the math, you can have the following possible combinations: (1) 1-38 with 2,3 or 4x29; (2) 1,2,3,4 or 5 x 29mm. My advice is avoid a 24mm in the cluster--not much lift for your dollar. Also, it's nice to have a cluster with as many flight options as possible: for example, the 38 +3x29 gives only 3 combinations: 38 only, 3x29, or all motors. The 38 + 4x29 gives 5 combinations: 2x29,4x29,38,38+2x29,all motors. In general, a central motor with an even number of outboards gives the maximum number of possibilities. IF you select a central 29 and 4x29 outboards, you can fly on 1,2,3,4,5 motors-you could also do that with 38 + 4x29 if you put a 29/38 adapter in the central mount.

Avionics bays: the PML setup works, but is expensive. I would not invest that much money in a cardboard airframe. Instead, get the avionic bay kit from www.giantleaprocketry.com for under $30. Giant Leap also sells centering rings. So does www.locprecision.com Either one will make cluster rings to your specifications. Several of us in the club have built avionics bays, and can show you how to do it. I build mine from scratch anymore, to save money.

Anyway, have fun with it and post if you need some help along the way.

Have fun with it.

As to altimeters for your bay, I like MissileWorks: easy to use, reliable, reasonable price. Lots of people also like PerfectFlite. Can't go wrong with either one. Both are barometric, dual deploy units. If you also want to airstart your cluster, I would consider a G-Wiz unit. They are sold by Hawk Mountain (www.hawkmountain.ws/). G-Wiz has a third channel to do staging or airstarts, but it is more expensive. One nice feature of the G-Wiz is it uses BOTH a barometer and accelerometer, so it doesn't need to do the "go to sleep" routine to handle Mach 1+ flights. But adding both drives up the cost. I hate it when I get what I pay for :)
